CASCADE OUT
INPUT
AUX IN
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.).
Recording Studio

a system can be made for
sending the monitor signal
f r o m t h e M I X E R t o t h e
musician's headphones and
at the same time, send them
talkback individually from
the MIXER.

PHONES
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.
