PPA T55 FM+ Transmitter with WaveCAST WiFi Technology – Williams AV

The PPA T55 FM+ Transmitter with WaveCast WiFi from Williams AV is a powerful FM transmitter perfect for interpretation and live translation settings where a longer (up to 1000 ft.) range is required.

Listeners can use an FM receiver or their own smartphone (via the WaveCAST Listening App) to support those who want to use their own headphones.



SKU: PPAT35 Categories: ,


The T55 FM+ transmitter uses a microprocessor to compress the signal for max clarity, and can broadcast on 17 preset channels in the 72.1–75.9 MHz range.

The FM+ WaveCAST WiFi connects to the installation location’s Wi-Fi Network. It does not provide a network on its own. The Wi-Fi network will need to be installed and established before the FM + can be used.

The T55 can be operated as part of a rack mounted standard 19” Rack, one EIA rack space high, 1/2 space wide. 1–2 units can be mounted in a single rack space with optional RPK 005 (single) or RPK 006 (double) Rack Mount Kits.
