System Overview
Thank you for choosing the Enersound T-500-4 FM 4-channel transmitter. This
professional transmitter is designed for assistive listening and language
interpretation. It wirelessly broadcasts a speaker’s voice, music or any audio signal
up to 1000 ft. (305 m). The audience can use the optional R-100 FM receivers, R-120
FM multichannel receiver or any other compatible FM receiver operating on the 72-
76 MHz frequency to pick up the broadcast. The T-500-4 transmitter features 3 main
audio inputs that allow the direct connection of virtually any analog audio source,
including a 3.5 mm jack for headset microphones, an XLR & ¼ inch combination jack
with a selector for dynamic microphones, condenser microphones or line-level
signals, and a RCA line auxiliary input. It also has a recording output and a 3.5 mm
monitor headphone jack.
For language interpretation, it has a unique integrated interpreter monitor function.
This feature allows interpreters to select an external incoming audio source and
utilize a headset with microphone to listen to the source language without the need
of an interpreter console or external headphone amplifier. Through the
headphones’ volume control, interpreters can set the desired incoming audio level
and the [MUTE] button allows them to momentarily silence their microphone for
coughing or sneezing. For more advanced interpreting functions, it can also be
utilized with the Enersound IC-12 multi-channel interpreter console or with any
other interpretation platform with analog audio outputs.
Its LCD display allows to easily program the various useful functions, such as test
tone, RF power level, display mode (frequencies or channel numbers), and channel
lock.
