Like its big brother, the compact PH-50 is a supremely quiet headphone distribution amplifier with each output having its own amplifier as well as its own level control. The PH-50 is ideal in the studio as a mixer output can send a talkback signal to the Aux input (with level control) which can then be distributed to all headphone outputs. Multiple PH-50s can also be cascaded to handle a large number of listeners making it ideal for orchestral, multimedia, education and trade show applications. Flexibility is further enhanced with all five outputs being available both on the front and rear panels.
