DESCRIPTION The Electro-Voice 7100 stereo power amplifier utilizes proven design concepts to provide an ultra-reliable amplifier with virtually unmatched performance characteristics. It achieves this success without increased complexity or cost, making it a real value. Each channel delivers over 75 watts of continuous average power into 8 ohms or over 100 watts into 4 ohms over the full audio frequency range. In the bridge mode, the amplifier can deliver more than 200 watts into an 8-ohm load at less than 0. 10% THD. The maximum midband output power is 100 watts per channel into 8 ohms and 145 watts per channel into 4 ohms at less than 1% THD. Four output devices are utilized for a total device power dissipation of 520 watts. Because the large heatsink area allows more than adequate dissipation, the amplifier is convection cooled and performs in total silence. The single rackspace (1. 75 in. ) chassis height makes for convenient installation. Each channel is independently protected against excessive output voltage, excessive phase shift, radio-frequency interference, shorted loads and overtemperature. The load is protected against startup and shutdown transients, DC faults, low ac voltage and subsonic signals.
