Electrovoice 7100 Power Amplifier 2 x 75 Watts at 4 Ohms 1RU Convection Cooled for Zero Fan Noise Reviews & Ratings
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 mid band 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 rack space 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 over temperature.
The load is protected against startup and shutdown transients, DC faults, low ac voltage and subsonic signals. A unique current-limiting circuit was designed specifically for the amplifier.
It features a variable current limit which is a function of the output signal voltage.
As a result, the amplifier can deliver the rated currents into rated loads, but substantially limits the current into low impedance or shorted loads shorted output terminals.
Once the short is removed, however, the amplifier will resume normal operation.
