FEATURES and FUNCTIONS

INPUT:

Each of the four individual channels has three standard ¼" unbalanced, high
impedance bridging jacks for connection to instruments and amplifiers. All are wired in parallel
and can be used in any combination for input and through connections. Two are located on the
rear panel with the third on the front.
OUTPUT: A three pin male XLR low impedance output is provided for each channel to connect
the DI to the sound board microphone input. Pin 2 is wired in phase with the tip of the ¼" input.
GROUND LIFT SWITCH: In the lift position, the input ground is disconnected from pin 1 of
the output XLR. This can be very useful for eliminating buzz and hum between onstage
equipment and the PA system.
PAD SWITCH: When switched to the in position, a 20dB pad is inserted across the input. This
attenuates very hot input signals such as amplifier speaker outputs or some keyboards. The pad
only affects the balanced XLR output.
