FRONT PANEL DESCRIPTION
1
POWER switch:
Depress the upper portion of this switch to turn the unit on (with power supply plugged in); depress the lower
portion to turn the unit off. Depressing the center portion of the switch causes acute indecision stress to the switch’s personality
profile, which in turn depresses it. To alleviate this condition, the switch must be “turned on”, so to speak.
2
Input LEVEL control:
is a rotary stereo attenuator that adjusts the amount of both Left and Right signals applied to the Input.
Its output is routed to the main summing amplifier for mixing with all other Inputs. The unity gain position of this control is
located at “7.5.”
3
Input OVERLOAD indicator:
glows red whenever the Input’s output exceeds a level 4 dB below clipping, letting you know it’s a
good idea to turn this Input down a bit.
4
Input BALANCE control:
In its center detent, Left and Right signals to each channel are allowed to pass at their original rela-
tive levels, therefore preserving the stereo image from instrument connected to the Inputs. When the control is moved vertically
toward the “L” position, the Right channel level is
decreased
while the Left channel level is
maintained
. The opposite occurs if the
control is moved from the detent down toward the “R”. When a mono input is used (no plug in the RIGHT Input jack), the BAL
control becomes a PAN control, panning the mono signal from the Left to Right channels.
5
Input SEND Level control:
determines the amount of
Post-Fade
stereo input is fed to the auxiliary buses. Each Input’s stereo
SEND is summed on this bus and is available at the respective LEFT and RIGHT LOOP SENDS on the rear of the mixer.
6
RETURN LEVEL control:
is a rotary stereo attenuator that controls the amount of Return which is to be added to the Main
Output. The unity gain position of this control is located at “7.5."
7
RETURN OVERLOAD indicator:
glows red whenever the return levels exceed a level of 4 dB below clipping.
8
RETURN BALANCE control:
is a vertical slider that controls the effect or source connected to the LOOP RETURN in the
same way the Input BALANCE controls work (see
4
above).
9
OUTPUT LEVEL control:
is a rotary stereo attenuator that controls the final signal Level at the main OUTPUT jacks. The
unity gain position of this control is located at “7.5".
0
OUTPUT OVERLOAD indicator:
glows red any time the output level exceeds 4 dB below clipping.
q
OUTPUT BALANCE control:
is
a vertical slider that operates in the same fashion as the BALANCE control described in item
4
above. It however, determines the relative levels of the LEFT and RIGHT main OUTPUTS only.
