User manual PEAVEY 701R MIXER

[. . . ] Congratulations on your purchase of a Peavey Electronics IATM Series power amplifier. Please read this manual carefully (especially the important Precautions section located inside the front cover) as it contains information vital to the safe operation of the amplifier. Also, please fill out and return the enclosed product registration card. The IATM Series power amplifiers represent new levels of value and flexibility never before offered to the contracting market. [. . . ] The amplifiers are ruggedly built from high quality components and feature comprehensive protection circuits to protect your amplifier from those "real world" occurrences. CLIP LIMITING At the amplifier's full power, or clipping point, the channel gain will automatically be reduced, guarding the loudspeakers against damaging high power and continuous square waves that would otherwise be produced. this is indicated by illumination of the Clip LED. Normal program transients will not trigger Clip Limiting; only steady or excessive clipping will. The first amplifier in the chain requires an SPST closure between its "ENABLE IN" terminal and "24V DC+" terminal to initiate the power turn-on sequence and keep the amplifiers in the chain powered on. This function may be performed under computer control if equipped with an optional module containing sequential capability. If this optional module is used, no connections need be made to the plugable terminal. 05% @ 150W from 20 Hz - 20kHz with both channels driven THD (2 x 8 ohms): < 0. 05% @ 100W from 20 Hz - 20kHz with both channels driven THD (1 x 4 ohms): < 0. 4 volts @ 8 ohms Input Impedance: 20 k Hum and Noise: > -105 dB, "A" weighted referenced to rated power Crosstalk: > -75 dB, "A" weighted referenced to rated power @ 8 ohms Current Draw @ 1/8 power: 330 watts @ 4 ohms, 230 watts @ 8 ohms Current Draw @ 1/3 power: 550 watts @ 4 ohms, 330 watts @ 8 ohms Idle Current Draw: 25 watts in Standby Mode Maximum Current Draw: 800 watts @ 4 ohms, 510 watts @ 8 ohms Thermal Emissions (btu/hr. ): 1, 364 @ 1/3 power 4 ohms, 443 @ 1/3 power 8 ohms Cooling: 80mm DC fan, off until heatsinks reach 45o C, then variable speed Controls: 2 rear panel attenuators, sequential turn on/off Indicator LEDs: 2 Clip, 2 Signal, 2 LFC, 1 Protect, 1 Power Protection: Temp.

[. . . ] According to OSHA, any exposure in excess of the above permissible limits could result in some hearing loss. Ear plugs or protectors h1 the ear canal]s or over the ears must be worn when operating this amplification system in order to prevent a permanent hearing loss if exposure is in excess of the limits as set forth above. To ensure against potentially dangerous exposure to high Sound pressure levels. It is recommended that all persons exposed to equipment capable of producing high sound pressure levels such as this amplification system be protected by hearing protectors while this unit is in operation.
