Peavey introduces new smart power amplifiers for constant-voltage applications

Peavey Commercial Audio introduces the MediaMatrix sPower Series multi-channel smart power amplifiers designed for applications that require a large quantity of constant voltage output channels. The sPower Series offers seven different models of smart power amplifiers that support either 4- and 8-channel outputs at 75, 150, or 300 W per channel plus a hi-power 600 W/Ch x 4 option.

The units offer selectable 70 V RMS (true 100 V peak) or 100 V (true 140 V peak) output amplifier channels and Class-D output topology. They are cooled with a low-volume internal air-exchange system. A Switch Mode Power Supply (SMPS) helps to regulate power supply rails, delivering full specified power regardless of A/C power conditions operating anywhere between 85 to 250 V (43 to 63 Hz at 2400 W). Each unit has a 110 Hz high-pass filter with 12 dB per octave per selectable channel.

The serial RS485 control port, in conjunction with the MediaMatrix nWare 3.0 ControlManager software suite, allows for amplifier monitoring and control. Additionally, loudspeaker loads as low as 5 W rated output can be monitored. All sPower amplifiers are designed to enable the use of intelligent load limiting on the amplifier output stage, preventing overdrive and designed with protections against short circuits, overheating, over-currents, and DC over-voltage.

An automated high-power change-over relay per output channel provides an N/O connection allowing any of the internal amplifier channels to act as a backup in case the primary amplifier channel fails. Alternatively, an addition external amplifier channel to back-up the primary amplifier channel can be used for a true “n+1 redundancy” at the same output port without the need to physically change the speaker cable circuit.

Seven 2U rack mount models are available in the sPower Series: the sPower 754 and 758, respectively 4- and 8 channels offering 75 W per channel; the 1504 and 1508, offering 150 W per channel; the sPower 3004 and 3008, offering 300 W per channel; and the sPower 6004, with Hi-Power output of 600 W per 4 channel.
