Frequently Asked Questions - ATW-DA49 Audio-Technica

What is the ATW-DA49 used for?

The ATW-DA49 is a UHF active antenna distribution system that allows one pair of antennas to feed up to four wireless receivers, simplifying setup in multi-channel systems.

What frequency range does the ATW-DA49 support?

It operates over a nominal 440-900 MHz range, compatible with many UHF wireless systems including Audio-Technica 2000 and 3000 Series.

Can I use passive antennas with the ATW-DA49?

Yes, passive antennas work fine. The internal antenna power switch must be OFF for passive antennas. Active antennas requiring +12V DC can be powered by enabling the switch.

How do I power receivers from the ATW-DA49?

The rear panel has four DC output jacks providing 12V DC (center positive) at up to 500 mA each. Use the included DC cables to connect to compatible receivers like ATW-R2100 or ATW-R3100.

What type of power cord do I need?

The unit includes an IEC 320/C14 cord for 100-125V AC regions. For 200-240V AC regions, use a cord rated for the local voltage and equipped with the appropriate plug.

Can I rack mount the ATW-DA49?

Yes, the included ATW-RM1 kit allows mounting in a standard 19-inch rack. The long rack ear also supports front-mounted antennas via BNC bulkhead connectors.

How many receivers can one ATW-DA49 support?

It supports up to four receivers, with each of the two antenna channels providing four isolated outputs.

What cable should I use for long antenna runs?

For runs over 25 feet, use low-loss RF cable such as RG-8 with copper shielding. Avoid CATV-type foil-shielded cable to minimize signal loss.

Is the ATW-DA49 grounded?

Yes, it is a safety Class 1 product and must be connected to an earthed mains outlet. The detachable power cord provides the ground connection.

How do I enable the antenna power output?

Open the unit by removing the four cover screws, locate the switch on the circuit board (Fig. C), and set it to ON. Ensure passive antennas are not connected when enabling this feature.

InstallationandOperation

Prior to use of this product, review all safety markings and instructions.

CAUTION RISK OF ELECTRIC SHOCK DO NOT OPEN

AVIS RISQUE DE CHOC ÉLECTRIQUE NE PAS OUVRR

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.

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.

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.

ATW-DA49InstallationandOperation

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.

1. CHANNEL "A" ANTENNA INPUT: Attach the "A" antenna here, or extend it with a low-loss antenna cable. (Antenna and cable not included.)
2. 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.
3. CHANNEL "B" ANTENNA INPUT: Attach the "B" antenna here, or extend it with a low-loss antenna cable. (Antenna and cable not included.)
4. 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.
5. 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.
6. DC POWER INPUT: 3-pin header connector for +12V DC power input.

Figure B Rear Panel

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.

Assembling the ATW-RM1 Rack Mount Hardware Kit (Fig. D)

• Remove the nut and lock-washer from each bulkhead connector. Install the connectors from the front into the 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 fully latched on the connectors at both ends.
• Finally, mount the receiver's antennas to each of the BNC bulkhead connectors.
