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 the armrest. All microphone inputs shall be elec­tronically balanced and accessed via 3-pin XLR connectors and have an EIN of -129 dBu. All line inputs shall be electronically balanced and accessed via 1/4” TRS jacks. The insert points shall be via 1/4”
TRS jacks. 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-80Hz, LMF-100Hz-2kHz,
HMF-400Hz-8kHz, HF-10kHz) mid-sweepable EQ and an EQ In switch. Each input channel shall also have: a FET controlled (10 millisecond ramp) mute switch with LED, sub-group assignment switch­es, a L/R assignment switch, a dedicated mono assignment switch, a dynamic signal present LED and peak LED, 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 four switches. The aux sends shall have a pre/post fader switch for every four sends. The aux sends shall be selectable pre or post EQ and pre or
post mute. There shall be an Aux 8 direct switch that shall allow the Aux 8 rotary knob to directly control the output of the 1/4” direct out TRS jack.The console shall be available in four or eight bus

A PFL switch, dynamic signal present LED and peak 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: eight aux master controls with associated AFL switches, a 100mm
long throw fader for each of the three master outputs and a comprehensive talkback system. The standard power supply shall be housed in a 14 ga. steel chassis that shall occupy 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 Consoles Century TC.
