UB-4 Bodypack Microphone Transmitter

1.Snap open the BATTERY DOOR (22) and insert a fresh 9V alkaline battery into the BATTERY COMPARTMENT (23), observing the correct polarity. 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.

2.The UB-4 is equipped with two INPUT SELECTOR SWITCHES (24) 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/ LAVALIER MIC. (G/H/L).

There are two switches, one with selectable position G, H, L and the other with G, HL. To select inputs: (see chart on page 10)

A.Instrument — both switches to “G”

B.Headworn Mic — set one switch to “H” and the other to “H”

C.Lavalier Mic — set one switch to “L” and the other to “L”

3.The UB-4 is provided with a 3.5 mm LOCKING JACK (25) for connecting the audio input selected. Connect either the INSTRUMENT CORD (30) or the HEADWORN MIC

(31)or LAVALIER MIC CORD (32) as desired, according to the input selected. (Note: Use only the input audio source as per the input selected with the internal AUDIO INPUT SELECTOR SWITCHES (24) 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 clock wise to thread it on the jack. To unplug, reverse the process. Slip the transmitter into a pocket or CLIP (29) it on to your clothes or instrument strap (if using the UB-4 as an instrument transmitter).

4.Turn on the UB-4 by sliding the OFF/STANDBY/ON SWITCH (26) to the STANDBY position (transmitter on, audio muted) or the ON position (transmitter and audio both on). The BATTERY INDICATOR LED (27) 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.

5.The UB-4 transmitter is now ready to use. The A or B DIVERSITY LED INDICATORS

(13)on the UHF-4 receiver should now be lit, indicating a received signal from the transmitter. Adjust the volume of the receiver as per the Audio Output Instrument Connections section of the above UHF-4 receiver instructions. For optimum performance, an INPUT LEVEL CONTROL (28) is provided on the top panel of the UB-

4.Adjust the gain by turning the control with a small slot head screwdriver.

It is recommended that this control be turned to maximum gain. However, for ultra high-gain instrument sources such as active bass pickups or even extra hot guitar pickups, turning the level down slightly will create a cleaner sound. (Note: Turning down the input gain too much can compromise the signal-to-noise ratio and is not recommended. Set for the maximum possible gain and headroom without noticeable distortion on the high level peaks).

The AF LEVEL LED DISPLAY (13) on the UHF-4 receiver will light up to 5 LEDs (4 green and 1 red) for all input signals. Occasional flickering on and off during use of the top red LED indicator in this display is normal, however if the red LED stays on continuously, turn down the instrument volume or adjust the INPUT LEVEL CONTROL

(28)on the UB-4 transmitter, or noticeable distortion may result.
