Introduction; Precautions; Sst1 Stereo Stationary Transmitter; Controls - AKG IVM 1 User Instructions

1. Introduction

Thank you for selecting the IVM1 Individual Virtual Monitor System
from AKG. Please take the time to read through this Manual. It
contains information on how to make optimum use of your equip-
ment. We wish you many successful productions!

2. Precautions

Power connector and ground: This equipment may require
the use of a different line cord, attachment plug, or both,
depending on the available power source at installation. If the
attachment plug needs to be changed, refer servicing to quali-
fied service personnel.
WARNING: If the ground is defeated, certain fault conditions in
the unit or in the system to which it is connected can result in
full line voltage between chassis and earth ground. Severe
injury or death can then result if the chassis and earth ground
are touched simultaneously.
Heat: Do not place the equipment near heat sources such as radi-
ators, heating ducts, or amplifiers, etc. and do not expose it to
direct sunlight, excessive dust, moisture, rain, mechanical vibra-
tions, or shock.
Water and moisture: Appliance should not be used near
water (e.g. near a bathtub, washbowl, kitchen sink, laundry
tub, in a wet basement, or near a swimming pool, etc). Care
should be taken so that objects do not fall and liquids are not
spilled into the enclosure through openings.
Power sources: The appliance should be connected to a
power supply only of the type described in the operating
instructions or as marked on the appliance.
Grounding or polarization: Precautions should be taken so
that the grounding or polarization means of an appliance is not
defeated.
Power cord protection: Power supply cords should be rout-
ed so that they are not likely to be walked on or pinched by
items placed upon or against them, paying particular attention
to cords at plugs, convenience receptacles, and the point
where they exit from the appliance.
Servicing: To reduce the risk of fire or electric shock, the user
should not attempt to service the appliance beyond that
described in the operating instructions. All other servicing
should be referred to qualified service personnel.
Multiple-input voltage: This equipment may require the use
of a different line cord, attachment plug, or both, depending
on the available power source at installation. Connect this
equipment only to the power source indicated on the equip-
ment rear panel. To reduce the risk of fire or electric shock, refer
servicing to qualified service personnel or equivalent.
3. SST1 Stationary Stereo Transmitter
The SST1 (fig. 1) is a stationary transmitter operating in the high-
band UHF range between 766 MHz and 952 MHz. It is avail-
able with one of 20 different standard sets of frequencies (refer to
section 15). Each Frequency Set covers a subband up to 20 MHz
wide and a dedicated menu lets you select one of up to 16 carrier
frequencies within the subband.
The SST1 is software controlled for easy selection and adjustment
of carrier frequencies and all other SST1 functions including IVA
parameters (refer to section 7.5).
The integrated compander is always active and not switchable to
ensure optimum transmission quality at all times.

4. SPR1 Stereo Bodypack Receiver

The SPR1 (fig. 6) is a stereo bodypack receiver operating in the
high-band UHF range between 766 MHz and 952 MHz. Like the
SST1, the SPR1 is available with one of 20 different standard sets
of frequencies (refer to section 15). Each Frequency Set covers a
subband up to 20 MHz wide and a rotary selector switch (6e) lets
you select one of up to 16 carrier frequencies within the subband.
