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.
Product Datasheet
Overview
Specifications
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 pre-set 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 1/4” and 1/8” (3.5mm) jacks are provided. In addition, each Guest Pod has
a “cough button” and “mic-on” LED that can be wired to the user’s 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.
