Product Description
MultiPhones
is a multi-user distributed headphones system
for broadcast studio, professional audio, and
similar applications. It provides independent
stereo headphone listening facilities for multiple
users. The MultiPhones system consists of the
Master unit and up to 12 satellite Guest Pods
which are interconnected using standard CAT5 cabling.
The MultiPhones Master unit has inputs for stereo
Program audio and Talkback audio, Talkback facilities,
and a local headphone output. Master Level trimmers
for Program and Talkback allow the user to preset
maximum levels. The Talkback system allows a producer
or studio engineer to speak to the Guest Pod listeners,
overriding normal Program audio with a Talkback
microphone. The Talkback function can be remotely
controlled. Three RJ45 jacks are provided to distribute
audio and power to the Guest Pods.
Each
Guest Pod contains a stereo headphone amplifier,
volume control and headphone jacks. Both _" and
1/8" (3.5mm) jack are provided. In addition, each
Guest Pod has a "cough button" and "mic-on" LED
that can be wired to the useršs audio console
or other equipment.
The
MultiPhones system is optimized for use with contemporary
high-efficiency headphones with impedances between
24 and 600 ohms. Because each Guest Pod contains
its own amplifier, any combination of different
headphones can be used. There is no interaction
between units, and no degradation of audio performance
regardless of the number of Guest Pods used. The
system uses low-Z balanced audio distribution
so that long cable runs do not affect audio quality.
The MultiPhones Master unit is powered with a
built-in AC power supply. It is 1/3 rack width
and can be rack-mounted with the optional rack-mount
shelf, or cabinet or wall mounted using optional
cabinet/wall mounting brackets. The Guest Pods
can be flush-mounted in a tabletop cutout, or
mounted on a desktop or to a cabinet using the
optional desktop enclosure.
