Master Section
Stereo Buss
There is a single, stereo 100mm fader to adjust the level of the stereo buss, with a large, illuminated, latching soft mute button. The left and right stereo buss outputs are available on the rear of the 5088 on transformer coupled XLR connectors.
Insert
An illuminated STEREO INSERT button engages the left and right insert sends and return, which are available on the rear of the 5088 on separate transformer coupled TRS connectors. The inserts are pre-fader/mute.
Stereo VU Meter
A pair of full size VU meters follows the Stereo Mix output.
Oscillator
An onboard oscillator outputs to a rear panel XLR connector and is activated by a front panel switch. There is a +/- 10dB trim control plus switch selection of six frequencies: 20Hz, 100Hz, 440Hz, 1kHz, 10kHz and 20kHz.
Speaker Selection
Three switches, designated A, B and C, route the monitor selection to one of three pairs of loudspeaker outputs on transformer coupled XLR connectors. A large, high quality pot controls the monitor output level, and an associated large, illuminated, latching DIM pushbutton reduces the monitor output level by 20dB.
Talkback Section
A front panel XLR connector provides a self level-adjusting microphone input for talkback, with phantom power (which may be disengaged at the internal jumper). The talkback master section includes mic input level control, a momentary push-to-talk button (non-illuminating), and destination switches that route the talkback mic signal to AUX 1/2, AUX 3/4, AUX 5/6, ALL AUXES, and the MAIN stereo buss (slate).
Monitor Source Selection
Five relay-interconnected switches provide monitor source selection. Sources include the stereo buss, solo buss, Aux 1/2 and EXT 1, EXT 2, and EXT 3, which each route the signals wired to an associated pair of transformer coupled XLR connectors on the rear panel to the selected monitor speakers. A MONO switch sums the selected stereo monitor signal for phase confirmation. The TO AUX 1/2 switch routes the selected source to the outputs of auxiliary sends 1 and 2.
