OUTPUT GAIN Control:
Adjust this control to vary the amount of fixed gain (up to +20dB) in the 160A's output amplifier stage. The OUTPUT GAIN control does not interact with the threshold of compression.
DISPLAY Button and LED:
Depress this button to make the upper LED array display the INPUT LEVEL to the 160A. With the button out, the OUTPUT LEVEL is displayed. A pair of LEDs immediately above the DISPLAY button indicates the selected display.
INPUT/OUTPUT LEVEL and GAIN REDUCTION Displays:
The upper row of 19 LEDs displays either the INPUT or OUTPUT LEVEL, as selected with the DISPLAY button. This display is factory set so that 0dB is equivalent to +4dBu input or output level (1.23VRMS), but may be reset with the rear panel METER CALIBRATION trimmer. (See following pages.)
The lower row of 12 LEDs displays up to 40dB of GAIN REDUCTION (although the 160A is actually capable of deliv- ering up to 60dB of gain reduction). Note that fixed gain changes due to the OUTPUT GAIN control are not displayed by the GAIN REDUCTION LEDs but are reflected in the OUTPUT LEVEL display.
