SST 4
The SST 4 is the first stereo transmitter ever to combine all the features
required for professional in-ear monitoring in a single, compact device.
The SST 4 allows the input signal to be processed individually to meet the
requirements of both the artist and the sound system environment. An integrated
dbx compressor, many EQ settings, and optimized binaural room simulation
algorithms provide outstanding high performance signal processing flexibility.
Preprogrammed frequency preset banks ensure an easy and reliable startup.
Up to 14 intermodulation-free channels* can be used within a 30 MHz wide
UHF band. In addition, up to 1200 frequencies can be selected manually. These features allow the IVM 4 to be used together with any AKG WMS 400 or WMS 4000
wireless microphone system. The SST 4 lets you adjust the RF output
within the approved range, which is particularly important when the in-ear monitor
system is used together with a complex wir eless microphone system.
This allows optimum system matching for improved reliability.
A complete line of accessories is available for multichannel applications.
A large, backlit display gives a clear picture of all important settings and levels.
When used in dark environments, the brightness of the display can be reduced.
The input signal level is digitally adjustable within a range of ±20 dB. A pair of
Loop Out jacks carries the unprocessed input signal for daisy-chaining several SST 4s.
Unique integrated signal processing for a natural listening experience and a
complete set of inputs and outputs make the SST 4 an ideal tool for professional
applications.

The SPR 4 bodypack receiver features a rugged die-cast magnesium case.
Auto Setup and Environment Scan functions for finding clean frequencies
make setting up extremely easy. The 30 MHz bandwidth allows manual
selection of 1200 frequencies or the system chooses from preprogrammed
frequency preset banks.The SPR 4 provides a backlit display and jog control
for ease of use. The display indicates the received signal strength and battery
status along with other parameters. Integrated charging contacts allow the
optional BP 4000 battery pack to remain inside the receiver whilst being
charged on the CU 4000 charger (optional).The BP 4000 will be charged to
capacity in only one hour, and can power the SPR 4 for about seven hours.
The IP 2 earphones connect to the SPR 4 bodypack receiver. These high quality
earphones provide a wide-range sound with sharply contoured bass reproduction
as well as excellent isolation to suppress high ambient noise levels encountered,
e.g., on a loud concert stage. An integrated sliding cable tie and the supplied
soft-rubber earmolds in three different sizes enable the earphones to adapt to
every shape of ear and head.
The IP 2 earphones are included in the IVM 4 Sets and in the SPR 4 Sets and
are also available single packed.
The only control the artist needs to operate is an ergonomically shaped volume
control with integrated on/off switch. Placed in the center of the SPR 4 top
panel, the volume control with its clearly discernible detents can be operated
intuitively even if it is positioned outside the user's field of vision.
An Individual mix function allows a personalized monitor mix to be set up even
where only a small sound system with no separate monitor mixer is available.
To accommodate the individual preferences of users, the SPR 4 has been
designed to drive a large number of different types of earphones.

SRA 2 W
The SPC 4 wideband antenna combiner allows the set up of large wireless
in-ear monitor systems. A single antenna combiner enables the output signals
of up to four SST 4 stereo transmitters to be combined into one composite
antenna signal. Besides this antenna management function, the SPC 4 powers
the SST 4 stereo transmitters connected to it, thus reducing the number of
plug-in AC adapters in the rack.
You can use either an SRA 2 W passive directional antenna or an RA 4000 W
passive omnidirectional antenna for the wireless monitor system.
The four-channel in-ear monitor system shown in the example drawing
occupies only 3 U of rack space.
