Portable two independent stereo headphone amplifiers

For many years our GSGH2 twin headphone amplifier has been the 1st choice for professional broadcasters. The GS-HA008 builds on the GSGH2s specification and features to offer a modern robust portable twin headphone amplifier to supercede the GSGH2.

The GS-HA008 is a very useful twin headphone amplifier. It has wwo independent input channels that can be routed separately to left ear, right ear, or both, across both headphone amplifiers. Each input channel has individual coarse gain controls and each headphone amplifier has separate left/ right headphone volume controls.

For looping in large numbers, there is audio and power pass through. This makes the GS-HA008 suitable for audio monitoring in a dense environment such as an orchestra, where units can simply be looped together.
