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 p12V 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.
