X-MONITOR BLK DIA-REV1.2-7/27/01

Format

This manual uses a format that is intended to be easy to read, yet technical for those who need to
know all the details. For feature descriptions, this is done by devoting the left side of each page to 1)
an overall module picture, 2) a block diagram, and 3) a control closeup. These images all pertain to the
features and control descriptions on the right side of the page. Also, for certain features like the micro­processor system and the solo system that appear over and over again, references are made to sec­tions devoted to these features.

The intention is to make the manual easy to read while including all the technical details needed for
getting the most out of the X-Monitor console, a flexible and feature-rich addition to Crest Audio's grow­ing line of audio mixing console products.

Conventions

Control Icons

This manual uses little pictures, or icons to illustrate what the control descriptions are referring to. This
makes it possible to avoid redundant wording and makes the control descriptions clear.

Features

Phantom power +48V

48 volts DC is applied to pins 2 and 3 on the mic-input XLR connector. This option
is used with condenser microphones and active direct boxes that require an external DC
voltage (phantom power) in order to operate.

Pad

The mic-input signal is attenuated by 28dB to prevent some signals (e.g. kick drum or
lead vocal) from overloading the preamp stage.The pad is used to bring a hot mic-input sig­nal down to a controllable level.The pad is not functional when the LINE switch is depressed.

Line

The input preamp circuit is set up to accept a mic-level signal. This signal is brought in
via the XLR mic-input connector located on the rear panel.The 1/4" TRS input jack is dis­abled.

The input preamp circuit is set up to accept a line-level signal from either the XLR
mic-input connector or the 1/4" TRS input jack, both located on the rear panel.When a plug
is inserted into the 1/4" TRS input jack, the XLR mic-input connector is disabled.

Polarity reverse—ø

This feature is used for correcting or minimizing polarity and phase related errors. For
example, occasionally a balanced input connection is reverse-wired before it gets to the
mixing console. This can happen in microphones, or in snake line interfaces. By using the
polarity reverse feature, this type of error can be corrected.

Normal polarity
Polarity inverted

If the 48V phantom
power switch is
engaged, depressing this
Line switch disconnects
phantom power from the
mic input XLR.

+

When similar signals
from different chan­nels are combined, phase
cancellations can occur.

Reversing the polarity of an
input signal often corrects
such phasing errors.

+

The 48V switch should
not be engaged when
using standard (dynamic)
microphones, or other
sources that do not use
phantom power.

Features

Gain

The Input gain control range is closely related to the status of the PAD switch and the LINE
switch. In order to establish proper gain structure in the console, input gain settings must
be set correctly.

LINE—switch-up PA D —switch-up

12 to 72dB of gain can be added the mic-input signal.

The impedance at the input XLR is 4kΩ.

LINE—switch-up PA D —switch-down

-16 to 44dB of gain can be added to the mic-input signal.
The impedance at the input XLR is 4kΩ.

LINE—switch-down PA D —switch-up or -down

-10 to 45dB of gain can be added the line-input signal.
The impedance at the input XLR and input 1/4" TRS is 20kΩ.

High-pass filter—HPF

Proper use of the high-pass filter reduces or eliminates unwanted low frequencies without
substantially affecting the program material.Quite often such unwanted low frequencies are
included with in-coming mic- or line-input signals. For example, stage rumble or wind can
be picked up through vocal mics.The slope of the high-pass filter is -12dB per octave.

HPF

High-pass filter is on.

HPF—variable control

When the high-pass filter is on, this control selects a frequency between 20Hz and

400Hz as the point where attenuation begins.

If the channel peak
LED is illuminated,
first try lowering
the input gain control.

Only when this method is
unsuccessful should the pad
switch be engaged.

Input EQ features

Many audio signals coming into the console require some degree of corrective eq in order
to be part of a good sounding mix.The X-Monitor Input EQ allows the user to tailor the
incoming sound.

The input EQ consists of four bands:high, high-mid,low-mid, and low. The high band is shelv­ing, the low band offers shelving cut with a bell boost. The two mid-bands are bell shaped
with a Q of 2 and a generous overlap of adjacent operating frequencies. An independent,
variable high pass filter provides additional problem-solving flexibility.

High frequency—HF

Boost / Cut

15dB boost and cut at 12 kHz. Shelving eq.

High mid—HM

Boost / Cut

15dB boost and cut with a Q of 2.

Frequency Continuously sweepable between 400 Hz and 8 kHz.

Low mid—LM

Boost / Cut

15dB boost and cut with a Q of 2.

Frequency Continuously sweepable between 100 Hz and 2 kHz.

Low frequency—LF

Boost / Cut

15dB boost and cut at 100 Hz. Bell boost / Shelving cut.

Eq on

Equalizer is on. This switch is used to activate the EQ section and can be used to make
A/B comparisons between "flat" and eq'd signals.

Mix send features

The X-Monitor input strip has twelve Mix sends. Pre/Post fader switching is done in three
groups of four, 1 through 4, 5 through 8, and 9 through 12.These Mix sends are routed to
their corresponding outputs for creating up to twelve individual mono monitor mixes.They
can also be configured as stereo pairs,creating up to six stereo mixes.When configured for
stereo operation, the odd numbered pot becomes the stereo level control and the even
numbered pot becomes the pan control.Stereo configuration is done in stereo pairs (1&2,
3&4, 5&6...) and is selected in the Group output section (see Group output section for
more information.

Mix Sends 1-4, 5-8, 9-12

These knobs adjust the amount of signal sent to the twelve outputs.Unity gain occurs

at the the zero (1 - 2 o’clock) setting.

In mono mode, each control independently determines the send level for the respective
mix. When stereo mode is selected, the top (odd numbered) control sets signal level while
the bottom (even numbered) control pans the signal between odd and even group buses
(odd = left, even = right).

Mix PRE switches 1-4, 5-8, 9-12

The PRE switches determine the source for the three groups of four MIX sends.The sig­nal that these switches use for the PRE setting can be further defined by changing the posi­tion of a couple of internal jumpers. See

INTERNAL JUMPER OPTIONS.

for driving effects, and Pre­fader when used for moni­tors. With a Stage Monitor
Console such as the X­Monitor, all Mix Sends are
normally set for Post-Fader;
the Engineer uses the
Channel fader to control the
level to all mixes.

Level meter features

Level meter

Each input includes a five-segment LED meter for visually moni-

toring signal levels.This is essential for setting up and maintaining proper gain structure.

Peak indicator—PK

The input signal is monitored at several points throughout the channel.These points
are the mic preamp, the EQ stage and the fader stage. Overload at any of these stages will
cause the red peak-LED to light.
The channel gain should reduced if this occurs.

Signal level LEDs

These three LEDs light up at +8—yellow,0—green,and -6 dB—green.This level range

-6 to +8 is the optimum operating range. Compressed or relatively constant signals should
remain close to 0.

Signal present indicator—SIG

This green-LED varies in brightness in response to signal levels between -40 dB and ­6 dB.

Bus assignment features

In addition to providing full variable send capabilities in the Mix section,the X-Monitor also
offers audio grouping facilities for sending input signals to the output matrix section, and
directly to the A and B output masters for creating additional mixes. All assignments are
normally derived Post-fader(post-eq and post-mute).

Bus assignments 13, 14, 15 & 16

The input signal is assigned to Buses 13 thru 16 which feed Matrix 1 - 4, located above
the master control section.The feed to Buses 13-16 is normally Post-fader. All Bus 13-16
sends (from Inputs and Groups) can be globally switched to Pre-fader by using the 13-16
PRE switch, located in the Master section.

A Bus assignment

The Input signal is assigned to the main A output bus.This feed is always Post-fader.

B Bus assignment

The Input signal is assigned to the main B output bus.This feed is always Post-fader.

Input fader

The 100mm channel fader is the primary level control for all Post-fader signals being sent
to any of the console’s mix buses.The fader offers greater than 90dB of attenuation and up
to 10dB of boost . Normal operation is between -10 and 0.

Solo switch

Pressing this momentary switch will include (illuminate) or exclude (not-illuminated)
the channel from the consoles solo system. See Master Control Section for information on
Solo options.

Rear panel features

Direct out 1/4" TRS jack

The input channel's signal is available at this output jack.The D.O.signal is derived

Post-fader (post-eq and post-mute).This output jack is ground-compensated.

Insert points

Separate 1/4" TRS jacks provide the facilities for inserting an external signal processor into
the signal path of the input channel.

Insert send

This jack serves as an output for connection to the input of a signal processor.
The signal is derived after the mic preamp and HPF but before the eq section. Plugging a 1/4"
TRS plug into this jack does not break the signal flow of the channel.This output jack is
ground-compensated.

Insert return

The output of a signal processor is fed to this jack. It can accept a balanced or
unbalanced signal and is located pre-eq. Plugging a 1/4" TRS plug into this jack breaks the
normal signal flow of the channel.

Passive splitter features

The input of the X-Monitor includes a simple passive splitter for running input signals par­allel to another desk, typically a front-of-house console. In most cases this can eliminate the
need for a separate splitter box.

Pin 1 lift

When this button is depressed, the XLR Mic-In and Splitter-Out Pin-1 connection is
isolated from the chassis ground of the console.The Pin-1connection is maintained between
the two jacks, but is isolated from the mixer ground.
NOTE: When the Pin-1 Lift switch is depressed, the phantom power (+48V) from the X­Monitor won’t function for that XLR input. Phantom power needs the Pin-1 ground con-
nection for the return path for the +48 volts.

Balanced Input XLR connector—Bal In

This balanced female XLR (Pin 2 Hot) accepts a low-impedance microphone signal,or

a line-level signal, depending on position of the LINE switch on the front panel.

Splitter Out

This male XLR allows the channel input to be patched to another piece of audio
equipment, such as a front-of-house console. It is simply a parallel connection of whatever
is plugged into the Input XLR.
NOTE:All pins (1,2,3) are wired in parallel with the corresponding pins of the female XLR.
The Pin-1 Lift does NOT disconnect any of these parallel connections.

sends (from Inputs and Groups) can be globally switched to Pre-fader by using the 13-16
PRE switch, located in the Master section.

Bus A assignment

The Group signal is assigned to the main A output bus.This feed is always Post-fader.

Bus B assignment

The Group signal is assigned to the main B output bus.This feed is always Post-fader.

Group fader

The 100mm fader controls the level of the Group output and any Post-fader send.

Solo switch

Pressing this momentary switch will include (illuminate) or exclude (not-illuminated)
the group from the consoles solo system. See Master Control Section for information on
Solo options.

Output features

Output Connectors - Each Group

Group Out

Male XLR carries the post fader Group output signal. This output is designed to
drive output impedances greater than 600 ohms. The associated group metering follows
signal levels that appear on this output connector.

Insert Send & Return

Separate 1/4" TRS jacks are used for pre fader insert connectors. Signal is fed

full time to ground compensated insert send connector. When a connector is
plugged into the fully balanced 1/4" return jack, the internal signal path is broken, with the
external (processed) signal continuing its signal flow through the module. This pair of con­nectors is used to "patch" external signal processing such as 1/3 octave EQ into the mod­ule’s signal path.

Local return

1/4” TRS jack- Balanced (can accept balanced or unbalanced inputs). This input
feeds the group by way of the front panel "Local Return" controls. This may be used to
bring effects inputs or external mixes into the mix group output channel.

Common return (On Rear of Module 5-8)

A pair of 1/4” TRS jacks- Balanced (can accept balanced or unbalanced inputs).
Signals into these jacks are sent to the Common-return controls on the Master module.
Two separate inputs are provided to allow a common left and right signal to feed any of the
12 group mix output channels. Master On switches are provided as well as pre and post
fader Solo switching and master level controls. This section may be used to feed reference
or click tracks to any of the 12 main output mixes, or common ambience effects.

Master Module Summary

The MASTER module of X-Monitor serves multiple purpose.
The module contains the following sections:

• Matrix Output EQ and high pass filter

• Matrix Output mix

• Matrix Output control

• A and B Output control with 100mm faders

• Common Return master control

• Microprocessor Mute Controller

• Monitor control with 100mm fader

• Alternate and Headphone Outputs

• Talkback Control

• Solo Control

Matrix section

X-Monitor includes a unique matrix output system. Signal is assigned from Input and/or
Group modules into a mix bus section. These mix buses contains no front panel control or
output connectors, but rather are a source for the matrix system. Four output matrixes are
included. Each has separate control of master levels from mixes 13, 14, 15, and 16, as well as
an external input connector. Each matrix output includes level control, Solo switch and
microprocessor mute system.A five-band output EQ is available on each matrix output.

The matrix section may be used in a number of different ways:

Effects Sends - The most basic application of the matrix system is to feed effects devices from
individual input channels without any required re-patching. When used in this application,
matrix 1 would have mix 13 level control set to unity with all other level controls on matrix
1 (except output level) set fully counter-clockwise (or off). Matrix 2 would have mix 14 level
control set to unity with all other level controls on matrix 2 (except output level) set fully
counter-clockwise (or off). This same set up would be repeated with matrix 3 (mix 15) and
matrix 4 (mix16).

Output EQ features

The five-band output EQ consists of a high-freq shelving band followed by four semi-para­metric bell-shaped bands.The four bands have frequency and boost / cut controls. All bands
offer a generous overlap of adjacent operating frequencies.These Output EQs are normal­ly assigned to the Matrix Outputs.The first two (1 & 2) can be switched over to the Bus A
and Bus B Outputs with the EQ to A (B) switches.

Matrix Mix features

The Matrix section is fed from the internal Bus 13 thru 16 signals.These internal buses get
their signal from the Input and Groups via the Bus 13-16 assignment switches.The assign­ment to Buses 13-16 is normally post-fader, a master switch globally changes this to pre­fader. Each Matrix also has its own External input which can be mixed in with the Bus 13­16 signals.The External Input signal comes from the four 1/4” TRS jacks located on the rear
of the Master Module.

13- Bus 13 mix level into the Matrix.

14- Bus 14 mix level into the Matrix.

15- Bus 15 mix level into the Matrix.

16- Bus 16 mix level into the Matrix.

EXT IN- External Input mix level into the Matrix, from TRS jack on rear panel

MUTE- Micro-controllable mute control. See Micro-instructions for operation.

LEV- Master Level control for Matrix output.

SOLO- Allows monitoring of the Matrix signal in the Solo system.This feed follows

the master SOLO MODE switch. Pre-fader monitors the actual Matrix mix-bus, Post-Fader
monitors the Matrix signal after the Master Level and Mute controls.In the X-Monitor, the
Solo system makes a distinction between Inputs and Outputs.The Matrix Solo is treated as
an Output by the Solo system. See the Solo Section of the manual for details on the differ­ent Solo functions and modes.

Bus A & Bus B master controls

The Bus A and Bus B circuits are internal mix buses that can be fed from any Input or Group
module by using the A and B assignment switches located next to the fader on each mod­ule.The feed to these buses is always post-fader.These buses are similar to the Bus 13-16
internal buses except that:

1) The feed to Bus A & B is always post-fader. Feed to Bus 13-16 can be globally switched
to pre-fader.

2) The Bus A & B circuits have their own master faders with TB, Polarity, programmable
Mute and Solo switches. Bus 13-16 circuits only feed the matrix section.

SIG/ PK (Signal/Peak)

This dual-color LED shows the signal conditions within the Bus A (B) circuits.Varying
intensity GREEN shows signal present at the mix bus, RED indicates that signals are
approaching or have exceeded clip levels anywhere within the circuits.The Peak circuit mon­itors the mix bus and the pre and post fader signals.The LED will illuminate RED when any
signal comes within 3dB of clipping.

TLK TO (Talk To)

This switch (when depressed) allows the signal from the TalkBack section to be mixed

into the Bus A (B) circuits.

Ø (Polarity Reverse)

The polarity of the Bus A (B) output is reversed when this switch is depressed.

MUTE (Micro-Programmable)

This switch mutes the Bus A (B) outputs.The SAFE/PREV LED located directly below
the switch shows mico-mute status.See the Mico Section of the Owner’s manual for details
on its operation.

Fader

This 100mm fader controls the level of the post-fader output from Bus A (B)

SOLO

This switch is used to add/remove the Bus A (B) signal from the Solo Bus.The inter­nal LED (Yel) will illuminate whenever the Solo is active. In the X-Monitor, the Solo system
makes a distinction between Inputs and Outputs.The Bus A (B) solo is treated as an Output
by the Solo system. Both the pre-fader and post-fader signals can be monitored, See the
Solo Section of the manual for details on the different solo functions and modes.

Talkback features

Talkback control

The talkback section provides the facilities to take either an external input signal, or an internal­ly generated pink noise signal and route it to the consoles outputs.This is useful for making
announcements from the mix position and for performing system diagnostics when other signal
sources are not readily available.

Talkback Sources

The talkback control section can get its signal from three possible sources.

1) TB IN- An XLR jack located below the consoles armrest. Suited for Mic level inputs, Phantom
power is available on this jack via an internal jumper.

2) Pink noise generator,The internal noise generator can be selected with the PINK NOISE
switch. Depressing this switch both activates the internal noise generator and de-selects the TB
IN jack.Whichever of these two sources is selected is considered the “Internal” signal. NOTE: It
is ONLY this “Internal” signal that is fed to the External TB Out XLR jack when the TALK-
BACK OUT switch is depressed.

3) External TB IN- This XLR is located on the rear of the Master Module. Its line-level signal is
mixed with the “Internal” signal whenever EXT TB ON is depressed.The combination of this
Ext Input and the Internal source is what is fed to the modules when the Talkback is active.

Pink Noise switch

The talkback control section gets its internal source signal from the Talkback XLR mic

inputs.

The talkback control section gets its internal signal from the pink noise generator.

Talkback Level

This control sets the level of the talkback signal,whether it is from the external input or

consists of the internal pink noise generator.

TB ON - Talk back on

This "soft" switch activates the Talkback section. An internal RED LED will illuminate to indicate
that the TB is active.The Talkback section must be activate in order for any of its features to
work.

Tap switch once - This will toggle the Talkback section on and off.Tap once to turn it on,

when you're done tap it again to turn it off.

Press and hold - The switch will work as a momentary button if pressed and held for
more than two seconds.While the button is down, the Talkback section is activated.When you
release the button, the Talkback section shuts off.

EXT TB ON

When this switch is depressed, the signal from the rear-panel Ext TB In jack is mixed with
the internal TB signal.The TB Level pot and TALK ON switch control this input.

TALKBACK OUT

When this switch is depressed, the internal signal from the TB section is sent to the rear­panel Ext TB Out jack.The TB Level pot and TALK ON switch control this output.

Monitor, headphone & alt out features

Monitor, headphone & alt out control

The Monitor output normally follows the Solo system, any signals that are solo’d can
be heard in both the Headphone and Monitor outputs. A Mute button allows the
operator to silence the Monitor output, while an EXT MON IN switch permits the
operator to monitor an external source on the headphones.A pair of 1/4” TRS jacks
on the rear of the Master Module bring the Ext Input into the headphones.
Additionally, another output is provided (Alt Out) which also normally follows the
Solo system.An RTA or similar piece of monitoring gear can be driven from this out­put. For added versatility, the Bus A & B signals can alternately be fed to this output.

Solo features

Solo Control System

The X-Monitor is equipped with a powerful stereo solo system.Any input or output
can be monitored pre-level (PFL) or after level control (AFL), as desired.The system
may be set as additive (all channels selected on solo bus), or exclusive, so that only
one solo switch is active at a time ("last pressed"). Input Priority Mode is switch­selectable.This mode gives higher priority to the Inputs and automatically de-selects
any solo’d outputs when an Input is solo’d. When the Input is de-selected(or the
CLEAR sw is pressed), the previously active Output solo(s) return. Individual LEDs
indicate whether the solo system was triggered by an Input or Output. Any signal
being solo'd appears on the dedicated left and right solo meters on the meter bridge,
and is audible in the stereo headphone system and the Monitor outputs. Solo func­tions may be canceled by re-tapping any illuminated solo switch, or all solo switch­es may be simultaneously canceled using the Solo Clear switch.

Solo controls

SOLO ACTIVE (Solo status indicators)

Input - This Green LED illuminates whenever an Input channel is solo’d.

Output - This Red LED illuminates whenever an Output channel is solo’d.

INPUT PRIORITY (Solo I/O preference)

All solo signal sources are given equal weight. Input and Output solos can both

be monitored simultainiously.

Greater weight is given to Input Solos (Input channels,Common Returns, Local

Returns) than to Output solos.

LAST PRESSED (Solo Operating Mode)

Solo system is in “additive” mode. Pressing a solo switch will add that channel
to the solo bus, pressing again will remove it. As many channels as desired can be
combined and monitored. Input Priority has control over the mix (see above).

Solo system is in Last Pressed mode. Pressing any solo switch will clear (un­solo)any other solo’d. Only one source (the one last-pressed) can be monitored at
a time. Pressing the same solo switch again will remove it from the solo system.

POST FADER (Solo source select)

Pre-fader signals are monitored by the Solo system. Fader, Output level con­trols and Mutes do not affect the signal.

Post-fader signals are monitored.This point is after the Fader or Output level
control and also after the Mute switch.

SOLO ACTIVE / CLEAR (Solo tally / Master clear)

This momentary, illuminated switch provides two functions.

1. Solo active - When any input/output on the console is solo'd, this switch it lit up.

2. Clear - Pressing this switch will clear (shut off) any inputs/outputs on the console
that are solo'd.This is especially useful when the solo system is in Additive mode, to
clear multiple solos with one button press. When in Input Priority mode, the first
press will clear any Input solos present,the second press will clear any Output solos
that may return.

Ext TB In connector

This bal XLR connector allows an external signal to be fed into the Talkback sec­tion. From there, it can be routed to any of the outputs that are fed by the TB bus.
The Ext TB output from the FOH console can be patched into here to allow the

FOH engineer to communicate with the stage.

Ext TB Out connector

This bal XLR connector can feed the internal TB signal to the outside world. Used
in conjunction with the Ext TB In & Out of the FOH console, a two-way system can
be set up to allow the Monitoring position to communicate with the FOH position.

On Group Module 9-12 Rear Panel

Lamp Dim

This switch controls the intensity of the external little-lites plugged into the
rear of the meterbridge. In the UP position- full voltage is applied to the jacks. The
lamp-jacks are current limited to prevent accidents.

In the DOWN position- voltage is applied to the lamp-jacks thru dropping

resistors.

Meterbridge Connector

This 34-way socket connects to the meterbridge.The 14 meter signals(Groups 1-12, Solo
L-R) are carried to the meterbridge as audio signals, they are rectified to drive the meters
within the bridge. Power for the meter illumination (LED) as well as for the little-lites is also
provided.All power feeds are current-limited.

Midi IN and OUT

These jacks allow the microprocessor system to communicate with MIDI gear. See the sec­tion on the Microprocessor for more information. Standard MIDI cabeling should be used.

DC In

This 7-pin connector is used to connect the power supply DC cable to the console. ONLY
Crest approved power supplies should be used.A 25 ft DC cable is normally supplied with
the console. If two or more supplies are used for redundant operation,a separate 3 ft DC­Linking cable is used to tie power supplies together.

X-Monitor owner’s manual

microprocessor controlled muting

The Crest X-Series of Consoles* is equipped with a micro-controlled
Mute Controller which permits the user to set-up a series of Mute Scenes,
each controlling any combination of channels and outputs.These Scenes
can then be recalled, either singly or in combination, to allow the opera­tor to easily control the mutes during a performance.

The Mute Controller features 128 Sequenced Scenes (Patches) along with
8 Manual Mute Scenes. The 128 Patches can be stepped through using a
single button, or remotely activated by the use of MIDI patch-change com­mands.The Patches can be combined with the Manual Scenes to allow dif­ferent combinations of Channel mutes.

The following is a overview of the controls and indicators of the Mute
Controller and the Channels (see diagrams on previous page).The follow­ing information pertains to X-Eight consoles with Rev 1.12 firmware, and
X-Monitor consoles with Rev 1.00 firmware.

Channel Mute Sw (K) will add or remove a channel from the Safe Scene. If a channel
is included in the Safe Scene, it can’t be muted from a Mute Scene. This allows the
operator to remove a channel all Scenes without having to edit any of the Scenes
themselves. Pressing the Edit Safe switch again will exit back to normal operating
mode.

E)Single Scene

There are 9 mute sources available from the Mute Controller: the 8 Manual Mute
Scenes (H), and the Sequence Scene (G). Normally any or all of theses 9 sources can
be active at one time, which allows the operator to combine different mute patterns.
The Single Scene switch, when depressed, permits only 1 of the 9 sources to be active
at one time.

F)Micro Utility

This latching switch will put the system into Utility mode. The operator can then
access and view the various parameters and functions of the controller using the
Up/Down buttons (A) and the Display (B).

G)Sequence Scene

This switch activates the Sequenced Scene (Patch). The display (B) shows which of
the 128 possible Scenes are active.

H)Manual Mutes

These 8 switches activate the associated Manual Mute Scene. Additionally, these
switches, along with (G), select which Mute Scene is being edited when in Edit
Preview Mode.

Channel mute controls

J)Status LED

This bi-color LED, associated with each controlled Mute, shows the condition of that
mute. One of 5 possible states is possible:

1)Off- The channel is not controlled by the Mute Controller.

2)Steady Red- The channel is being muted by a Mute Scene.

3)Steady Green- The channel is in Safe Mode, can’t be muted by any Scene.

4)Blink Red- The system is in Edit Preview Mode and the channel is in the currently
selected Scene (only 1 Scene active at a time).

5)Blink Green- The system is in Edit Safe Mode and the channel is included in the Safe
Scene.

K)Mute Switch

This momentary switch toggles the Channel’s local mute and is also used to assign /
un-assign channels to Mute and Safe Scenes when in the Edit Modes.

L)Mute LED

This internal Red LED will illuminate whenever the channel is muted, either locally
or by a Mute Scene.

NOTE: If a channel is already locally muted when a relevant Mute Scene is activated, this LED
will remain lit. 2 sources are now telling the channel to mute; the Local Mute and the Mute
Scene. If the Mute Sw (K) is pressed once, the local mute will be cleared, but no apparent
change will occur. The Mute LED (L) will still be lit, and the Status LED (J) will still be steady
Red.At this point there is only one source telling the channel to mute; the Mute Scene. If the
Mute Scene is then disabled, the channel will un-mute because the Local Mute was previous­ly cleared.The user should be aware of this fact:The Local Mutes can toggle invisibly behind
a Mute Scene. For an even number of presses on the Mute Sw (K), the Local Mute will return
to its original state, an odd number of presses will change the Local Mute to its opposite state.
Each press of this switch increments the Sequenced Mutes by one, the display (B) will reflect
this. Also used to activate the displayed Scene when an Up/Down (A) button was used to
scroll to a new Scene. In this case, an "*" will be displayed as the first character in the display
to indicate that the displayed number is not currently the active Scene. Pressing GO will put
that displayed Scene into place and clear the "*" from the display.

NOTE:All of the above actions will take place, but the displayed Sequenced Scene will not be
active (mutes not enabled) unless the Sequence Scene switch (G) is lit. Each press of these
switches increments or decriments the Patch Display (B). Holding either button down will
allow quickly scrolling up or down.The buttons are also used to select the parameters and
settings of the system while in Utility mode.

Mute scenes

There are nine possible Scene sources: Manual Mute Scenes 1 thru 8, and the
Sequence Scene. The Sequence Scene button (G) is the enable switch for the 128
possible Sequenced Scenes.The 8 Manual Mutes are totally independent of the 128
Sequenced Scenes, giving the system a total of 136 possible mute patterns. Each of
the 136 patterns can consist of any combination of Channel and Output mutes, all of
the nine possible sources can be combined to create additional patterns.

Creating a Mute Scene (or Editing an existing one):

1) Press the Edit Preview button (C), it will begin to blink, indicating that the system
is in Edit Preview Mode.

2) Select a Scene to Edit: The system will automatically choose a Scene to edit,
depending on the status of the system when Edit Preview was selected. If the system
was in Single Scene Mode (switch E depressed), the Mute Scene that was currently
active will be selected to edit. If the system was in Multiple Scene Mode (switch E
not depressed), the Sequence Scene will be automatically selected for editing. If a dif­ferent Scene than the default is to be edited, that scene should now be chosen by
pressing 1 of the 9 possible Mute Scene buttons (G & H), it will illuminate to show
its selection. Only one scene can be selected for editing, the condition of the Single
Scene button (E) has no effect in Edit mode.

3) If Sequence Scene is selected: If Sequence Scene (G) was selected, then the
Up/Down (A) buttons should be used to select the desired Sequenced Scene (Patch)
to be edited.The Display (B) will indicate which of the 128 possible patches is being
worked on. Note: When returning to Normal Mode, the system will revert back to
the Patch that was in place before entering Edit Mode.

4) Assign channels to the Scene: Any channels currently assigned to the Scene being
edited will have their Status LEDs (J) blinking Red. Pressing the associated Mute Sw
(K) will assign / de-assign that channel to the Scene.

5) Clearing a Mute Scene: If you wish to clear all assigned channels from a Scene,
press and hold the Edit Safe (D) button.After a brief delay, the display will change to
CLR?; continue to hold the button down until the display shows CLRD.All channels
assigned to that Scene will be de-assigned and you can start fresh.

6) Saving your edit: Once you have a Scene configured the way you want it, either
press the blinking Edit Preview (C) button to exit Edit Mode and return to Normal
Mode, or select another Scene to edit by pressing its associated switch (H), or, if
Sequence Scene was selected, press the Up/Down (A) keys to select a new Patch to
edit. There is no STORE button to press, the changes take place immediately while
editing, and the Scene is saved automatically when a new Scene is selected or upon
exiting Edit mode. NOTE:This immediate change will be most apparent when editing
a scene that is currently the active scene (the Mute Scene that was ON when you
entered Edit mode).The Mute LED (L) will change along with the Status LED (J) as a
channel is added or removed from the scene during editing.

Copying a mute scene

Mute Scenes can be copied from a Sequenced Scene (Patch) to a Manual Mute Scene. Manual
Mutes cannot be copied to Sequenced Scenes or to each other. To copy a Sequenced Scene
into a Manual Mute Scene, follow the steps outlined below.

1) Press the Edit Preview button (C), it will begin to blink, indicating that the system
is in Edit Preview Mode.

2) Select Sequenced Scenes by pressing the Sequence Scene (G) button; it will illu­minate.

3) Scroll to the Scene to be copied using the Up/Down (A) keys to change the
Display (B).

4) Hold down the Sequence Scene button.The display will show "Cpy?".

5) Still holding down the Sequence Scene button (G), now also press the desired
Manual Mute switch (H). The display will show "Copy", and the Sequenced Scene
Mute pattern is copied to the target Manual Mute, over-writing whatever pattern may
have originally been there.

6) You can now select the newly created Manual Mute Scene for editing by pressing
its select switch (G). The copied Mute pattern will be there, you can use that as a
starting point for your edits.

7) Exit back to Normal mode when you’re done by pressing Edit Preview (C) again.

NOTE:You can use this copy feature as a way to "Back-up" your Manual Mute Scenes,
even though you can’t copy from Manual Mutes to any other Mutes. Instead, use the
highest numbered Patches (120 to 127) to create the original versions of your
Manual Mute Scenes.Then use the copy function to transfer those patterns into the
Manual Mutes.You can always go back to the originals (120 to 127) and re-load (copy)
them into the Manual Mutes whenever needed.You can also use Patch 128 as an All
Mute memory. Program it with all channels muted, you can then copy it to a Manual
Mute when you need to start a Scene with all channels muted instead of all channels
un-muted ( you already have a way to start a Scene with all channels un-muted, you
can hold down the Edit Safe button to clear all mutes in a Scene when editing).

The Safe Scene

There may be occasions when a channel needs to be made "Safe" from all programmed
mutes.This may occur during a show when an on-stage microphone needs to be used as an
announce mic, or a switch-over has to be made to a backup channel due to some technical
difficulty.The Safe Scene allows a channel to be removed from the control of all Mute Scenes
without having to edit any of the scenes. Once a channel is assigned to the Safe Scene, it will
ignore all Mute Scene commands.The Mute Scenes themselves are not altered, it’s only the
channel’s response that has been changed.This allows temporary changes to be made to a
show, due to nightly needs, without having to go in and edit the programmed scenes.You’ll
probably need the original scenes, as is, the next time the show is performed. NOTE: The
Local mute command is not affected by this Safe, the Local mute is always effective.

The Safe Scene is always active, if a channel is assigned to the Safe Scene, it will ignore any
mute commands from a Mute Scene.The Status LED (J) of a channel will be a steady Green
color if a channel is Safe.
Editing the Safe Scene:

1) Enter Edit Safe Mode: Press the Edit Safe button (D), it will begin to blink, indi­cating that the system is in Edit Safe Mode.

2) Select a channel to safe: Pressing the Mute Sw (K) of a channel will assign/de­assign a channel to the Safe Scene.The status LED (J) of any channel assigned to the
Safe Scene will blink Green. If a channel is currently muted because of a Mute Scene,
assigning it to the Safe Scene will immediately un-mute it.

3) Clearing the Safe Scene: If you wish to clear all assigned channels from the
Safe Scene, press and hold the Edit Preview (C) button. After a second or two, the
display will change to CLR?. Continue to hold the button down until the display
shows CLRD.All channels assigned to the Safe Scene will be de-assigned and you can
start fresh.

4) Exit Edit Safe Mode: Press the blinking Edit Safe button (D) again. It will stop
blinking and the system will return to Normal mode.Any blinking Green status LEDs
will turn to steady Green indicating that the channel is in Safe mode. If a channel was
previously being muted by only a Mute Scene (status LED was steady Red), but is now
"Safe", the status LED will show steady Green and the Mute LED (L) will be off. If the
channel was being muted by a Local mute, it will remain muted.The Safe Scene does
not affect Local Mutes.

NOTE: Assigning a channel to the Safe Scene can be done quickly if an emergency
arises and a programmed channel has to be un-muted. It’s a simple 3 step process:

1) Press the Edit Safe Sw to enter Edit Safe mode

2) Press the Mute Sw of the desired channel- The channel will un-muted at this point.

3) Press the Edit Safe Sw again to return to Normal mode

Utilities

The Mute Controller has a number of parameters that the user can change.A Utility Mode
is provided for accessing these settings.The following is a current list of parameters, along
with their default and other possible settings.The default setting is shown UNDERLINED.An
explanation follows on how to review or change the different settings.

Display Meaning Settings

uP Micro Processor ON or OFF

Determines whether the Mute System is ON or OFF.When OFF, the entire Mute Scene sys­tem is disabled, only the Local mutes will operate. This setting can be used if "Traditional"
console operation is desired (i.e. No programmed scenes are wanted).

M Ch MIDI Channel 01 to 16

Sets the MIDI channel that the Controller uses to communicate to the MIDI world.The Mute
Controller can send and receive MIDI Program changes, MIDI dumps etc. It does so on this
channel.

Lock Edit Lock OFF or ON

If set to ON, prevents any changes to be made to any Mute Scene. If Edit Preview is pressed
when LOCK is ON, "Lock" is displayed and the system will not enter Edit Mode.

Dmp? MIDI Dump

When activated, the contents of all the Mute Scenes are transmitted via the MIDI Out jack
using SysEx protocol.A librarian or archiving MIDI program can be used to store the Mute
settings externally. Note: Loading of external data via SysEx command is always active.

Base MIDI Base 01 or 00

There are 128 possible MIDI numbers. Do you want to start counting at 01 and count up to
128, or start at 00 and count up to 127 ? Different MIDI devices do it either way.You get to
choose.

Ext External Ctrl OFF or ON

Normally, the Mute System uses its internal Mute Scenes to control the Console mutes.
Alternately, MIDI Note Commands can be used to control the channel mutes directly. When
Ext is ON, the Display(B) will show "Ext", and the normal Mute Scenes will be disabled. The
Controller will now respond only to externally received Note On/Off commands (via MIDI
In jack).

Pgm Program Chg ON or OFF

The Mute Controller normally sends a MIDI Program change command every time the
RECALL (I) button is pressed, corresponding to the Patch number shown in the Display.Also,
if a MIDI Pgm Chg is received, the Controller will respond by recalling the Patch Mute match­ing that Pgm Chng. Setting Pgm to OFF disables the sending and receiving of MIDI Pgm
Changes.

Changing and reviewing the utility changes

The Utility settings can be accessed by entering Utility Mode. Once there, the different para­meters can be changed to suit user’s preferences.The changes stay in effect until they are
again modified by the user, or a System Reset is performed (detailed later) which changes
them all back to their default settings.

Utility Mode:

1) Enter Utility Mode: Press the Micro Utility button (F), it is a latching switch,

and the system will stay in Utility Mode while this button is depressed.The Display
(B) now shows the first Parameter - " uP " of the Parameter List.

2) Select a Parameter to edit: Use the Up/Down keys (A) to scroll thru the list
of available Parameters.

3) View the current Setting: Press the GO (I) button.The Display will change
from showing the Parameter to showing the Parameters current setting.

4) Changing the setting: While the Display is showing Parameter Settings (not the
Parameter itself), the Up/Down keys will scroll thru the list of possible settings for
that Parameter. Use the keys to select the new setting and press the GO button
again.The Display will briefly show " **** ", the displayed setting will be activated and
the Display will go back to showing the Parameter. Note: The only way to get back
to showing the Parameter is to press the GO button, so even if no change is desired,
the GO button must be pressed. Make sure the display is showing the desired
setting when you press GO. You are now back at Step 2, and can continue to
select and change Parameters.

5) Exit Utility Mode: Once you’re done, press and release the Micro Utility (F) key,
the Mute System returns to Normal Mode with the new settings in place.

power supply usage

Console and power supply grounding

Console chassis ground is electrically connected to: the audio ground, pin-1 of XLR connectors,
the sleeves of

1/4” sockets, and to the terminal CONSOLE GROUND at the rear of the power supply.

The AC third-wire connection in the power supply cable connects the metal chassis of the
power supply to safety ground.

Rack-mounting—the power supply ground may transfer to the rack case through the front fix­ing screws, though this connection is not reliable.

Sound system use—the grounding requirements may call for the ground link to be disconnect­ed.This is permissible only when an alternative ground path has been provided. If in doubt seek
the advice of an experienced electrician.

Redundant power supplies

The console power supply can be considered the single most important component in an entire
sound system. If a power amplifier, a signal processor or a console input goes down in the mid­dle of a show, the show can still go on.But if the console loses its power supply,the show is over.
For this reason, it is always good practice to incorporate redundant power supplies for mixing
consoles used in professional sound reinforcement applications.

This should be considered a high priority even when using a very reliable power supply. In even
the most carefully designed sound systems,each component runs the risk of failure at sometime
or another.

Crest Audio uses two methods for attaching redundant power supplies to consoles. In both
methods, the two (or more) power supplies should be kept on while the console is in use to
insure a smooth transition in the event that one shuts off.

If one power supply drops in voltage or shuts off completely, the other unit takes over without
any interruptions or audible glitches.As an added precaution, the two (or more) power supplies
can be fed by separate AC lines.This will guarantee that the console does not shut off if one of
the AC lines goes down.

Multiple power supplies in-series

Crest Audio X-Series consoles use this method for backup. Since each power supply includes
voltage switching circuitry, more than two units can be hooked up in series. A DC-Link cable
ties the power supplies together. Normally two supplies are used for redundant (fail-safe) oper­ation, but there is no real limit to the number of supplies that can be used.A daisy-chain can be
constructed using DC-Link cables to tie each supply to the next.At the end of the chain, the
last power supply uses the normal DC power cable to tie the entire power supply chain to the
Console.

Power supply usage

Supply identification

The type of power supply can be identified by the model number shown on the back of the
chassis and panel label.

Power requirements

The X-Series power supplies have certain electrical requirements for proper operation.If possible
the power supply should be connected to a dedicated circuit. Should any other appliance on the
same circuit draw enough current to overload the circuit, the breaker or fuse will trip causing loss
of power to the console.

The power switch on the supply front panel is also a circuit breaker; there is no power fuse.
Should the supply ever shut down, or trip at start up, simply toggle the switch to the off posi­tion and then push on again.

Ground linking

SAFETY CONSIDERATIONS—each new power supply is shipped with the AC third-wire ground con-

nected to the console chassis ground.The connection is made at the rear of the power supply
unit.This is necessary for safety reasons so that exposed metal parts are grounded. In the event
of a live conductor making contact with the console chassis or the power supply chassis then the
current will flow to ground without a safety hazard arising.

Uninterruptible grounding—in a fixed installation for example,make a connection directly to the
console chassis from the safety ground. Disconnect the ground link on the rear of the power
supply.This disconnects console ground from power supply AC third-wire ground which could
possibly create a hum-loop.

Twin-supply operation

When twin-supplies (or more) are in use for automatic back-up, then the ground links on both
supplies should be fitted.

In a situation where the safety ground to the console chassis has been connected and the ground
path via the power supply is causing a hum-loop, then disconnect the ground links on both
power supplies.

Power supply Controls

Feature identification

The various switches, connectors, indicators and controls of the X-Series power supply are
called out and described below.

Front Panel

A) Power switch. Used to turn the unit ON and OFF, it also acts as the circuit breaker for the

supply. In the case of internal faults or overloads, the breaker will automatically switch to the
OFF position.

B) Exhaust Vents.There is an internal fan mounted on the rear of the unit.The fan brings cool air

in from the back and exhausts it through these front vents.To insure proper cooling,both these
vents and the rear fan should be kept clear of any obstructions.

C) DC Indicator LEDs.These four green LEDs show the status of the DC outputs of the supply.

When illuminated, they indicate that the associated DC voltage is OK.

D) DC Output Connectors.These two parallel-wired connectors are used to connect the DC

output of the supply to the Console, either connector can be used.The spare connector is
used when a backup supply is also connected to the Console. For power supply to Console
connection, use the normal 25ft male-to-female cable.When attaching a spare supply, use the
4ft male-to-male DC-Link cable.

E) Ground Link.This terminal block makes both the Console Ground and PS Chassis Ground

available for connection.Normally a shorting-link is provided that ties the two grounds togeth­er. The Console Gnd is the Audio Ground (0 volts) of the power supply, the Chassis Gnd is
the case of the PS chassis. Certain situations may arise where a hum-loop may occur due to
multiple ground paths being present in a system.Removing this shorting-link may solve a hum
problem by breaking one of those paths.NOTE:Removing this shorting-link does NOT lift the
PS chassis from the AC third-wire ground.The chassis is ALWAYS tied to the third-wire ground
of the AC inlet connector and is there for AC shock protection. If an internal fault occurs in
the power supply that puts dangerous voltage on the chassis, this third-wire connection is
there to shunt that potentially dangerous voltage to AC ground.That safety connection should
never be tampered with.

F) Cooling Fan / Filter. A quiet constant-speed fan draws cooling air in through the external fan-

filter and exhausts the heated air through the front panel vents.The filter should be cleaned
whenever dust buildup is observed.The snap-off cover can be removed to gain access to the
filter.The filter (foam) can be cleaned by rinsing with plain water or by vacuuming.

G) AC Inlet.This standard 15-amp IEC connector is used to bring the local AC mains voltage into

the power supply.The power supply is designed to work with any standard voltage used world­wide; 100V to 240V 50/60 Hz.
