The PPA T45 Transmitter is an FM Wide-Band transmitter operating in the 72-76MHz bandwidth. Compatible Williams Sound receivers include PPA R37, PPA R38, PPA R35-8 body packs and the PPA R1600 remote speaker. Developed for hearing assistance in places of public access, the PPA T45 is designed for those who need help overcoming background noise, reverberation, or distance from the sound source. It includes a complete audio processor optimized for the needs of hearing impaired persons and is easily integrated with your existing sound system. The PPA T45 can also be used with a microphone as a stand-alone system. The PPA T45 transmitter operates just like an FM radio station. The transmitter takes audio directly from a microphone or sound system. This audio is then broadcast over an FM radio signal. FM receivers can be worn by listeners, or the PPA R1600 AC powered amplified speaker with built in receiver can be utilized as needed. The broadcast can be received up to 1000 ft from the transmitter depending on environmental conditions. PPA T45 large area transmitter This allows listeners to sit anywhere in the area and listen to the broadcast at the level they need without disturbing others around them.
Two models are available - one with Ethernet control (PPA T45NET) and one without Ethernet control (PPA T45). The cutting-edge PPA T45NET transmitters offer control or monitoring capability from any remote location, multiple digital and analog audio input options, and an OLED high-resolution screen with easy-to-manage menu navigation.  Features 3 powerful microprocessors and the same high-quality audio and RF performance you have come to expect from Williams Sound.  It’s technology that takes the guesswork out of complex audio installation.  Simply select among voice, music, or hearing assistance in the application preset menu, and this transmitter quickly configures itself.  The PPA T45 shares all the same features as the PPA T45NET but does not have the network control capability. With a range of up to 1000 feet, the PPA T45 is ideal for large venues where superior coverage is essential.

The PPA R37 SelectTM Channel Receiver features a Seek/Scan function channel selector with access to 17 pre-set wideband frequencies between 72-76 MHz. PPA R37 receiverThe stylish, impact-resistant receiver offers crystal clear audio and is compatible with any Williams Sound Personal PA wideband transmitter. Systems are expandable, accommodating any number of listeners. Receivers include a detachable belt-clip for hands-free operation. A standard 3.5 mm stereo phone jack accommodates low-impedance mono earphones, headphones and neckloops (the ADA accessibility requirements for hearing assistance, requires one neckloop per four receivers or a minimum of two). The PPA R37 receiver is equipped with a integrated volume on/off switch and a green LED power on indicator. The green power on LED will illuminate red indicating low battery power. The PPA R37 receiver operates on two AA alkaline batteries for 50 hours of long-lasting operation. A battery selector switch inside the battery compartment also permits use of NiMH rechargeable PPA R38 receiverbatteries. Operating time with NiMH rechargeable batteries is approximately 32 hours.

The PPA R38 Multi-Channel receiver share the same ergonomically design features as the select-channel receiver. A on-screen channel selector with easy access to 17 pre-set, wideband frequencies (72-76 MHz) easily lets the user select the appropriate channel, be it for tour guide applications, audio description, language translations and/or in combination with a hearing assistance application. Other features include digital tuning, digital squelch and battery-saving sleep mode. A new stereo jack paired with the mono jack adds compatibility with a variety of earphones/headphones. The battery life for the PPA R38 is approximately 50 hours with alkaline batteries and 32 hours with BAT-026-2 1500 mAh rechargeable NiMH batteries.

The CHG 3512 and CHG 3512 PRO multi-unit, drop-in style charger will conveniently store and charge up to 12 Williams Sound R33, R37, CHG 3512 12-Unit chargerR35-8, CHG3502 Two-Unit drop-in chargerR36, R863, RX22-4 receivers, or PPA T36, PPA T46, PFM T36, T863 transmitters over the course of a 16-hour time span. The charger helps keep receivers organized and saves cost on having to replace alkaline batteries. The charger features individual charging LED indicators that blink when batteries are ready. The CHG 3512 PRO includes a convenient portable carry case. A Dual Drop-In Charger, CHG 3502, (right) is also available. The standard version includes a US power supply (120 VAC).
