BT-8U Bodypack Mic Transmitter

1.Snap open the BATTERY DOOR (13) and insert a fresh 9V alkaline or NiMH battery into the BATTERY COMPARTMENT (14) observing the correct polarity. Close the battery door to its original position and completely cover the battery. Fresh alkaline batteries can last up to 10 hours in use, but in order to ensure optimum performance, it is recommended that the battery be replaced after 6-8 hours of use. A NiMH battery should be replaced with another recharged fully (with separate charger, not supplied, and as per its charging instructions) whenever low or dead battery status is indicated as per the following.

2.Selecting Audio Input Operating Mode: The BT-8U is equipped with two INPUT SELECTOR SWITCHES (15) located under the cover on the circuit board for selecting the type of audio input you will be supplying to the transmitter. Select from the choice of three positions: INSTRUMENT (for guitar, bass, etc.), HEADWORN MIC, and LAVALIER MIC (Condenser Microphones).

(Note: Use only the input audio source as per the input selected with the internal AUDIO INPUT SELECTOR SWITCHES (15) or the audio will not be optimal–a muddy or distorted sound may result.)

There are two switches with selectable positions GT, HM, LT together at the same time.

To select inputs: (see chart on page 9)

A. Instrument: Set both switches to GT

B. Headworn Mic: Set both switches to HM

C. Lavalier Mic: Set both switches to LT

3.Connecting for Selected Input: The BT‑8U is provided with a 3.5 mm LOCKING JACK (16) for connecting the audio input selected. Connect either the INSTRUMENT CORD (17) or the HEADWORN MIC (18) or LAVALIER MIC CORD (19) as desired, according to the input

selected. To secure the connection, turn the slip ring on the plug clock wise to thread it on the jack. To unplug, reverse the process. Slip the transmitter into a pocket or CLIP

(20)it on to your clothes or instrument strap (if using the BT-8U as an instrument transmitter).

4.Turn on the BT-8U by sliding the OFF/ STANDBY/ON SWITCH (21) to the STANDBY position (transmitter on, audio muted) or the ON position (transmitter and audio both on). The BATTERY INDICATOR LED (22) will give a single quick flash, indicating usable battery strength. In the case of a dead or low battery, the LED either will not go on at all or will stay on continuously, indicating that the battery should be replaced with a fresh one. To conserve battery life, turn unit off when not in use.

5.The BT-8U transmitter is now ready

to use. The SIGNAL LED (5) on the DKW-

8U receiver should now be lit, indicating a received signal from the transmitter. Adjust the volume of the receiver as per the Connecting the Audio Output of the above DKW-8U receiver instructions.

6.Instrument Use: Secure the connection from the GT CABLE (17) by turning the slip ring on the plug into the transmitter clockwise to thread it on the jack. To unplug, reverse the process. Plug the 1/4” phone plug into the instrument. When ready to play, slide the audio OFF/STANDBY/ ON SWITCH (21) to either “STANDBY or ON” position. Adjust the volume of the receiver as per the Connecting the Audio Output of the above DKW-8U receiver instructions.

(Note: The INPUT LEVEL CONTROL (23) is deactivated and not used when the BT-8U is in INSTRUMENT (GT) mode. Levels should be adjusted with the volume control of your instrument.)
