2–Names and Functions of Parts

Front panel

1

POWER switch and LED

Turns power ON and OFF.

2

LED indicators

Indicate the presence of input signals.

3

TRIM (BALANCED TO UNBALANCED) 1–4

These semi-fixed trim controls allow output signal

levels to be adjusted in a range of ±12 dB.

4

TRIM (UNBALANCED TO BALANCED) 5–8

These semi-fixed trim controls allow input signal

levels to be adjusted in a range of ±12 dB.

Rear panel

5

OUTPUTS 1–4

RCA pin jack type output connectors with nominal

output levels of -10 dBV (0.3 V).

6

INPUTS 5–8

RCA pin jack type input connectors with nominal

input levels of -10 dBV (0.3 V).

7

OUTPUTS 5–8

XLR type output connectors with nominal output

levels of +4 dBu (1.23 V) or -20 dBu (0.0775 V).

8

INPUTS 1–4

XLR type input connectors with nominal input

levels of +4 dBu (1.23 V) or -20 dBu (0.0775 V).

GND LIFT switches

In a studio or other place where multiple units are

connected, a ground loop can occur through the

wiring, and this loop can cause a hum or other

noise. If this occurs, engage

GND LIFT

switches to

cut ground loops from the (balanced)

OUTPUTS

7.

NOTE

The GND LIFT switches do not cut the ground for the

q

ALL LIFT switch

When other equipment is mounted in the same

metal rack, for example, a ground loop can occur

through the panel or chassis, and this loop can

cause a hum or other noise. If this occurs, engage

the

ALL LIFT

switch to cut the loop.

w

Level indicator LED switch

If this switch is ON, LEDs light when input signals

are present. If this switch is OFF, the LEDs do not

light regardless of the presence of input signals.

e

GND connector

When multiple pieces of equipment are connected,

use this to make the chassis of each piece of

equipment have the same electrical potential.
