Specifications - GT Console
The following text should be used when specifying a Century GT
in a bid or proposal.
The live sound console shall be constructed in a modular fashion and be
housed in a steel frame with molded plastic side panel/carrying handles.
The console shall be black with white labeling and utilize XLR lighting
device connectors. The console shall have an XLR talkback mic connector
and a headphone jack. These shall be located beneath the far right side of
<0.01%
the armrest.
All microphone inputs shall be electronically balanced and accessed via 3-
pin XLR connectors and have an EIN of -129 dBm. All line inputs shall be
-129 dBu
electronically balanced and accessed via 1/4" TRS jacks. The insert points
- 80 dBu
shall be via 1/4" TRS jacks.
- 80 dBu
Each input channel shall have: a +48 volt phantom power switch, a -15 dB
mic pad switch, a 80Hz high pass filter switch, a polarity reverse switch
and 4-band (LF-40-800Hz, LMF-100Hz-2kHz, HMF-400Hz-8kHz, HF-
>102 dB
1.5k-20kHz) sweepable EQ with peak/shelve switches on the high and low
> 96 dB
controls and an EQ In switch. Each input channel shall also have: a FET
> 85 dB
controlled (10 millisecond ramp) mute switch with LED, sub-group
> 93 dB
assignment switches, a L/R assignment switch, a dedicated mono assign-
ment switch, a dynamic signal present LED and peak LED, a PFL switch,
4kΩ balanced
4 scene mute switches (A-D), scene mute safe switch with LED, and a
>10kΩ balanced
100mm long throw fader.
140Ω balanced
Each input channel shall have eight auxiliary sends which shall be con-
trolled via six knobs and four switches. The aux sends shall have a
pre/post fader switch for every four sends. The aux sends shall be selec-
+ 4 to -62 dBu
table pre or post EQ and pre or post mute. There shall be an Aux 8 direct
+ 12 to -38 dBu
switch that shall allow the Aux 8 rotary knob to directly control the output
+ 4 dBu
of the 1/4" direct out TRS jack.
- 2 dBu
The console shall be available in four or eight bus configurations. Each
+ 4 dBu
group module shall have a ten-segment LED meter array. The effect return
+28 dBu
section of each group module shall have a gain control, a two-band fixed
EQ, sub-group assignment switches, a L/R assignment switch, a dedicated
mono assignment switch, two aux send controls, a pan control, a level con-
trol, a dynamic signal present LED and peak LED, and a PFL switch. The
remainder of the group module shall have a pan control, an FET controlled
(10 millisecond ramp) mute switch with LED, assignment switches for:
mono, L/R, Group XLR and matrix post. It shall also have a fader reverse
switch with LED. A PFL switch, dynamic signal present LED and peak
LED, 4 scene mute switches (A-D), scene mute safe switch with LED, and
a 100mm long throw fader shall also be provided on the group module.
The master section shall be four modules in width and have the following
features: an 11x2 matrix, eight aux master controls with associated AFL
switches, eight aux scene mute switches with LED, a 100mm long throw
fader for each of the three master outputs, a fully assignable comprehen-
sive talkback system, a talkback mic connection, a headphone jack, stereo
program input control, and five scene mute master switches each with
LED.
The power supply shall be housed in a 14 ga. steel chassis that shall occu-
py two 19" rack spaces. The power supply shall have the ability to be
daisy-chained to additional power supplies to provide a fail-safe operating
environment. Connection of two or more power supplies shall not require
additional interface hardware other than the provided cable.
The live sound console shall be: the Crest Audio Century GT.
