Frequently Asked Questions - Buff Mult 4ms
What is the 4ms Buff Mult?
The 4ms Buff Mult is a buffered multiple Eurorack module that takes one input and provides four identical buffered outputs, ensuring no signal degradation when splitting audio or CV signals.
Does the Buff Mult require power?
Yes, the Buff Mult is active and requires +12V and -12V power from your Eurorack case to operate the buffer circuitry.
What is the width of the Buff Mult?
The module is 2HP wide, making it very compact and suitable for tight cases.
Can I use the Buff Mult with audio and CV signals?
Yes, it works with both audio and control voltage (CV) signals, as long as the levels stay within Eurorack standards (typically ±10V).
How do I connect the power cable?
Connect a standard 10-pin Eurorack ribbon cable with the red stripe indicating -12V. Align the red stripe with the -12V marking on the module.
Why is my signal still weak after using the Buff Mult?
Ensure the module is properly powered and that all patch cables are fully inserted. If the input signal is already weak, the buffered copies will also be weak.
Can I daisy chain multiple Buff Mults?
Yes, you can connect the output of one Buff Mult to the input of another to create more copies, but each buffered output can drive multiple loads without issue.
Is the Buff Mult compatible with semi-modular synthesizers?
It can be used with semi-modular gear if the signal levels and connectors are compatible (3.5mm TS jacks, Eurorack levels).
How do I clean the Buff Mult?
Use a dry, lint-free cloth to gently wipe the front panel. Avoid any liquids or sprays.
What is the warranty on the Buff Mult?
4ms offers a 1-year warranty against manufacturing defects. Consult the user manual for details.
