This may be recalibrated for each meter by an internal trim potentiometer. See the VU Meter Adjustment paragraph for instructions. Note: Mechanical meters are used because LCD meters do not operate properly in cold weather; fluorescent meters drain batteries too quickly; and LED meters are difficult to see in sunlight.

Channel Inputs: The three female XLR inputs are transformer balanced for superior rejection of hum, RFI, and other interference. Each input can provide 48 V or 12 V phantom power (for condenser microphones); 12 V T (A-B) power (for condenser microphones); or no power (for dynamic microphones). See the Internal Switches and Controls section. 2.

ENGLISH ENGLISH 3. Slide the Limiter switch to the Off (down) position. 4. Adjust the Left Master gain control until the ac voltmeter reading is at the desired peak output level. 5. Open the battery compartment and turn the Peak LED L trim pot completely clockwise. 6. Slowly adjust the trim pot counterclockwise until the left Peak/Lim LED first illuminates red. 7. Repeat the above procedure for the right Peak/Lim LED, using the Peak LED R trim pot.
ENGLISH ENGLISH C in PF= (85/frequency) - .33 Example for 200 Hz corner frequency 85/200 = .43 .43-.33 = .1 PF Decreasing Tape Out Level to Mic Level 1. Locate R1112 and X511 (the top side of the bottom PC board, by the L Out XLR connector). 2. Locate R1114 and X510 (the bottom side of the bottom PC board, by the Tape Out jack). 3. Remove R1112 and R1114. 4. Solder a jumper through the holes at X511. 5. Solder a jumper through the holes at X510. For a 200 Hz corner frequency, use a 0.1 PF capacitor. 2.
ENGLISH ENGLISH Overload and Shorting Shorted outputs, even for prolonged periods, cause no damage. Microphone inputs of up to 3 Vrms cause no damage. The Line and monitor inputs can withstand signals of up to 30 Vrms. Input Channel Bi-Color LEDs Green: Signal presence; visual indication of mix level. Red: 6 dB below clipping level. Output Peak/Limiter Bi-Color LEDs Green: Output being limited by 1 dB or more. Red: Output peak threshold reached; factory set at +17 dBm; user adjustable from 0 to 17 dBm.
ENGLISH ENGLISH nications. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation.
