Manual-2
MID/HIGH Frequency control
This 31-position selector sets the crossover frequency
between the Mid and High frequency Outputs in both
channels. Consult the manufacturer of the drivers or
cabinets for the correct setting.
MID & HIGH LEVEL controls
This controls the level of signal going to the HIGH OUTPUT jacks.
Unity gain is reached at the “0 dB” mark with the INPUT LEVEL set to
“10”. Refer to Operating Instructions on page Manual-4.
INPUT LEVEL control and indicators
This controls the overall level without altering the
relative settings of the Low, Mid and High frequency
Outputs. Input gain is +6 dB at “10”. With signal
applied, set this control so the +4 dBu LED lights oc-
casionally, indicating sufficient signal. Flashing of the
OL (overload) LED during peaks can be avoided by
turning the INPUT LEVEL down.
MONO SUB LEVEL and LOW LEVEL controls
These control the signal levels going to the respective
OUTPUT jacks. Unity gain is reached at the “0 dB”
mark with the INPUT LEVEL set to “10”. The LOW
LEVEL control does not affect the MONO SUB
LEVEL— they are independent. Refer to Operating
Instructions on page Manual-4.
LOW/MID Frequency control
This 31-position selector sets the crossover frequency
between the Low and MId frequency Outputs in both
channels. Consult the manufacturer of the drivers or
cabinets for the correct setting.
