Busker-12U & Busker-15U User Manual
Powering up
Your new Busker-U portable PA unit may arrive with you with the internal battery charged.
Before connecting to the mains, turn down all volume controls and switch the unit on (30) and
check to see if the power LED above the switch is lit. If not, you will need to charge the
battery before use away from mains power.
Connect the Busker-U unit to the mains using the appropriate IEC power lead supplied (33).
When not in use but connected to the mains, if the POWER switch is in the OFF position, the
internal battery will be re-charged from the mains supply, indicated by the battery status LEDs
(29) which indicate when the unit is charging and the level of charge in the battery.
You may otherwise opt to connect the DC input at the rear (31) to an external 12Vdc supply
(e.g. car battery) or use the internal battery if charged.
When powered up, the TREBLE, BASS, MIC. TREBLE & MIC. BASS controls (15, 16, 17, 18)

observe the correct polarity. Turn the UHF MIC controls (2, 3) up part way for checking.
Switch on each wireless mic in turn
–
the signal indicator LEDs (1) on the front of the unit
should light as a result. If the LED on the transmitter lights dimly, change the battery.
Gradually increase the UHF VOL controls, testing each mic for output through the speaker.

keeping the microphone a sensible distance from the speaker and pointing away from the
speaker so that it doesn’t
hear
the speaker output.
