About the Koss JR900

Koss JR900 is a RF (Radio Frequency) Wireless Stereophone System. The JR900 stereophone system operates on a 900MHz radio frequency band, one of the highest power band for cordless stereophones available on the market. The JR900 consists of a high quality, battery operated stereophone, the RF transmitter and an AC adapter. Utilizing a radio signal, the JR900 allows the listener to move freely from room to room and outdoors without the need for additional transmitters or experiencing signal breakup.

The signal can be transmitted through walls, ceilings and floors and is not affected by bright sunlight. Listeners can roam freely over 70,000 square feet within the signal. Finish cleaning the attic while keeping an ear on your favorite soap operas. Work out in the garden or garage while tuning into the Sunday afternoon football games. Or just lounge around on the deck on a summer evening with a live symphony broadcast. Combing the Sound of Koss with the latest in RF technology, the JR900 is Koss' answer to music lovers' need for true stereo and cordless freedom.

JR900 transmitter, the heart of the JR900 system, provides 5 stereo transmit channels for freedom from interference or use from multiple audio or video sources. The 5 channel capability of the JR900 transmitter allows the listener to switch between channels to find the cleanest, clearest reception if interference occurs. Pressing the channel select control on the stereophone ear cup locks the stereophone onto a chosen channel. This 5 channel capability also makes the JR900 perfect for commercial applications as well as home use multi screen movie theaters, multi-cultural events, museums, educational programs. Hooking up additional transmitters to separate audio sources, the listener can tune into different audio programs on the JR900 stereophones, simply by pressing the channel select control on the stereophone earcup.

No other RF stereophone system on the market delivers the exceptional sound reproduction and extended frequency response of the JR900 stereophones. Neodymium iron boron magnet structures and mylar diaphragms only 16 microns thick deliver crisp highs and amazing bass response. Oxygen-free copper voice coils transmit the clearest signal possible in a dynamic stereophone. The JR900 has a frequency response of 20-20,000Hz to deliver the deep bass and treble clarity known as the Sound of Koss. Circumaural leatherette ear cushions enclose the ear for maximum isolation and deep bass. An adjustable, padded, vinyl covered headband fits any head size and shape for the most comfort during extended listening.

A dual volume control on the stereophone ear cup provides convenient level and balance adjustment for a customized sound. A microchip in the stereophone circuit automatically locks the transmitter signal onto the selected channel to prevent drift between audio sources.
