User manual PEAVEY IPA 75-150T II

[. . . ] SPSTM eliminates power amplifier clipping. ACTIVITY (SIGNAL PRESENT) LED (5) Indicates signal presence at amplifier output. Illuminates when output is approximately 35 dB below full power. POWER SWITCH (6) Depress to "on" position to turn on. 3 INPUT SCREW TERMINALS (7) Provides an electronically balanced input, nominally 100 mV to 1 volt (see Sensitivity Switch). For unbalanced inputs, use the (+) and (-) terminals. 24 V DC OUTPUT TERMINALS (8) Provides connection for a low current (20 mA) 24 V DC output for powering low current external addon equipment. SENSITIVITY SWITCH (9) Switches the input sensitivity from 100 mV to 1 volt. OUTPUTS (10) A direct output, as well as several isolated transformer outputs, are provided to allow the proper interface between the amplifier and the speaker system. The direct output allows direct connection to a 4 ohm speaker system. [. . . ] The unit shall have LED indicators to show Power, Activity, and SPSTM compression. The unit shall have a front panel level control, as well as a defeatable subsonic filter. The unit shall be packaged in a rugged metal chassis 17" wide by 3 1/2" high by 15 5/8" deep. The unit shall operate from standard 120 volts AC, 60 Hz power. The internal power amplifier shall be capable of delivering 75 watts into 4 ohms and 8 ohms, as well as providing 25 volt and 70 volt balanced line outputs. The unit shall be capable of delivering rated power from 20 Hz to 20 kHz ±0. 5 dB into 4 ohms at its direct output at 0. 5% or less distortion with hum and noise at least 95 dB below rated output. The unit shall be called the Peavey Architectural Acoustics Division model IPATM 75T II.

Read all safety and operating instructions before using this product. All safety and operating instructions should be retained for future reference. [. . . ] All service work should be done by a qualified service technician. This product should be used only with a cart or stand that is recommended by Peavey Electronics. Exposure to extremely high noise levels may cause a permanent hearing loss. Individuals vary considerably in susceptibility to noise induced hearing loss, but nearly everyone will lose some hearing if exposed to sufficiently intense noise for a sufficient time. [. . . ]
