Feature Overview
The SP / TC / GT features listed below
are common to all Century Series Consoles.
CENTURY SERIES
• SSM/PMI High quality preamplifiers on balanced microphone/line inputs and on all balanced outputs for uncompromised audio quality and reliability. All IC’s within the audio
path are socket mounted for easy upgrade or service.
• 48 Volt switchable phantom power on all microphone inputs.
• Optional transformers available on all microphone inputs and
on Group, Left/Right, Mono, and Matrix outputs.
• Full Bus assignment section on input and group sections
allow for independent assignment to the Mono Clean Bus in
addition to the Stereo and sub group sections of the console.
The Mono Clean Bus allows for any input or return signal to
be assigned to the Mono output without first having to pass
through a group.
• Dynamic Signal Present and multiple-sample-point peak indicator LED’s are used on all input sections of the console as
well as on all primary outputs.
• Mono/Stereo PFL and AFL system. When a stereo module is
used, the signal is monitored in stereo while mono modules are
monitored in mono. Selected outputs may be monitored in
mono or as stereo pairs.
• 8 Auxiliary Mix buses for use as effect and monitor sends.
Aux Send circuitry has front panel Pre/Post fader switching.
Pre fader signals have internal jumpers to select between a Pre
EQ or post EQ signal (Standard) source.
• Standard frame sizes include 24, 32, 40, 44 and 52 position,
with a 64 position frame available on special order. Consoles
may be ordered as 4 subgroup (8 Module Positions used
including Master Section) or 8 subgroup (12 Module Positions
used including Master Section) versions.
• Full facility return sections includes Gain Control to handle a
wide range of input levels, High and Low frequency EQ, Aux
Sends, full Bus assignment section and level, pan, PFL and
Mute controls.
• Mute system on input channels is designed to mute both preand post-fader signals including those Aux sends used as monitors. When muted, PFL circuitry, Peak and Dynamic Signal
Present LED indicators remain fully operational. This is a feature not available on many consoles at any cost.
• External power supply with optional shared load parallel
power supply for uncompromised reliability.
• The EQ section includes an EQ IN switch with LED and a
80Hz High Pass filter switch.
• Optional Matrix modules available.
• Optional Stereo Input modules available.
• Comprehensive Talkback section allows access to all primary
console outputs. Additional access provided to an external
location such as an on-stage monitor mixer system. External
signals can also be assigned into the talkback system including
Oscillator and Pink Noise source inputs.
• Left/Right summing switches to Aux 1-2 and Aux 3-4 allow
for simple setups of overdub mixes by allowing Left/Right signals to be blended with Auxiliary mixes when used in recording applications. In contracting applications, this feature allows
these Aux outputs to act as additional distribution amplifiers
for the Left/Right signals.
• Any frame size may be ordered short loaded for later expansion.
• Direct access to Group Mix Bus allows expander mixers to
be easily patched into the console.

Century Series Console Power Supply
Century Series Consoles use a separate rack-mountable power supply which provides the specific voltages used by each console.
Crest Audio’ Century Series makes use of two different power supplies. The model and frame size of your particular console
determines which of the two supplies should be used. SP, TC, and GT consoles use power supplies as follows: Consoles with
frame sizes of 24 or 32 modules use supply model XCVA04; consoles with frame sizes of 40, 44, 52, or 64 modules use supply
model XCVA06.

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 Century Series power supplies have certain electrical
requirements to operate properly. 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. Note the maximum current draw specifications
at right. Be sure that the circuit to which you connect the supply can handle the draw.
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 push the switch to the off position and then on again.
Ground Linking
Safety Considerations -
Each new power supply is shipped with the AC third wire
ground connected 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. Note that
when the console is disconnected from the power supply the
chassis ground connection to AC third wire ground is broken
and safety protection is lost. For 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 would otherwise create a hum-loop.

Twin Supply Operation
When twin supplies 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.
Console and Power Supply Grounding
Console chassis ground is electrically connected to audio
ground, pin 1 of XLR connectors and 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. This connection should never be disturbed. Hazardous
voltages exist inside the power supply which require the case
to be grounded. When rack-mounted, the power supply ground
may transfer to the rack case thru the front fixing screws,
though this connection is not reliable. When a console is configured within a complete sound system 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 electrical engineer.

Power Connections
The connections to and from the power supply vary depending
on your specific configuration. Before setting up the console,
always check to make sure the AC voltage marked on the
power supply agrees with the local supply. Always connect the
console to the power supply before switching on the power
supply. Do not run the power supply if it is not connected to
the console.
Multiple power supplies can be daisy-chained to provide failsafe protection in the event of a supply failure. When two or
more supplies are used, both power supplies run all the time. In
the event of supply failure, the remaining power supply(s) will
take over the entire load.
SP / TC / GT
NOTE: Although both of the multi-pin connectors on the back
of the power supply are labeled “POWER OUT”, it is necessary (and acceptable) to link two power supplies together as
shown in the diagram below.
ADDITIONAL NOTE: The multi-conductor cable used for
power supply-to-power supply connection is different than that
used for a conventional power supply-to-console connection,
and must be specified when the second power supply is
ordered.

SP Input Module
The SP input module is the most straightforward of the
Century Series. While it shares many features with more
complex input modules, the SP input module is simple in
design and operation.
LINE Switch
Selects between the Balanced XLR Microphone Input connector and the Balanced Line Input 1/4" TRS connector.
48V Phantom Power Switch
Turns on 48V Phantom Power, required by certain microphones for proper operation.
PAD Switch
Introduces a -15 dB attenuation to the mic input signal.
GAIN Control
Adjusts input gain for proper signal level.
80Hz High Pass Switch
Reduces all low frequency content at a 12db per octave rate
referenced to 80Hz (-3db point).
Four Band Fixed Equalizer
Controls the cut or gain of four fixed frequencies (10 kHz,
2.7kHz, 300Hz, 80Hz) within the input signal only when the
EQ IN switch is depressed.
EQ IN Switch
Inserts the EQ section into the input channel signal. An associated LED illuminates when the switch is down.
AUX Level 1•3 / 2•4
Adjusts audio level of a mix for use as a monitor or an effect
send. The signal source for this mix may be selected pre or
post fader by an associated switch.
AUX ASSIGNMENT 3•4 Switch
Selects the first two Aux level controls between the Aux 1•3
mix bus and the Aux 2•4 mix bus.
POST/PRE Switch
Selects the Aux 1•3 and Aux 2•4 signal sources between post
and pre fader positions.
AUX 5 - 8 Individual Level Controls
Adjusts audio level of a mix for use as a monitor or an effect
send. The signal source for these mixes may be selected pre
or post fader by an associated switch.
PRE/POST Switch
Selects the Aux 5 through 8 signal sources between pre and
post fader positions.
PAN CONTROL
Positions the channel image between the left (odd) and right
(even) channel assignment.

MONO Bus Assign Switch
Assigns the post-fader input signal directly to the Mono Clean
bus.
Bus Assign Switches (L/R, 1-8)
Assigns the post Pan Signals to the mix bus in odd/even pairs.
Pan controls assignment between these two mix buses with
extreme left pan assigning signal exclusively to the odd mix
bus and extreme right pan assigning signal exclusively to the
even mix bus. When the pan is in its center position, signal is
fed equally to the odd (left) and even (right) mix bus. When
used in stereo applications, the channel signal may be located
anywhere within the stereo image as controlled by the Pan control.
PFL Switch
Samples the channel’s signal pre-fader and allows for monitoring within the master section of the console. This signal is not
affected by the Mute Switch. When depressed, the signal level
can be seen on the Left/Right meters, and heard via the mixer’s
headphone or local monitor output. When this PFL Switch is
depressed, the channel PEAK LED indicator illuminates at a
lower intensity. When used as a status indicator of switch position, the Peak LED indicating circuit remains fully operational
by illuminating at a much higher intensity than its use as a PFL
status indicator.

preamplifier stage, after the EQ section, and after the fader.
This LED also serves as a PFL ON indicator, but at a much
lower intensity than when it is used to indicate clipping.
SIGNAL PRESENT LED
Constantly displays level activity of the input channel by varying in intensity.
100mm Fader
Used for control of all outputs of the channel except those Aux
output sections selected by switch to a pre fader position. (The
