5. When moving this equipment, it should be placed in its original carton
and packaging. This will reduce the risk of damage during transit.
6. DO NOT EXPOSE THIS UNIT TO RAIN OR MOISTURE.
PLEASE NOTE: There is Low, Mid and High equalization for
each channel with an extremely wide range of adjustment.
7. DO NOT USE ANY SPRAY CLEANER OR LUBRICANT ON ANY

CONNECTIONS
1. Before plugging in the power cord, make sure that the VOLTAGE
SELECTOR (2) switch is set to the correct voltage.
4. KILLING FREQUENCIES: There are two ways to kill frequencies,
using the LOW (25, 38) ,MID (26, 39), and HIGH (27, 40) KILL
SWITCHES. Each Kill Switch has three positions, latch, normal and
flash. When you move the selected KILL SWITCH to the top LATCH
(ON) position, the switch will stay there, and the frequency will be
killed. When you move the selected KILL SWITCH to the center
position the kill function is not active, and the frequency will not be
killed. When you move the selected KILL SWITCH to the bottom
FLASH position and hold it there, the frequency will be killed.
Releasing the selected KILL SWITCH from the bottom position will
bring it back to the center position and the frequency will no longer
be killed.
NOTE: This product is double insulated
and is not intended to be grounded.

will be on and the volume of all sources except the Mic input are
lowered by 16 dB. MIC LEVEL (17) controls the level of the MIC.
The MIC EQ (16) control allows you to fully adjust the tone of the
MIC.
