Is the Patchulator 8000 balanced/stereo or unbalanced/mono?
It is a balanced/stereo patchbay, meaning that all jacks and the mini patch cables are TRS. You can certainly use it to patch mono signals, which is the most common scenario, just be sure to use mono TS 1/4-inch cables to connect to your gear. Note: Some older units are mono TS only. If you are unsure about yours, open the unit. Circuit boards inside indicates it is TRS stereo capable, hand-wiring is TS mono only.
What are the advantages of using the Patchulator 8000 versus a typcial rack-mounted patchbay?
It certainly depends on your scenario, but the Patchulator 8000 is unique in its size and portability, which allow it to be localized right next to your effects and instruments. This means shorter cable runs and immediate accessibility.
Is the Patchulator 8000 DC-coupled for use with control voltage modulation signals?
No, but it does not matter. It is a passive device that simply directs signals, just like an audio cable. It is perfectly ok to patch low-voltage control signals into and out of the unit.
Does the Patchulator 8000 accept guitar or line-level signals?
Yes, both. Although, it is up to you to adjust levels accordingly when using guitar pedals and other gear together.
Are the channel jacks on the Patchulator 8000 normalled, half-normalled or open?
They are "open", meaning that a patch cable must always be used to pass any signal at all. This is useful in that you may not want to send an effect to itself, which may cause runaway feedback within certain devices.
Can I use flat "pancake" style 1/4-inch plugs with the Patchulator 8000?
We have not tested the fit ourselves, but have seen rigs and heard from some users that pancake jacks can be used with the Patchulator 8000. It is a tight fit.
Will I need extra cables when connecting the Patchulator 8000 to my pedalboard?
Typically, yes. When using any patchbay, you will need both a send and return cable for each effect.
Will the Patchulator 8000 add noise to my rig?
No more than adding cables would. Channels on the patchbay are electrically isolated from one another entirely thanks to non-metallic audio jacks. Unless you run all your power cables directly across the patchbay itself, or you live directly beneath a power station, perceivable noise should not be an issue. In fact, the Patchulator 8000 should be quieter than an unbalanced rack-mounted patchbay as cable runs are typically much shorter. With some amplifiers however, you may wish to ground one of the enclosure's screws to reduce the chances of added noise from such circuitry.
