User manual PEAVEY HORIZON II

[. . . ] WARNING: When using electrical products, basic cautions should always be followed, including the following: Do not use this apparatus near water. Do not block any of the ventilation openings. install in accordance with manufacturer's instructions. Do not install near any heat sources such as radiators, heat registers, stoves or other apparatus (including amplifiers) that produce heat. [. . . ] When a cart is used, use caution when moving the cart/apparatus combination to avoid injury from tip-over. Thank you for using Peavey Architectural Acoustics!Eight input ports accept MMATM plug-in modules · Optional rack mounting with included rack ears Presentation rooms board rooms courtrooms auditoriums lecture halls meeting rooms Power Indicator The green LED indicates when AC power is supplied to the unit and the power switch is on. Low EQ Control (Bass) This is an active equalization control that adjusts the low frequency. Clockwise rotation boosts low frequencies and counter-clockwise rotation provides a cut in low frequencies (±10 dB). When IN the EQ controls are inactive and the EQ is flat. mute Bus Indicators The red LEDs indicate the status of each mute bus. Each LED lights when its appropriate mute bus is activated. Master Level Control Controls the overall level of the system. AC Power Receptacle This receptacle is for the IEC line cord (included) that provides AC power to the unit. Never break off the ground pin on any equipment. Preamplifier Out Provides a line level output of Master Level mix output to drive external devices such as signal processors, hearing assistance systems, or recording equipment. The input impedance of the equipment should be greater than 600 Ohms. Power Amplifier Input Provides a direct input to the power amplifier with an input sensitivity of 1 Volt. When an RCA phono plug is inserted into this input, the connection between the preamp output and the power amp input is internally disconnected allowing direct access to the power amplifier. Using this input along with the preamplifier output (#9), a signal processor can be inserted between the mixer and the power amplifier. Bridge In/Out Provides an output signal that is independent of the Master level, Low EQ, and High EQ controls. It also may be used as a mixing output point when the similar terminal of another mixer/amplifier is connected to this terminal. A separate tape recorder output may be taken from this point without interaction of EQ and Master level control. The input impedance of the equipment connected to this terminal should be greater than 10k Ohms. Program Input Provides an auxiliary input that accepts signals from other sources such as another mixer or mixer/amplifier. The signal level at this input is controlled by the PROGRAM level control on the front panel and is fed to the mix bus. [. . . ] Note: To provide adequate ventilation, leave at least one rack space between units when multiple amplifiers are mounted in the same equipment rack. For proper operation of this unit, do not place within 6" of any wall or combustible surface. Slide them between the card-edge guide rails and secure them with the provided screws as shown in Figure 3 . Ensure screws are sufficiently tightened for proper grounding. [. . . ]
