Operation

Connect any line input (CD, mp3 player, home keyboard etc.) to the QXBT speaker via the 6.3mm jack line input (12) or alternatively, connect a microphone to the XLR mic input (11)
Turn the VOLUME control (7) fully down and turn the POWER switch (3) on. BASS and TREBLE controls (8, 9) should remain pointing vertically (12-o-clock position).
Turn up the VOLUME control part way and test the input signal (line or microphone) for output through the speaker. Adjust the VOLUME to the required output level and TREBLE and BASS controls to adjust the overall tone of the output (clockwise to boost, anti-clockwise to cut).

Bluetooth™ Connection

QXBT units are fitted with a Bluetooth receiver, which is operated via a rotary control (4) and play button (5) on the rear panel. When the rotary control is turned fully off, the power to the Bluetooth receiver is off.
If switched off, turn the Bluetooth rotary control clockwise to switch power on to the Bluetooth receiver. Turning the rotary control up increases Bluetooth output level – halfway is a reasonable position to start. Press and hold the Bluetooth play button for 3 seconds and the Bluetooth indicator (6) will flash blue. If the playback source is already paired, the connection will be made with the QXBT speaker and a chime will sound to confirm this.
If not paired, press the play button briefly again to see the LED flash between blue and red. At this point, the Bluetooth receiver is made visible to all Bluetooth devices in range. Scan for Bluetooth devices on your playback source and check for a device called “Bluetooth” (lower case). Select this device and opt to connect and your sending device should state that it is connected to “Bluetooth” for audio output and the LED should flash blue and a beep will confirm the pairing. Play audio from your sending device and check for output through the QXBT speaker.
If there is no output from Bluetooth, check if there is more than one device in a range called “Bluetooth” In the eventuality that more than one device is called “Bluetooth”, try each device in turn until the QXBT unit is found. Check also that the volume level is turned up on the sending device.
Once the audio is playing through the QXBT speaker from Bluetooth, adjust the rotary control (4) to the required volume.
The QXBT speaker’s Bluetooth receiver has duplex Play/Pause control over the sending device. Press the Bluetooth button on the rear panel to remotely pause or resume playback from the sending device. This is useful when the audio is played from a phone in a pocket or on an armband or from a PC or Mac computer.
Bluetooth on the QXBT speaker can only pair to a single device at any one time and should be operable over a range of 5 to 8 meters.
Turning the rotary control fully down clicks the power off and shuts down the Bluetooth receiver.
