SP 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, and 4-band fixed EQ
(80Hz, 300Hz, 2.7kHz, 10kHz) with an EQ In switch. Each input channel
>102 dB
shall also have: a FET controlled (10 millisecond ramp) mute switch with
> 96 dB
LED, sub-group assignment switches, a L/R assignment switch, a dedicat-
> 85 dB
ed mono assignment switch, a dynamic signal present LED and peak LED,
> 93 dB
a PFL switch, and a 100mm long throw fader. Each input channel shall
have eight auxiliary sends which shall be controlled via six knobs and
4kΩ balanced three switches.The aux sends shall have a pre/post fader switch for every
>10kΩ balanced
four sends. The aux sends shall be selectable pre or post fader.
140Ω balanced
The console shall be available in four or eight bus configurations. Each
group module shall have a ten-segment LED meter array. The effect return
section of each group module shall have a gain control, a two-band fixed
+ 4 to -62 dBu
EQ, sub-group assignment switches, a L/R assignment switch, a dedicated
+ 12 to -38 dBu
mono assignment switch, two aux send controls, a pan control, a level con-
+ 4 dBu
trol, a dynamic signal present LED and peak LED, and a PFL switch. The
- 2 dBu
remainder of the group module shall have a pan control, an FET controlled
+ 4 dBu
(10 millisecond ramp) mute switch with LED, assignment switches for:
+28 dBu
mono and L/R. A PFL switch, dynamic signal present LED and peak LED,
and a 100mm long throw fader shall also be provided on the group mod-
ule.
The master section shall be four modules in width and have the following
features: eight aux master controls with associated AFL switches, a
100mm long throw fader for each of the three master outputs and a com-
prehensive talkback system.
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 SP.
