Brand new for 2003, the KAB Souvenir GTX offers advanced flexibility for processing recorded media. All your analog audio signals should pass through the GTX on their way to digital conversion and especially at the back end for the ultimate in mono mixing. Independent outputs also permit the creation of 4 channel mixes from stereo sources.
If time and experience has taught us
anything, it is that our precious record grooves are far from perfect.
- Disc cutters are not perfect
- The molding process, though impressive, is not perfect
- The artifacts of groove wear are inconsistent from
side to side
- The playback stylus and cartridge are not perfect
The monophonic record groove begins life as
a single groove, modulated laterally, or side to side. There are also
vertically cut mono recordings where the groove modulation is cut in a hill and
dale motion. These are less prevalent.
When you play back a mono recording using a
stereo cartridge and listen in stereo you can hear all these variables present
themselves in the soundstage.
- Left signal and noise
- Right signal and
- Left + Right signal and noise
- Left Right surface
- Right Left surface noise
Usually the first step towards
improving the sound is to simply combine the left and right channels with a
mono selector or mono cartridge. This goes a long way in reducing surface noise
by cancelling the Right - Left and Left - Right signals. But because the
quantities are not perfectly equal, then neither are the cancellations.
We can use the attributes of the stereo cartridge to our
advantage by first dissecting all these different signals. Then we can pit them
against each other in a way that produces the most optimum cancellation of
noise and distortion. And we call this process Groove Tuning In a stereo recording, the stereo blend control can be used to tighten the soundstage. The independent outputs can be used to dissect the individual signals for 4 channel surround sound:
The Inverse RIAA equalizer can be used to convert your phono signal to a flat eq or keep the RIAA bass boost and just flatten the treble portion. Restoration professionals prefer this EQ for it enhances noise reduction processing.
- Lateral I.E. Mono for center channel
- Vertical I.E. Ambience for rear channel
Isolate vocals or instrumental solos in stereo recordings. Can also be used to suppress vocals in many stereo recordings.
Connections are single ended RCA and active balanced TRS style connectors. Bypass is hardwired.
