[. . . ] control on that channel is turned all the way down - otherwise a feedback loop will exist which could cause oscillation and possible damage to speakers. Care must be taken to insure that the amplitude of the return signal is not too great for the preamp channel input. However, by inserting a 1/4" phone plug into the PWR. AMP INPUT jack, the normal signal path is broken and any signal carried by the phone plug becomes the power amplifier's input.

Possible uses of this feature include dedicating the power amp to the monitor system while employing an auxiliary power amplifier for the mains, or using the SR power amp as one of the two power amplifiers in a biamped system (this would require the addition of an external crossover). These are the speaker outputs for the built-in power amplifier. Do not connect loads with impedances lower than 2 ohms to the SPEAKER OUTPUT, as this may result in amplifier overheating which will cause the SR mixer to eventually self protect, "turning off" for a period of time. (To calculate the speaker impedance, see Section 4-3-2. ) In addition, be sure that the speaker cable you use is of adequate gauge; otherwise, power will be lost in the wire instead of being delivered to the speaker. AC Power to the SR powered mixer is turned on and off by a rocker switch located on the back panel. If you have any external signal processing devices patched to the system, turn them on first to avoid pops in the loudspeakers. Also, when you turn on the mixer, make sure that the main fader is down - this eliminates the risk of the system immediately feeding back when it is turned on, and also minimizes turn-on-pops. Do not remove the grounding prong of the AC plug. To do so risks exposure to potentially lethal voltages and voids the warranty. FIGURE 1 illustrates the simplest way to set up your PA system. When you first set up the sound system, initial settings are critical for arriving at a satisfactory mix quickly. Often, to the distress of many sound engineers, the show must begin without a preliminary sound check. The following recommendations should help to alleviate some of the engineer's headaches. Set the channel HIGH, MID, and LOW frequency controls to their mid positions, and also set the GRAPHIC EQUALIZER to its mid or flat position. Set the MAIN MASTER and MONITOR MASTER controls to around the 1o'clock position. Adjust the MAIN controls to the approximate level you desire, with a mix that you feel will be acceptable. Most groups like to hear their voices in the monitors; some also like to hear certain instruments as well (keyboard, acoustic guitar, and so forth). [. . . ] LEVEL BRIGHT 0 0 MAX.
