DW-11/DW-22 RECEIVERS

RECEIVER OPERATION

1. Rack mounting The Receivers
   There are 2 options available for rack mounting the DW-11/DW-22 receivers: singly or side-by-side with another DW-11/DW-22 Series receiver. A single DW-11 or dual DW-22 receiver can be rack mounted with the optional RMT-1KUD rack tray.
   Note: Do not mount the receiver in a rack directly above an amplifier or other source of high heat – this could degrade the performance of the DW-11/DC-22. Always ensure adequate airflow and heat dissipation in any rack configuration.

2. Powering The Receivers
   Plug the AC/DC ADAPTER provided into the DC INPUT JACK (9) on the back of the receiver. Then plug the power supply into an AC outlet.
   Note: Any 13.5V DC regulated source with 400mA capability can also be used.] Press the POWER SWITCH (2) once to turn on the receiver. The POWER ON LED (1) will now light and the receiver is operational.

3. Antennas
   The DW-11/ DW-22 receivers are supplied with ATTACHED ANTENNAS (10). As these antennas are rear mounted, position them in the rack so the antennas can be adjusted fully to obtain maximum range. Optimal antenna position is 45 degrees from the receiver (at 90 degrees from each other). For maximum range, it is always best to maintain a line-of-sight (no obstructions) between the receiver antennas and the transmitter at all times whenever possible.

4. Connecting the Audio Output
   The DW-11 and DW-22 receivers provide both a fixed Mic level BALANCED XLR (7) AUDIO OUTPUT and an adjustable line level UNBALANCED LINE/MIX 1/4” jack (8) AUDIO OUTPUT. Both ¼” and XLR outputs can be used at the same time. VOLUME CONTROL (6) is for UNBALANCED LINE/MIX 1/4” jack (8) AUDIO OUTPUT only (p 6).

5. Microphone Connection
   Either the BALANCED XLR (7) or the UNBALANCED LINE/MIX OUT1/4” (8) can be used. The BALANCED XLR (7) audio output is set at a non-adjustable microphone level, similar to hardwired Mic levels. Adjust volume level from your amplifier or mixing board. Plug an XLR connector into the XLR output socket on the rear of the unit and plug the other end into your amplifier or mixing board. Make sure the phantom power on your mixing board is turned off and the volume is turned down when making connections. To use the 1/4” UNBALANCED LINE/MIX OUT(8) socket, follow the instructions for connecting (above), except start the receiver volume at 1/2 MAX and adjust until the volume level is optimal. If the volume control is set too high, you may overload your mixer or amp.
   Note: As when making any connection, make sure the amplifier or mixing board volume is at the minimum level before plugging in the receiver to avoid possible sound system damage.

6. LED Display The DW-11/DW-22 receivers are equipped with AF LED indicator (4) showing the audio present from the transmitter. If this LED lights continuously, decrease the volume to the Mic or overload distortion may result. The RF LED DISPLAY (3) showing the TRANSMITTERS(TX) is on. When it is lit up, the TX is in usable range. If not lit up or flickering, either the TX is not on or it is out of range. Move the TX closer to re-establish the connection.

HANDHELD OPERATION

1. Unscrew the BATTERY COMPARTMENT COVER (14) and insert 2 fresh AA ALKALINE BATTERIES into the BATTERY COMPARTMENT(15), observing the correct polarity as marked. Screw the cover back on to the microphone. Fresh alkaline batteries can last up to 11 hours in use, but in order to ensure optimum performance, it is recommended that you replace the batteries after every 8-10 hours of use.
2. Turn on the DIGITAL HT™ by sliding the POWER SWITCH (13) to turn on the TX first. The RF LED (3) on the DW-11/DW-22 receivers should now be lit, indicating a received signal from the transmitter. The BATTERY INDICATOR LED (12) will give a single quick flash, indicating usable battery strength. In the case of a dead or low battery, it will either not go on at all or will stay on continuously, indicating that the batteries should be replaced with fresh ones. To preserve battery life, turn the transmitter off when not in use.
3. The microphone is now ready to use. Adjust the volume of the receiver per the Audio Output Microphone Connection section above.

Note: Observe care in selecting P.A. volume, transmitter location and speaker place-ment so that acoustic feedback (howling or screeching) is avoided.

BODYPACK OPERATION

1. Open the hinged BATTERY DOOR (22) and insert 2 fresh AA ALKALINE BATTERIES into the BATTERY COMPARTMENT (21), observing the correct polarity. Fresh alkaline batteries can last up to 11 hours in use, but in order to ensure optimum performance, it is recommended that the batteries be replaced after 8-10 hours of use.
2. Turn on the DIGITAL LT™ by sliding the POWER SWITCH (17) to audio MUTE position first. The RX RF LED INDICATOR (19) will turn on. The BATTERY INDICATOR LED (19) will give a single quick flash, indicating usable battery strength. In the case of a dead or low battery, it will either not go on at all or will stay on continuously, indicating that the batteries should be replaced with fresh ones. To preserve battery life, turn the transmitter off when not in use.
3. The microphone is now ready to use. When ready to speak, slide the audio POWER SWITCH (17) to the ON position. The RF LED (19) on the DW-11/DW-22 receivers should now be lit, indicating a received signal from the transmitter. Adjust the volume of the receiver per the Audio Output Microphone Connection section above.

Note: Observe care in selecting P.A. volume, transmitter location and speaker placement so that acoustic feedback (howling or screeching) is avoided.

1. The DIGITAL LT™ is provided with a 3.5 mm LOCKING JACK (18) for connecting the audio input selected. Connect either HEADWORN MIC or LAVALIER MIC CORD (23) as desired, according to the model selected.
   Note: Use only the input selected or the audio will not be optimal–a muddy or distorted sound may result. To secure the connection, turn the slip ring on the plug clockwise to thread it on the jack. To unplug, reverse the process.
   Slip the transmitter into a pocket or BELT CLIP (20) on to your clothes.

2. Microphone Use (with either a Lavalier or Headworn microphone)
   Secure the connection from the LAVALIER or HEADWORN MIC CORD(23) by turning the slip ring on the plug into the transmitter clockwise to thread it onto the jack. To unplug, reverse the process. To use the Lavalier Mic, attach it at chest level. Do not place it too close to the mouth–a distance of about six inches usually works best. To use the head worn Mic, place it on the head and adjust the boom so that the Mic is about one inch to the side of the front of the mouth.
   Note: Observe care in selecting P.A. volume, transmitter location and speaker placement so that acoustic feedback (howling and screeching) is avoided. Also note the pickup pattern characteristics of the microphone selected: Omnidirectional mics pick up sound equally from all directions and are prone to feedback if not used carefully. Unidirectional Mics are more resistant to feedback, but pick up sound sources best that are directly in front of the Mic. Mics that are farther from the sound source, such as lavaliers, require more acoustic gain and thus are also more prone to feedback than close-source Mics such as handheld or headworn models that are used close to the mouth.

3. Sample Connections: Connect ¼” output for A and B Channels to Mixer inputs. Use the volume to set for optimum output. VOLUME CONTROL (6) is for LINE/MIX 1/4” jack (8) AUDIO OUTPUT only. For separate control, use XLR outputs to each Mixer input, control the level from the Mixer. Power adapter connection as shown in the picture below.

PRECAUTIONS AND TROUBLESHOOTING

• Audio Feedback
  Avoid acoustic feedback (howling or screeching) by taking care in selecting P.A. volume, transmitter location and speaker placement.
  Note: the pickup pattern characteristics of the microphone selected: Unidirectional microphones are more resistant to feedback. However, they pick up sound sources best that are directly in front of the microphone. Mics that are farther from the sound source (such as a lavalier) require more acoustic gain and thus are also more prone to feedback than close-source Mics.]

• No Or Low Audio
  If you are not getting audio through the system, carefully re-check all setups. Especially note that the receiver and transmitter must be set to operate on the same RF channel. Also confirm that the BODYPACK transmitter’s POWER SWITCH (17) is not in the MUTE/STBY position. The receiver’s UNBALANCED MIX OUT (8) is adjustable so make sure the VOLUME CONTROL (6) is set properly.

• RF Interference and Finding Open Channels
  The FCC mandates that the following information be provided to all users of this equipment:

CONSUMER ALERT

Most users do not need a license to operate this wireless microphone system. Nevertheless, operating this microphone system without a license is subject to certain restrictions: the system may not cause harmful interference; it must operate at a low power level (not in excess of 50mW); and it has no protection from interference received from any other device. Purchasers should also be aware that the FCC is currently evaluating use of wireless microphone systems, and these rules are subject to change.
For more information, call the FCC at 1-888-CALL-FCC (TTY: 1-888-TELL-FCC) or visit : www.fcc.gov/cgb/consumerfacts/wirelessmic_factsheet.html

Please note that wireless frequencies are shared with other radio services. According to FCC regulations, wireless microphone operations are unprotected from interference from other licensed operations in the band. If any interference is received by any Government or non-government operation, the wireless microphone must cease operation or change frequencies. The above statement is valid only for use in the U.S.A.

If you encounter slight receiving interference when the transmitter is far from the receiver (from other than an operating TV station on the same frequency), it can often be overcome by relocating the receiver to a different place, away from RF sources, e.g., TV, radio, computer, electric motors.

MISCELLANEOUS USEFUL TIPS

• The receiver antennas should be kept away from any metal surfaces whenever possible as they can reflect away or shield the incoming RF signal.
• If the receiver’s volume control is set too high, it may overdrive the input of the attached audio mixer, causing distortion. Conversely, if the output is set too low, the overall signal-to-noise ratio of the system may be reduced, causing noticeable hiss. If such noise occurs, adjust the output level of the receiver so that highest sound pressure level going into the microphone transmitter causes no input overload in the mixer, but permits the mixer level control to operate in the normal range (not too high and not too low). This provides the optimal signal-to-noise for the entire system.
• Before inserting the batteries, ensure that they are being inserted with the correct polarity.
• Before operation, confirm that the receiver and associated transmitter are tuned to the same frequency group and channel number.
• Use only new AA alkaline or fully recharged NiMH batteries. Do not use “general purpose” carbon batteries. When batteries are weak, replace all the batteries at the same time. Do not mix new and old batteries.
• Position the receiver so that it has the least possible obstructions between it and the transmitter. Line-of-sight is best!
• During operation, the transmitter and the receiver should be as close as possible to each other for optimum results but never closer than 3 ft. (1 m) as that may overload the receiver’s input circuitry and cause feedback and interference.
• If rackmounting the receiver, keep away from heat sources such as amplifiers by allowing enough space between them for adequate ventilation. Also, position the receiver in the rack so the antennas can be optimally adjusted as described above.
• For the best operation, the receiver should be placed at least 3 ft. (1 m) above the ground and 3 ft. (1 m) away from a wall or metal surface. The transmitter should also be at least 3 ft. (1 m) from the receiver. Keep antennas away from noise sources such as motors, automobiles, neon lights, signal processors, computers and large metal objects.
• A receiver cannot receive signals from two or more transmitters simultaneously.
• Turn the transmitter off when it is not in use. For longest life, remove the batteries if the unit is not to be used for a long period as the transmitters draw a tiny residual current to maintain the programmed settings even when turned off. Also, since batteries installed for a long time can sometimes corrode and/or leak, causing damage, it is generally recommended that batteries be removed whenever the transmitters are not being used.
