Power connection and internal battery

Your new MIXCAB-15 unit may arrive with you with the internal battery charged.
Before connecting to the mains, turn down all volume controls (17, 20, 23) and switch the unit on (26) and check the battery level indicators (25). If the battery level is low or if no LEDs light at all, you will need to charge the battery before operating away from mains power.
Connect the MIXCAB-15 unit to the mains (27) using the appropriate mains IEC lead supplied. You may otherwise opt to connect the DC input at the rear (14) to an external 12-15Vdc supply (e.g car battery) or use the internal battery if charged.
If the POWER switch is in the “off” position whilst the unit is connected to the mains, the internal battery will be re-charged from the mains supply. The battery status LEDs will be off and the “CHARGING” LED will light red when charging or green when fully charged.

Note: it is recommended to store the PA unit at an ambient temperature and not with the battery fully discharged.

Connection & Setup

When powered up, all BASS and TREBLE controls (21, 22) should remain pointing vertically (i.e. 12-o-clock position). Also turn down all ECHO controls to begin with (13, 19)
If the MIXCAB-15 is to be used on its own without connecting an XCAB-15 extension speaker, it is best to operate the unit in mono to avoid losing one side of the stereo mix. Slide the mono/stereo switch (24) to the MONO position.
If the MIXCAB-15 is to be operated with an XCAB-15 extension speaker (or equivalent), connect the extension speaker to the XCAB-15 output (15) using an SPK or Speakon® lead. For stereo operation, slide the mono/stereo switch to the STEREO position.

Note: this output is suitable for a 4Ω or 8Ω speaker with a power handling of 150Wrms.
Input channels 1, 2 and 3 can accept microphone or line inputs by either XLR or 6.3mm jack (3, 5, 7). If a microphone is connected to an input channel, slide the relevant mic/line switch to the MIC position (4, 6, 8). If a line input is connected (such as CD player, mp3 player, laptop, TV decoder etc.), slide the relevant mic/line switch to the LINE position.

Musical instruments such as keyboards, electronic drums and guitars with preamps can also be connected as line inputs. Ensure that the mic/line switch is set to LINE for these.
Input channel 4 can accept a stereo line level input, which can be connected via Left + Right RCA sockets (9) or a 3.5mm stereo jack (10)

To connect the output signal from the MIXCAB-15 to further active speakers or amplifiers, a stereo line output is provided on Left + Right RCA sockets (11)

Operation

Before operating at full volume, it is important to make initial checks that input channels are connected and working properly.
To check a microphone that is connected to an input channel, turn up the MASTER VOLUME (23) part way and gradually increase the VOLUME control (20) for that input channel whilst speaking into the microphone. Check for sound coming from the MIXCAB-15 and increase the VOLUME control to the required level.
To check a line level signal that is connected to an input channel, as above, gradually increase the VOLUME control for that input channel whilst playing the signal into the input. Check for sound coming from the MIXCAB-15 and increase the VOLUME control to the required level.
Repeat the above for all 4 input channels and set the MASTER VOLUME to the maximum required level, using each channel VOLUME control to balance the levels of each within the overall output mix.

Each input channel has BASS and TREBLE EQ controls (21, 22), which are neutral when set to the vertical 12 o’clock position. To reduce the BASS or TREBLE frequency content for an input channel, turn the respective control to the left. To boost the BASS or

TREBLE frequency content for an input channel, turn the respective control to the right.
In addition to EQ controls, each channel also has an individual ECHO control (19) which varies the amount of the internal echo effect applied to that input. To enable the echo effect, slide the ECHO switch (12) to the ON position and turn up the ECHO VOL control (13) part way.

Increase the ECHO control (19) for the input channel gradually whilst speaking into the microphone or playing the line level signal into it. The echo effect should now be audible through the speaker. Set the main ECHO VOL control to the maximum required amount of echo effect and adjust for each channel using its own ECHO control.

Internal media player

The MIXCAB-15 unit has a media player for digital audio playback from USB or SD/MMC media FM tuner or via Bluetooth. The player can also be used to record audio to a USB or SD card. Turn the media player volume control (17) up to hear the output through the speaker

Press MODE to select the required function: USB, SD, REC, FM radio (89-107) or Bluetooth

Recording to USB or SD media

When in USB or SD card mode, the overall mix output of the MIXCAB-15 can be recorded to a memory device that is connected to the internal media player. The memory device may be USB or SD card (whichever is inserted first).

Press the MODE button to select REC mode , then press Play/Pause (to begin recording. The overall mix will now begin recording as a file on the storage device. Press Play/Pause  again to stop recording.
(note: if both USB & SD are connected, then repeated pressing of the MODE button to loop through all options back to REC mode will then default to writing to the SD card)

To play back the recorded file(s), press and hold Play/Pause for 3 seconds and the recorded file(s) will be displayed. Then, navigate to the required file and press Play/Pause for playback.

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

Bluetooth Connection

Select Bluetooth using the MODE button.
Scan for Bluetooth devices on your phone or other Bluetooth-enabled audio player and check for a device called ‘MIXCAB’. Select this device and opt to connect your Bluetooth device, which should then state that it is connected to ‘MIXCAB’ for audio output.
Play audio from your Bluetooth device and check for output through the MIXCAB-15 unit.
If there is no output, check that the correct ‘MIX CAB’ Bluetooth ID is paired and that the media volume control and master volume control are turned up.

In the eventuality that more than one device is called ‘MIXCAB’, try each device in turn until the correct one is found. Check also that the volume level is turned up on the sending device. Once audio is playing through the MIXCAB-15 from Bluetooth, adjust the media volume control (17) to the required volume.
Bluetooth on the MIXCAB-15 can only pair to a single device at any one time and should be operable over a range of 5 to 8 metres.

Media player remote control
