Comtek BST 25-216 overview

  • 1Description

The BST-25/216 Synthesized Base Station Transmitter from Comtek is an auxiliary base station transmitter designed to operate in the newly assigned 216-217MHz band under part 95 of the FCC regulations. For highest fidelity operation, the PR-216 receiver must be used with the wide-band companded channels.

This transmitter may be used for personal cueing, for tour guide applications, language interpretation and for assistive listening. The BST-25/216 also operates with the Phonak microEar VHF in-ear receiver in the narrow-band non-companded channels.

The BST-25/216 transmitter incorporates the latest digital and analog technologies to produce low residual noise, wide dynamic range, and extended frequency response rendering the most natural sound possible from a wireless system.

57 user-selectable channels in the 216 to 217MHz range: 38 standard narrow-band, non-companded channels; 19 high-fidelity narrow-band channels with companded audio processing
Single window, bright LED display for exact frequency and channel, VU bar graph meter, antenna condition and lock-out indicator
Test tone generator for receiver testing and audio level referencing
Balanced mic or line level with 60 dB of control range to accommodate any audio level
Micro controller automatically sets the modulation deviation, audio mode for processing, and the EQ when corresponding channels are selected
It can be rackmounted for AC or 12 V DC power and can accommodate a variety of remote antennas
