System Operation

W-1KU Receiver

Buttons Function

The Power Button (12) is used to turn the receiver on or off. When the button is pressed, the lit blue backlight on the

LCD Display (2) indicates the receiver is on. Press the Power button again to turn off the receiver. The backlight on the LCD will turn off indicating the receiver is off. At power-off the W-1KU receiver will store the last settings entered and re-display

them at power-on. It can be reprogrammed to any new Group/Channel, or Volume level. The default factory setting is Group 08, Channel 00, and Volume 63.

When the Set Button (8) is repeatedly pressed the LCD main menu will cycle in this order:

MAIN MENU > VOLUME > GROUP > CHANNEL > repeat

The selected function will flash for 20 seconds before returning to the main menu.

The (Up) or(Down) Buttons (9) are

active while in the Set mode, or can be used to change Volume Level (6) at anytime.

The IR Sync Button (11) is used to transfer the frequency-selected info from the receiver to the transmitter being used for easy synchronization prior to use. Press the IR Sync Button while the main menu is displayed, and the IR LED (10) will flash quickly. This LED indicates IR transmission is in progress. Press the SET Button

again to stop the flashing or it will halt in 20 seconds automatically.

Selecting the W-1KU Receiver Volume Level / Group / Channel

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

Press the (Up) or(Down) Buttons once or the Set button once prior to pressing or for single stepping through the Volume Levels (6). Or hold continuously for

faster level selection. Select one of 63 levels from the Volume menu and advance to Exit Set Up Mode by pressing the Set Button (8). Choose the W-1KU operating frequency

by selecting one of ten Groups (4) and one of 100 Channels (5) that are determined to be desirable open channels. Press the Set button twice to skip the volume setting and enter the Group setup mode, then press the or buttons once for single stepping through the groups. Or hold continuously for faster group selection. Select one of ten groups available from the Group menu and then advance to Channel Setup Mode by pressing the Set button. Or, press the Set button twice to exit without changing the channel. Press the or buttons three times or press the Set button again after group setting to enter the Channel setup mode. Press the or buttons once for single stepping through the channels,

or hold continuously for faster channel selection. Select one of 100 channels available from the channel menu or press the Set button again to exit.

Rack-mounting the Receiver

There are two options available for rack mounting the W-1KU: single or side-by-side with another W-1KU receiver.

Single Unit Rack Mount Kit (20): Attach the optional RMK-1KUS Rack Kit ears to each side and tighten with supplied screws.

Dual Unit Rack Mount Kit (21): Attach the optional RMT-1KUD Dual Receiver Rack Tray to bottom of both receivers and tighten with supplied screws.

Note: Do not mount the receiver on a rack directly above an amplifier or other source of high heat. This could degrade the performance of the W-1KU. Always ensure adequate airflow and

heat dissipation in any rack configuration.

8

Installing Antennas

Install antennas by connecting the two Antennas (19) included with your system to the two RF Connectors (18) located on the back of your W-1KU receiver. The optimal positions of the antennas are 45 degrees from the receiver and 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.

Powering the Receiver

To power the receiver, plug the provided

AC/DC Power Supply (14) adapter into the

DC Input Jack (13) on the back of the receiver, then plug the adapter into an AC outlet.

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

Connect either the 1⁄4” Unbalanced Line Out (17) or XLR Balanced Mic Out (15) to your mixing board, effect, or amplifier (see Connecting the Audio Equipment). To turn on, press the Power Button (12) for two seconds. The LCD Display (2) will light (showing Group, Channel, RF Level

Meter, Diversity, and Output Volume). The 5-segment AF LED Tree (1) will display the received audio level when the transmitter is activated and audio transmitted. To turn off, press the Power button for three seconds and release. The receiver will turn off.

Adjusting the Squelch

The RF Squelch (16) simultaneously controls both of the A and B True Diversity receiver mute sections. The control should be adjusted counterclockwise to the minimum RF squelch setting at which the RF Level Meter (7) and the Diversity Indicator (3) 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 clockwise. If the transmitter is off and the

receiver signal and the diversity indicators are flickering or stay on continuously, the squelch should be adjusted to a higher level (clockwise for less mute sensitivity level) to stop the flickering. Be careful not to select too high a clockwise 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 clockwise (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. counterclockwise for minimum squelch level—maximum usable range).

Audio Level and Peak LED Indicator

The W-1KU receiver has a 5-segment

AF Level LED Display (1) that lights up sequentially, indicating the level of the audio signal from the transmitter. Occasional flickering of the top (red) Peak LED on loud inputs to the transmitter is normal. If the Peak LED lights continuously decrease

the input audio level to the transmitter or overload distortion may result.

Connecting the Audio Output

The W-1KU audio output is set up for either balanced mic (fixed level) or unbalanced line (adjustable level). The Unbalanced Line Out is controlled by the or volume control buttons. The receiver Volume Display (6) will indicate the level selected. For balanced output, plug an audio cable with an XLR connector into the XLR Balanced Mic Out (15) socket and plug the other end into your mixing board or amplifier. For unbalanced output, plug an audio cable with a 1⁄4” mono (Tip/Sleeve) plug into the Unbalanced Line Out (17) jack and plug the other end into your mixing board or amplifier. When using the BT-1KU instrument transmitter system, connect the Unbalanced Line Out directly to your instrument amp or preamp.

9

At maximum receiver volume setting, as indicated by the Volume display, the system output is approximately +4dB higher than

a direct cord-to-amp connection.

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.

Your W-1KU receiver is now operational and ready to use. Once you have completed the above steps, proceed to the following instructions for the HT-1KU Handheld or BT-1KU Instrument transmitter included with your system.

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.

HT 1KU Handheld

Microphone Transmitter

Setting up the Transmitter

The HT-1KU requires two AA size batteries to operate. To install the batteries onto the battery compartment, unscrew the

Battery Compartment Cover (22) by turning counterclockwise until loose and slide down the cover, exposing the Battery Compartment (31). Insert two fresh AA batteries according to the correct polarity as indicated on the transmitter body. Screw the battery cover back onto the microphone, making sure

it is securely tightened. Fresh alkaline batteries can provide up to 8-10 hours of operation, but in order to ensure optimum performance it is recommended that the batteries be replaced after 6-8 hours of use or as indicated to be necessary by the flashing Battery (40) icon.

Powering the Transmitter On/Off

To turn on the transmitter, slide the power On/Off Switch (28) to the on position. The LCD backlight will light up, indicating the unit is now on. After ten seconds the backlight will automatically turn off to conserve battery life. The Group/Channel/Battery (24) indicator icons stay on for normal operation.

As many of the LCD battery levels should stay lit as possible, as they indicate usable battery strength. As the batteries weaken fewer of the level indicators will stay lit until only one bar shows, which will then flash 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.

Programming the HT-1KU to the Selected Channel

The transmitter can be programmed to the same frequency as selected for the receiver, either via automatic synchronization using the IR Sync function or manually on the transmitter itself.

IR Sync Programming:

Use the wireless IR LED Receptor Sensor (30) to download pre programmed channels from the receiver (see Selecting the W-1KU Receiver Volume Level/Group/Channel and Selecting the HT-1KU Transmitter Group and Channel). Start programming by holding the IR LED Receptor Sensor about 6”-12” from the receiver, then press the IR Sync Button (11) on the receiver. The red IR LED (10) on the receiver will flash once after one second indicating IR data transfer, and then once more at three seconds, indicating that the IR transmission is over. Upon successful data transfer (usually in less than two seconds) the transmitter’s backlight will light up and the transmitter will transmit

10

a radio signal on the same channel as the receiver. The Signal Strength and Diversity Indicators on the receiver’s LCD display will then light up, indicating that the IR link is completed. If no action is taken during the three seconds of active data transfer, the receiver and the transmitter units do not link and transmitter’s previous program channel remains unchanged.

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.

Manual Programming (GRP/CH and Volume):

The transmitter’s frequency is set using the

Set Button (26) and then the(UP) or(DOWN) Buttons (25). To start, press the Set button once. The backlight on the LCD (36) will light up and the Group Icon (24) will flash. Use the

or buttons to change the group. When a group selection is finished, press the Set button again for the channel selection. The Channel Icon (24) will now flash. Again, use the or buttons to change the channel as desired. When the Group/Channel selection is done, press the Set button to enter the volume level input setting and then press

or to change in four steps from 0dB to -30dB (for loudest input) or press the Set button a second time to exit to the main menu. To change the volume input level only, press the Set button three times to select the volume input level setting. Use

or to change in four steps from 0dB to -30dB (for loudest input). The level is preset at -10dB for the HT-1KU, which is best for most applications.

For normal operation, the transmitter should have the same Group/Channel as displayed on the receiver. After programming is finished, slide the battery cover back then turn the Mic Ball (23) counterclockwise to secure the housing. The HT-1KU is now ready for use.

HT-1KU Transmitter Switches

At Power Off the transmitter will store the last settings entered and re-display them at the next power on where it can be reprogrammed to any new Group/Channel. The default factory setting is Group 08, Channel 00.

The RF Power Level Switch (27) is used to select Hi/Low power transmission (see Operating the HT-1KU Handheld Transmitter).

Each time the Set Button (19) is pressed, the LCD main menu will cycle in this order:

MAIN MENU > GROUP > CHANNEL >

VOLUME > repeat

The selected function will flash for 20 seconds before returning to the main menu.

The orButtons (25) work in the set mode only. They can be used to change any Group/Channel as selected (if not using

IR Sync from receiver). They can also be used to select the desired Input audio level VOL setting.

Operating the HT-1KU

Handheld Transmitter

During normal operation with the unit powered on, the transmitter power level can be changed by sliding the RF Power Switch (27) to “H” to increase the transmitted RF power (for longer range) or to “L” to decrease the RF power (reduced range). This is a useful feature as the “L” setting increases battery life and also optimizes the number of channels that can be used simultaneously in a given location. Use this setting for normal use not requiring maximum operating range.

A range walk test before use will determine which setting is best for your application.

Slide the On/Off switch to the on position and the microphone is now ready to use. The receiver’s RF Signal Meter (7) and Diversity A or B (3) indicators should now

11

be on, indicating a received signal from the transmitter. Adjust the volume of the receiver per Connecting Audio Output.

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

Note: The RF Signal meter and the Diversity A/B indicator on the receiver’s LCD display should be “On” in normal operation.

BT-1KU Bodypack Transmitter (LT, LT/HM or GT)

Setting up the Transmitter

The BT-1KU bodypack requires two AA size batteries to operate. To install the batteries into the battery compartment, lift the

Battery Compartment Door (46) by grabbing the two spring-loaded locking tabs and pull out, exposing the Battery Compartment (45). Insert two fresh AA batteries according

to the correct polarity as indicated on the transmitter body. Close the battery cover, ensuring the cover is snapped shut. Fresh alkaline batteries can last provide up to 8-10 hours of operation, but in order to ensure optimum performance it is recommended that the batteries be replaced after 6-8 hours of use or as indicated necessary by the flashing Battery Meter (40).

Connecting Input Audio Source

Use Audio Input (33) 3.5mm locking mini jack for connecting the audio input cord from lapel mic (LT), Headmic(LT/HM), or instrument (GT), depending on which version transmitter is being used. Secure the connection to the cable by lining up the slot of the 3.5mm mini connector and turning the ring to securely lock in.

Powering the Transmitter On/Off

To turn on the transmitter, slide the

Power Off/Mute/On Switch (34) to the Mute (middle) position (transmitter on, audio muted). The LCD backlight will light up. The unit is now on. After ten seconds the backlight will automatically turn off. The Group Icon (37) and Battery Meter (40) remain on in normal operation.

As many of the five LCD battery levels should stay lit as possible, indicating usable battery strength. As the batteries weaken, fewer of the level indicators stay lit until only one bar shows, which will then flash to warn that the batteries are now too low and should be replaced as soon as possible. To preserve battery life, turn the transmitter off when not in use. To turn the transmitter off, slide the Off/Mute/On switch to Mute and then Off. No LCD or backlight is lit up and the unit will be off.

Programming the BT-1KU to the Selected Channel

The transmitter can be programmed to the same frequency as selected for the receiver, either via automatic synchronization using the IR Sync function or manually on the transmitter itself.

IR Sync Programming:

Use the wireless IR LED Receptor Sensor (41) to download pre programmed channels from the receiver (see Selecting the W-1KU Receiver Volume Level/Group/Channel and Selecting the BT-1KU Transmitter Group and Channel). Start programming by holding the IR LED Receptor Sensor about 6”-12” from the receiver, then press the IR Sync Button (11) on the receiver. The red IR LED (10) on the receiver will flash once after one second indicating IR data transfer, and then once

12

more at three seconds, indicating that the IR transmission is over. 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 Signal Strength and Diversity

Indicators on the receiver’s LCD display will then light up, indicating that the IR link is completed. If no action is taken during the three seconds of active data transfer, the receiver and the transmitter units do not link and transmitter’s previous program channel remains unchanged.

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 success-fully program the transmitter with the pre-programmed group and channel info from the receiver.

Manual Programming (GRP/CH and Volume):

The transmitter’s frequency is set using the Set Button (44) and then the (UP) or (DOWN) Buttons (43). To start, press the Set button once. The backlight on the LCD (36) will light up and the Group Icon (37) will flash. Use the or buttons to change the group. When a group selection is

finished, press the Set button again for the channel selection. The Channel Icon (38) will now flash. Again, use the or buttons to change the channel as desired. When the group/channel selection is done, press the Set button to enter volume level input setting and then press or to change in four steps from 0dB to -30dB (for loudest

input) or press the Set button a second time to exit to the main menu. To change volume

input level only, press the Set button three times to select the volume input level setting. Use the or to change in four steps from 0dB to -30dB (for loudest input). The level is preset at 0dB for GT and -10dB for LT/HM. These settings are optimal for most applications.

For normal operation, the transmitter should have the same Group/Channel as displayed on the receiver. After programming is finished, close the battery compartment door, ensuring that it latches. The BT-1KU is now ready for use.

BT-1KU Transmitter Switches

At Power Off the transmitter will store the last settings entered and re-display them at the next power on where it can be reprogrammed to any new Group/Channel. The default factory setting is Group 08, Channel 00.

The RF Power Level Switch (42) is used to select Hi/Low power transmission (see Operating the BT-1KU Handheld Transmitter).

When the Set Button (44) is pressed, the LCD main menu will cycle in this order:

MAIN MENU > GROUP > CHANNEL >

VOLUME > repeat

The selected function will flash for 20 seconds before returning to the main menu.

The (UP) or(DOWN) Buttons (43) work in the set mode only. They can be used to change any Group/Channel as selected (if not using IR Sync from receiver). They can also be used to select the desired Input audio level VOL setting.

13

Operating the BT-1KU

Bodypack Transmitter

During normal operation with the unit powered on, the transmitter power level can be changed by sliding the RF Power Switch (42) to “H” to increase the transmitted RF power (for longer range) or to “L” to decrease the RF power (reduced range). This is a useful feature as the “L” setting increases battery life and also optimizes the number of channels that can be used simultaneously in a given

location. Use this setting for normal use not requiring maximum operating range. A range walk test before use will determine which setting is best for your application.

The Power Off/Mute/On Switch (34) has three positions and functions both as a power on/off and as an audio mute on/ off switch. After the unit is powered on, slide the power switch to the on position to un-mute the audio. To mute/un-mute

the audio during use, set the power switch accordingly. The transmitter is now ready to use. Slide the On/Off switch to the on position and the microphone is now ready to use. The receiver’s RF Signal Meter (7) and Diversity A/B (3) indicators 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 Mute again. Adjust the volume of the receiver per Connecting Audio Output.

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

Note: The RF Signal meter and the Diversity A/B indicator on the receiver’s LCD display should be “On” in normal operation.

Instrument Use (BT-1KU/GT only)

Secure the connection of the GT (instrument) cable by lining up the slot of the 3.5mm mini connector and turning the ring to securely lock in. When ready to play, slide the Power Off/Mute/On switch (26) to ON position to un-mute the audio. Adjust the volume on the receiver for one-to-one unity gain (possible with Input Level set to 0dB only) 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.

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 mics are more resistant to feedback. However, they pick up sound sources best that are directly in front of the mic. Also mics that are farther from the sound source require more acoustic gain and thus are also more prone to feed back than close-source mics such as handheld.

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. For BT-1KU Bodypack transmitter, also confirm that the Power Off/Mute/On Switch (34) is not in the Mute position. The receiver’s Unbalanced Line Level Out (17) is adjustable so make sure the Volume (6) is set properly.

RF Interference and Finding Open Channels

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), often it can be overcome by adjusting the receiver‘s

Squelch Control (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.

See: Selecting the W-1KU Receiver Volume

Level / Group / Channel

Selecting the HT-1KU/BT-1KU Transmitter

Group and Channel

Programming the HT-1KU/BT-1KU to the Selected Channel

Programming the HT-1KU/BT-1KU with the Group/Channel Selected on the Receiver

To reprogram, you must first find an open channel. To do this, follow the operating procedure outlined in Selecting the W-1KU Receiver Volume Level / Group / Channel. With the associated transmitter off, scroll through the groups/channels to find one that shows no received signal on the receiver’s RF Signal Meter (7) (no bars). Also, there must be no bars either on each of the

three immediately adjacent channels both above and below the selected channel for optimum interference-free operation (i.e. in a field of seven adjacent channel

total—with the channel used in the middle). If operating multiple W-1KU Series systems simultaneously, repeat this procedure

with every new channel being selected, with previously tuned systems all on, both transmitters and receivers.

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.

Note: More bars in the Received Signal (39) icon indicate good signal strength in operation with the transmitter on, but more than 1 bar showing with the transmitter off also indicates the presence of likely RF interfering signals at that location. If this happens, select a different GRP/CH. One bar or less is ideal for interference-free operation.

Miscellaneous Tips

For optimum operation with external antennas, low loss RF shielded cable should be used and the length of the cable should not exceed 10’ (3 m).

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 optimum 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 brand new alkaline 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’ (1 m) as that may overload the receiver’s input circuitry and cause noises.

For the best operation, the receiver should be placed at least 3’ (1 m) above the ground and 3’ (1 m) away from a wall or metal surface. The transmitter should also be at least 3’ (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 BT-1KU 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.
