*Input Level Switch & Trim Control

In accordance with the input signal level, the combination of the Input Level Switch and Trim Control on each input module helps establish the input fader at an easy-operation position. When the Peak level indicator (the red LED) remains on or flashes occasionally, fully attenuate the trim control. If it still continues to flash, change the input level switch setting from "—60dB to —40dB" or "—40dB to —20dB", and readjust the trim control.

(Fig. 17)

The trim control changes the negative feedback volume, so that the gain of the head amp can

also be changed. THIS FUNCTIONS TO YIELD THE BEST COMBINATION OF MAXIMUM HEADROOM AND MINIMUM NOISE CHARACTERISTICS. The level indications (—60dBm, —40dBm and —20dBm) of the input level switch are nominal levels when the trim control is set at the "0" position.

Input level in conjunction with the Input Level switch and Trim control can be calculated as follows.
