APPENDIX: DSP
The DSP comes with eight effects:
1. Shimmer Reverb
2. Stereo Delay
3. Stereo Delay + Reverb
4. Plate Reverb
5. Chorus
6. Vibrato
7. Phaser
8. AutoWah
On the faceplate you can choose between two of them (see above).
We configure the MARK II Preamp so you can switch between Shimmer Reverb and Stereo
Delay.
Anyway if you wish to change those programs please follow these steps:
- Remove the preamp from the namerail.
- Remove all potentiometer knobs.
- Loosen all potentiometers. Unscrewing is not necessary!
- Loosen both Accessory-jacks. Unscrewing is not necessary!
- The switches can be left mounted.
- Now you can remove the shielding case by pulling it up.
- On the right side on the PCB you will see two pinheaders with one jumper on each.
- The left pinheader sets the effect for “I” on the frontpanel.
- The right pinheader sets the effect for “II” on the frontpanel.
- Each position on the pinheader stands for one program.
- By changing the position of the jumper you can change the program.
For testing purposes it is okay to leave away the shielding case. Tighten all potentiometers and
accessory-jacks. Now you can try the different effects and see what you prefer. If you have
made your decision, please follow the steps above in reverse order.
APPENDIX: Power-Up Delay
The MARK II Preamp comes with an electronic power-up delay to prevent audible pops. It
takes about two seconds after power on for it to boot.
