CABINET POSITIONS

This multifunctional and portable cabinet has three modes of operation and sound projection depending on the application and the place where you work. Thanks to internal switches and equalizers, the system changes the response curve automatically to maintain optimum balance in each position.
Elevated Surface
Place the speaker on a raised surface or on a speaker stand. This position allows greater projection of sound in full range to the audience.

Inclined
This position is especially used when both the artist and the audience are standing and in a close-up shot or when the audience is sitting in a shot in which the cabinet radiates
sound directly to them. In addition,the artist will also have a good reference of what he is playing and singing.

Monitor
this cabinet has the option of being used as a floor monitor or for a DJ, by tilting it sideways.

 CONNECTING DIAGRAM

Active, Full-range, two speakers. It is similar to the passive example but you do not need a power amplifier between the mixer and the two 6.5” speakers. Make all initial connections with all the equipment powered off, and ensure that all the main volume controls are turned down completely.

• Connect one side of the signal cable at your mixer into the Output Left/Right(with Stereo Jack or XLR) and the other side of the cable into the Line Input(COMBO) of your active speaker cabinet (with Stereo Jack or XLR).
• Connect the power cord to main.
• Turn ON your mixer first, then the active speaker cabinets.
• Turn up the volume control of the cabinets.
• Use PEL function to get the proper input level for the mixer, and adjust the Main Mix Level control to reach the desired output level.
• After use, turn off your active speaker cabinets first, then the mixer.
