FRONT PANEL CONTROLS AND INDICATORS

FIGURE 1

1.Input Gain Control: For best performance, adjust each Input Gain Control so the associated Input Peak LED illuminates red only on the loudest signal peaks.

2.Input Low-Cut Filter Switch: Provides low-frequency roll–off to reduce wind noise and rumble. When using the filter, the frequency response is down 7 dB at 150 Hz. Roll-off slope is 6 dB per octave.

3.Input Peak LED: Illuminates at 6 dB below clipping.

4.Limiter Switch: Activates a fast-acting, peak-responding limiter optimized for speech. An internal modification can provide a slower release time for music signals (see DIP Switches).

5.Output Peak/Limiter Bi-Color LED:

Red	=	output signal at +12 dBm
		(6 dB below clipping)
Green	=	output signal at limiter threshold
		(when limiter is on)

6.Output Level (VU) Meter: Meter response approximates true VU characteristics (about 300 ms rise and fall, 1% to 5% over shoot). For a slower response, see Internal Modifiable Func- tions. 0 VU is switchable between +4 and +8 dBm (see DIP Switches). When using batteries, use the BATT CHECK switch to illuminate the meter.

7.1 kHz Tone Oscillator Switch: Sends a 1 kHz tone to all out- puts and mutes all inputs. The MASTER control adjusts tone level.

8.Battery Check Button: Press and hold to show battery level on the VU meter. Press once to illuminate the VU meter for 10 seconds, or set DIP switch 6 to toggle the meter light (see DIP Switches).

9.Power-On/Off Switch: Turns the mixer on and off.

10.Power-On LED:

Green = power on

Flashing = low batteries (about 30 minutes of operation remaining)

11. Dual function control knob:

Headphones Gain Control: Rotate to adjust headphone level.

Pull/Monitor Switch: When using headphones, pull out to listen to audio from the MONITOR IN jack. Add attenuated program signal using DIP switch 4 (see DIP Switches).

WARNING

The headphones circuit can produce high volume levels that can damage the user’s hearing. Make sure headphone volume setting (PHONES) is low (Full CCW before putting headphones on.

12.Headphones Outputs: Stereo 1/4 in. and 3.5 mm phone jacks.

13.Master Gain Control: Sets mixer output gain. Set to 0 dB position for unity gain.
