MO' BASS - GETTING STARTED

Connecting Your Speaker Cabinets

The Mo' Bass speaker outputs can be run in either stereo or bridged/mono modes by using the stereo/mono selector switch
on the back panel. For most situations the obvious is true: if you plan on using two speaker cabinets, run the Mo' Bass in
stereo. If you plan on using one speaker cabinet, run the Mo' Bass in mono. MAKE SURE that the stereo/mono selector
switch correlates with your desired setup. Also keep in mind that the Mo' Bass delivers 900 watts into one 4 ohm speaker
cabinet in bridge mode. Make sure that your speaker cabinet can handle the power listed in the "Power Ratings" section of
the "Mo' Bass Specifications" section of the manual.

Using One Speaker Cabinet

First, locate the "Speaker Outs" section on the rear panel of the unit. Put the stereo/mono selector switch in the "mono"
position. Connect the Speakon-to-Speakon speaker cable from the "Bridged Output" jack on the Mo' Bass to your speaker
cabinet. You will notice that both the left and right Master Volume controls on the front panel are active and will affect the
overall level even though you are in bridged/mono mode. This is normal. The impedance of your single speaker cabinet
must be no lower than 4 OHMS in bridged/mono mode.
Important: Be sure that your single 8 ohm speaker cabinet can handle at least 650 watts, and that your single 4 ohm
speaker cabinet can handle at least 900 watts. If not, it is safer to run your low-power-rated single speaker cabinet in stereo
mode off of the right speaker output.

Using Two Speaker Cabinets in Stereo Mode

Put the stereo/mono selector switch in the "stereo" position. Connect a speaker cable from either the left 1/4" or Speakon
speaker out jack to one speaker cabinet, then do the same for the right side. The Left and Right Master Volume controls
should correlate to the cabinets on each side.
If the cabinets are the same impedance, the same amount of power will be sent to each enclosure. If the cabinets are
different impedances, more power will flow to the cabinet with the lower impedance, and you should adjust the left and right
Master Volumes to achieve equal levels. Again, make sure to check the power handling capabilities and impedances of the
speaker cabinets you wish to use against the "Power Ratings" section of the "Mo' Bass Specifications" section of the
manual.
Using Two Speaker Cabinets in Bridge/Mono Mode
If you don't want separate output signals routed to different enclosures, and you are using speaker cabinets with input and
output jacks, you can "daisy chain" the enclosures together to achieve full potential of the power amps in bridged/mono
mode. Put the stereo/mono selector switch in the "mono" position. Then connect a speaker cable from the "Bridged Output"
jack on the Mo' Bass to the input jack of your first speaker cabinet. Then, to complete the "daisy chain", connect another
speaker cable from the output jack of your first cabinet to the input jack of your second cabinet. As when using one speaker
cabinet in bridged/mono mode, both Master Volume controls are active.
Important: The minimum total impedance when operating Mo' Bass in bridged/mono mode is 4 Ohms. This means that you
can use two 8 ohms enclosures safely, but when in bridged/mono mode you CANNOT use:
a) two 4 ohm enclosures (2 ohm load)
b) an 8 ohm and a 4 ohm enclosure (2.67 ohm load)
If your system falls into either of the categories above, you should run the Mo' Bass in stereo mode and connect the speaker
cabinets accordingly.
More details are available in the "Speaker Outputs" section of this manual, and we strongly recommend that you read the
entire manual. However, this should be enough information to get you started.
