Line/Sub Out

This is a full range line level signal useful for 
driving other CX-A / CXSub cabinets or 
mixers. This sub filter does not operate on 
the line out. (i.e. Lineout is always full range.)

Extension Loudspeaker

Should you need to expand your sound 
system additional 8 ohm speaker cabinets can 
be connected here. If 4 ohms cabinets are 
connected there is a high risk of thermal 
overload and potential damage to your CX-
A.

Power Inlet and Power Fuse

Connect the mains supply here. Ensure the 
local mains supply is compatible with this 
product.

Power Fuse

In the event the mains fuse blows only 
replace with same type and rating
Please refer to the product rear panel for 
details of the correct type and rating.  

Power Switch

This switches the product on /off. When the 
unit is on the Power led illuminates.

Inputs

The CXsub-A accepts line level signals on 1/4 
inch mono jacks. This allows the CXSub to be 
driven by a single mono jack or a stereo 
signal on 2 mono jacks or a stereo jack.

Level

This control allow you to set the balance 
between you CXSub cabinets and the rest of 
your sound system allowing you to make you 
CXSub quieter or louder.

Phase

This allows you the flip the phase of the sub 
though 180 degrees.
This is effectively the same as swapping the 
`+` and `-` connections on the loudspeaker. 
This allow you to ensure the CXsub and the 
bass driver in the mid/top cabinet are 
operating in phase with one another. If your 
bass drivers are out of phase with each other 
you will get bass cancellation.
 

Power

 the mains is connected and 

the CXsub is switched on.

Peak

 : Indicates that the onset of amplifier 

clipping - if this is on a lot - it won’t sound 
very good and the level control should be 
adjusted to reduce the volume . If it still 
needs to be louder additional speakers/amps 
are required.
