CHAPTER 1: Introduction

Congratulations on purchasing the XAP 800, a highly advanced twelve-by-twelve

digital matrix mixer with Gentner

Distributed Echo Cancellation®,noise

cancellation, and audio processing. It uses an internal macro language and 32 user-

definable presets to quickly adapt to a variety of teleconferencing and sound

reinforcement applications such as distance learning, teletraining, telemedicine,

courtrooms, conference rooms, boardrooms, hotels, and houses of worship.

In its most simple form, the XAP 800 is a mic mixing matrix. As such, all mic

mixing parameters can be customized and any input or combination of inputs can

be routed to any output or combination of outputs, with attenuation adjustments at

each cross point.This allows great flexibility in accommodating a variety of

applications and requirements.

The XAP 800 features numerous functions which greatly enhance its

performance and flexibility. For example, it can gate mics on and off when the

sound within a mic’s acceptance pattern reaches a certain level.

The XAP 800 monitors each mic independently, observing ambient levels and

making decisions based on each mic’s environment.Thus, the input for a mic

located in a highly reverberant part of a conference room is gated, mixed, and

processed to compensate for the changes in that area and reduce echo and noise.

This improves audio quality and decreases the possibility of feedback.

The XAP 800 facilitates local and remote PC setup and diagnostics, logic

outputs, and automatic gated mic operation. Mic inputs can be individually

customized to gate on and off as you want, while automatic gain control keeps the

overall sound level consistent. Eight of the 12 channels can be configured as an

automatic microphone mixer.

Adjustments in routing, level, and other functions can be made through presets

activated through a closure on the rear panel, an RS-232 serial interface, or a

control panel on the expansion bus data channel.

The XAP 800 features eight audio processing blocks, each with 15 filters.

Each filter can be configured as a parametric equalizer, high pass, low pass, CD

horn, high shelving, low shelving, all pass, or crossover. This allows you to tailor the

XAP 800’s audio response to optimize the audio quality and fidelity characteristics

of a wide variety of sound reinforcement systems.

CHAPTER 1: Introduction

Product overview

Introduction ~ New Features

Technical Services Group ~ 1-800-283-5936 (USA) ~ 1-801-974-3760

The GPIO (general purpose input/output) allows switching among any of 32

user-stored presets.This gives you real-time flexibility to meet a variety of

reinforcement requirements.

Network-based interconnectivity allows up to eight XAP 800s and XAP 400s

to be connected and controlled as a single unit, allowing microphone coverage in

applications requiring up to 64 mics.

The XAP 800’s Macro Pro™ scripting language allows the unit to function

without the need for an external controller. However, it can be easily interfaced to

an external controller via either of the two RS-485 ports.The unit can also

interface with a PC through the RS-232 port.

New Features

• Virtual references. The XAP 800 now supports echo cancellation summing.

Four user-definable virtual references are provided which can use multiple

signals as the echo cancellation reference point without sacrificing an analog

output. This added flexibility further enhances echo cancellation performance.

• Improved noise cancellation. Our industry-leading noise cancellation keeps

background noise to a minimum while retaining top-level voice quality, echo

cancellation performance, and full-duplex capability.

• Front panel gain and mute control. Now gain and mute adjustments can

be made from the front panel. Using these controls allows you to make quick

volume and mute changes without connecting through G-Ware.

• Safety Mute. The new Safety Mute button on the main G-Ware toolbar

allows you to mute all outputs with one simple click if feedback or audio

problems occur during the configuration process.

• Preset and Macro Passwords. You can now password protect your presets

and macros to prevent unauthorized changes.

• Clear Matrix. This new button on the Matrix Screen makes it easy to clear all

cross point cells in the matrix. Simply click the button and confirm the action.

• RAMP serial command. The new RAMP serial command (see page 123)

gives you greater control over gain adjustments. You can specify the rate at

which the gain increases and decreases as well as the target level.

to the command set for the XAP 800 and can be used for common functions

such as volume control, muting, preset change, room combining, etc. Devices

can be connected to either port.

For instructions on how to program the control and status pins, see the

GPIO section on page 77. The default settings allow control and status of

inputs, outputs, volume, and presets. These pins are active low. The 32 presets

can also be activated via these connectors. For pinout and default

information, see Appendix B.

E. Outputs 1–12. These three-pin Phoenix connectors are for connection of

twelve line-level balanced outputs with three-pin Phoenix connectors.These

outputs are typically used for connection to VCRs, tape recorders, amplifiers,

codecs, phone hybrids, and other audio devices.These outputs may be

configured to contain any combination of gated and non-gated inputs. The

nominal output level is 0dBm.

F. Inputs 9–12. These Phoenix connectors are for connection of up to four

line-level inputs. These are typically used for connection of VCRs, tape

players, CD players, and other audio sources.They can be routed to any

output or multiple outputs. Nominal level is 0dBu.

G. Expansion Bus In/Out. This RJ-45 connector is part of the expansion bus

(E-bus), which allows up to eight XAP 800 or XAP 400 units and up to 16

XAP TH2 units to be networked together. The E-bus consists of two buses:

one for control, the other for passing audio and mic information (see Control

bus, page 7). Using Cat 5 twisted-pair cable, you can separate adjoining units

up to 80 feet (24 meters). See the diagram on page 11.

I. RS-232. This female DB9 serial port is for interconnection between the XAP

800 and a PC, modem, or other custom remote controller. For serial

protocol, see Appendix B: Connector Pinouts.

Expansion bus

The digital mix-minus expansion bus (RJ-45 LAN) is used to connect up to eight

XAP 800/400s and 16 XAP TH2 units, where the total number of microphone inputs

does not exceed 64.The maximum distance between interconnected XAP 800/400 or

PSR1212 units is 80 feet (24 meters). Connecting a XAP TH2 must not increase the

cable length between two PSR1212s, XAP 800s and/or XAP 400s beyond 80 feet.

ClearOne recommends that category five twisted-pair (10BaseT LAN) cable be used.

The expansion bus (E-bus) allows audio routing between destinations on the

E-bus network.The E-bus contains 12 independent digital audio buses labeled O–Z

which can route mic or line level inputs in any combination across the E-bus

network.The O–Z buses are divided into two groups (O–R and S–Z) based on their

capabilities and default settings.The E-bus also contains four PA adapt/acoustic

echo cancellation reference buses, four global gating buses, and one control bus.

• O–R buses. These four audio buses are defaulted as the mic mix buses; they

can communicate the NOM count and mic mixing parameters across the

network to other XAP 800s. All gated mics are routed to the 0 bus by default.

• S–Z buses. These eight buses are defaulted as auxiliary mix buses.They are

used to route auxiliary audio, such as from a CD player or VCR, to and from

other units on the network.These buses are also used as mic mix buses when

NOM count is not required.

• PA Adapt/Acoustic Echo Cancellation Reference buses. These buses

allow an input from a XAP 800 to reference an output on another linked

XAP 400/800. See PA Adapt and AEC Reference on page 33 for more

information.

• Global Gating Groups A–D buses. These mix-minus buses are defined as

microphone gating groups which support first-mic priority, maximum number

of mics, etc. and work across all linked XAP 400/800s. Unlike the audio

buses, they contain only mic status and gate parameters. See page 41 for

more information about gating groups.

• Control bus. The control bus is an independent channel from the E-bus’s

audio channel; it uses a different pair of wires on the same E-bus cable.This

allows control information to pass even if the units are not using the audio

link.The XAP 800 supports the full set of commands through the control bus.

To connect the unit

1. Place the unit in a standard 19-inch rack and attach it securely.

2. If you are using a custom controller for control and status, plug it into the

DB25 Control/Status A or B port [D].

If you are using an external RS-232 controller, connect it to the

RS-232 port [I].

3. Wire the inputs and outputs to the XAP 800 using the provided three-

terminal Phoenix push-on connectors. These connectors are designed for easy

wiring; simply insert the desired wire into the appropriate connector opening

and tighten down the top screw.

• Inputs 1–8 [B] Mic or line level inputs

• Inputs 9–12 [F] Line level inputs only

• Outputs 1–12 [E] Line level outputs

4. If you are using a ClearOne Remote Panel, wire it to the RS-485 port [C]

using the provided four-terminal Phoenix push-on connectors.

5. Plug in the XAP 800 to complete the installation.The power output [A] will

operate at any level between 100–240VAC and 50–60Hz.

If you are installing only one XAP 800 and are not connecting it to any other XAP

or PSR1212 units, you have completed the hardware installation.

Expansion bus connections

Using the Expansion Bus ports (RJ-45), you can connect up to eight XAP 800/400s

and 16 XAP TH2 units, where the total number of microphone inputs does not

exceed 64. Make connections between units in daisy-chain fashion using the short

RJ-45 jumper. If your units are further apart, use category five twisted-pair cable.

The maximum distance between interconnected XAP 800/400 or PSR1212

units is 80 feet (24 meters). Expansion bus cable length is calculated between

XAP 800s/400s and PSR1212s. The cable connecting a XAP TH2 to the network

is included in the cable length between the XAP 800 or XAP 400. For example, if

the cable from the XAP 800 to the XAP TH2 is 50 feet and the cable from the

XAP TH2 to the second XAP 800 is 50 feet, then the total length between the two

XAP 800s is 100 feet which is beyond the maximum 80-foot limit.

To create an expansion bus network

1. Plug the expansion bus terminator in the Expansion Bus In connector of

the first unit in the network.

2. Connect the RJ-45 jumper cable (or Cat 5 twisted pair cable) to the

Expansion Bus Out connector of the first unit in the network and

Expansion Bus In connector of the second unit. Continue connecting units

in the same fashion.

3. Plug the expansion bus terminator in the Expansion Bus Out connector on

the final unit to complete the network connections.

If the E-bus network is not connected properly, the front panel LEDs will

flash on the units that are physically connected to the network. To correct

the problem, check for broken connections and reconnect the expansion bus

cables.

Device IDs

Once your expansion bus connections are made (and if you have more than one

XAP 800 at a site), you need to set up a unique expansion bus device ID number—a

network address—for each XAP 800 on the network. As shipped from the factory, all

XAP 800s are set to device ID 0.

To assign device IDs

Press the front-panel

Enter

button, then scroll through the menu until the

System

menu is visible.

2. Press

Enter

, then scroll through the menu until

Device ID

is visible.

3. Press

Enter

, then scroll through the eight (0–7) options.When the desired

device ID is visible, press

Enter

to select it. (You can also set the device ID in

the Unit Properties window of G-Ware software see page 25.)

4. Repeat this process for each XAP 800 on the expansion bus network.

Mixer mode

There are two mixer mode settings: slave (default) and master. A master unit is not

required in a networked system and in most installations, all units will be slaves.

Master units ignore audio from upstream units.This prevents audio from being

received from units above the master unit in the network. However, global control of

the system is still maintained by whichever XAP 400/800 or PSR1212 unit is

connected to a control device through its RS-232 or RS-485 ports. Control is not

affected by master/slave designations.

In Figure 2.5, the third unit in the network is a master. It prevents the audio

from the first and second units from being passed down the network chain.

Likewise the second master unit in the network will not pass on the audio from the

unit before it.The third unit provides system-wide control through a connection to

its RS-232 port.

To select a mixer mode

1. Press the front panel Enter button and scroll through the menu until System

menu is visible. Press Enter to select the menu.

2. Scroll through the System menu and select Mixer Mode.

3. Select the mixer setting you want to use.

Repeat for additional units.

If the same device ID is assigned to more than one

unit on the E-bus network, the Meter LED “+12” will flash red, the Mic LEDs “1,” “2,” “4,” and “8” will flash green on the affected units. To correct the problem, change the device ID on one of the conflicting units.

the MINIT serial command (see page 116 or the G-Ware software. It cannot be set through the front panel LCD.

✍✍

You can set the modem password using the

MPASS serial command (see page 117) or in G-Ware (see page 26).

✍✍

Flow Control (hardware)

The XAP 800 uses the RTS and CTS pins on the RS-232 port to regulate the

transmission and reception of data. You can enable or disable flow control on the

front panel of unit and select the flow control type in the Site Properties window of

G-Ware (see page 23). If you select On (default) from the front panel menu, select

Hardware as the flow control type in the Site Properties window. If you disable flow

control on the front panel, select None in the Site Properties window. When None is

selected, the XAP 800 ignores flow control, making the connected external control

device ensure that data is not lost. Software flow control (Xon/Xoff) is supported by

the XAP/PSR units and is only used with a pass-through device, such as a modem.

To avoid communication errors, ClearOne strongly recommends that you

connect all DB9 pins and enable flow control when connecting to a PC.

Enable Modem

This parameter configures the RS-232 port for connection of a modem.When On is

selected, the XAP 800 will send an initialization string to the modem on power-up

and require a password before data transfer is allowed through the port. When Off

(default) is selected, the password is disabled.

To use the XAP 800 with a modem

1. Match the baud rate of the modem to that of the XAP 800.

2. Turn off Serial Echo on the modem.

3. Turn off the modem’s response mode (e.g., no OK messages, ring, etc.).

4. Enable auto-answer on the modem.

Matrix Screen

The Matrix Screen is used to route audio to one or more destinations (outputs,

expansion bus, or processing). Any number of connections to outputs can be made in

the matrix.The Matrix Screen can also be used to access the Input, Output, and

Processing configuration windows by clicking on the buttons along the top and left

sides of the routing matrix.

A colored cell in the routing matrix marks the intersection or cross point of

the routing from input to output. The color of the cross point cell identifies the

input type: yellow = gated mic input, blue = non-gated mic input, and green = all

other inputs.The amount of attenuation is also shown in the cross point cell. Black

cell are restricted routing paths which prevent E-bus and Processing channels from

being routed back to themselves.

The numbers and letters along the top and left side of the matrix show the

cross point coordinates. The input number or letter and the output number or letter

will be highlighted blue for the selected cross point.

All inputs and outputs are labeled to make it easier to identify channels.

Audio is routed in the Matrix Screen (see Figure 3.20 on previous page). To access

the Matrix Screen, click on the Matrix button on the Flow Screen.To return to the

Flow Screen, click the Flow Screen button.

The XAP 800 routing matrix has 32 possible input sources and 32 output

destinations, with level control at each cross point. Any input or combination of

inputs can be routed to any output or any combination of outputs. To clear the

matrix, click the Clear Matrix button located above the Routing Key.

To route an input, click in the routing matrix at the intersection between the

input and the output. A mic input can be designated as gated (yellow) or non-gated

(blue) by clicking repeatedly in the cross point. All other input cross points will be

colored green.

Expansion bus O–Z routing

Audio on any XAP unit in the E-bus network can be placed on the bus or taken off

the bus and routed to any destination within the unit. The XAP 800 has 12 digital

mix-minus buses:

• O–R buses are defaulted as the mic mix buses and can communicate the

NOM count. Gated mics are default routed to the O bus.

• S–Z buses are defaulted as the auxiliary mix buses. They are used to carry

auxiliary audio such as that from codecs and XAP TH2s. These buses are

used as mic mix buses when NOM count is not required.

Process A–H routing

There are eight processing blocks on the XAP 800 (Processing A–H). With these

processing channels, you can apply filters, EQ, or other processing settings to an input

or a group of inputs which can then be routed to a single output or group of outputs.

See page 49 for more information on processing settings.

The

Speech Leveler

is a compander that is optimized for speech audio. It

quickly equalizes the difference in speech levels in the room without bringing up noise.

If you use AGC with the Speech Leveler, set the AGC Response Time to >2 seconds.

AGC

adjusts softer and louder input audio to a consistent level that you select

(the target level).The target level range is from -30 to 20dB in 1dB steps. The

default target level is 0dB.

Set the

Target Level

first, then apply the amount of maximum gain that you

want the AGC to apply to the signal. Maximum gain range is 0 to 18dB in 1dB

steps. The default value is 18dB. AGC occurs after the gain and filter settings in

the audio signal path.

The

Active Gain

meter reflects the overall gain at any given moment. Click

the white box next to the meter to enable it.

The

Response Time

adjustment determines the total AGC engage/disengage

response time.The Threshold determines the decibel level at which you want the

AGC to engage. Setting the threshold toward the higher end of the scale (near 0)

reduces background noise to a greater degree. The Response Time is measured in

milliseconds. Target Level and Threshold are both RMS.

P Pwr (Phantom Power)

Phantom Power toggles the phantom power on and off. Phantom power is an

auxiliary power source to power certain types of microphones.The XAP 800’s

phantom power voltage is 24VDC. Default is On.

If you select a

virtual echo cancellation reference

, the Virtual Reference window

will open.You can also open this window from the G-Ware toolbar.

Use this window to select which signals will be used by the four Virtual

Reference points.The routing matrix portion of this window cannot be edited. Virtual

references are used when you need to reference multiple outputs. For example, if

you have stereo outputs (L, R) near a block of mics, you would want the mics’ echo

canceller to reference both the left and right outputs. By using a virtual reference,

the echo canceller will be able to reference both signals.This means you don’t need

to use a dedicated output to combine signals.

Or, you may have mics routed to the PA output but you don’t want the echo

canceller to reference this audio. By using a virtual reference, the echo canceller

can sample all signals routed to the PA output, minus the mic signals.

To create a virtual reference

1. Select the input signals you want included in each virtual reference by

clicking the cross points.

2. Because AEC requires a physical output reference to track output gain

changes, you need to select an output reference for AEC to function properly

with a virtual reference. Use the lists at the bottom of the window to select

which output you want AEC to use to track gain changes.

3. Click Close to exit the window.

Non-linear Processing (NLP)

The Non-linear Processing (NLP) feature increases the power of echo cancellation

for difficult acoustical environments. NLP features four settings: Soft (6dB),

Medium (12dB), Aggressive (18dB), and Off. Use NLP with care; corresponding

trade-offs can include suppression and half-duplex operation. Default is Soft.

Meters

The Echo Return Loss (ERL) meter on the Acoustic Echo Canceller window shows

the coupling between the reference signal and the input to the echo canceller—the

ratio of the two levels. It is an average meter that updates only when a signal is

present.

The Echo Return Loss Enhancement (ERLE) meter shows the loss through

the echo cancellation and non-linear processing chain—the ratio of the two levels.

It is an average meter that updates only when a signal is present.

The Total Echo Reduction meter shows the total ERL and ERLE reduction, in

decibels. It is an average meter that updates only when a signal is present.

The NC button on the selected input in the Inputs 1–8 window opens the Noise

Canceller window.The noise canceller reduces ambient noise in the signal with no

noticeable degradation in signal quality.

To use noise cancellation, click Enable Noise Canceller, then adjust the

Cancellation Depth to the setting which provides the best combination of low noise

and maximum speech clarity.The attenuation depth can be set in 1dB increments

from 6dB to 15dB. Default is 6dB.

The noise canceller default is Off. When noise cancellation is enabled, the light

on the NC button illuminates green.

Filters

The Filter button on the selected input in the Inputs 1–8 window opens the Filter

Graph setup window. Each mic/line input has four configurable filters that can be used

as filters or equalizers. By default, they are not enabled and the filter types are not

defined. Below is a description of each feature in the window.

Active Filter

Active Filter selects among filters on the graph. Note that no filters exist until you

click Add Filter (see Figure 3.32) to add filters to the graph.

increments. Rolloff is 12dB/octave. Level is fixed at 0dB.

• Notch. Center frequency range is 20Hz to 20kHz with resolution to 1Hz or

four places (whichever is larger). Bandwidth is from .05 to 5 octaves in .01

octave increments. Level is fixed at -80dB.

• PEQ (parametric equalizer). Center frequency range is 20Hz to 20kHz

with resolution to 1Hz or 4 places (whichever is larger). Bandwidth is .05 to

5 octaves in .01 octave increments. Level range is -15 to +15dB in 0.5dB

increments.

Frequency. Use Frequency to select the center frequency (in Hertz) for the filter you

are configuring. Range is from 20Hz to 20kHz. Default is 1kHz.

Gain. Gain adjusts the gain value from -18 to 18dB, in .5dB steps. Default is 0dB.

Q, or Quality factor. Q, or Quality factor, selects the ratio of the center frequency

divided by the bandwidth. Q reflects an inverse relationship to the bandwidth, and

adjusts from .02:1 to 40:1 on the XAP 800.

Gate

The XAP 800 has unique gating parameters which control microphone activation.

The Gate button on the selected input in Inputs 1–8 window opens the Gate

configuration window where you can establish the gating parameters for the input.

Activation

There are three mic activation settings: Auto Gate, Manual On, and Manual Off.

• Auto Gate determines mic gating based on the input level and gating settings

for the gating group the input is assigned to. It contributes to and is affected

by all gating group settings such as NOM, chairman override, etc.

• Manual On activates a mic, provided it does not exceed max NOM

requirements of the gating group that the input is assigned to. It is included in

the NOM count.

• Manual Off deactivates a mic.

Chairman Override

Chairman Override provides gating priority for this mic input over any other mic input

within the same gating control (mixer) groups. When a mic with Chairman Override

enabled gates on, all mics which don’t have Chairman Override enabled will gate off.

Default is off.

Adaptive Ambient

Adaptive Ambient adjusts the ambient reference level as noise and room conditions

change. When adaptive ambient is on, the mic channel monitors the ambient noise

level on the input and adjusts the ambient level reference automatically. This means

that the gate threshold level automatically increases or decreases based on back-

ground noise. If Adaptive Ambient is turned off, the input will use the fixed ambient

level specified in the Ambient Level box as its gating reference. Default is on.

PA Adaptive Mode

PA Adaptive Mode uses loudspeaker audio level on a specified output as the new

ambient level when audio is present at the power amplifier. This prevents loudspeaker

audio from gating on the mic, while still allowing people in the room to gate on

microphones as they speak—provided that their voices are louder than the

loudspeaker audio. For example, you might decide to play background music from a

CD player during a presentation. PA Adapt Mode allows you to use the output routed

from the CD player as the ambient reference to prevent the CD player’s audio from

gating on microphones. An output must be specified as the PA Adaptive Reference

(this is the same as the AEC reference) for each mic in the system. Default is on.

Figure 3.34. Gate window

Page 45

System Configuration ~ Inputs and Outputs

Technical Services Group ~ 1-800-283-5936 (USA) ~ 1-801-974-3760

Gate Ratio

Gate Ratio specifies how much louder the audio level must be above the ambient

level before the channel gates on. The gate ratio range is from 0 to 50dB. Default is

15dB.

Hold Time

Hold Time determines how long the channel stays gated on after the audio is below

the threshold.The hold time range is from .1 to 8.0 seconds. Default is .3 seconds.

Off Attenuation

Off Attenuation sets the amount of level reduction applied to a channel when it is

gated off. The range is from 0 to 50dB. Default is 12dB.

Ambient Level

Ambient Level is available only if the Adaptive Ambient feature isn’t enabled. Use

Ambient Level if you want to specify a fixed reference point rather than one that

adjusts for background noise.The range is from -80 to 0dB. Default is Off.

Decay Rate

Decay Rate determines how fast a channel gates off after the hold time expires.

Default is Medium.

PA Adapt and AEC Reference

When using either the PA Adaptive mode (see page 38) or Acoustic Echo

Cancellation (see page 33), the output that carries this information, i.e. the reference

output, must be defined. Select the PA Adapt and AEC Reference from the drop-

down list. Any one of the 12 outputs, four expansion bus references, or four virtual

references can be selected.

If you select an

expansion bus reference

, the Define PA Adapt/AEC

Expansion Bus Ref window opens so you can identify which expansion bus output you

want to use as the PA reference. You can also open this window from the toolbar.

If you select a

virtual echo cancellation reference point

, the Virtual

Reference window will open. This window allows you to select which signals will be

used by the four virtual reference points.Virtual references are used when you need

to reference multiple outputs. The routing matrix portion of this window can not be

edited. You can also open this window from the G-Ware toolbar.

The PA Adapt Reference and AEC Reference are

the same for each channel. If you change the PA Adapt Reference for a channel, you will also make the same change to that channel’s AEC Reference.

Gating Group Select

In addition to specifying gating characteristics for each mic input, you can assign the

inputs to a gating group for greater flexibility and control. When inputs are assigned

to a gating group, the gating information from the inputs is used to control how the

entire mixer behaves.

The XAP 800 features four internal gating groups (Internal 1–4) and four

global gating groups across the expansion bus (Global A–D). Microphones can only

be used in one gating group at a time. If an input is not assigned to a gating group,

that mic’s gate properties are independent and have no effect on any other gating

group. When gating groups span two or more units (global gating groups), the

settings must be the same for each unit attached to the global gating group. Mic

inputs are routed to Global Group A by default.

To assign a gating group

•

Select the Internal or Global group the mic input will belong to or select

None.

To configure gating group settings

1. Click the Gating Control button on the toolbar. This opens the Gating

Controls window.

2. Select the Max # of Mics (default is 4).

This sets the maximum number of microphones that can be gated on at any

one time within a gating group. For internal groups, the maximum number of

mics can be from 1 to 8. For global groups the maximum number of mics

will vary depending on how many mic inputs are assigned to the gating group

(up to 64). You can also select All for the global groups—which means all

mics could gate on.

clear the selection to disable it. ClearOne recommends leaving this setting on.

This setting helps maintain maximum audio intelligibility by allowing only

one mic to gate on to a participant’s voice. 1st Mic Priority allows more

than one microphone to be activated at the same time—it simply restricts

mics from gating on to the same audio source. It does this by determining

the audio level received by all mics when the first mic is gated on. This audio

level is then used as the ambient level for the gating group. If this feature is

disabled, usually two or more microphones gate on when only one person

speaks.

4. Select last-mic operation from the Last Mic Mode list. There are two

options for Internal groups: Last On and Off. If you are configuring Global

groups, you can select from the mic inputs assigned to the Global group in

addition to Last On and Off.

Last On leaves the mic that was activated last full on until another mic input

is gated on.The Input setting allows you to select which mic input the

XAP 800 leaves on when all mics gate off. If Off is selected, all mics will

gate off when no audio is present. It is preferable in most applications to

leave a mic on so the remote participants don’t think they have lost their

audio connection. Off is typically only used when you are conferencing

multiple sites and need to reduce background noise.

5. Click the Gating Group label to change the group names.

Gain

The Coarse and Fine sliders on the selected input on the Inputs 1–8 window are used

to match the level settings for microphone inputs and to adjust input volume level.

• Set the Coarse gain to 55dB for a mic input, 25dB for active equipment that

requires an input between mic and line level, or 0dB for a line level input.

• Use the Fine gain slider to adjust input volume level.

You can also enter the

level directly in the 0.0dB box.

Min/Max limits

Use the yellow and blue upper and lower limit arrows on the Fine gain scale to create

minimum and maximum gain level limits.These limits only apply when using relative

gain commands; absolute gain commands can exceed the min and max limits.

Min/Max limits apply to all serially connected control devices and prevent users from

adjusting levels beyond the min/max levels, provided relative gain commands are

used.

Optimizing input gain structure

How you adjust an input’s gain directly affects sound quality.The optimal input gain

setting is one which is adjusted as high as possible above the noise floor without

introducing clipping. Clipping can cause distortion which can damage amplifiers and

loudspeakers.

To adjust the input level properly, place a signal on the input at the maximum

level it will generate. Adjust the input gain until the peak level of the input, as

shown on the Input meter, just begins to enter the red (clipping) zone, then reduce

the gain slightly until peaks no longer climb into the red zone.This setting will

ensure that the XAP 800 maximizes the signal-to-noise ratio without clipping the

signal.

Meters

There are four meters on each mic/line input to assist with setup and level control.

Select the meter check box to enable the meter. All input meters are peak-level.

Pre Gain

Pre Gain meter indicates the input’s level before gain adjustments. Meter range is from -85 to -35dB when 55dB gain is selected; -55 to -5dB when 25dB gain is selected; and -65 to 20dB when 0dB gain is selected.

Post Gain

Post Gain meter shows the input’s level after gain adjustments have been made. Meter range is from -30 to +20dB.

Post Processing

Post Processing meter indicates the level at the gating point after the signal has passed through input processing. It reflects the post-AGC signal. Meter range is from

-30 to +20dB.

Post Gating

Post Gating meter shows audio level after it has passed through the gating

parameters. Meter range is from -30 to +20dB.

Cmprs (compressor)

Cmprs opens the Compressor Setup window (see Figure 3.53). With the compressor

you can change the gain transfer characteristics of the signal path and control the

dynamics of a signal.

When the signal exceeds the threshold level, gain reduction occurs at the rate

specified by the reduction ratio. The attack time determines how aggressively the

compressor reacts to increases in level.The release time controls how aggressively

the compressor reacts to reductions in level. Select the Enable Compressor check

box to activate the compressor.

Group

Use the slider to assign this compressor to a compressor group.The default is

None

When you assign a compressor to a compressor group—such as a group of three,

configured for bass, midrange, and treble—the compressors will monitor each

other. When one compressor channel compresses, all compressors in the group

compress together. When configured properly, this results in a smooth audio

response throughout the frequency range, with no bass, midrange, or treble

dropouts. A given compressor group must be configured for a single XAP 800 unit;

a group cannot use compressors from multiple XAP 800 units.

Figure 3.53. Compressor Setup window

Compressors and compressor groups can be

established only within the XAP 800 unit being configured, i.e., they cannot be configured from a single point across multiple units.

Threshold Threshold determines the RMS level at which the compressor begins to

operate.The range is from -30 to +20dBu. Default is 0dBu.

Ratio Ratio changes the rate of compression applied to the input signal as the

signal exceeds the threshold level. The range is 1:1 to 1:20dB. Default is 1:1.

Attack Attack determines how quickly compression is enabled. It is calibrated in

milliseconds. The range is 0 to 100ms in .5ms steps. Default is 10ms.

Release Release determines how quickly compression is disabled.The range is

100ms to 2 seconds, in 5ms increments. Default is 500ms.

Filters

The Filter button on the selected Processing channel opens the Processing Filters

window. Here, you can configure all filters available in G-Ware: All Pass, Bessel,

Butterworth, CD Horn, High Pass, High Shelving, Linkwitz-Riley, Low Pass, Low

Shelving, Notch, and PEQ.

The frequency response and phase vs. frequency of the total transfer function

of all filters is displayed in the window. Each filter can be disabled without

affecting the filter settings. All filters can also be disabled using a single command.

By default, they are not enabled and the filter types are not defined. Below is a

description of each feature in the window.

Active Filter

The Active Filter displays the filter that is applied to the processing channel.

Type

Select the filter type from the Type list.

Note that the configurable filter parameters

displayed depend on the selected filter type.

You can use these parameters to

customize the filter, or use the mouse to click and drag the node on the graph to a

location that reflects the changes you want to make.

You can continue to add filters to the graph, and track their relationships to

each other to design a system with the sound characteristics necessary for good

audio.

Phase

Phase plots the phase response of the frequency response of the selected filter.

Bypass

Bypass All bypasses all filters.

Add Filter

Add Filter adds a filter to the graph.

Remove Filter

This removes the selected filter from the graph.

Table View

Table View toggles between the graph view and the table view.The table view allows

you to configure filters in a table format rather than on the graph, and provides an

easy way to check filter status.

Processing Channels

The Processing Channels section allows you to display the graphs of various

processing channels together, so you can view and easily modify filter and equalizer

settings throughout the frequency range. Click the respective letter to place a

processor in the graph. Click the Active processor you want to modify; it appears in

bold on the graph.

Technical Services Group ~ 1-800-283-5936 (USA) ~ 1-801-974-3760

Refer to the figure above. Note that as you create filters across several

processing channels, you can observe their crossover points and general shape of

the frequency response. In this case, several Linkwitz-Riley filters are being created

across three processing channels to establish a balanced frequency response from

low-frequency, midrange, and high-frequency transducers.

Delay

Click Delay to open the Delay configuration window. Delay calibrates the amount of

signal delay introduced, based on the length (the distance between the source and

audience) and temperature you enter.

For example, different speaker drivers within a speaker enclosure might be

located different distances from the listening area because of design constraints

within the box. You can set up to 500ms of delay.

Figure 3.55. Low/Mid/High Loudspeaker Driver configuration

Figure 3.56. Delay window

If you don’t want delay added to the signal, select the Bypass Delay box.

The Calculated Delay reading reflects any changes you make in the

distance and temperature fields.

System Configuration ~ Processing

Technical Services Group ~ 1-800-283-5936 (USA) ~ 1-801-974-3760

Introducing an appropriate amount of delay to the forward-mounted driver(s)

re-establishes the acoustical alignment necessary for proper sound imaging in a

room.The same principle of introducing delay applies to separate speaker

enclosures located various distances from the listening area.

Other types of delay to consider when establishing delay parameters are delays

which occur naturally as a result of processing operations within the

XAP 800. Propagation delay is an example. This delay is caused by operations such

as the conversion of the signal between analog and digital formats.

When you are finished making changes in the Delay window, click Close to

return to the Processor window.

Gain

Gain establishes the gain level for this channel. Select a level between -65 and 20dB.

If you select any level below -60dB, the signal will be muted. The

Process

meter,

when enabled, shows the signal level when a signal is present.

Min/Max limits

Use the yellow and blue upper and lower limit arrows on the Gain scale to create

minimum and maximum gain level limits.These limits only apply when using relative

gain commands; absolute gain commands can exceed the min and max limits.

Min/Max limits apply to all serially connected control devices and prevent users from

adjusting levels beyond the min/max levels, provided relative gain commands are

used.

Optimizing process gain structure

How you adjust the processing gain directly affects sound quality. The optimal gain

setting is one which is adjusted as high as possible above the noise floor without

introducing clipping. Clipping can cause distortion which can damage amplifiers and

loudspeakers.

To adjust the processing gain level properly, place a signal on the output at the

maximum level it will generate. Adjust the gain until the peak level of the input, as

shown on the Process meter, just begins to enter the red (clipping) zone, then

reduce the gain slightly until peaks no longer climb into the red zone.This setting

will ensure that the XAP 800 maximizes the signal-to-noise ratio without clipping

the signal.

CHAPTER 4: Advanced

Configuration

Presets

Overview

For many audio conferencing applications, a great deal of system flexibility is needed

to meet the challenges presented by changing meeting or conference room

requirements.These requirements may include changes in muting, audio sources,

room orientation, or room combining. And ideally, these changes are made

instantaneously—without interrupting or affecting any meetings in progress.

Using presets enables you to accommodate these changing room requirements

quickly and efficiently. When you create a preset, you are essentially creating a

single room configuration option. Presets can be programmed with a variety of

routing, level, gating, delay, filter, and EC reference settings to meet specific

application requirements.You can change every unit parameter or a select few

depending on your room needs. XAP 800 presets are unique in the sense that they

operate independently of other presets in the unit. When a preset is run, only the

selected inputs/outputs are changed—all other settings in other presets remain

unchanged and are not reset. This means you can change audio routing and

configuration settings in a room without affecting settings in other rooms (such as

gain).You can create up to 32 presets for the XAP 800.

Presets can be executed in a variety of different ways including the Execute

Preset utility in G-Ware, the front panel controls of the XAP 800, RS-232 external

control devices, RS-485 control devices (ClearOne Control Panel and XAP IR

Remote), logic in/out, and contact closure. You can also create macros which can

run multiple presets. These options give you tremendous flexibility when designing

your installations and will be described in more detail in this chapter.

Creating Presets

Presets are created in G-Ware using the Preset mode. To switch to Preset Mode,

click the Preset Mode button on the toolbar or the Preset Mode button on the Flow

Screen.The Preset Mode window (see Figure 4.2) consists of the Preset

Configuration Pane (left side of the window), the G-Ware menus and toolbar

(although most options are not available because they do not apply to presets), and

the Preset Matrix Screen.There is no Flow Screen in Preset Mode since all

configurable settings can be accessed from the Matrix Screen.

Figure 4.1. Preset Mode toolbar button

Presets are used only within the local

XAP 800 unit. However, if a preset is part of a macro, it can be activated on a networked XAP 800 unit.

Matrix Screen

The Matrix Screen in the Preset Mode is very similar to the Matrix Screen in

Configuration Mode. All Input, Output, and Processing windows can be accessed by

clicking on their respective buttons.You can also create custom labels by clicking on

the current labels.

The routing matrix is grayed out because no routing changes have been made.

When you click on the number or letter of an input, the row becomes active and

you can change the routing, gate status, and cross point attenuation. All

parameters for the selected input will be saved in the preset including routing.

Also, the parameters for any outputs with a cross point in the selected row will be

saved. Input rows that are not selected remain gray, or masked, and will not be

affected when the preset is run.

Preset Configuration pane

The Preset Configuration pane is used to create preset properties such as number,

name, and description as well as create custom preset controls, assign the preset to a

gating group, select macros, and configure virtual EC references.

Preset Selection. Use the Preset Selection list to assign a number to the preset

you are creating or to select an existing preset for editing.

Protected. Select the Protected check box to lock your preset. Locked presets are

indicated by a padlock icon.

Presets that are locked do not require the password

to be run. However, the password is required to make changes to the preset.

The

preset password is set in the Unit Properties window; see page 26.

A typical use for Preset Mask Control Status B is a room combining

application which uses automatic partitions with sensors or triggers which set the

pin to high (H) when the partition is closed and to low (L) when the partition is

open. For example, if pin 1 is connected to the first partition and Pin 3 is

Storage space

In a realistic preset configuration scenario, it is highly unlikely that you would reach

the storage capacity of the unit. In the event that you exceed the preset storage

space, G-Ware will alert you when you try to save the preset. You will be asked to

reduce the number of cross point changes or the number of macros in the preset. As

Running multiple presets simultaneously

To run multiple presets at the same time, you need to create macros (see page 63). A

macro is a series of commands which can be executed from G-Ware or by using any

external control device. Typically you will create a macro for each configuration or

group of presets you want to run at the same time. This ability to run multiple presets

is critical in applications such as room combining. However, not only do you need to

be able to run multiple presets simultaneously, you also need to be able to change

presets without affecting other presets.

In order for this to happen, the system needs to know which presets have been

run and shouldn’t be rerun and which ones are ready to run.You supply the system

with this information by setting the state (or flag) of the preset when creating the

command line in the macro. The three options are:

0 = to set the state to off

1 = to execute the preset and set the state to on

2 = to execute the preset and set the state to off

Figure 4.8. Execute Preset window

Figure 4.7. Execute Preset

toolbar button

It is also possible to assign

states to presets when

creating Remote Panel, serial, or GPIO control. However, unless you create macros, you will only be able to run one preset at a time.

Technical Services Group ~ 1-800-283-5936 (USA) ~ 1-801-974-3760

If a preset is flagged as “On,” nothing will happen when the preset is executed

again because the system knows it has already been run.This prevents any manual

adjustments that are made during the course of the meeting (gain, muting, etc.)

from being lost.

Room combining example

In the room combining scenario depicted in Figure 4.10, there are four possible room

configurations using six presets (P1–P6). In order to change configurations without

disturbing meetings in progress, a macro must be created for each configuration that

tells the system what to do with each of the six presets.

Figure 4.9. Assigning a state to a preset command in the Macro Editor

You can also create a macro to set all preset flags to 0 which ensures

all presets are ready to run again.

Technical Services Group ~ 1-800-283-5936 (USA) ~ 1-801-974-3760

The four macros (one for each configuration) are set up as follows:

When the room is in Configuration 1, running the Configuration 2 macro will change

the presets to the following states:

• P1 does not change because the flag is already set (1)

• P2 and P3 clear their states (0) so they can be run

• P4 runs and sets its state to on (1) which prevents other presets from

reruning it

• P5 and P6 clear their states (0) so they can be run

When the room is in Configuration 3, running the Configuration 1 macro will change

the presets to the following states:

• P1 and P2 run and set their state to on (1) which prevents other presets

from reruning them

• P3 does not change because the flag is already set (1)

• P4, P5, and P6 clear their states (0) so they can be run

next page.

Advanced Configuration ~ Macros

A macro is a series of commands which can be run from G-Ware, the front panel

controls, or by using any external control device. Macros streamline the operation of

the XAP 800, allowing you to make quick configuration changes and, as previously

discussed, making it possible to execute multiple presets simultaneously (see pages

60–62). Macros can also contain commands that are executed on other XAP units.

See pages 97–98 for a list of commands which can be used in macros.

The XAP 800 is designed to support up to 255 macros, with an average of

150 command lines each. In the unlikely event that you exceed G-Ware’s capacity,

you will be notified with a warning that indicates the command line at which

memory is exceeded.

Creating macros

There are two ways to create macros in G-Ware: the Macro Recorder, which

records your onscreen selections, and the Macro Editor, which allows you to

directly create command lines.The Macro Editor is also used to edit macros

created using the Macro Recorder.

To create a macro using Macro Recorder

1. Click the Macro Recorder button on the G-Ware toolbar. The Macro Record

window opens and the mode is changed to Macro on the status bar.

2. Select the macro number from the Macro to Record list, then click Start.

3. Make any routing and input/output configuration changes (such as gain

adjustments, mute, etc.) to be included in the macro. Make these changes the

same way you made changes in Configuration mode (see Chapter 3: System

Configuration for more information).

4. Click Stop in the Macro Record window in the upper right-hand corner of

the screen. This stops the macro recording and opens the Macro Editor

window. See page 65 for editing instructions.

Remote Modem Access

You can access the unit remotely through a modem connected to the serial port.To

enable this feature, configure the port for modem mode.

When in modem mode, the serial port will send an initialization string to the

modem upon entering the mode or upon power-up of the unit.You program the

initialization string in Site Properties window in G-Ware. Typical configurations you

set with the initialization string include setting a fixed baud rate for the unit and

setting up auto-answer parameters.

You must enter a password before you can control the system this way. The

default password is blank (a carriage return).You can change it to any

combination of letters and/or numbers up to 12 characters. It is not case-sensitive.

When you establish a valid serial connection with the unit in modem mode, the

unit will wait for a carriage return. When you have entered a carriage return, the

system will prompt you to enter the password. If there is no activity for five

minutes on the serial port while in modem mode, the unit will re-prompt for the

password.

Serial commands

Serial commands can be passed through the XAP 800 RS-232 port using Hyper

Terminal, touch panels, or other compatible remote control devices. To learn more

about serial commands, see Appendix E.

RS-232 Port

The modem password is created in the Unit

Properties window (see page 26) or by using the MPASS serial command (see page 117).

Appendices ~ Appendix C: Control Panel

The Volume Control Panel and Select Control Panel connect to either the Remote

Panel A or B connector of the PSR1212, XAP 800, or XAP 400 and works by

triggering the execution of programmed commands from the XAP/PSR unit. Each

button on the control panel is programmable to execute a single command or a

series of commands. Button function is programmed using G-Ware software (see the

XAP or PSR user manual). Each Control Panel fits inside a standard electrical wall

box and must be installed according to local electrical codes.

Connecting the Control Panel

1. Ensure you received a facia plate; a Control Panel assembly with mounting

bracket and two RS-485 Phoenix four-pin connectors; two connector

terminator blocks; a faceplate; two flat HD screws; two pan-head screws; and

an electrical wall box (shown in Figures C.5 and C.6). If any parts are

missing, please contact ClearOne.

2. Using DIP switches 1–4, assign a unique ID to the Control Panel.

Refer to

Figure C.2 for proper DIP switch settings. If you set an invalid address, all LEDs

on the Control Panel will illuminate.

3. Set DIP switch 8 to the on position if you are using just one Control Panel. If you

have more than one Control Panel daisy-chained to the same Remote Panel

connector, set

only

the

last

Control Panel’s DIP switch 8 to on. Switches 5-7 are

nonfunctional.

4. Turn off the XAP/PSR unit (unplug the unit).

5. Wire each end of a Cat. 5 cable to a connector terminator block. Use one

twisted wire pair for the center - and + connections (pins 2 and 3) and the

other twisted pair for the ground and +15V connections (pins 1 and 4). Failure

to correctly wire the connector can result in damage to the unit.

This equipment must be installed according to applicable local electrical

codes.

6. Connect one connector terminator block to the Remote Panel on the

XAP/PSR unit. Route the other end of the cable through the back of the

electrical wall box and connect the terminator block to the Control Panel.

7. To use a second Control Panel, connect it to the unused Remote Panel

connector on the XAP/PSR unit or the unused connector on the first

Control Panel. You can daisy-chain up to six Control Panels to each Remote

Panel connector. Total cable run depends on the number of Control Panels

used. The distance information in the table at left is based on Cat. 5 cable

with a nominal resistance of 27 per 1,000 feet (305 meters). All distances

refer to total cable runs from a single Remote Panel connector. For

information about extending beyond 800 feet (244 meters) total with six

Control Panels, call Technical Support at 1-800-283-5936.

8. As shown in Figures C.5 and C.6, use the supplied pan-head screws to install

the Control Panel PCB assembly to the electrical wall box.

9. To install the facia plate, position it over the conductive rubber switch pads

on the PCB assembly, as shown in Figures C.5 and C.6.

10. Mount the faceplate over the rubber switch pads, using the two flat HD

screws.

Appendices ~ Appendix E: Serial Commands

The XAP 800 accepts serial commands through the serial port or the expansion bus.The commands in this manual

pertain only to the XAP 800. RS-232 serial port protocol is 9,600, 19,200, 38,400 (default), or 57,600 baud; 8

bits, 1 stop bit, no parity.

Conventions

The following typographic conventions are used in this document to describe the different serial commands. Use the

Command structure section and the examples as a guide when creating your serial commands.

Convention Description

<X> Parameters enclosed in < > indicate a mandatory parameter.

[X] Parameters enclosed in [ ] indicate an optional parameter.

1-8 Parameters separated by a - indicate a range between the values.

4,7,9 Parameters separated by a , indicate a list of available values.

EREF

Words in uppercase bold indicate command text.

DEVICE Indicates the device type and device number on the expansion bus network. It is composed of a

device type character and a device number. The device type for the XAP 800 is always 5 and the

device ID will always be 0–7, or * (to select all 800 units).

Command structure

Commands can be either UPPER CASE or lower case. Also, extra spaces or tabs between arguments in text commands

are allowed. Return values are always in upper case. In order for a command to be recognized by the serial port, the

command must be terminated by a carriage return.

The structure of serial commands is as follows: #DEVICE

COMMAND

[X] [X]

# indicates the start of a command line

DEVICE represents the device type and device number

COMMAND

is the command text

[X] [X] represents any additional options in the order that they appear in the command descriptions that

Example

A command to disable automatic gain control for Mic 2 on a XAP 800 device “0” will have the command line:

#50 AGC 2 M 0. In this command line, 5=XAP 800, 0=unit 0, AGC=command, 2=channel, M=Mic Input group, 0=off

state. If a command calls for a “null” value, leave a blank in the command line. For example,“#50 AGC 2 M” will

return the current AGC state of Mic 2 on device 50.

Command responses will have a carriage return line feed. Example: #50 AGC 2 M O carriage return line feed.
