For those who can't wait, at least be aware of these points: · There are two inputs: PRIORITY and LINE. The PRIORITY Input accepts MIC or LINE level. [. . . ] The full counter-clockwise position disables the AGC. The normal range of operation is between 2:1 and :1 as marked by the gray band. 6 AGC SLOW/FAST release switch: determines the gain reduction time constant of the AGC circuit. SLOW = 230 ms (best for music), FAST = 11 ms (best for voice). The gain increase time constant is fixed at 1100 ms. 7 AGC GAIN meter: indicates the amount of AGC applied to the LINE INPUT. The 0 dB GAIN indicator is off if the Input is more than 26 dB below the Target Level. 8 CROSSOVER FREQUENCY switch and indicators: select the FREQUENCY for the 2-way Crossover when High-Pass and/or Low-Pass outputs are used (80, 110, 150 or 200 Hz). High, Low or Full-Range is selectable for each of the six Outputs. 9 OUTPUT trims and Crossover select switches: The ±12 dB trims set the levels for each of the six Outputs. High, Low or FullRange is switch selectable for each of the six Outputs. Note: the Output trims do not affect Low-pass loudness compensation or Priority Input level. 0 POWER indicator LED: This yellow illumination device lights up to let the operator know the thing is plugged in.

This Input accepts unbalanced signals, however, we do not recommend unbalanced operation unless the source is within 3 feet [one meter]; then only connect (+) and (GND). Note: the Priority Input is not influenced by the AGC, Crossover, Output trims or Remote Level controls. The gain range for MIC level Input is 30 to 60 dB. The gain range for LINE level Input is 0 to 30 dB. 2 PRIORITY ASSIGN port: The state of the PRIORITY ASSIGN port determines Priority Input assignment to each of the six Outputs. Assignment pins are active low with passive internal pull-up. Any combination of pins may be active at one time. The select ALL pin is provided for convenience. [. . . ] The corner frequency for loudness compensation is set by the CROSSOVER frequency selection. The reference level for the room is set with the OUTPUT trim on the front panel. Any Remote Level gain change results in automatic loudness compensation. A port for a wired Remote Level control is provided for each Output. [. . . ]
