PRODUCES UP TO A 10 WATT BROADCAST SIGNAL
The DRTXM4 Synchronized Audio Transmitter is the highest-efficiency HAR transmitter manufactured. It produces a strong signal to broadcast your highway advisory messages at the maximum legal power allowed by the FCC. The efficient DRTXM4 Synchronized Audio Transmitter does not require enclosure ventilation, even in the extremely hot climates, thus ensuring years of clean, dry and trouble-free operation. Comprehensive metering is clearly displayed on the front panel to indicate the transmitter is performing.
The DRTXM4 Synchronized Audio Transmitter is power adjustable to use the full 10W allowed by FCC and can be adjusted from 0-10W by an adjustment knob located on the side of the transmitter. When used in conjunction with the TCM-1 amplifier module, output wattage of up to 30W can be attained*.
- 0-10W signal adjustment
- Signal power up to 30W when used in conjunction with the TCM-1 amplifier*
- 100% modulation capable
