The HA4700 is a multi-purpose headphone amplifier system for stage and studio applications. It offers four independent high-power amplifiers that can drive loads down to 8Ω. Each channel can be switched to operate as stereo or double mono and has a stereo AUX input in addition to the stereo main input so each performer can adjust their own level against the overall mix.

Additional features available on each channel include high and low EQ; left/right mute switches; output level control with 8-segment LED meter; one front and two rear output connectors

There’s also a direct front panel input connector for easy connection of any sound source, parallel main outputs that allow cascading of several amplifiers, ALPS® potentiometers and a toroidal power transformer for quiet and reliable operation.
