Combining superior construction with artistic and technical freedom, the Sennheiser Single Channel Stereo IEM System A (516 - 558 MHz) is built for professional use, yet affordable enough to fit the budget of even a modest size venue, post-production house, audio studio or mobile broadcast setup. The system is both rugged and reliable; it was designed to be portable, rack-mountable and road dependable. This particular Single Channel Stereo IEM System was designed specifically for the 516 - 558 MHz frequency range and features Sennheiser's wireless SR 2000-XP IEM Audio Transmitter and EK 2000 IEM Portable Monitoring Diversity Receiver. The system also comes with four sets of matching Sennheiser IE4 Earphones for Wireless Monitor Applications.

The heart of Sennheiser's Single Channel Stereo IEM System is the reliable, versatile and durable SR 2000-XP Wireless Monitoring / Audio Sound Transmitter. Road-tested and ultra-dependable, the wireless transmitter is housed in a rugged 1RU rack-mountable metal chassis. It features a substantial frequency bank system with 26 banks and each one supports 32 selectable channels. With such a sweeping span of frequency choices, users should have no problem finding a pristine, clear signal that's free from interference. Plus, for added flexibility, the SR 2000-XP even supports switchable radio frequency (RF) output powers with 10, 30, 50 and 100 mW options. This combination of range, durability and versatility makes it an ideal solution for a variety of in-ear monitoring (IEM) applications ranging from the concert-hall stage and professional studio, to the back of a mobile production van and everywhere in between.

The receiving end of the SR 2000-XP is the Sennheiser EK 2000-IEM Diversity Receiver. It's intended for use with their monitoring systems and is completely compatible with any of the Sennheiser SK series transmitters. Together the transmitter and receiver provide reliable audio monitoring during stage performances, broadcasts and more. Plus, the EK 2000-IEM features adaptive diversity reception to reduce drop-outs. It's equipped with six banks of up to 32 tunable channels as well, and runs on two 1.5 V AA batteries. Acting as an extended antenna for the accompanying receiver, the IE 4 In-Ear Earphones provide excellent sound quality and comfort with a wide dynamic range. They include three sizes of interchangeable ear tips, which help deliver the best fit for comfort and sound isolation, as well as increased bass. Small and mighty, they are an integral part of the Sennheiser Single Channel Stereo IEM System.
