Altogether Now

Behringer's HA4700 offers four high-power amplifiers that can drive loads down to 8 Ohms. Each amplifier features its own two-band EQ, 8-digit LED output meter, left and right Mute switches, a ST./2-CH switch to toggle between stereo or double mono, and a 1/4" stereo Aux input to mix in any instrument or sound source. The front panel gives you one Phones Out 1/4" jack per channel. A Main section features a 5-segment LED output meter, Direct In 1/4" jack and Master Level dial.


On the back panel you'll find two additional 1/4" outputs per channel. That means up to 12 pairs of headphones can listen to four separate mixes at once. The back panel also features stereo 1/4" and XLR inputs and outputs so you can connect multiple HA4700 units for even greater listening capacity. Meanwhile, ultra low-noise 4580 operational amplifiers deliver outstanding audio quality.

Great Sound, Great Value

When a recording session calls for everyone's heads and ears to be in the game, the HA4700 is essential. Hearing is believing.
