This stereo preamp is designed to be the make up gain for the Roll Music Folcrum Passive Summing mixer. Itakes up one space in a 500 series rack.

“Give me a LEVR strong enough and I’ll move the world.” is the saying. Well, close enough.

The JCF Audio – LEVR is an active summing module for the popular 500 Series format and by drawing from the discrete playbook it expands greatly on the language audio summing.

The LEVR offers an affordable, active, non-exclusive alternative to passive summing users which other solutions do not.

Due to it’s elegant design and low parts count, the LEVR will bring unparalleled musicality and resolution to your bus.

There is an option for transformers installed on this unit which adds $100- to cost.
