REAR PANEL DESCRIPTION

1. PINK NOISE LEVEL ADJUST: Use a 1/8" screwdriver to adjust the output from the Pink Noise generator from 0 to

1.2 volts (-4 dBu) to match the input level requirements of the mixer or other equipment.

2. PINK NOISE OUTPUT JACK: This is an unbalanced ¼" jack which supplies pink noise to the sound system.

3. EQ INPUT JACK: This is an automatic balanced unbalanced ¼" input to the equalizer section. Use a mono ¼" plug

for unbalanced operation, or a stereo TRS ¼" plug wired as shown in the diagram below for balanced operation

4. 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 moving this switch with your power amplifiers turned
up, 

don't be. Always turn your amplifier levels down before changing your grounds around and then bring them up slowly.

5. EQ OUTPUT JACK: This is the automatic unbalanced/quasi-floating output from the equalizer section. Use a mono

¼" plug for unbalanced operation or a stereo TRS ¼" plug wired as shown in the diagram below for use with balanced
equipment (Refer to RaneNote 102 for further information on Rane’s floating output system).
