The L+R output meters (14) should light up and the sound should be heard through the connected speakers.
Increase the Master output level if required and set the relevant channel level control to the required volume.
Repeat the above steps for all connected inputs whilst balancing the levels between channels as required.
For the AUX line inputs, a single rotary control for each (9, 10) adjusts the level of both left and right RCA inputs.
Channel 1 input also has a priority function which attenuates all other channels when there is a signal on Ch.1
Turning the CH.1 override level control (29) clockwise increases the amount that it mutes all other channels.
Sensible use of the output meters (14) will help to avoid overdriving the amplifier outputs.
The +10dB LED should only light briefly on percussive or transient parts of the sound (i.e. bass drum)
If the +10dB LED is lit for any longer than short bursts, the level controls will need to be turned down.
This will avoid signal clipping and overdrive, which can be damaging to the speakers.
For overall tone adjustment, moving the BASS and TREBLE EQ controls (11, 12) can help to tailor the sound quality as required.
If the sound is too thin sounding, turn up the BASS rotary. If it is too deep sounding, reduce the BASS level.
If the sound is not very clear, turn up the TREBLE rotary. If it is too harsh sounding, reduce the TREBLE level.

The MM3260 built-in media player can play standard compressed audio files stored on a USB memory device (formatted to FAT32)
Insert the USB device into the USB port (2) to start playback using PREVIOUS, PLAY/PAUSE, NEXT & REPEAT controls.
The media player can also playback audio from a smart phone or tablet via B/T wireless connection.
To pair a device to the MM3260, press the SOURCE button until "bt" appears in the LCD display.
On the smart phone or tablet, search for the device called "adastra" and select to pair and connect.
Once connected, playback from the device can be navigated by the PREVIOUS, PLAY/PAUSE and NEXT buttons.
For FM tuner mode, press SOURCE until a frequency (in MHz) is displayed. Press and hold PLAY/PAUSE to auto tune available stations
(pressing PLAY/PAUSE during this process will abort the auto-tuning) Use the PREVIOUS and NEXT buttons to navigate through the stored stations.
To delete any selected station, press and hold the Repeat button. Repeat the auto tuning process to re-populate any missing presets.
Connecting an external device to the 3.5mm AUX jack socket (1) allows playback of stereo line level audio through the media player.
All media player output is controlled by the MEDIA level control (5) on the front panel.
Turn down the Master volume control before powering down the MM3260 mixer to avoid any loud noise through the speakers.
