The PRF76 integrates a powerful, high-quality headphone amplifier, an “On AIR” indicator and an illuminated push-button in a single housing.

It features a balanced left and right input, as well as a control input with automatic program attenuation.

Audio and power are supplied via an international-standard RJ45 cable.

Expansion to other PRF76 modules is via a single RJ45 cable from the PRF76's upstream OUT output to the downstream input of the next module. This saves a lot of wiring time. The three audio modulations are distributed in this way, as is the power supply.
