DESCRIPHON
The 7600 is a dual-channel power amplifier
lor prolesslonal sound relnlorcement.

Each channel delivers more than 400 watts oi
continuous average power into 8 ohms or 600
watts into 4 ohms over lull audio frequency
range. In the bridge mode. the amplifier can
deliver more than 1200 watts at less than
0.10% THD into 8 ohms.

Each channel is independently protected
against...

U Over temperature

- Excessive output voltage

0 Excessive phase shift

0 Radio-frequency lnterterence

0 shorted loads

The load is protected from surtup/shutdown
transient. inlrasonlc signals. low ac line
voltage. and dc. When a problem is detected.
an output relay automatically disconnects the
load from the channel and illuminates the
Protect LED located on the front panel.

The 7600 has electronically balanced inputs
and accessory sockets for plug-in translorm-
ers and electronic modules. The level controls
are rear mounted to avoid accidental
changes. The standard power translonner
permits operation at 120/240 V ac. 50/60 Hz.
A 100-V-ac. 50/60»Hz model is available. The
Electra-Voice 7600 power amplifier Is the
choice Ior serious prolessional installations
which demand the highest quality at high
power levels tor extended periods oI time.
