Powering up
Your new Busker-10 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 (31) and
see if the power LED lights (30). If not, you will need to charge the battery before use away
from mains power.
Connect the Busker-10 unit to the mains using the appropriate IEC power lead supplied (29).
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 (20)
which lights when charging.
Note: it is recommended to store the PA unit at an ambient temperature and not with the
battery fully discharged.
You may otherwise opt to connect the DC input at the rear (21) to an external 12-15Vdc
supply (e.g car battery) or use the internal battery if charged.
When powered up, BASS and TREBLE controls (16, 15) should remain pointing vertically
(i.e. 12-o-clock position). Turn up the AUX/LINE VOLUME control (14) part way and switch
TALKOVER (25) off.
Your Busker-10 unit should now be ready to operate.
VHF Wireless Microphone
Extend the VHF antenna (22) at the rear of the unit. Insert batteries into the handheld
microphone by carefully unscrewing the base 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 control (2) up part way for checking.
Switch on the wireless mic and the signal indicator LED (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 control, testing the microphone 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 (18) 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-10’s own VHF microphone, two 6.3mm jack inputs (26, 27) are
provided to connect external wired or wireless microphones, which are both governed by the
WIRED MIC VOLUME control (17). 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 (28)
Also, twin RCA (23) and 3.5mm stereo jack input (24) 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 (13).
This can be fed on to further active speakers or portable PA units via a twin RCA lead.
Internal media player
Each Busker-10 portable PA unit has an internal media player for digital audio playback from
USB or SD/MMC media, FM tuner or via B/T wireless.
Press ‘Mode’ (7) to select the function required - USB, SD, FM radio (89-107) or B/T wireless.
 –Use this mode for both USB and SD/MMC cards
FM Radio –(the last chosen frequency will appear)
 –Use this mode for B/T wireless connection
Playback from USB Device or SD/MMC Card
Inserting a USB memory device into the USB connector or SD/MMC card into the SD/MMC card
slot will automatically load up and begin playback of mp3 or wma audio tracks stored on the
media.
If playback does not start, press the Play/Pause button (11) or remove the memory device and
check that the stored files are the correct compressed audio format before re-connecting.
PLAY/PAUSE (11) will alternately play or pause the selected track
PREVIOUS TRACK (10) will step backwards through tracks
Holding the PREVIOUS TRACK button will reverse seek through the current track
NEXT TRACK (12) will step forwards through tracks
Holding the NEXT TRACK button will forward seek through the current track
USB/SD (9) will toggle between USB or SD/MMC card media playback
REPEAT (8) will select between repeating  track or  tracks

178.864UK User Manual
FM Tuner
In FM tuner mode, the station frequency (in MHz) will be displayed.
For initial setup, press PLAY/PAUSE to begin the auto-tuning process.
The tuner will seek through all frequencies for strong signal reception (i.e. radio stations)
These will be stored into memory as , , , … etc.
Stored stations can then be selected using the PREVIOUS or NEXT buttons
Note: Pressing PLAY/PAUSE during auto-tune will allow manual tuning via PREVIOUS/NEXT
B/T Wireless Connection
Select ‘’ using the mode button (9). The B/T wireless symbol will be flashing if it is NOT
paired with an audio device.
Scan for B/T wireless devices on your phone or other B/T wireless enabled audio player and
check for a device called ‘bt-speaker’. Select this device and opt to connect your B/T wireless
device, which should then state that it is connected to “bt-speaker” for audio output.
The B/T wireless symbol on the Busker-10 unit should stop flashing to confirm the connection.
Play audio from your B/T wireless device and check for output through the Busker-10 unit.
If there is no output, check if there is more than one device within range called “busker-pa”
In the eventuality that more than one device is called “busker-pa”, try each device in turn until
the Busker-10 is found. Check also that the volume level is turned up on the sending device.
Once audio is playing through the Busker-10 from B/T wireless, adjust the MEDIA volume
control (7) to the required volume.
B/T wireless on the Busker-10 can only pair to a single device at any one time and should be
operable over a range of 5 to 8 metres.
