Shure SLX24/Beta87A at a Glance: Clear transmissions - Simple setup - SLX2/Beta87A handheld microphone/transmitter - SLX4 diversity receiver - Clear transmissions - The SLX sound featured with the SLX24/Beta87A is founded on Shure's patented Audio Reference Companding, a technology which brings more transmission clarity and dynamic range to wireless systems. Unlike traditional wireless companding schemes that are restricted by a fixed compression ratio, this technology utilizes a variable compression ratio. The result is the elimination of wireless artifacts during quiet passages and superior dynamic range. Simple setup - On an operational level, the SLX24/Beta87A system's SLX4 receiver employs features that make setup almost effortless. Utilizing auto frequency selection and auto transmitter setup, the SLX system scans the wireless landscape and identifies a clear channel instantly. Then, guided by an infrared link, at the touch of a button, the transmitter automatically syncs with the receiver. With over 960 operating frequencies across 24MHz of UHF bandwidth, you should be able to quickly and easily set up up to 20 systems in a given location (area dependent).
