11. MICROPHONE INPUT JACK: 

PLUG ONLY THE RANE MICROPHONE INTO THIS JACK--THE DC

POWER SUPPLY VOLTAGE SUPPLIED BY THIS JACK COULD BE DAMAGING TO ANY OTHER

MICROPHONE When the mic is plugged in, the display responds to whatever the mic picks up; when
the mic is unplugged, the jack automatically switches the display to monitor the output of the equalizer
section (see Section IV-9).

12. RTA LEVEL CONTROL: 

Use this knob to adjust the microphone level (or line level when the

microphone is unplugged) to properly drive the display. This control is accurately calibrated in dB-SPL;

any display band whose LED is green has the sound pressure level indicated by this knob (only with the

mic plugged in).

6. GROUND LIFT SWITCH: 

This switch provides the ability to separate chassis ground and signal

ground. Normally, this switch should be in the LIFT position. If you are tempted to try movingthis switch
with your power amplifiers turned on or turned up, DON’T BE. ALWAYS TURN YOUR AMPLlFIER LEVELS
DOWN BEFORE CHANCING YOUR GROUNDS AROUND and then bring them up slowly.

1. PINK NOISE LEVEL ADJUST: 

Use a 1/8" inch screwdriver to adjust the output from the Pink Noise

generator from 0 to 1.2 volts (-4 dBm) to match the input level requirements of the mixer or other
equipment driven by the generator.

2. PINK NOISE OUTPUT JACK: 

This is an unbalanced 1/4" jack which supplies Pink Noise to selected

equipment

3. EQ INPUT JACK: 

This is an automatic balanced/unbalanced 1/4" input to the equalizer section. Use a

mono 1/4" plug for unbalanced operation, or a stereo 1/4" plug wired as shown in the diagram below for
balanced operation.

4. EQ OUTPUT JACK: 

This is the automatic unbalanced/floating output from the equalizer section. Use

a mono%” plug for unbalanced operation, or a stereo 1/4" plug wired as shown in the diagram below for
use with balanced equipment (Refer to Rane Note 102 for further information on Rane’s floating output
system.)

5. AC LINE CORD: 

Plug this into a 120 VAC power outlet with grounding pin.
