Toa Electronics WS-5325H-AM Wireless Cardioid Headset Microphone System (M1: 506 to 538 MHz)

The WS-5325H-AM from TOA is a professional UHF wireless headset microphone system designed for reliable speech and general-purpose sound reinforcement applications. The system combines the WM-5325-AM bodypack wireless transmitter and WH-4000H cardioid headset mic with the WT-5810-AM diversity desktop wireless receiver, delivering stable hands-free wireless performance for venues ranging from conference rooms and houses of worship to multi-purpose halls and auditoriums.

The lightweight and ergonomic WM-5325-AM bodypack transmitter features a locking 3.5mm input connector, allowing it to work with a wide variety of lavalier and headset microphones. This system configuration includes a lightweight WH-4000H electret-condenser headworn microphone with a cardioid pickup pattern that focuses audio capture on the talent, reducing bleed from other sources and helping to reduce feedback when sound reinforcement equipment is deployed. Power for the transmitter is supplied by either a single AA battery or an optional WB-2000 Ni-MH rechargeable battery. When used with the optional BC-5000-2 battery charger and WB-2000 battery, up to approximately 13 hours of continuous operation is available.

The included WT-5810-AM receiver is a PLL-synthesizer controlled, double superheterodyne diversity tuner designed for dependable UHF wireless operation. Space diversity operation automatically selects the stronger of two antenna signals for processing, helping to maintain consistent reception. A built-in compander noise reduction circuit minimizes the influence of ambient RF noise, while automatic frequency scanning simplifies setup. The system supports operation of up to 16 simultaneous receivers.

Front-panel indicators on the receiver provide clear visual status of RF reception, transmitter battery condition, and AF peak levels. User controls include channel selection keys with channel number display, a 7-step adjustable squelch, RF check function, and output volume control. Rear-panel connections include balanced XLR and unbalanced 1/4" audio outputs, along with an audio mixing input and output for flexible system integration. The receiver features a compact, portable desktop design and is powered via an included AC adapter.
