11. Protection against Hearing Damage

Do not use any other headphones than the IP1 miniature in-ear
phones specifically designed by AKG for the IVM1. This is the
only way to ensure that the two-stage protection system will
function properly. This system comprises a limiter integrated in the
transmitter and a clipping diode at the phones output on the SPR1
receiver.
If, due to malfunction, the volume shoud rise to a level that may
damage your hearing, the built-in limiter will instantly reduce the
level automatically.
Using any in-ear phones other than those recommended by AKG
may defeat this protective function! AKG therefore declines any
liability whatsoever.
Warning: Listening at excessive volume levels over an extended
period of time may cause severe damage to your
hearing.

12. Cleaning

To clean the surfaces of the transmitter, receiver, and earmolds, use
a soft cloth moistened with methylated spirits or alcohol.

13. Accessories

13.1. RMU11 (Fig. 10)
Rack Mount Unit accepting one SST1 and AC power adapter.
Provides an alternative antenna socket on the front panel.
13.2. RMU 12 (Fig. 11)
Rack Mount Unit accepting two SST1 transmitters and their AC
power adapters. Provides alternative antenna sockets on the
front panel.
13.3. SRA1 (Fig. 12)
Remote antenna for optimum antenna placement independent
of the transmitter location. Particularly recommended for use
with rack mounted SST1 transmitters because it is often difficult
to place a rack where it would ensure optimum UHF propaga-
tion.

13.4. Other Recommended Products

Logitek PR10 Input Extender (Fig. 14)
In a professional multichannel system, the PR10 Input Extender
allows the same signal to be fed to two IVM1 systems simul-
taneously.
One IVM1 functions as a backup system that can be cut in
immediately if the other system should fail.

Conex AS 101 Audio Switcher &
AS 401 Remote Control (Fig. 14)
The AS 101 allows the monitor engineer to listen to the monitor
mix for each artist separately.
All mixes can be selected at the push of a button either on the
AS 101 itself or on the AS 401 remote control.
Suhner (Fig. 13)
Suhner makes antenna cables of extremely high quality. Thanks
to their extermely low attenuation, these allow longer cable runs
than standard types with almost zero signal loss.

Directional Antenna (Fig. 15)
For applications where the mixing position is more than 200 ft.
or 230 ft. away from the stage, we recommend to use direc-
tional antennas, for instance, the Hirschmann model shown in
fig. 15. These antennas will increase the range of the transmit-
ter without the need for extremely long antenna cables. Ask
your AKG dealer for more information.
