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.

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.

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.

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.

AEW-DA550C and AEW-DA660D Installation and Operation

The AEW-DA550C and AEW-DA660D are UHF active unity-gain diversity antenna distribution systems. Identical in all other respects, the AEW-DA550C operates over a nominal 540-565 MHz range, while the AEW-DA660D operates over a nominal 655-680 MHz range. These units are designed to complement wireless systems operating in the Audio-Technica “C” Band (541.500 - 566.375 MHz) or “D” Band (655.500 - 680.375 MHz), as well as other wireless systems operating in the same frequency ranges.

For conciseness, only the AEW-DA550C model is mentioned in the following instructions. All information in this manual applies to both models, except as noted.

The AEW-DA550C 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 AEW-DA550C units. All RF connectors are BNC-type. Ten BNC-to-BNC RF interconnect cables are included with the unit.

Front Panel Controls and Functions (Fig. A)

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 offer switchable +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 up to 500 mA each. Included with the unit are four DC cables appropriate for use with ATW-R310 (or like- powered) receivers.

The 12-volt supplies for powering receivers and in-line devices are short-circuit protected.

The unit features a steel case with steel-reinforced front panel and rear rack-mount supports for extreme durability. An included set of RF cables and connectors permits front-panel antenna mounting.

1.POWER SWITCH: Press switch to apply AC power to unit. Press again to turn unit off.

2.POWER INDICATOR: Shortly after power is applied, the indicator will light.

3.FRONT-MOUNT ANTENNAS: Cables and panel connectors are included to permit attaching antennas at the front panel.
