Powering up
Your new Busker 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
see if the power LED lights (29). If not, you will need to charge the battery before use away
from mains power.
Connect the Busker unit to the mains using the appropriate IEC power lead supplied (24).
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 a CHARGING LED (31)
which lights when charging.
You may otherwise opt to connect the DC input at the rear (32) to an external 12-15Vdc
supply (e.g car battery) or use the internal battery if charged.
When powered up, BASS and TREBLE controls (17, 18) should remain pointing vertically
(i.e. 12-o-clock position). Turn up the AUX LINE control (19) part way and switch TALKOVER
(25) off.
Your Busker unit should now be ready to operate.
VHF Wireless Microphones
Extend the 2 VHF antennas (23) at the rear of the unit. Insert batteries into the handheld
microphones by carefully unscrewing the base of each and connecting the “+” and “-”
terminals of the batteries to the corresponding contacts inside the mic body, taking care to
observe the correct polarity. Turn the VHF 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 VHF VOL controls, testing each microphone in turn for output through
the speaker.
Take care not to incur “feedback” (howling or screeching sound through the speaker) by
keeping the microphone a sensible distance from the speaker and pointing away from the
speaker so that it doesn’t hear the speaker output.
Turning the ECHO control (15) clockwise adds an echo function for singing or special effects.
The BASS or TREBLE tone of the RCA and Guitar inputs can be cut by turning the relevant
control anti-clockwise or boosted by turning clockwise.
When not in use, switch the wireless microphones off and remove batteries if not being used
for long periods.

External Inputs
In addition to the Busker’s own VHF microphones, two 6.3mm jack inputs (20, 21) are
provided to connect external wired or wireless microphones, which are both governed by the
WIRED MIC VOL control (16). If required, the music level can be automatically muted when
speaking into a microphone by switching in the TALKOVER feature on (25)
A further 6.3mm jack input is provided for an electric or electro-acoustic guitar (22)
Also, twin RCA and 3.5mm stereo jack input are provided for line input sources such as a CD
player or smart phone. These are both independent of the media player.
Adjacent to the twin RCA input is a twin RCA line output carrying the overall main mix. This
can be fed on to further active speakers or portable PA units via a twin RCA lead.
Internal media player
Each Busker portable PA unit has an internal media player for digital audio playback from USB
or SD/MMC media, FM tuner or via Bluetooth.
