Software Changes in OS 4.1
You will notice the following software changes when you load the 4.1 (or higher) K2600 Operating System. Some
of the parameters listed here will only display if you install the ADAT Digital I/O Option.
EditProg:KEYMAP Page
For the PlayBackMode parameter, KDS In 1 through KDS In 8 change to ADAT In 1 through ADAT In 8 .
KDFXMode:CTRL Page
Dither has moved to the MAST2 page (see description below).
DigOut (digital word length) is now selected on the MAST2 page. The parameter is now called Dig OutLen .
SampleMode Page
The Cable parameter is no longer provided, since (with the ADAT Option installed) all digital inputs to the K2600
are optical.
The Src parameter no longer offers Return ( Rtn ) as a choice (with the ADAT option installed). This was only used
in conjunction with the DMTi.
The Out parameter (used with the DIO-26) has moved to the MAST2 Page and is now called AESOut (see descrip-
tion below) .
MAST2 Page
There are several new parameters on the MAST2 page (Master Mode). The new parameters are described in the
following section.

Dither
This parameter was formerly on the KDFXMode:CTRL Page.
Dithering adds a small bit of noise to a digital signal to lower quantization distortion. Use the Dither parameter to
select different digital noise floor characteristics. No setting is superior to another—each one is a tradeoff between
perceived noise level and artifacts.
The 24 bit output is always undithered.
Flat —the digital noise floor is spectrally flat, so it’s a good choice for resampling the K2600’s own output, as there
will be no addition of noise in the process. This is sometimes known as triangular dither.
