2 Safety Notes

The units (receiver and power supply unit)
correspond to all relevant directives of the EU
and are therefore marked with
WARNING The power supply unit uses
•
The units are suitable for indoor use only .
Protect them against dripping water, splash
water and high air humidity . The admissible
ambient temperature range is 0 – 40 °C .
•
Do not place any vessels filled with liquid,
)
e . g . drinking glasses, on the units .
•
Immediately disconnect the power supply
unit from the mains socket if
1 . the receiver or the power supply unit is
visibly damaged,
2 . a defect might have occurred after a
unit was dropped or suffered a similar
accident,
3 . malfunctions occur .
In any case the units must be repaired by
skilled personnel .
•
For cleaning only use a dry, soft cloth; never
use water or chemicals .
•
No guarantee claims for the units and no
liability for any resulting personal damage
or material 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 definitely, dispose of the
units in accordance with local reg-
ulations .
3 Applications
Combined with up to four wireless micro-
phones, the 4-channel receiver TXS-646
creates a wireless audio transmission system
ideally suited for conferences as well as for
musicians and live performances on stage .
The True Diversity* receiver uses the UHF
range 672 .000 – 696 .975 MHz .
* True Diversity technology: The signal sent from
the wireless microphone is received by two anten-
nas and amplified in two separate receiver sections .
The signal of the highest power is then processed .
Frequency setting via the ACT function (Auto-
matic Channel Targeting) is a most convenient
feature: Simply press a button to set the wire-
less microphone via IR signal to the channel
selected on the receiver .

Leave servicing to skilled
personnel; inexpert handling
may result in electric shock .

4 Operation

4.1 Setting up, connecting and
switching on the receiver
Prior to connecting / disconnecting, switch off
all units concerned .
1) The receiver is designed for installation into
a rack (482 mm /19"); however, it can also
be placed on a table . For installation into a
rack, two rack spaces (89 mm) are required .
2) Insert the two receiving antennas (8) sup-
plied into the antenna jacks ANT A and
ANT B (10) . To lock the antennas, turn
the knurled ring of the plug clockwise to
the stop . Then place the antennas into a
vertical position . To remove the antennas,
turn the ring counter-clockwise .
The mounting brackets TXS-100BNC
can be used to install the antennas outside
the rack, e . g . if there is not enough space
for the antennas or if other units in the
rack shield the radio waves . The mounting
