ARCHITECT’S
SPECIFICATIONS
The device shall be a single channel, true
diversity (two tuners per receiver channel)
stationary receiver for use with a companion
transmitter as part of a high reliability true
diversity wireless radio frequency transmission
system. The stationary receiver shall operate
within a RF frequency range of 516 – 865 MHz
in 20 fixed frequency banks and 6 user banks,
each with a maximum of 64 presets with a
switching bandwidth of maximum 75 MHz
tunable in 25 kHz steps; carrier frequencies
shall be maximum 3000. Squelch threshold
shall be defeatable (off) or adjustable from 5 –
25 dBµV in 2dB steps. Nominal/peak deviation
shall be ±24 kHz/±48 kHz. Intermodulation
spacing shall be ≥75dB. A compander feature
shall be included and shall be Sennheiser HDX
system with pilot-tone squelch (switchable).
Sensitivity shall be < 2.0 µV for 52 dBArms S/N
with HDX engaged at peak deviation. Adjacent
channel rejection shall be ≥80dB (typical);
blocking shall be ≥80dB. Audio frequency res-
ponse shall be 25 – 18,000 Hz; total harmonic
distortion (THD) shall be <0.9%.

Hiding underneath the sturdy 19-inch metal housing of the stationary receiver
is highly advanced professional transmission technology. As with all compo-
nents of the 2000 series, with the EM 2000 you can use five windows of up
to 75 MHz in the UHF range. 20 channel bands with up to 64 presets and 6
channel bands each with up to 64 user-programmable channels are available.
Each transmitter can be synchronized quickly and easily using infrared. The
transmitter can be connected to networks via its Ethernet socket and can be
monitored and controlled remotely from the Mac or PC using the Sennheiser
Wireless System Manager software.
