WARNING: This apparatus must be grounded.
This product is a safety class 1 product. There must be an
uninterruptible safety earth ground from the main power
source to the product’s AC input. Whenever it is likely that
the protection has been impaired, disconnect the power cord
until the ground has been restored.
ATTENTION: Cet appareil doit être mise à la terre.
Cet appareil est de classe de sûreté 1. Il doit y avoir un
ininterrompable de mise à la terre de sécurité provenant de
la source principale de courant de l’appareil de l’entrée du
courant alternatif. Quand la protection a été affaiblie, débrancher
le fil de courant jusqu’à la mise à terre a bien été réétablie.
To prevent electric shock, do not remove the cover. There are no
user-serviceable parts inside. Internal adjustments are for qualified
professionals only. Refer all servicing to qualified service personnel.
Pour prévenir un choc électrique, ne pas ouvrir le couvercle. Il n’y
aucune pièces de rechanges à l’intérieur. Tout ajustement interne
doit être fait par une personne qualifié seulement. Référez tout
réparation au personnel qualifié.
Prior to use of this product, review all safety markings and instructions.
The ATW-DA49 is a UHF active unity-gain diversity antenna
distribution system that enables one pair of antennas to feed
multiple wireless systems. One ATW-DA49 unit can support up
to four wireless receivers.
A wide-band unit that operates over a nominal 440-900 MHz
range, the ATW-DA49 is designed to complement
Audio-Technica 2000 and 3000 Series wireless systems. It is
also suitable for many other wireless systems (with external
BNC antenna connections) operating within the 440-900 MHz
range.
The ATW-DA49 provides two identical sections, one for each
antenna of a UHF diversity wireless system. Each section in
the unit comprises an antenna input and four isolated receiver
outputs. All RF connectors are BNC-type. Ten BNC-to-BNC RF
interconnect cables are included with the unit.
Antennas can be remotely located from the unit. However, due
to signal loss in cables at UHF frequencies, use the lowest-loss
RF cable type(s) practical for any cable runs over 25 feet. RG-8
is a good choice. Use only copper-shielded cable, not CATV-type
foil-shielded wire. The included ATW-RM1 rack-mount hardware
kit with RF cables and connectors permits front-panel antenna
mounting.
Either passive or active antennas may be used. Both input
jacks offer switchable +12 V DC output on their center pins to
operate Audio-Technica powered antennas or other in-line RF
devices if desired. Up to 100 mA can be drawn from each
antenna input jack.
Four jacks on the rear panel (controlled by the unit's power
switch) provide 12V DC (center positive) to power as many as
four receivers operating on 12 volts at up to 500 mA each.
Included with the unit are four DC cables appropriate for use
with ATW-R3100 or ATW-R2100 (or like-powered) receivers.
The 12-volt supplies for powering receivers are short-circuit
protected. The unit features all-metal construction for extreme
durability and protection from radio frequency interference.
Power Connections
The switching power supply is designed to operate properly
from any AC power source 100-240V, 50/60 Hz without user
adjustment. Simply connect the power supply to a standard AC
power outlet, using only an IEC 320-type input cordset
approved for the country of use.
Front Panel Controls and Functions (Fig. A)
1. POWER SWITCH: Press switch to apply power to unit.
Press again to turn unit off.
2. POWER INDICATOR: The indicator will light when power is
applied.
Figure A Front Panel
The detachable IEC type power input cord supplied is intended for
use in regions with mains voltage in the range of 100–125VAC
only. Use only the furnished power cord that includes the
appropriate NEMA 5-15P/ANSI C73.11 type attachment plug.
For use in geographical areas with mains voltage outside of the
range 100–125VAC, it is necessary for the user to utilize a power
cord rated and configured for operation in their region. Replace the
supplied power cord with a cord rated for correct voltage operation.

Warning/Attention:
To prevent fire or shock hazard, do not
expose this appliance to rain or moisture.
Pour prévenir feu ou choc électrique, ne pas
exposé l’appareil à la pluie ou à l’humidité.

Rear Panel Controls and Functions (Fig. B)
3. CHANNEL “A” ANTENNA INPUT: Attach the “A” antenna
here, or extend it with a low-loss antenna cable. (Antenna
and cable not included.)
4. CHANNEL “A” DISTRIBUTION OUTPUTS: Four jacks
provide RF distribution to receivers operating within the
440-900 MHz range. Each output should be connected to
only one other antenna input. Unused outputs do not
require termination.
5. CHANNEL “B” ANTENNA INPUT: Attach the “B” antenna
here, or extend it with a low-loss antenna cable. (Antenna
and cable not included.)
6. CHANNEL “B” DISTRIBUTION OUTPUTS: Four jacks
provide RF distribution to receivers operating within the
440-900 MHz range. Each output should be connected to
only one other antenna input. Unused outputs do not
require termination.
7. DC OUTPUT JACKS: Provides 12V DC (center positive) at
up to 500 mA from each jack to power receivers. Connect
the included ATW-RDCN cables here to supply 12V DC to
up to four ATW-R2100 or ATW-R3100 (or like-powered)
receivers.
8. DC POWER INPUT: 3-pin header connector for +12V DC
power input.
Active Antenna Power Switch
(Fig. C)
NOTE: ATW-A49 antennas do not require power. If you are
using ATW-A49 antennas, or any passive antennas, leave the
switch in the factory-set OFF position. If you have an antenna
system that requires power (such as an antenna preamp or
booster) you must open the ATW-DA49 assembly and
activate a switch on the circuit board. See Fig. C. (This enables
the antenna distribution system to pass power through to the
antenna.) Current consumption of the preamp or booster should
not exceed 100 mA.
9. The unit is shipped with the switch in the “off” position.
To change the switch to the “on” position, first be certain
the ATW-A49 is not attached to any power source. Next,
use a Phillips screwdriver to remove the four cover screws;
remove the cover; move the switch into the “on” position.
Finally, replace the cover and securely tighten the screws.
Front-mount Antennas–ATW-RM1 Rack Mount Hardware Kit
(Fig. D)
10. The ATW-RM1 rack-mount hardware kit (includes rack ears
and hardware) is provided to permit attachment in a standard
19" audio equipment rack.
11. Antennas may be mounted on the front of the long rack
ear.
The following parts are included in the kit: Long rack ear;
short rack ear; two BNC bulkhead connectors with mounting
hardware; two 34" BNC-to-BNC cables; six rack-mount screws.
Assembling the ATW-RM1 Rack Mount Hardware Kit (Fig. D)
• Remove the nut and lock-washer from each bulkhead
connector. Install the connectors into the from the front
two holes in the long rack ear (see Fig. D). Note that the
flat on the threaded section must be aligned with the flat in
each panel hole.
• Install the lock-washer and nuts (included) over the back of
each bulkhead connector. Secure each connector from the
back with its lock-washer and nut, tightening the nut firmly.
• Connect one end of each provided BNC-BNC cable to the
rear antenna input jacks on the back of the antenna
distribution system amplifier. Attach the other end of each
cable to the back of the BNC bulkhead connectors. Make
certain the bayonet twist-rings are latched on the fully
connectors at both ends.
• Finally, mount the receiver's antennas to each of the BNC
bulkhead connectors.
