Performance Manual: Alternate Audio Hookups
The four AUDIO OUTPUTS marked "0", "1", "2", and "3" are used either as Effects Send/Receive, or to create stereo effects. Each of these outputs are selected from within a program as one of the program parameters. The signals on each of these output jacks normally is summed to the MONO OUTPUTS via the rings of these jacks. Therefore, inserting a mono plug into one of these output jacks will remove that signal from the mono mix.
To use an output jack as a Send/Receive jack, use a quarter-inch stereo plug and send the signal to the effect (such as phaser, reverb, etc.) from the tip of the plug, and route the output of the effect back into the ring. Whenever a program is selected with the OUTPUT SELECT  parameter set to this jack, the signals will automatically be routed out to the effect, and back into the mono mix.
To operate the Chroma in a stereo mode, first establish a LINK (see Performance Controls: TWO PROGRAM LINKAGE Switches). A LINK program divides the channels into two differently programmed groups which can be used for stereo. Then, press [SET SPLIT] and number  on the right panel. This will temporarily route the LINK channels to output "3" and leave the MAIN channels in the MONO OUTPUTS. (See illustration A.)
If you wish to use the balanced XLR output jacks for stereo, insert the Dummy Plug (supplied with the Chroma) into output "3" to remove it from the mono mix. (See illustration B.)
The full list of temporary output routings is:
- [SET SPLIT],  = Routes LINK channels to output "0".
- [SET SPLIT],  = Routes LINK channels to output "1".
- [SET SPLIT],  = Routes LINK channels to output "2".
- [SET SPLIT],  = Routes LINK channels to output "3".
