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.

How to use this manual
LED
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.
MIX SENDS are post-insert, post-eq, post-mute, post-fader

it's typical to make
Aux sends Post-fader

Console such as the XMonitor, all Mix Sends are
normally set for Post-Fader;
the Engineer uses the
Channel fader to control the

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.

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.

Output EQ features
The five-band output EQ consists of two semi-parametric bands and three full parametric
bands.The High and Low bands are shelving eq with frequency select and boost/cut controls.The three mid bands, High mid, Mid, and Low mid are full parametric with frequency,
bandwidth, and boost / cut controls. All bands offer a generous overlap of adjacent operating frequencies.
High frequency—HF
Frequency
Continuously sweepable between 2 kHz and 16 kHz.
Boost / Cut 15dB boost and cut. Shelving eq.
High mid—HM
Frequency
Continuously sweepable between 400 Hz and 8 kHz.
Q (Bandwidth) Continuously variable between 3 and .7
Boost / Cut 15dB boost and cut.
Mid frequencies—MF
Frequency
Continuously sweepable between 200 Hz and 4 kHz.

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.
HPF
High pass filter is on.The high pass filter cuts low frequencies to eliminate rumble
and feedback with minimal effect on program material.
HPF Frequency
Continuously variable between 20 Hz and 400 Hz.The high pass filter has a slope of
-12 dB per octave.
