RHA6

6-Channel Headphone Amplifier
(Discontinued Product)


The RHA6 is a 6-channel professional headphone amplification system perfect for studio and live event monitoring. AUX and Direct inputs make it possible to create custom headphone mixes, and additional features such as direct line outputs to connect additional RHA6 units and three headphone outs per channel provide maximum versatility. RHA6 has a minimized circuitry path which means there's less “stuff” for your signal to pass through, keeping your sound clear and crisp.
