Introduction
This document describes setup, adjustment, and operation only; detailed
maintenance information is not included. If you have any questions, consult your
dealer or the Vega factory.
Your Vega Model RMT-10 is a single-channel VHF FM transmitter. It transmits a mono
audio signal to compatible receivers (typically Vega PL-2s). The RMT-10's “transmitter
module” ( PCB) can be swapped (by authorized personnel) to allow operation on a
different frequency—any one of over 1,600 different frequencies between 169 MHz
and 216 MHz. Consult your dealer or the Vega factory for details.
The RMT-10 accepts either line or mic audio via a standard XLR connector. The “input
level” switch allows selection between mic (–40 to –10 dBu) or line (–10 and +20 dBu)
audio input. RMT-10s may also be internally programmed to work with Clear-Com or
RTS wired intercom systems (“receive-only” mode). The RMT-10 may also be
configured to pass a 70-volt speaker line (input up to 250 volts push-to-talk).
Fine audio-level adjustments may be made using the 30-dB variable attenuator
conveniently located on the front panel. To improve intelligibility, the transmission
signal may be adjusted via “frequency compensation” and “audio compression”
controls. Two “frequency compensation” controls for boosting or cutting the low and
high frequencies are provided on the rear panel. The “audio compression” control
limits dynamic range by either a 2:1 logarithmic compressor or a wide-range
automatic level control (ALC) system. See the “Adjustments” section for details.
Noise reduction is achieved with a proprietary two-ended compander system that is
always active. The compander is compatible with Vega's PL-2 portable VHF receiver.
A 1/4-wave “whip” antenna is provided with the RMT-10. Other antennas, such as the Vega
Model 123U dipole antenna, may be used to facilitate rack-mount installation or to improve
coverage where the standard whip antenna would otherwise be blocked or shielded by
equipment cabinets or large objects.
