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 userdefinable 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.

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 L AN) 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.

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

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 threeterminal 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 ter minator 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.

Figure 2.4. E-bus connection diagram

Networking Units

ClearOne recommends that the first unit in your E-bus network be a XAP 400 or

XAP 800 rather than a XAP TH2.

✍

RS-232 system-wide control can be provided by any unit in the network.

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.

Baud Rate

This parameter allows you to set the XAP 800’s baud rate to 9.6kbps, 19.2kbps,

38.4kbps, or 57.6kbps. Default is 38.4kbps. Select the baud rate you want to use, then press Enter.

Installation ~ LCD Programming

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

ClearOne recommends that you leave Flow Control enabled.

✍

The modem initialization string can only be set via

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.

Clear Password

This parameter allows you to erase the serial port (modem) password in case it has been forgotten. Select Yes to keep the current password or No to erase it. Press Enter to enable your selection.

Meter menu

There are six submenus under the Meter menu: Inputs, Outputs, Processing, ERL, ERLE, and Default Meter. The meter selection determines what is shown on the front panel peak-level LED display.
