Stereo keyboard with monitors - 

Connect to the Trim-Two 

using standard ¼” coaxial cables and XLRs for the PA sys-

tem. If you are adding personal monitors, use a set of RCA 

to ¼” cables to feed the powered monitors. This essentially 

uses the RCA connectors as a typical THRU. Note that the 

THRU outputs will not be affected by the Trim-Two Level 

control. In other words, your keyboard volume control will 

determine the sound going to your monitors. Start by setting 

this up so that it is comfortable for you and then set the level 

control for the PA. 

Controller keyboard with laptop - 

More and more key-

board players are using a laptop to generate audio fi les and 

‘play’ the computer using a controller keyboard with a USB 

port. Connect the output from the laptop to the Trim-Two us-

ing the 3.5mm connector. Use the XLR outs to feed the PA 

and the ¼” outputs to feed the monitors on stage. 

Using the Trim-Two for a DJ setup - 

DJ mixers can be no-

toriously problematic due to the DJ being too loud. This can 

cause distortion or even harm the PA system. Connecting 

the DJ mixer to the Trim-Two enables you to set a maximum 

level and is quick to adjust should need be. Connect a de-

vice to the Trim-Two using the RCA or ¼” inputs.
