General Descri tion
The SR 3054-U is a stereo transmitter with 16 switchable UHF transmission fre-
quencies. It has the same RF characteristics as a radiomicro hone, making multi-
channel frequency selection easy. Its ease of use and excellent mechanical stability
make the SR 3054-U an ideal choice for use in large shows and for touring artists.

3000 Series Monitoring System
The wireless monitoring system, consisting of a UHF stereo rackmountable trans-
mitter and a UHF stereo miniature receiver, has been s eciall y designed for touring,
stage and broadcast use. In addition, the system is also suitable for any a lication
where talkback signals are to be transmitted. With ear hones connected to the
receiver, the musician and/or sound engineer can listen to the stereo audio signal
received – without troublesome cables and monitor s eakers being required.
The risk of feedback is reduced to an absolute minimum as the on-stage micro-
hones can no longer ick u the sound from the now non-existent wedge monitors.
Further advantages are that the foldback mix is now quicker and easier to do
and does not have to be changed when the show changes venue. The system has
su erb audio quality with an increased signal-to-noise ratio due to the inclusion
of “HiDyn stage”, the Sennheiser noise reduction system that has been s ecially
develo ed for stage use.
SR 3054-U and SR 3056-U transmitters
The transmitter of the 3050 wireless monitoring system is available in two versions:
The SR 3054-U is a single stereo transmitter in a 1 U 19” rack housing, the SR 3056-U
consists of two com lete stereo transmitters in the same size housing. Each trans-
mitter has 16 switchable PLL-controlled frequencies and is fully suitable for multi-
channel a lications.
Each transmitter has a stereo/mono selector switch. The multi-function LC dis lay
indic a tes t h e se l e c t ed tr a n smission freq uen cy, t h e A F lev e l (t wo se ar a te b argra h s
for the left and right channel) and the RF out ut ower (in %). The RF out ut
ower and the AF in ut level can be adjusted internall y. The transmitters should
always be used with remote antennas such as the A 2003-UHF assive directional
antenna, the A 1031-U assive omni-directional antenna or the GZA 1036-9
ground lane antenna.
The su lied telesco ic antennas should only be used for a lications where
– good transmission conditions rovided – a transmission system is to be used
without a large amount of installation work. When the transmitters are mounted
into a rack, the telesco ic antennas can be installed at the front of the rack by
using the GA 3030 AM antenna mount.
