User manual PEAVEY PZS 140

[. . . ] PZ S 1 4 0 TM M u l t i - Z o n e M i xe r / A m p l i f i e r ® ARCHITECTURAL ACOUSTICS® OWNER'S MANUAL Intended to alert the user to the presence of uninsulated Òdangerous voltageÓ within the productÕs enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons. Intended to alert the user of the presence of important operating and maintenance (servicing) instructions in the literature accompanying the product. CAUTION: Risk of electrical shock Ñ DO NOT OPEN!CAUTION: To reduce the risk of electric shock, do not remove cover. [. . . ] These LEDs will light whenever a signal level of 35 W RMS occurs in the associated zone. If these LEDs occasionally, flash only on peaks of the music or paging signal, audible clipping is probably not occurring. If these LEDs come on and stay on, then the power amps are clipping and audible distortion is probably occurring in that zone. OPERATION NOTE: These LEDs are only an indication of the level being sent to the power amps from the preamp. If a signal processor is used in the insert point, it must be set up in a way that it does not add/reduce the system gain. If the signal processor changes the signal level between the preamp and power amp the LEDs are no longer accurate. 10. 11. 12. 13. POWER SWITCH Rocker type switch, depress to ÒonÓ position to power unit. POWER LED Indicates when AC power is being supplied to the unit and the power switch is ÒonÓ. 14. 5 BACK PANEL: 15 16 20 17 21 18 22 25 19 25 24 26 26 23 BACK PANEL FEATURES: 15. FUSE The fuse is located within the cap of fuseholder. If the fuse should fail, IT MUST BE REPLACED WITH ONE OF THE SAME TYPE AND VALUE IN ORDER TO AVOID DAMAGE TO THE EQUIPMENT AND TO PREVENT VOIDING THE WARRANTY. If the amp repeatly blows fuses, it should be taken to a qualified service for repair. WARNING: THE FUSE SHOULD ONLY BE REPLACED WHEN THE POWER CORD HAS BEEN DISCONNECTED FROM ITS POWER SOURCE. AC LINE CORD SOCKET Provided to accept the removable AC line cord. Connect only to proper sourceÑsee back panel markings. CHANNEL 1 and 2 XLR INPUTS Normal low-Z mic inputs for cables fitted with a standard XLR male connector. The circuitry associated with this input is electronically balanced and is designed to accept any normal low impedance microphone. This receptacle is a standard three-pin XLR female wired as follows: Pin 1- ground Pin 2- positive input Pin 3- negative input OPERATION NOTE: 48 volt phantom power is always available on pins 2 and 3 with reference to pin 1. CHANNEL 1 and 2 LOW-Z INPUT Normal low-Z mic inputs for cables without connectors. Two conductor shielded cables should be carefully wired as follows: Cable shield- GND Conductor 1- Low-Z positive Conductor 2- Low-Z negative Normally conductor 1 should be the positive microphone output feed. If the polarity of the associated microphone is not known, one should be consistent in wiring all mics the same way. Again the circuitry associated with this input is electronically balanced and is designed to accept any normal low-impedance microphone. 6 17. OPERATION NOTE: 48 volt phantom power is always available on the + and - pins with reference to ground. CHANNEL 1 and 2 HI-Z INPUT Normal high-Z line input for cables without connectors. This high-Z input can be used for normal high impedance unbalanced microphones or other line level feeds. [. . . ] Never walk on or place equipment on power supply cords. Periodically check cords for cuts or signs of stress, especially at the plug and the point where the cord exits the unit. The power supply cord should be unplugged when the unit is to be unused for long periods of time. If this product is to be mounted in an equipment rack, rear support should be provided. [. . . ]
