The HDA400 headphone amplifier provides complete monitoring solutions for on-air studios, line remotes, houses of worship, production rooms, learning centers, home studios, or state-of-the-art recording studios.
The HDA400 is an economical four-output stereo monitoring system. A balanced 1/4-inch TRS stereo line input feeds a master level control, clipping indicator and stereo/mono switch. The HDA400 provides four independently adjustable high-compliance stereo outputs.
Each output comfortably drives typical 32 to 600 ohm headphones to sound pressure levels in excess of 120dB at 100mW each. Headphone output jacks are duplicated on front and rear panels. The HDA400 is a 19-inch, 1RU unit and includes an internal power supply.
