User manual PEAVEY IRM 8150

[. . . ] IRM 8150 Powered Mixer 1 Intended to alert the user to the presence of uninsulated "dangerous voltage" within the product's 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 ­ DO NOT OPEN!CAUTION: To reduce the risk of electric shock, do not remove cover. [. . . ] It is, however, unlikely that the gain matching of the mic and line will allow this hookup to be useful. PHANTOM POWER ON/OFF (19) This switch selects phantom power "ON" or "OFF" for all channels. Phantom power is on when the switch is in the in position and off when the switch is in the out position. This switch should be activated for use with condenser-type microphones. Phantom voltage is +48 V DC on pins 2 and 3 referenced to pin 1. MAIN OUTPUT (20) This 1/4" jack provides a signal from the main system mix before the graphic equalizer. Used primarily to feed an auxiliary amplifier/speaker system. MONITOR OUTPUT (21) This 1/4" jack provides a signal from the MONITOR mix for an external monitor amplifier/speaker system. The level is determined by the channel monitor and master monitor controls. AUX OUTPUT (22) This 1/4" jack provides a signal from the AUX mix for external effects or signal-processing equipment. This output can also be used for other purposes if external effects are not required. These include building a separate mix for recording or broadcasting. GRAPHIC INPUT (23) This 1/4" jack provides an input to the internal graphic equalizer/power amp. This is a switching jack: a signal inserted here interrupts the normal signal path from the main bus into the equalizer. OPERATION NOTE: This jack permits the equalizer to be switched away from its normal input and accept an external signal to be equalized, such as the monitor output. GRAPHIC OUT (24) This 1/4" jack provides access to the output of the internal graphic equalizer. A plug inserted into this jack does not switch the EQ output away from the input to the power amplifier. AUXILIARY INPUT (25) This 1/4" jack provides access to an input to the main mixing bus for patching in returns from external effects devices, extra mixing channels, etc. Using this jack defeats both tape in jacks. POWER AMP INPUT (26) This 1/4" jack provides access to connect external line-level signals to the power amplifier. OPERATION NOTE: This jack permits the internal power amplifier to be switched away from its normal input and to accept external line-level signals. AC POWER AND POWER AMPLIFIER OUTPUT SECTION: FUSE (27) The fuse is located within the cap of the fuseholder. [. . . ] For more information on grounding, write for our free booklet "Shock Hazard and Grounding. " Power supply cords should always be handled carefully. Never walk 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. [. . . ]
