6-Channel Headphone Amplifier

The RANE HA6S is a universal, multi-purpose mixer and headphone amplifier for rehearsal, studio or stage. Perfect for headphones, in-ear monitors, or personal monitor mixing, HA6S features six independent high-power stereo amplifiers in one compact rack unit that delivers maximum audio quality, even at very high or very low volume levels; HA6S has a minimized circuitry path which means there’s less ‘stuff’ for your signal to pass through, keeping your sound clear and crisp.

  • Professional amplification system for studio and stage applications
