FlexPhones Master Installation and Operation Manual
DESCRIPTION
Product Description:
The FlexPhones Master is a professional Broadcast/Studio six channel dis-
tributed headphone system with independent talkback capabilities. Each of the six
channels provides stereo program monitoring and selective talkback with intercon-
nection via CAT5 cable to multiple Active Headphone Remotes (AHR-1) and/or the
Monitor Selector Interface (MSI). Multiple masters may be cascaded to form larg-
er systems. The FlexPhones Master is equipped with inputs for stereo program and
talkback audio. Rear panel program and talkback trimmers are provided to pre-set
maximum input levels. The microphone/line level talkback input is available via a
rear panel plug-in euroblock connector, while the front panel XLR connector facili-
tates the use of a user provided gooseneck microphone or headset. The front panel
is equipped with a level control for local headphones with both 1/4” and 1/8” stereo
headphone jacks. The six front panel talkback switches allow the user to independ-
ently communicate with each AHR-1 listener and can be configured to insert talk-
back audio into only the left or both ears and dim either or both program channels.
Any combination of switches may be pressed, while the “All-Call” interrupts all lis-
teners. The Talkback function can be remotely controlled. Six RJ45 jacks are pro-
vided to distribute audio and power via CAT5 cable to the AHR-1’s, and/or MSI’s
that conform to the StudioHub+ wiring format. Low-Z balanced audio distribution
is used to preclude audio degradation with long cable runs.
Additional features include:
Front panel power and talkback LED indicators, surge protected internal bi-
polar 24/15-vdc-power supply affording superior headroom and high definition
audio. The optional Monitor Selector Interface (MSI) provides transparent audio
switching of the program and talkback functions into a studio’s monitor system. The
MSI is inserted between a studio’s air or console’s monitor feed and monitor ampli-
fier. The MSI may be connected to the FlexPhones Master or AHR-1. All audio
connections are balanced and supplied on plug-in euroblock screw terminals.
The FlexPhones Master half rack profile, allows the unit to be set on a desk-
top, mounted on a wall or the RA-1, Rack-Able mounting shelf. The AHR-1 may
be desktop mounted, under counter or with the optional HR-1/MP or HR-1/MP-XLR
mounting plates, which may be turret mounted.
