SA1523H - Multi-Channel Infrared Receiver user selectable to 2.3 MHz, 2.8 MHZ or 95 kHz

SA1523H Front | SA1523H Bottom
Sound Associates manufactures two types of wireless stethoscope-style headset receivers designed for professional applications: the SA1521H (single-channel) and SA1523H (3-channel). Our headsets are equipped with a sophisticated receiving circuitry with multiple receiving diodes to increase sensitivity. Also, high-performance micro speakers are utilized to give the user remarkable audio reproduction.

The SA1520 series headsets are compatible with most infrared transmission systems currently in use. They are designed with a new industrial-strength chassis for added durability in commercial applications. Its advanced mechanical design ensures years of trouble-free use, while making the headset comfortable to wear.

The SA1523H is a 3-channel receiver, switchable between 2.3 MHz, 2.8 MHz and 95 kHz. The receiver is worn under the chin, stethoscope-style and is powered by a light weight lithium polymer rechargeable battery, designed especially for the Sound Associates’ line of receivers.
