Re-designed for 2014, the PPA T45 features a range of advanced digital input options, including AES and SPDIF.  These help the T45 integrate seamlessly into modern AV systems. Designed for large venues, the T45’s 1000 foot signal range is ideal for facilities where extended coverage is essential.

The unit’s three powerful microprocessors allow the T45 to program itself, taking the guesswork and complexity out of setup and configuration. Just use the high-resolution LED screen to quickly select among the preset listening options (voice, music, or hearing assist) to instantly apply the ideal audio settings.
