Audio Resolution's HA-8-VCA analog, modular, high-fidelity, 8-channel stereo studio headphone amplifier provides exceptional audio quality, with remote voltage volume control (VCA) ensuring proper left and right channel balance with natural stereo imaging. Featuring a fully analog signal path, the HA-8-VCA offers high dynamic headroom with minimal noise and distortion. It includes three balanced stereo audio inputs, eight stereo headphone outputs, and eight remote volume control units with input routing switches and headphone outputs. Ideal for professional recording and broadcast studios, the unit supports local and remote headphone output, VCA volume control, and high power independent of headphone impedance so everyone can use their go-to phones. Additional features include a wide regulation range, input selection routing switch, high-fidelity performance, high output power, and a 2RU rack-mountable design. The system can be downscaled to four stereo headphone channels and includes eight remote headphone volume control units.
