Installation

Remove all packing materials. Check that all foam and plastic padding has been removed.

Secure the equipment into a 19" rack. Connect all cables.

Before plugging the unit in, always make sure that the power supply matches the product specification

voltage. Do not attempt to operate a 120V specification product on 240V power, or vice versa. Do not

supply power before

The balanced phone jack inputs have a nominal impedance of 20 KΩ (10KΩ with unbalanced wiring)

and will accept the line level output of most devices. The correct input depends on 2 factors: (1) whether

the input signals are balanced or unbalanced, and (2) whether the signal source floats or has ground

reference. Figures provide examples of recommended connection techniques for each type of signal

source. The optional connector is shown.

The amplifier's built-in 1/4"-Input-Phone-Connectors can be wired similarly for balanced or unbalanced,

floating or ground-referenced sources.

The phone connectors have a standard Tip-Ring-Sleeve (TRS) – configuration: The tip is positive (+), the

ring is negative (-) and the sleeve is ground.

a) Jack-Inputs Balanced Signals

Tip=HOT, Ring=COLD, Sleeve=Ground

b) Jack-Inputs Unbalanced Signals

Tip=HOT, Sleeve=Ground

c) XLR INPUTS Balanced Signals

Pin 1=Ground, Pin2=HOT, Pin3=COLD

all components of the system are

set up and connected properly.
