Power Switch
(Front Panel; #10)
The POWER switch applies power to the unit. Above the switch is an LED
light which will illuminate RED when power is on.
Individual Volume
Controls
(Front Panel; #1– #4)
Each input is controlled by an individual volume control.
Master Volume Control
(Front Panel; #8)
The overall volume is controlled by the MASTER volume control.
Lo-Cut Filter
(Rear Panel; #5)
The Lo-Cut filter on the rear panel provides low-frequency attenuation on
the microphone inputs. This helps reduce mic breath pop, wind noise, and
rumble.
Contour Switch
(Front Panel; #5)
This switch enables or bypasses the variable loudness contour. This
feature only effects the AUX inputs.
This feature is designed to improve richness of sound by restoring the
high and low frequencies that the ear is insensitive to at low volume
levels. The effect diminishes as volume is increased.
Audio Enhancement
(Front Panel; #9 / Rear Panel; #16)
The front panel Audio Enhancement switch enables or bypasses the Audio
Enhancement feature. This feature effects all inputs when enabled.
By regenerating the upper harmonics, this audio enhancement system
recreates the presence and realism that is lost in the audio amplification
process. This results in increased presence and clarity, increased intelli-
gibility, greater perceived loudness (without using extra power), and
reduced listener fatigue.
The rear panel AE adjustment controls the mix of the Audio Enhancement
effect with the audio signal. Counterclockwise rotation of the control
minimizes the Audio Enhancement effect. Clockwise rotation of the control
maximizes the Audio Enhancement effect.
