[. . . ] OPERATORS MANUAL DA 26 DISTRIBUTION AMPLIFIER QUICK START Are you in a hurry?For optimum system performance, we recommend reading the detailed Operating Instructions below and on page Manual-4. For those who can't wait, at least be aware of these points: · There are two inputs: Priority and Line. · The Priority Input accepts microphone or line level. [. . . ] SLOW = 230 ms (best for music), FAST = 11 ms (best for voice). The gain increase time constant is fixed at 1100 ms. 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. 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. OUTPUT trims and Crossover select switches: The ±12 dB trims set the levels for each of the six Outputs. High, Low or Full-Range is switch selectable for each of the six Outputs. Note: the Output trims do not affect Low-pass loudness compensation or Priority Input level. POWER indicator LED: This yellow illumination device lights up to let the operator know the thing is plugged in. Manual-2 REAR PANEL DESCRIPTION PRIORITY INPUT connector and MIC/LINE switch: The balanced PRIORITY INPUT operates at line or mic level, determined by the MIC / LINE switch. 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. 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. To complete an assignment, the Output must be selected by the PRIORITY ASSIGN port and Priority Detect must be active. Note that if a combination of Crossover Outputs is used in one zone, all Outputs serving the zone must be selected by the PRIORITY ASSIGN port. Variations in wire type do not greatly affect the performance of this port. However, 22-gauge stranded wire with a flexible jacket is recommended. [. . . ] Because the Remote Level control turns the low-pass Output down at a lesser rate than the high-pass or full-range Output, bass response is enhanced. 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. [. . . ]
