Perfect for stage or studio!

With extensive switching functions, extreme efficiency, and unparalleled sound quality, the ultra-versatile Nady HPA-4 is a universal 4-channel multipurpose headphone amplifier and line distribution system that's perfect for the most demanding professional stage and studio applications.

The HPA-4 rackmount amplifier features 4 independent stereo high-power channels in a rugged 1U package - an ingenious, easy-to-operate unit allowing a maximum variety of both useful monitoring and stereo line level signal distribution options. It features a no-compromise circuit design, stringently selected tight-tolerance components, and low-noise, extremely linear op amps for reference-quality audio with maximum headroom even at extremely high headphone volumes.

Input source select switches plus 1/4" TRS stereo outputs on each channel and 4 independent stereo input sections (each with servo-balanced stereo 1/4" TRS jacks) enable independent selection of any of the 4 stereo signals for each headphone amp/line distribution channel. This capability allows selecting from up to 4 completely independent monitor signals for each set of headphones connected to the Nady HPA-4 for optimum monitoring flexibility or 4 separate choices for each channel's line output for enabling many useful, simple audio switching/routing solutions. Up to 4 HPA-4s can be daisy-chained for even more options.
