To INPUT jack (unbalance)

A system for monitoring a single stereo source to the PHONES OUT up to a maximum of 50 persons. CASCADE OUT of Unit #1 is connected to INPUT (unbalance) of Unit #2, and so forth from Unit #3. If the INPUT knob of Unit #2 and later units are set to CAL, the output level of all headphones can be changed simultaneously by simply adjusting the INPUT knob of Unit #1 (Cascade connection must be limited to a maximum 10 units. Fostex cannot guarantee correct operation if this number is exceeded.).

This is a system for locating a PH-50 in each musician's booth, in which each musician can adjust the monitor balance to their preference during recording sessions. A monitor send exclusive for each musician is connected to AUX IN and monitor signals other than this is returned to the INPUT.

Each musician can thus set balance of the two monitor mix by adjusting the AUX and INPUT knobs of the PH-50.

*The PH-50 can also be rack mounted by utilizing the separately sold rack mount adaptor. The ROLAND CO., Model RAD-50 adaptor is recommended.

Recording Studio

During multitrack recording, a system can be made for sending the monitor signal from the MIXER to the musician's headphones and at the same time, send them talkback individually from the MIXER.
