Rack Mounting the Receiver

There are 2 options available (as accessories) for rack mounting the UDR800 receiver: single or side-by-side with another UDR800 receiver.

1. Single Mounting (RPK89): Remove the receiver SIDE MOUNT CLIPS from each side of the receiver (as shown) and slide in the optional wider RACK EARS.
2. Side-by-Side Double Mounting (RPK90): After removing the SIDE MOUNT CLIPS from both UDR800 receivers, join the two receivers with the JOINING CLIP and attach the narrow RACK EARS as shown.

(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 UDR800. Always ensure adequate airflow and heat dissipation in any rack configuration.)

Powering the Receiver

Plug the 22V DC ADAPTER provided into the DC INPUT JACK on the back of the receiver. Then plug the power supply into an AC outlet. Press the POWER SWITCH once to turn on the receiver. The POWER "ON" LED will now light and the receiver is operational.

Antennas

The UDR800 receiver is equipped with attached dual FOLDING ANTENNAS. Optimal positions of the antennas are 45° from the receiver (or 90° 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.

Adjusting the Mute Level/RF Squelch

The MUTE LEVEL/RF SQUELCH can be changed anytime during the main screen display to quiet the receiver in high noise environment conditions. The control ranges are from level 0 to level 5. The level should be adjusted to a lower number to the minimum RF squelch setting at which the RF INDICATOR will remain on while your transmitter is in normal use, up to the maximum operating range anticipated in use for your application. However, in areas of high RF activity, the squelch control may need to be adjusted to a higher number. If the transmitter is off and the receiver signal RF INDICATOR or the diversity A or B INDICATOR flickers or stays on continuously, the squelch should be adjusted to a higher number to stop the flickering. Be careful not to select too high a number setting as this may reduce the operating range to below what is needed. A range walk test will help in selecting the proper level. If the range is not critical, note that a higher level (maximum squelch) setting will also yield a quieter mute function, which might be desired in certain applications. The squelch level is factory preset at maximum sensitivity and operating range (i.e. level 0 for minimum squelch level — maximum usable range).

(Note: For easier intuitive operation, the MIN and MAX indicators for this control refer to the minimum and maximum operating range settings, not to the actual mute levels selected, which are the opposite as per above.)

Audio Level and Peak LED Indicator

The UDR800 receiver has a 5-bar AF LCD display that indicates normal level audio signal from the transmitter. Occasional flickering of the fifth AF LCD (peak level) on loud inputs to the transmitter is normal. If the AF LCD lights up full bars continuously, decrease the input audio level to the transmitter or overload distortion may result.

Connecting the Audio Output

The UDR800 receiver provides both a fixed MIC level BALANCED MIC OUTPUT XLR and an adjustable unbalanced line level AUDIO OUTPUT 1/4"Jack.

(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.)

HANDHELD MIC TRANSMITTER

Microphone Battery Installation

Install batteries by unscrewing the BATTERY COMPARTMENT COVER counterclockwise and remove, exposing the BATTERY HOLDER. Insert two fresh AA ALKALINE BATTERIES, observing the correct polarity, and screw the cover back on to the microphone. Make sure the cover is screwed clockwise completely. Fresh alkaline batteries can last up to 10 hours in use, but in order to ensure optimum performance, it is recommended that you replace the batteries after every 7-8 hours of use.

Programming to Selected Group/Channel (Frequency)

The transmitter must be programmed to the same frequency as selected for the receiver via automatic synchronization using the IR ASC™ Sync function. It can not be programmed on the transmitter itself. See "Selecting the Receiver Group/Channel and Programming" in next section. To manually IR program the receiver preselected frequency into the transmitter, place the transmitter's IR RECEPTOR SENSOR WINDOW 6-12" away from the receiver's IR WINDOW. Press the MENU BUTTON four times to the IR Screen then press the UP BUTTON to start IR programming. This flashing IR INDICATOR icon indicates IR transmission is in progress. When the synchronization is completed successfully, the RF INDICATOR and the diversity A or B INDICATOR on the receiver will show up.
(See section on Selecting the Group/Channel (Frequency) and IR Programming for transmitters.)

(Note: If no button is pressed for a five second period during a selection, the program is terminated and the process needs to be repeated.)

Operating the Handheld MIC Transmitter

Turn on the UHT800 by sliding the AUDIO MUTE to the OFF position first. Then slide the POWER SWITCH to the ON position. The TX LED INDICATOR (green) will stay on to indicate that the transmitter is on. The LOW BATTERY INDICATOR LED (red) will stay OFF, indicating usable-battery strength. In the case of a dead battery, the BATTERY INDICATOR LED will stay on continuously, indicating that the batteries should be replaced. To preserve battery life, turn the transmitter off when not in use.

The microphone is now ready to use. The A or B DIVERSITY LED INDICATOR on the UDR800 receiver should now be lit, indicating a received signal from the transmitter. When ready to speak, slide the AUDIO MUTE to the ON position.

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

(Note: The windscreen of the UHT800 functions as a built-in antenna. For proper operation, never remove the windscreen during use, or exchange with another type. For optimum range, maintain line-of-sight between the transmitter and the receiver whenever possible. Holding the microphone tightly, bridging across the windscreen and mic tube, will also lessen range. Hold MIC by the MIC tube housing only for optimum operation.)

For optimum performance, an AUDIO INPUT LEVEL is provided. Adjust the gain by turning the control with a small screwdriver. It is recommended that the level be set at about 1/2 maximum. Experiment and set for maximum possible gain without audible distortion on the high level peaks.

(Note: Turning down the gain too much can compromise the signal-to-noise ratio, and is not recommended.)

BODY-PACK MIC TRANSMITTER

Body-Pack Battery Installation

Open the BATTERY DOOR by pulling on side tabs and swinging the lid open. Insert two fresh AAA Alkaline Batteries into the BATTERY COMPARTMENT, observing the correct polarity. Fresh alkaline batteries can last up to 8 hours in use, but in order to ensure optimum performance, it is recommended that the batteries be replaced after 5-6 hours of use.

Lavaliere MIC Connection/Operation

The UBP800 is provided with a 3.5 mm INPUT JACK for connecting the audio input. Connect the LAVALIERE MIC CORD here. To secure the connection, turn the slip ring on the plug clockwise to thread it on the jack. To unplug, reverse the process. To use the Lavaliere MIC, attach it at chest level. Do not place it too close to the mouth. A distance of about six inches usually works best. When ready to speak, slide the AUDIO MUTE SWITCH to the ON position. Slip the transmitter into a pocket or use the CLIP on the rear of the unit to attach to your clothes

Programming to Selected Group/Channel (Frequency)

The transmitter must be programmed to the same frequency as selected for the receiver via automatic synchronization using the IR ASC™ Sync function. It can not be programmed on the transmitter itself. See "Selecting the Receiver Group/Channel and Programming" in next section.

To manually IR program the receiver preselected frequency into the transmitter, place the transmitter's IR RECEPTOR SENSOR WINDOW 6-12" away from the receiver's IR WINDOW . Press the MENU BUTTON four times to the IR Screen then press the UP BUTTON to start IR programming. This flashing IR INDICATOR icon indicates IR transmission is in progress. When the synchronization is completed successfully, the RF INDICATOR and the diversity A or B INDICATOR on the receiver will show up.
(See section on Selecting the Group/Channel (Frequency) and IR Programming for transmitters)

(Note: If no buttonis pressed for a five second period during a selection, the program is terminated and the process needs to be repeated.)

Operating the Body-Pack MIC Transmitter

Turn on the UBP800 by sliding the AUDIO MUTE SWITCH to the OFF position first, then slide the POWER SWITCH to the ON position. The bi-color LOW BATTERY INDICATOR will stay ON (green) indicating usable battery strength and that the transmitter is ON. In the case of dead or low batteries, the LED will either not go on at all or will stay ON (red) continuously, indicating that the batteries should be replaced with fresh ones. To preserve battery life, turn the transmitter OFF when not in use. The A or B DIVERSITY LED INDICATORS on the UDR800 receiver should now be lit, indicating that signal is being received from the transmitter.

(Note: The UBP800 is supplied with a removable ANTENNA. It should always be operated with the supplied antenna. For optimum operating range, always maintain line-of-sight between the transmitter and the receiver whenever possible.)

Microphone Use

Secure the connection from the LAVALIERE MIC to the INPUT JACK on the Body-Pack. To use the LAVALIERE MIC, attach it to the body at chest level. Do not place the MIC too close to the mouth. A distance of about six inches usually works best. When ready to speak, slide the AUDIO MUTE SWITCH to the ON position.

(Note: Observe care in selecting P.A. volume, transmitter location, and speaker placement so that acoustic feedback (howling and screeching) will be avoided. Please also note the pickup pattern characteristics of the microphone selected. Omni-directional mics pickup sound equally from all directions, and are prone to feedback if not used carefully. Uni-directional mics are more resistant to feedback, but best pick up sound sources that are directly in front of the mic. Also, mics that are farther from the sound source, such as lavalieres, require more acoustic gain and thus are more prone to feedback than close-source mics such as handheld models that are used close to the mouth.)

For optimum performance, an INPUT VOLUME LEVEL is provided. Adjust the gain by turning the control with a small screwdriver. For lavaliere mic use, it is recommended that the level be set at about 2/3 maximum. Experiment and set for maximum possible gain without audible distortion on the high level peaks.

SELECTING THE GROUP/CHANNEL AND SIMULTANEOUS MULTICHANNEL OPERATION

(Note: The transmitter should be turned ON and ready for the IR communications with the receiver IR receptor for the following process.)

(Note: If no button is pressed for a five second period during a selection, the program is terminated and the process needs to be repeated.)

(Note: For normal operation, the transmitter should have the same channel as displayed on the receiver.)

Choosing Group/Channel for the System

The receiver offers a choice of 15 groups: 10 that are Factory PRESET (Group 11 to 1A) and 5 that are User SELECTABLE (Group 1B to 1F). If the Factory PRESET Group mode is chosen, only a limited numbers of channels are available in these groups. For most convenient setup, each of these groups offers from 3 to 14 channels (depending on group selected) to choose from that are factory preset for simultaneous multichannel operation compatibility and are retained in memory after the receiver is powered off. For the User SELECTABLE Group 1B-1F mode, a letter "U" will light up on the LCD DISPLAY instead of the CHANNEL number as in the Factory PRESET Groups. Each User SELECTABLE Group has 800 channels to choose from either by manually selecting a channel or using the Auto-Scan in 1MHz segment increments at a time within the frequency band and they are retained in memory after the receiver is powered off. This facilitates easy setup by enabling quick selection of stored channels for any group, i.e, selecting any group will automatically display the last channel selected for that group. See Frequency Listings section for available channels in each group. The previous group and channel used is stored in memory automatically when receiver and transmitter are turned off after operation. Selecting a different group on the receiver in subsequent use will display a different channel as previously selected for that group, however, the transmitter will need again to be sync'ed to that new frequency to complete the system setup for operation.

Receiver ASC/IR Sync GR/CH (Frequency)

If different frequencies than previously stored in both the receiver and transmitter memories are needed, there are three ways to program the receiver and then sync the selected Group/Channel to the transmitter: One-Touch Automatic ASC™/Auto Sync receiver to transmitter, manual SCAN for Group/Channel, or manual select Group/Channel from the Factory preset or User Selectable channel. Place the transmitter's IR RECEPTOR SENSOR WINDOW 6-12" away from the receiver's IR WINDOW before starting the following steps.

• For One-Touch channel Autoscan and Automatic ASC™/Auto Sync from the receiver to thetransmitter, press the MENU BUTTON once, wait for about 5 seconds, the receiver will start the process automatically with no further user action required. A running bar in a clockwise direction on the LCD DISPLAY shows the scanning process which normally takes about two seconds. When it finds an interference-free channel, the receiver stores the channel for use, and it will begin ASC™ sync IR download of the selected channel to the transmitter automatically.
• To manually scan the selected Group/Channel, press the MENU BUTTON twice for the AUTOSCAN menu, press the UP BUTTON once and it will start scanning. A running bar in a clockwise direction shows the scanning process, which normally takes about 2 seconds. When it finds an interference-free channel, it will display and store the frequency/channel for use. It can be rescanned again for a new frequency by pressing the UP BUTTON or by pressing the MENU BUTTON twice to IR MENU (IR icon will light up for IR function), then press the UP BUTTON to start IR programming.
• To manually select Group/Channel, press the MENU BUTTON once for GROUP selection for Factory PRESET Group 11 to 1A mode or User SELECTABLE Group 1B to 1F mode. Use the UP/DOWN buttons to change the group. After selecting a group, press the MENU BUTTON twice for channel selection menu. Use the UP/DOWN buttons to change the channels (frequencies) that are available in each group.
  (Note: for Group11 to 1A, the CH display will indicate the channel number chosen, and for Group 1B to 1F only the letter "U" and the frequency chosen will be displayed. See Frequency Listings section for available channels in each group.)
  After finishing channel selection, press the MENU BUTTON once or wait a few seconds for IR MENU, and then press the UP BUTTON to start IR programming.

This completes the GP/CH (frequency) programming. The next section outlines the procedure for sync'ing the receiver's programmed channel to the transmitter.

Receiver ASC/IR Sync Manual Programming

To manually program the pre-selected Group/Channel (frequency) from the receiver to the transmitter, place the transmitter's IR RECEPTOR SENSOR WINDOW 6-12" away from the receiver's IR WINDOW. Press the MENU BUTTON four times to the IR Screen Display and then press the UP BUTTON to start IR programming. The flashing IR INDICATOR icon indicates IR transmission is in progress. When the synchronization is completed successfully (usually in less than 2 seconds), the RF INDICATOR and the diversity A or B INDICATOR on the receiver will display, indicating that the IR linking is completed. The LCD DISPLAY SCREEN will show the selected channel. If the UP Button is not pressed during the two seconds of active data transfer, the IR INDICATOR will not flash, the LCD Display will revert to the main menu, the receiver will not link to the transmitter, and the transmitter's previously programmed channel remains unchanged.

Instructions for the Setup of Simultaneous Multichannel Operation

This UDR800 receiver is capable of finding an open channel with its autoscan capability. This built-in feature is a quick, convenient way to set up many wireless systems at the same location for simultaneous multichannel operation.

If you are using multiple transmitters at the same location, set up the first transmitter and leave it ON and keep it 10 feet away from the receivers and 1 foot or more between transmitters. This avoids possible duplicate selection of the same channel as already selected for the first receiver. Then start the autoscan function on the second receiver. Repeat this procedure for all receiver/transmitters to be used in your system. Finally with all the transmitters ON, perform a range walk test in the location these systems will be used in to check for potential crosstalk interference in this application.

If you are not satisfied with any of the channels scanned, repeat the autoscan procedure for that receiver again anytime for finding another free channel. This process can be simplified if you select channels within Factory SELECTED Groups 11 to1A, as the channels within those groups are mutually compatible (unless there is outside interference on any of the selected frequencies). If there is any such interference in your location, select as many channels as you can using these 10 groups and then select additional open channels as needed (depending on number of systems to be operated simultaneously) from Groups 1B to 1F. As noted above, all these groups will retain in memory the previously selected channels for that group for easy setup subsequently in that same location

FRONT PANEL LOCK-OUT

Locking Front Panel Controls

In order to avoid accidental re-programming or scanning, there is a Front Panel Lock-Out feature. By pushing the MENU BUTTON and the UP BUTTON simultaneously, the UDR800 will enter a lock-out state. A LOCK-OUT SYMBOL will be displayed on the front panel. The lock-out feature will inhibit the functions of the MENU, UP, and DOWN controls. To unlock, press the MENU BUTTON and the UP BUTTON simultaneously again.

RF INTERFERENCE & FINDING OPEN CHANNELS

• The FCC mandates the following information be provided to all end 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
• 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 adjusting the receiver's MUTE LEVEL/SQUELCH. If receiving interference on a selected channel with the transmitter off, you must reprogram the receiver and transmitter to a different channel.
• To reprogram, you must first find an open channel. To do this, follow the procedure outlined in Selecting the UDR800 Receiver Channel. With the associated transmitter off, scroll through the channels to find one that shows no received signal (not lit) on the receiver's RF INDICATOR and A or B INDICATORS. Also, neither of these LCDs should be lit on each of the three immediately adjacent channels both above and below the selected channel for optimal interference-free operation (i.e., in a field of seven total adjacent channels—with the channel used in the middle). If operating multiple UDMS800 Series systems simultaneously, repeat this procedure with every new channel being selected, with previously tuned systems all on, both transmitters and receivers. Also see: Programming the Selected Group/Channel (frequency) & IR Programming (Receiver & Transmitter) in the previous section.
• 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 nongovernment operation, the wireless microphone must cease operation or change frequencies.
  The above statement is valid only for use in the U.S.A.
