Playing audio using Bluetooth
You can use many Bluetooth devices to play
audio through the M20 system. Firstly you will
have to pair your Bluetooth device with the
speaker using the following instructions.
1. Press and hold the Bluetooth input button
on the remote control until the blue LED
ashes on the speaker. Alternatively, press
the Bluetooth button on the back of the
amplied speaker, the LED will ash blue.
2. Select the Bluetooth settings on your device,
and look for Q M20 HD in devices.
3. Select the M20 HD device in the new
Bluetooth device list.
Once connected, the LED will stop ashing and
remain on blue.
4. You can now play audio from your device.
Once you have paired a device, you can simply
connect to the M20 next time which will turn on
and select the Bluetooth input.
When playing audio, you can use the device, the
remote control or the buttons on the amplied
speaker to alter the volume. You can also use the
remote control to play, pause and skip tracks.
Clearing the Bluetooth pairing list
You can clear all the devices from the Bluetooth
pairing list memory if required by using the
following steps:
1. Put the speakers into Bluetooth pairing mode
with a long press of the BLU source button on
the remote control, the LED will be ashing
Blue.
2. Press and hold the BLU source button on the
remote control again, until the LED goes out
and then ashes three times.
The Bluetooth pairing list is now cleared from the
memory and devices must pair again in order to
connect.
Connecting between the speakers
Firstly, connect the supplied speaker cable
between the amplied and passive speaker. The
wires are coloured dierently to identify + and -
polarity. Ensure you always use the gold wire for
+ and silver wire for – at both ends.
Port damping
The M20 speakers are rear ported and designed
to work best with some space behind them i.e.
200mm or so away from a wall. If you position
your speakers close to a wall / corner then the
foam plugs should be inserted into the rear ports
or there could be too much bass.
• Ensure the plugs are tted snugly into the
port without inserting them too far.

You can use the remote control or the buttons on
the amplied speaker to alter the volume.
Speaker positioning and assembly
Simply place the speakers either side of the main
listening position on an appropriate at surface,
ideally about 2.0 – 4.0m (2-4 yards) apart.
Alternatively you can use M20 with the Q
