Product Usage Instructions:

Power Connection:

1. Turn off the power supply or rack case.
2. Insert the 16-pin connector on the power cable into the socket on the power supply or rack case.
3. If needed, align pin 1 with the red stripe on the cable.
4. Insert the 10-pin connector into the socket on the back of the module.
5. Securely attach both ends of the power cable.
6. Mount the module in a case and turn on the power supply.

Installation:

1. Connect the power cable before mounting the module.
2. Align the mounting holes of the module with the threaded rails or plates of the Eurorack case.
3. Attach screws partially to allow for adjustments in positioning.
4. Once positioned correctly, tighten all screws securely.

FAQ:

Q: What should I do if I encounter VCF oscillation during usage?

A: Check the CUTOFF FREQ slider as it may be causing the oscillation. Adjust the slider to potentially resolve the issue.

Q: How do I control the pulse width manually?

A: Use the MOD MANUAL control to adjust the pulse width manually. When a jack is inserted, this control acts as a MOD input level control.

Q: What should be done if the power supply does not have a keyed socket?

A: Ensure that pin 1 (-12 V) is oriented with the red stripe on the cable before inserting it into a non-keyed socket to prevent incorrect insertion.

Installation
The necessary screws are included with the module for mounting in a Eurorack case. Connect the power cable before mounting.
Depending on the rack case, there may be a series of fixed holes spaced 2 HP apart along the length of the case, or a track that allows individual threaded plates to slide along the length of the case. The free-moving threaded plates allow precise positioning of the module, but each plate should be positioned in the approximate relation to the mounting holes in your module before attaching the screws.
Hold the module against the Eurorack rails so that each of the mounting holes are aligned with a threaded rail or threaded plate. Attach the screws part way to start, which will allow small adjustments to the positioning while you get them all aligned. After the final position has been established, tighten the screws down.
