Powering up
Your new QUEST 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 (25) and
see if the power LED lights. If not, you will need to charge the battery before use away from
mains power. Connect the QUEST unit to the mains using the appropriate IEC power lead
supplied (26).
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 charging and battery
status LEDs (11).
You may otherwise opt to connect the DC input at the rear (12) to an external 12-15Vdc
supply (e.g car battery) or use the internal battery if charged.

When powered up, BASS and TREBLE controls (20, 19) should remain pointing vertically
(i.e. 12-o-clock position). Turn up the MASTER VOLUME control (18) part way and switch
TALKOVER (24) off.
Your QUEST unit should now be ready to operate.
VHF Wireless Microphones
Extend the 2 VHF antennas (13) 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 VOL controls (9, 10) up part way for checking.
Switch on each wireless mic in turn –the signal indicator LEDs next to the VHF volume
controls should light. If the LED on the transmitter lights dimly, change the battery. Gradually
increase the VHF MIC VOL controls, testing each 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 (4) clockwise adds an echo function for singing or special effects.
The BASS or TREBLE (20, 19) content 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 Quest’s own VHF microphones, two 6.3mm jack inputs (7, 8) are provided to
connect external wired or wireless microphones, which are both governed by the WIRED MIC
VOL control (5). If required, the music level can be automatically muted when speaking into a
microphone by switching in the TALKOVER feature on (24)
A further 6.3mm jack instrument input is provided for an electric or electro-acoustic guitar (6),
controlled by its own volume control (3)
Also, twin RCA (22) and 3.5mm stereo jack input (23) 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 (21) carrying the overall main mix.
This can be fed on to further active speakers or portable PA units via a twin RCA lead.

FM Tuner
In FM tuner mode, the station frequency (in MHz) will be displayed.
For initial setup, press PLAY 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 during auto-tune will allow manual tuning via PREVIOUS/NEXT
Bluetooth™ Connection
Select ‘’ using the MODE button (9).
Scan for Bluetooth™ devices on your phone or other Bluetooth enabled audio player and check
for a device called ‘QUEST’. Select this device and opt to connect your Bluetooth device, which
should then state that it is connected to “QUEST” for audio output.
Play audio from your Bluetooth™ device and check for output through the Quest PA unit.
If there is no output, check if there is more than one device within range called “QUEST”
In the eventuality that more than one device is called “QUEST”, try each device in turn until
the Quest PA is found. Check also that the volume level is turned up on the sending device.
Once audio is playing through the Quest PA from Bluetooth, adjust the MEDIA volume control
(7) to the required volume.
Bluetooth on the Quest PA can only pair to a single device at any one time and should be
operable over a range of 5 to 8 metres.
