System Operation

UWS-100 Receiver

Powering the Receiver

To power the receiver, plug the provided

DC POWER SUPPLY UNIT (14) adapter into the

DC INPUT JACK (8) on the back of the receiver, then plug the adapter into a 120VAC outlet.

Note: Any 15-18VDC source with minimum 400mA capacity can also be used.

The Power Rocker Switch (9) is used to turn the receiver on or off. To turn on, press down the right side of the switch

(“I”). The LED Display (3) will light, showing Channel 00 99. The AF LED (4) and RF A/B LEDs (5) remain dark. They will display the received RF A/B and audio level when

the transmitter is activated and audio transmitted. To turn off, press down the left side of the switch (“O”). The receiver will turn off. All the LEDs will be turned off, indicating the receiver is off. At power off the UWS-100 receiver will store the last selected channel and re-display them at power on. It can be reprogrammed to any new channel. The default factory setting is Channel 14.

Rackmounting Receivers

A single or dual UWS-100 receivers can be rackmounted with the optional RMT-1KUD rack tray.

Adjusting the Squelch

The MUTE LEVEL/RF SQUELCH (13) controls the mute circuits in the receiver. The control should be adjusted clockwise to the minimum RF squelch setting at which the RF A/B LED (5) 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 counterclockwise. If the transmitter is off and the receiver signal diversity A or B LED indicator flickers or stays on continuously, the squelch should be adjusted counterclockwise to a higher level to stop the flickering. Be careful

not to select too high a counterclockwise 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 counterclockwise (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. clockwise for minimum squelch level—maximum usable range).

Note: For easier intuitive operation, the MIN and MAX indications 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.

Adjusting Antennas

The UWS-100 has two permanently attached, flexible elbow antennas (1) for diversity reception. Unfold and rotate these antennas to operate the receiver. The optimal positions of the antennas are flared 45° out from the receiver sides and

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.

Selecting the UWS-100 Receiver Channel

See RF Interference and Finding Open Channels in the Cautions and Troubleshooting section. This section will also aid in finding desired channel(s) of operation when setting up your system(s).

The Select Button (2) has two functions. A short press (~1 second) scans for a clear channel and a long press (> 2 seconds) manually programs a desired channel.

Press the Select button for one second to start the 100 channel (00-99) Autoscan for open frequencies. A running bar in a clockwise direction shows the scanning

process which normally takes ten seconds. When it finds an interference-free channel, it will stop and store the channel for use.

If manual channel selection is preferred, press and hold the Select button for at least two seconds to start programming to a desired channel. The right digit will flash for five seconds. Select the desired digit by briefly pressing the Select button to scroll though choices 0-9 until the desired number is displayed. Then, to switch between the right and left digits, press and hold the Select button for two seconds. As with the right digit, briefly pressing the Select button again will advance the left digit displayed to the next higher number 0 to 9. This completes the manual channel programming.

Note: If the Select button is not pressed within the five seconds flashing period during either the right or left digit selection, the program is terminated and the process needs to be repeated.

The ASC Sync Button (7) is used to transfer the selected channel info from the receiver to the transmitter for easy synchronization prior to use. Briefly press the ASC Sync button to start the transfer. A red LED inside the IR LED (6) window will flash twice quickly within two seconds. This LED indicates

IR transmission is in progress. If needed, press the ASC Sync button again, to restart synchronization. When the synchronization is completed successfully, either the diversity RF A or B LED (5) on the receiver will light up.

To program the preselected channel into the transmitter, place the transmitter’s

IR Receptor Sensor Window (17, 29)

6-12” away from the receiver’s IR Window

(6). Press the ASC Sync Button (7) once to start programming. (See Programming the UHT/UBT-100 Transmitters to the Selected Channel in the following section.)

Instructions for Setup of Simultaneous Multichannel Operation

The UWS-100 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 10 feet away from the receivers and 1 foot away from transmitter to transmitter. This avoids possible duplicate selection of the same channel as already selected for the first receiver. Then start the Autoscan function on the second UWS-100 receiver. Repeat this procedure for all receivers/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.

Audio Level and Peak LED Indicator

The UWS-100 receiver has a bi-color AF LED (4) that lights up green indicating normal level audio signal from the transmitter. Occasional flickering of the

AF LED as orange (peak level) on loud inputs to the transmitter is normal. If the LED lights orange continuously, decrease the input audio level to the transmitter or overload distortion may result.

Connecting the Audio Output

The UWS-100 audio output is set up for either adjustable level ¼” Unbalanced Line Out (11) or fixed level XLR Balanced Mic Out (10). The ¼” unbalanced line out

8

9

is controlled by the Volume Control (12).

For unbalanced line output connection, plug an audio cable with a ¼” mono (Tip/Sleeve) plug into the Unbalanced Line Out jack and plug the other end into your mixing board or amplifier. Adjusting the Volume control will increase or decrease the audio level at the ¼” Unbalanced Line Out only. When using the UBT-100 instrument transmitter system, connect the Unbalanced Line Out directly to your instrument amp or preamp. At maximum receiver volume setting, the system output is approximately +4dB higher than a direct cord-to-amp connection.

For XLR Balanced Mic Output connection, plug an audio cable with an XLR connector into the XLR Balanced Mic Out (10) socket and plug the other end into your mixing board or amplifier and control the audio levels from there.

Both the ¼” Unbalanced Line Out and the XLR Balanced Mic Out can be used at the same time to connect to your mixing board, effect, or amplifier.

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.

Note: Only one transmitter can be used with one receiver. It is not possible to use two transmitters on the same frequency and mix the output of these transmitters into one wireless receiver.

Your UWS-100 receiver is now operational and ready to use. Proceed to the following instructions for the UHT-100 handheld microphone transmitter or UBT 100 bodypack transmitter included with

your system.

UHT-100 Handheld

Microphone Transmitter

Setting up the Transmitter

The UHT-100 requires two AA alkaline or NiMH batteries to operate (do not mix types). To install the batteries, press at the “Open” end of the Battery Cover (23) and slide down per the arrow indicator, exposing the Battery Compartment (19). Insert two fresh AA batteries according to the polarity indicated on the transmitter body. Slide the battery cover back onto the microphone, making sure it is secure. Fresh alkaline batteries can provide up to 8-10 hours of operation, but in order to ensure optimal performance it is recommended that the batteries be replaced after 6-8 hours of use or as indicated necessary by the flashing BATT icon (16B). The transmitter has a built-in

Internal Antenna (22). For best operating range, do not handle this antenna during use.

The UHT-100 handheld transmitter has two small switches under the battery cover; the TRANSMITTER LOCK SWITCH (20) and the

RF HI/LO POWER SWITCH (21). To access these two switches, slide down and remove the cover. These switches have ON and OFF positions and function as follows:

When the transmitter lock switch is in the OFF position, the key icon (16C) does not appear on the LCD DISPLAY (16). To prevent the possibility of accidentally turning off the transmitter during use, switch it to the

ON position. The key icon will appear on the LCD display and the transmitter OFF/STBY/ ON switch will be disabled. The standby and IR channel programming will still function normally.

The RF HI/LO power switch can be set either in HI (more RF output) or in LO

(less RF output). The LO setting will prolong battery life and is also recommended for

simultaneous multichannel operation. Select the level for your application accordingly. A range walk test will determine if the LO setting is adequate.

Powering the Transmitter On/Off

To turn on the transmitter, slide the

Off/Stby/On Power SwiTCH (18) to the middle standby position. The LCD backlight (16) will light up, indicating the unit is now on. After five seconds the backlight will automatically turn off to conserve battery life. The LCD Display (16) indicator icons stay on for normal operation.

As many of the five LCD display battery level bars (16B) should stay lit as possible, indicating usable battery strength. As

the batteries weaken, fewer of the level indicators will stay lit until only one bar shows, which will then flash “BATT” to warn that the batteries are now too low and should be replaced as soon as possible with fresh ones.

To preserve battery life, turn the transmitter off when not in use. To turn the transmitter off, check that the Transmitter Lock Switch (20) is in OFF position with the Key Icon (16C) not showing on the LCD Display (16). Then slide the power On/Off switch to the OFF position. The LCD or backlight are not lit up, indicating the unit is off.

At power off the transmitter will store the last settings entered and re-display them at the next power on. The default factory setting is Channel 14.

Programming the UHT-100 to the Selected Channel

The transmitter must be programmed to the same frequency as selected for the receiver via automatic synchronization using the IR ASCSync function. It can not be programmed on the transmitter itself.

IR Sync Programming

Use the wireless IR Receptor Sensor Window (17) infrared LED to download pre programmed channels from the receiver.

Start programming by holding the IR receptor sensor/window about 6-12” from the front of the receiver, then press the ASC Sync Button (7) briefly on the receiver. The red LED inside the receiver’s IR Window (6) will flash twice quickly within two seconds. This LED indicates IR

transmission is in progress. If necessary, the ASC transfer can be repeated by pressing the ASC Sync button again. When the synchronization is completed successfully, either the RF A or B LED (5) on the receiver will light up. Upon successful data transfer (usually in less than two seconds) the transmitter’s backlight will light up and the transmitter will transmit a radio signal on the same channel as the receiver. The diversity RF A/B LED indicator on the receiver will then light up, indicating that the IR linking

is completed. The LCD Display (16) will show the matching channel as receiver.

If no action is taken during the two seconds of active IR data transfer, the receiver and the transmitter units do not link and the transmitter’s previous program channel remains unchanged.

For normal operation, the transmitter should have the same channel as displayed on the receiver. The transmitter is now ready for use.

Note: The IR link is infrared light and thus works best when this data transfer is accomplished in a light-shielded or darker environment. It may not be successful in a brightly lit area. If the transfer fails, repeat the procedure in a darker location

or somehow shield the link from outside light to successfully program the transmitter with the pre-programmed group and channel info from the receiver.

Operating the UHT-100

Handheld Transmitter

The Off/Stby/On POWER SWITCH (18) has three positions and functions both as a power On/Off and as an audio mute On/ Standby switch. During normal operation with the unit powered on standby, slide the Off/Stby/On power switch to the ON position. You will feel a slight click indicating the ON position is selected. The receiver’s

RF A/B LED (5) diversity indicators should now be on, indicating a received signal from the transmitter.

After the unit is powered on, slide the power switch to the ON position to unmute the audio or to STBY to mute the audio. Set the power switch accordingly and the microphone is now ready to use. The receiver’s diversity RF A or B LED indicator should now be on, indicating a received signal from the transmitter.

When ready to transmit audio, slide the power switch to ON to un-mute. To mute, slide the power switch to STBY again. Adjust the volume of the receiver per the previous section, Connecting the Audio Output.

Note: Avoid acoustic feedback (howling or screeching) by taking care in selecting PA volume, transmitter location and speaker placement.

UBT-100 Bodypack Transmitter (LT, HM or GT)

Setting up the Transmitter

The UBT-100 bodypack requires two alkaline or NiMH AA batteries to operate (do not mix types). To install the batteries into the battery compartment, press at the arrow end and slide down and remove the Latching Battery Compartment Door (30), exposing the Battery Compartment (31). Insert two fresh AA

batteries according to the correct polarity as indicated on the transmitter body. Slide the battery compartment door back onto the transmitter, making sure it is secure. Fresh alkaline batteries can provide up to 8-10 hours of operation, but in order to ensure optimal performance it is recommended that the batteries be replaced after

6-8 hours of use or as indicated to be necessary by the flashing “BATT” icon. The transmitter has a removable Antenna (24) but it should be attached (screwed

on tightly counterclockwise). For best transmitting power during use, make sure it is not blocked. A walk test before use will determine the operating range in your application.

Powering the Transmitter On/Off

To turn on the transmitter, slide the Off/ Stby/On Power Switch (32) to the standby position. The LCD backlight will light up, indicating the unit is now on. After five seconds the backlight will automatically turn off to conserve battery life. The

LCD Display (27) indicator icons stay on for normal operation.

As many of the five LCD display Battery Level Bars (27B) should stay lit as possible, indicating usable battery strength. As the batteries weaken, fewer of the level indicators will stay lit until only one bar shows, which will then flash “BATT” to warn that the batteries are now too low and should be replaced as soon as possible with fresh ones.

To preserve battery life, turn the transmitter off when not in use. To turn the transmitter off, slide the power On/Off switch to the off position. No LCD or backlight is lit up and the unit will be off.

At power off the transmitter will store the last settings entered and re-display them at the next power on. The default factory setting is Channel 14.

Programming the UBT-100 to the Selected Channel

The transmitter must be programmed to the same frequency as selected for the receiver via automatic synchronization using the IR Sync function. It cannot be programmed on the transmitter itself.

IR Sync Programming:

Use the wireless IR Receptor Sensor Window (29) infrared LED to download pre programmed channels from the receiver.

Start programming by holding the IR receptor sensor/window about 6-12” in front of the receiver, then press the ASC Sync Button

(7) briefly on the receiver. The red LED inside the receiver IR Window (6) will flash twice quickly within two seconds. This LED indicates IR transmission is in progress. If necessary, the ASC transfer can be repeated by pressing the ASC Sync button again. When the synchronization is completed successfully, either the RF A or B LED (5) on the receiver will light up. Upon successful data transfer (usually in less than two seconds) the transmitter’s backlight will light up and the transmitter will transmit a radio signal on the same channel as the receiver. The diversity RF A or B LED indicator on the receiver will then light up, indicating that the IR link is completed. The LCD Display (27) will show the matching channel as receiver. If no action is taken during the two seconds of active IR data transfer, the receiver and the transmitter units do not link and the transmitter’s previous program channel remains unchanged.

For normal operation, the transmitter should have the same channel as displayed on the receiver. The transmitter is now ready for use.

Note: The IR link is infrared light and thus works best when this data transfer is accomplished in a light-shielded or darker environment. It may not be successful in a brightly lit area. If the transfer fails, repeat the procedure in a darker location

or somehow shield the link from outside light to successfully program the transmitter with the pre-programmed group and channel info from the receiver.

Connecting Input Audio Source

Lapel/Head Mic Uses (UBT-100 LT/HM)

The mini 3.5mm locking Input Jack (26) is for connecting the audio input from a lavalier/lapel mic (LT), a Headmic(HM), or an instrument (GT) cable, depending on which transmitter version is being used. Secure the connection to the cable by tightening the cable mini plug’s outer ring counterclockwise.

Instrument Use (UBT-100 GT)

Secure the connection of the GT (instrument) cable by tightening the mini plug outer ring counterclockwise onto the 3.5mm locking Input Jack (26). When ready to play, slide the Off/Stby/ On Power Switch (25) to the ON position to un-mute the audio. Adjust the volume on the receiver for one-to-one unity gain with a hardwired cord or select up to an

added 4-5dB boost by adjusting the receiver volume to maximum for normal use with guitars and bass guitars.

Note: The audio level should be adjusted on the instrument as when using a hard-wired cord.

Operating the UBT-100

Bodypack Transmitter

The Off/Stby/On Power Switch (25) has three positions and functions both as a power On/Off and as an audio mute On/ Standby switch. During normal operation with the unit set to Standby, slide the switch to the ON position. The receiver’s RF A/B LED (5) diversity indicators should now be on, indicating a received signal from the transmitter.

12

After the unit is powered on, slide the power switch to the ON position to un-mute the audio or to STBY to mute the audio. Set the power switch accordingly and the transmitter is now ready to use. The receiver’s RF A/B LED indicator should now be on, indicating a received signal from the transmitter.

When ready to transmit audio, slide the power switch to ON to un-mute. To mute,

slide the power switch to STBY again. Adjust the volume of the receiver per the previous section, Connecting the Audio Output.

Note: Avoid acoustic feedback (howling or screeching) by taking care in selecting PA volume, transmitter location and speaker placement.

Cautions and Troubleshooting

Feedback

Avoid acoustic feedback (howling or screeching) by taking care in selecting PA volume, transmitter location and speaker placement.

Please also 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. Also, mics that are farther from the sound source (such as a handheld) 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 transmitter’s Power Off/Stby/On Switch (18, 25) is not in the STBY position. The receiver’s Unbalanced Line Out (11) is adjustable so make sure the Volume Control (12) is set properly.

RF Interference and 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 (16)—see Adjusting the 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 UWS-100 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 A/B LEDs (5). Also, neither of these LEDs 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 UWS-100 Series systems simultaneously, repeat this procedure with every new channel being selected, with previously tuned systems all on, both transmitters and receivers. See

“Instructions for Setup of Simultaneous Multichannel Operation “

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.

Miscellaneous 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 inserted with the correct polarity.

Before operation, confirm that the receiver and associated transmitter are tuned to the same frequency group and channel number.

After making a receiver channel change, ensure that the corresponding change is also made on the matching transmitter.

Use only new 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 for optimum results but never closer than 3 ft. (1 m) as that may overload the receiver’s input circuitry and cause noises.

If rackmounting the receiver, keep away from heat sources such as amps by allowing enough space between them for adequate ventilation.

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, as well as 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.

When using the bodypack for instrument use: Scratchy noises can sometimes occur when an electric guitar with dirty pots or connections is used with a wireless system. Therefore, the supplied capacitor provides first-order filtering of the RF signal from the cord into the guitar and eliminates virtually all scratchy noises. Should your equipment still produce scratchy noise, we suggest these steps to eliminate problems:

1) Make sure all guitar volume and tone pots are clean and all contacts are solid. This is very important.

2) Solder a 47pF capacitor across the pot to ground terminal of the guitar’s volume and tone pots to provide extra filtering
