Overview: The Sennheiser RS 195 Digital Wireless
headphone system consists of a pair of wireless headphones (HDR 195) and a radio
frequency (RF) transmitter (TR 195). The system is designed to enhance the sound
of your TV or your home audio source, and to give you the freedom to walk around
your home with the headphones on.
Wireless Headphones: The HDR 195's wireless headphones
feature a circum-aural (around-the-ear), closed design to significantly reduce
background noise. 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, and mode. With the batteries installed, the HDR
195 headphones weigh approximately 12 ounces.
TR 195 Transmitter: The transmitter connects to your
television's or audio system's audio output via the included 3.5mm cable or
optical digital cable (supports 2ch PCM only). You can switch between the two inputs with a provided
toggle switch. The audio is transmitted 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.
Listening Modes: The RS 195's transmitter features three
listening modes for tailoring the sound to your individual preferences. By
pressing the Mode button on the transmitter or the right ear cup on the
headphones, you can select Normal, Speech (for clearer dialogues), or Music (for
increased dynamic range for music).
Personal Hearing: The RS 195 wireless headphone system can
be used to enhance your hearing. The Personal Hearing feature offers seven
hearing profiles, each with different sound optimizations and hearing profiles.
You can select the profile that works best for your personal hearing experience,
using the rotary dial on the front of the transmitter (marked A through G), or
pressing the Mode button on the headphone's right ear cup.
Balance Control: The left/right audio balance can be
adjusted by turning the rotary balance control on the front of the transmitter.
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.
