Product Overview
Williams Sound Personal PA Base-Station Transmitter; 500-Ft Range; RCA Inputs; Tunable between 72.1 and 75.9 MHz
If you're looking for an FM transmitter to use with your Williams Sound assistive listening device, consider the PPA T27. This compact base station transmitter pairs with Williams Sound PPA R37 or PPA R38 receivers to broadcast clear sound. As long as you have a compatible Williams Sound receiver, you can use this transmitter in movie theaters, classrooms, houses of worship, and more
The transmitter accepts audio via the RCA line input jack or 3.5mm mic jack, and transmits the audio over an FM radio signal to any separately available, compatible Williams Sound receiver, as long as it is tuned to the same frequency as the transmitter
The compact size of the transmitter allows you to place it virtually anywhere, and it's designed to be easily used by anyone. An LED display shows the frequency, and a handy level adjustment control is located on the front panel for setting the audio level. Frequency selector buttons let you set the operating frequency at one of 17 steps between 72.1 and 75.9 MHz. The included antenna sits neatly on top of the transmitter and provides transmission distances of up to 500'
