Prior to use of this product, review all safety markings and instructions.
The ATW-DA600 is a UHF active unity-gain antenna
distribution system operating over the 656-680 MHz range.
The ATW-DA700 is identical in all respects to the ATW-DA600
except for its operating frequency range: 728-752 MHz.
The ATW-DA600 provides two identical sections, one for each
antenna of a UHF diversity wireless system. Each section
in the unit comprises an antenna input, four bandpassed,
isolated receiver outputs, and a bandpassed “cascade”
directional coupler to supply signal to additional ATW-DA600
units. 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.
Either passive or active antennas may be used. Both antenna
input jacks provide +12V DC output on their center pins to
operate Audio-Technica powered antennas or other in-line RF
devices, if desired. Up to 250 mA can be drawn from each
antenna input jack.
Additionally, four jacks on the rear panel provide 12V DC
(center
positive
) to power as many as four receivers operating
on 12 volts at 350 mA each. Included with the unit are four
polarity-inverting DC cables appropriate for use with ATW-R73
(or like-powered) receivers.
The 12-volt supplies for powering receivers and in-line devices
are short-circuit protected.
The unit’s switching power supply is designed to operate
properly from any AC power source 100-240V, 50/60 Hz
without adjustment. Simply connect to a standard AC power
outlet, using an IEC input cordset approved for the country of
use. The unit normally is supplied with a 120V cordset.
The unit includes pre-installed rack adapters (“rack-mount
ears”) for mounting in a standard 19" rack. (#10-32 rack-
mounting screws are not included.) If rack mounting is not
required, the adapters may be removed by simply taking out
the three screws holding each adapter in place. Save the
adapters and screws for possible future use.

3. AC POWER: IEC-type connector for 100V to 240V AC power input. No adjustment for mains voltage/frequency is necessary;
connect an IEC input cordset approved for the country of use.
4. FUSE HOLDER: To check or replace fuse, disconnect the AC cordset and carefully remove the holder with a small
screwdriver. Replace fuse only with the same type 250V 2.5A.
5. DC OUTPUT JACKS: Provides 12V DC (center
positive
) at up to 350 mA from each jack to power receivers. Connect
the included ATW-RDCP polarity-inverting cables here to supply 12V DC (center
negative
) to up to four ATW-R73
(or like-powered) receivers.
6. CHANNEL “B” ANTENNA INPUT: Attach the “B” antenna here, or extend it with a low-loss antenna cable. (Antenna and
cable not included.) The antenna input jack also provides +12V DC output on its center pin at up to 250 mA to power
in-line RF devices.
7. CHANNEL “B” CASCADE OUTPUT: Directional coupler provides RF output to additional distribution systems operating in the
same frequency band. Each cascade output should be connected to only one other unit input, and no more than three
distribution units total should be “daisy-chained.”
8. CHANNEL “B” DISTRIBUTION OUTPUTS: Four jacks provide RF distribution to receivers operating in the same frequency
band. Each output should be connected to only one other antenna input, without “daisy-chaining.” Unused outputs do not
require termination.
9. CHANNEL “A” ANTENNA INPUT: See #6 above.
10. CHANNEL “A” CASCADE OUTPUT: See #7.
11. CHANNEL “A” DISTRIBUTION OUTPUTS: See #8.
Accessories Included 1 120V power cordset, 10 BNC-to-BNC
1.5' interconnect cables, 4 ATW-RDCP
DC polarity-inverting 1.5' interconnect
cables, 2 rack-mount adapters
(installed), 4 self-adhesive feet.
Optional Accessories ATW-RDCN: Non-polarity-inverting DC
interconnect cables (set of four). For
use with receivers that have center
positive
DC jacks.
ATW-RA1: Rack-mount antenna kit
brings antenna inputs to the front of
unit for ease of setup, or when unit
is enclosed in a metal rack. Includes
a pair of adjustable-length antennas
suitable for UHF or VHF use.
