With extensive switching functions, extreme efficiency, and unmatched sound quality, the ultra-versatile HPA-4 is a universal 4-channel multi-purpose headphone amplifier/line distribution system — perfect for the most demanding professional stage and studio applications.

• Four totally independent stereo high-power headphone amplifier/line distribution channels in a convenient single rack package — an ingenious, easy-to-operate unit allowing a maximum variety of both useful monitoring and stereo line level signal distribution options.
• Input Source Select switches and Phone and Line 1/4" TRS stereo outputs on each channel, and 4 independent stereo input sections (each with servo-balanced L & R 1/4"TRS jacks) enable independent selection of any of the 4 stereo signals for each headphone amp/line distribution channel. This allows selecting from up to 4 completely independent monitor signals for each set of headphones connected to the HPA-4 for optimum monitor-ing flexibility or 4 separate choices for each channel's Line Output for enabling many useful, simple audio switching/routing solutions.
