Sampling and Sample Editing
Sampling Digital Signals
The Þrst difference is the fact that there are no parameters for gain and sample rate. ThereÕs no
need for a gain parameter because with digital sampling, since youÕre making an exact digital
copy of the source signal. The Rate parameter is excluded because the K2600 automatically
recognizes the source sampleÕs rate and sets its own rate accordingly. Also, the Mon parameter
does not appear when sampling digitally. Any monitoring you wish to do must be done from
the sample source.
Cable
Set the Cable parameter to a value of Coaxial or Optical, depending on the type of cable youÕre
using. Many consumer products with digital output provide an optical jack. There is a small
plug covering the K2600Õs optical input; this plug must be removed before you can connect the
optical cable to the K2600. The plug should be replaced whenever the optical input is not in use.
If you plan to use a coaxial cable, select a value of Coaxial for the Cable parameter. If youÕre
sampling from a consumer product like a CD player, youÕll probably need to get an adaptor, or a
cable with an RCA Þtting on one end and an XLR (male) Þtting on the K2600 end. Some
professional products have an XLR Þtting for their outputs, so an ordinary microphone cable
will be suitable in most cases. Longer cables can cause signal loss, however, so if you need a long
cable, you may need to get a special cable designed for digital information transfers. ThereÕs
detailed information about cables for sampling on page 14-1.
Format
Use the Format parameter to tell the K2600 the format of the incoming sample. Most consumer
products use SPDIF (Sony/Philips Digital Interface Format), while most professional machines
use the AES/EBU (Audio Engineering Society/European Broadcast Union) format. Refer to the
ownerÕs manual of your sample source for information regarding its digital format.
The Mode, Time, and Thresh parameters function for digital sampling just as they do for analog
sampling.
If the K2600 detects an incoming clock signal, the display shows LOCK, and the sample rate of
the signal. If you donÕt see LOCK, youÕre not getting signal, and you wonÕt be able to sample.
The K2600 automatically sets itself to the clock rate it detects. (For sample rates other than 48,
44.1 and 32, the rate doesnÕt show in the display, but the K2600 still samples the input correctly.
You might need to adjust the coarse tune to get the proper root pitch.)
Src
When Input is set to Digital on the SampleMode page, the Src parameter appears only if you
also have the digital I/O option. ItÕs the same parameter that appears when Input is Analog.
Use a value of Int for Src when you want to sample the K2600Õs Mix output. Use Ext when you
want to sample an external source via the coaxial or optical stereo digital input jacks.
If you have the digital I/O option, Src has another value: Return (Rtn). This enables you to
sample a two-channel return from KDS Out A (this requires a Kurzweil DMTi or other device
thatÕs compatible with KDS digital format).
Out
This parameter appears only if you also have the digital I/O option. It doesnÕt really have
anything to do with sampling; it determines how the K2600 handles its digital audio output. See
Chapter 19 for information about using the digital audio outputs.
