[. . . ] · To avoid pain, never put headphones on your head and then plug them in. · Always start with the PHONES LEVEL turned down and then turn it up to the desired level. · Because of the high current and low output impedance, never short one side to ground or short left and right together as is possible with mono cup headphones. Note: Low power headphone stages typically use large resistors on their outputs, which allow shorting, but prevent high power. [. . . ] Note: Low power headphone stages typically use large resistors on their outputs, which allow shorting, but prevent high power. MASTER / CUE switch is used to select the HEADPHONES monitor source: · Use MASTER to rehearse your performance. This signal is the same as that at the MASTER OUT, but is not affected by the MASTER LEVEL control. · Use CUE to monitor the Program Input signal, so you can "Cue" a signal before fading in. This control allows you to PAN between Program 1 or Program 2. Manual-3 HEADPHONES jack provides a high current output, capable of driving headphones between 8 ohms and 600 ohms. Because the amplifier is capable of high current drive, it is important that the outputs are not shorted together or to ground. MASTER LEVEL adjusts the MASTER OUTPUT level for both the balanced and unbalanced outputs. The ground screw terminal may be used to solve potential grounding problems with other equipment. MASTER OUT includes two sets of stereo outputs: · The ¼" TRS jacks provide high current BALanced output, which should be used whenever driving equipment with a balanced input or running distances greater than about 10 feet. Due to the high drive capability and low impedance, never use a mono ¼" Tip/ Sleeve (no ring) cable in this jack; this grounds one side of the BALanced output. · Use the UNBALanced output for shorter runs, such as connecting to a recorder, looping to another mixer, or to other local signal processing or amplifiers. PHONO 1 and PHONO 2 inputs are RIAA compensated inputs with 18 dB per octave, 20 Hz rumble filters. LINE 1 and LINE 2 inputs are unbalanced line level inputs with a nominal sensitivity of -10 dBV. (HAMSTER switch out) PGM 2 inputs are sent to the right side of the Crossfader. (HAMSTER switch out) PHONO GND terminals provide an independent ground connect point for two turntables. It is very important that each turntable have a very good ground connection to one of these terminals. The thumb screws are not captivated, so use care not to spin them off and lose them. The MIC INPUT is a balanced ¼" TRS input specifically designed for a dynamic microphone. There is no engage switch, so the mic signal is always processed when you have an effects box connected. · The RETURN jack provides an input for the signal returning from your effects processor. · · · · · Manual-4 MIC LEVEL sets the gain of the Mic Input. Adjust the MIC LEVEL so that the OL indicator flashes only when you shout into the microphone. MIC TREBLE and BASS controls provide as much as 8 dB of boost or 8 dB of cut. [. . . ] use fully balanced wiring with shields tied to the chassis at the point of entry, or transformer isolate all unbalanced signals from balanced signals) then there is no guarantee that a hum free interconnect can be achieved, nor is there a definite scheme that will assure noise free operation in all configurations. WINNING THE WIRING WARS · Use balanced connections whenever possible. · Transformer isolate all unbalanced connections from balanced connections. · Use special cable assemblies when unbalanced lines cannot be transformer isolated.
