ARCHITECT’S
SPECIFICATIONS
The device shall be a dual channel stationary stereo transmitter for use with two
companion stereo receivers as part of a
high reliability dual channel stereo wireless
radio frequency transmission system. Each
channel of the stationary transmitter shall
provide the following features and performance: The stationary stereo transmitter
shall operate within a RF frequency range
of 516 – 865 MHz in 20 fixed frequency
banks and 6 user banks with a maximum
of 32 presets with a switching bandwidth
of maximum 75 MHz tunable in 25 kHz
steps; carrier frequencies shall be maximum 3000. Frequency stability shall be
±10 ppm. Nominal/peak deviation shall be
±24 kHz/±48 kHz. A compander feature
shall be included and shall be Sennheiser
HDX system. The transmitter shall include
MPX pilot tone (frequency / deviation) of
19 kHz / ±5kHz. Audio frequency response
shall be 25 – 15,000 Hz; total harmonic
distortion (THD) shall be <0.9 %. Audio
frequency input level shall be +22dBu
(maximum, balanced). Signal-to-noise
ratio shall be > 90 dB.

Aside from being designed as a twin transmitter, SR 2050 is identical to SR
2000, and like its single counterpart, it is also network compatible. In other
words: Through the Ethernet connections, you can monitor and control SR 2050
from your Mac or PC using Sennheiser’s Wireless Systems Manager software.
You can also easily link other network-compatible components from other
Sennheiser series.
