More details on the Sennheiser RS 185
Overview: The Sennheiser RS 185 Digital Wireless headphone system consists of a pair of wireless headphones (HDR 185) and a radio frequency (RF) transmitter (TR 185). The system is designed to enhance the sound of your home audio source, and to give you the freedom to walk around your home with the headphones on.
Wireless Headphones: The HDR 185's wireless headphones feature an open, circumaural (around-the-ear) design. The soft-padded ear cups and headband provide hours of listening comfort. The headphones have controls on the right ear cup: power on/off, volume up, volume down, balance left, balanced right, and level (for selecting manual and automatic level control). With the batteries installed, the HDR 185 headphones weigh approximately 11 ounces.
Analog/Digital Inputs: The RS 185 Digital Wireless headphone system can accept both analog and optical digital input signals. The digital input can only accept PCM signals with a sampling rate of up to 96kHz--it is not compatible with digital bitstream signals. The TR 185 transmitter has analog stereo RCA and digital Toslink input connectors, and includes both analog and digital cables.
TR 185 Transmitter: The system transmits audio on the 2.4 GHz band (2.40 to 2.48 GHz) with 8-FSK Digital modulation. The extended transmission range is approximately 328 feet (100 meters) without obstructions. (Typical performance with obstructions will be somewhat less.) The transmitter is powered by a 9-volt DC power supply/AC adapter. Adapter plugs for the US, Europe, UK, and Australia are provided, allowing for use in other countries. The transmitter doubles as a convenient charging cradle for the headphones. Transmitter dimensions: 4.96"W x 9.264"H x 3.96"D.
Level Control: There are two modes for setting the analog signal input level: Automatic Level Control (ALC) and Manual Level Control (MLC). When set to ALC, the sensitivity of the analog input is adjusted automatically to avoid undesirable volume jumps when switching from one audio device to another, or from one music track to another. You can switch between ALC and MLC by pressing the Level button on the headphones or the transmitter.
Balance Control: The left/right audio balance can be adjusted by pressing the Balance Left or Balanced Right buttons on the headphones until the balance is set to your liking. You can center the balance by pressing both buttons simultaneously.
Rechargeable Batteries: The headphones are powered by the two included "AAA" rechargeable NiMH batteries (1.2V, 820mAh). The batteries fully charge in approximately 8.5 hours, when placed on the top of the transmitter. Battery life is approximately 18 hours of use. Standard, non-rechargeable "AAA" batteries may be used in the headphones, but the headphones must not be placed on the charging cradle.
Auto Power Off: If there is no signal from the transmitter for more than 5 minutes, the headphones automatically switch to standby mode. If the headphones are outside the transmission range or switched to off for more than 5 minutes, the transmitter automatically switches to standby mode.
