KB3 Effects
In the K2500Õs KB3 mode, KDFX processing is being used to its utmost. Several Studios have
been included for use with KB3, which have a special characteristic: the insert and Aux FX
buses are made to be used together, forming a "virtual" single processing Algorithm with 7
(count Õem) PAUs.
There are two Algorithms that are designed for this special use: Algorithm 735 (to be used on an
Insert FX Bus) and Algorithm 736 (to be used on the Aux bus). They donÕt work very well
individually, and should probably not be used that way. The ROM FXPresets that use these
Algorithms are 779 and 780, respectively.

Using the Internal Effects

The original Internal Effects processor on the K2500 is in the signal chain after the KDFX Studio.
It is only connected to the ÒMixÓ analog physical outputs (not to be confused with KDFXÕs Mix
bus output). Without KDFX, all sounds assigned to the ÒAÓ outputs go through the Effects
processor on their way to the Mix physical outputs (analog only). With KDFX, this is still true,
although sounds Þrst go through KDFX and then are assigned to the A output pair on the
StudioÕs Output page.
As always, if there are any plugs inserted into the ÒAÓ physical outputs, the A signal is
disconnected from the Mix outputs, and the Effects processor will not be heard. This is true of
all of the outputs: inserting a plug into any of them disconnects that pair from the Mix outputs.
See chapter 18 of the K2500 Performance Guide for more information.
