Applications; Conformity And Approval - Monacor International JTS IN-164R /2 Mode D'emploi

damage will be accepted if the units are used for
other purposes than originally intended, if they
are not correctly connected or operated, or if they
are not repaired in an expert way.
If the units are to be put out of operation
definitively, take them to a local recycling
plant for a disposal which is not harmful to
the environment.

3 Applications

Combined with the transmitter IN-264TB / 2 or
IN-264TH / 2 from JTS, the UHF PLL receiver
IN-164R / 2 creates a wireless audio transmission
system ideally suited for professional stage ap pli-
cations. The receiver uses the diversity technology:
The signal transmitted is received by two antennas
placed at a distance from each other and then
checked for its quality. The signal with the highest
signal quality will be used.
The transmission system operates in the fre-
quency range 740 – 776 MHz. Six channel groups
with preset channels in different numbers (22 max.)
are available. Frequency matching is very easy:
Via a radio signal, the receiver will set the trans mit-
ter to the same transmission frequency (REMO-
SET function).
For installing the receiver into a rack (482 mm/ 19"),
the bracket DR-900SET which is able to accom-
modate two receivers IN-164R / 2 is available as an
accessory from JTS. The bracket requires a height
of 1 RS (1 rack space = 44.5 mm) in the rack.

3.1 Conformity and approval

Herewith, MONACOR INTERNATIONAL declare
that the unit IN-164R/2 is in accordance with the
basic requirements and the other relevant regula-
tions of the directive 1999 / 5 / EC. The declaration of
conformity is available on request from MONACOR
INTERNATIONAL. The receiver is licence-free
and generally approved for operation in EU and
EFTA countries.
4 Connection
1) Insert the two antennas (1) provided into the
antenna jacks ANT. 1 and ANT. 2 (15). Place the
antennas in a vertical position.
Hint: To increase the range and the interference re -
sistance, use two antenna amplifiers UB-900 / 2 (incl.
antennas) available as accessories instead of the
antennas provided. The amplifiers are supplied with
power via the antenna jacks of the receiver.

2) For connection to a microphone input or highly
sensitive line input of the subsequent unit (e. g.
mixer, amplifier), use one the two balanced
audio outputs:
– XLR output (11); if required, attenuate the
signal level of this output by 20 dB with the
toggle switch OUTPUT LEVEL (10) [position
MIC.].
– 6.3 mm output jack (9); for connection to an
unbalanced input, use the cable provided
3) Connect the power supply unit provided to the
power supply jack (14) and to a mains socket
(230 V~/50 Hz). To prevent accidental discon-
nection of the low voltage plug, lead the cable of
the power supply unit around the hook (13) for
strain relief.
5 Operation
1) Do not switch on the transmitter of the system
yet; switch on the receiver first: Set the on/off
switch (8) to ON. When the unit is switched on,
the ring around the REMOSET button (3) lights
up. After briefly indicating the identification num-
ber ( chapter 5.1.3), the display (4) shows:
– the group

the group (overview of groups and channels
table on page 24)
– the indication MUTE (f)
The muting function will be activated when no
radio signal is received from the transmitter
on the transmission frequency adjusted,
when the signal received is poor or when the
transmitter is muted (possible for transmitter
IN-264TH/2 only).
2) Before switching on the transmitter, set the
receiver to a free and interference-free trans-
mission frequency
transmission frequency has been set and the
reception indication RF (a) shows a radio signal
(one or several segments of the indication are
displayed), select a different frequency.
3) Switch on the transmitter, check its settings
( instruction manual of the transmitter), then
set it to the same transmission frequency via the
REMOSET function according to chapter 5.2.
When the transmitter and the receiver have
been set to the same frequency, the muting
function is deactivated; the indication MUTE (f)
disappears. One of the indications
displayed to show which of the antennas (1) re -
ceives the more powerful radio signal. The indi-
cation RF (a) shows the reception quality: the
(g) and the channel (h) from
chapter 5.1.1. When the
