Quantus Ampla demo - 4-channel VCA and VCA: voltage-controlled amplifier & attenuator

The Quantus Ampla from Noise Engineering is a 6HP Eurorack modular that's a voltage-controlled amplifier and a voltage-controlled attenuator. It has four channels of linear DC-coupled goodness for all your VCA needs: ducking, mixing, CV-controlled leveling, and more!

The QA is not just any VCA: with some unique normalling, mixing, and CV options, you can use it for a plethora of tasks. Each channel has two modes: Amplify, which gives you normal VCA response, and Attenuate, which makes the VCAs close instead of open in response to positive CV. The CV inputs are circularly normalled, so you can easily create ducking effects over multiple voices, volume fades, and transitions, all with minimal patching. Plus, the outputs mix down, so it can be two two-channel mixers, a 3 channel mixer, a 4 channel mixer... Oh, and did we mention that it can process CV signals, too? The possibilities are endless.

The reverse effect using the slow attack envelope is an amazing feature of this VCA. It looks so simple but it’s a great feature without having to use a separate signal inverter. Demo sounds amazing.

Damn it! POB’s jams are so rad in these demos. 🔥🔥🔥

I really like these videos a lot more than the older ones with no talking. I prefer hearing the explanation rather than reading. You should maybe redo some of those older in the new format.

Thank you for the patch book, that's very helpful for me to understand how the module can be used.

Time to start uploading these demo tracks to Bandcamp Fridays

I love you Noise Engineering. You are the thoughtful dominatrix that keeps me happy

[Misksound]

this is great module design. so simple but i've been patching something like this together from scratch waaaay too often

[ishykashy]

This is going to be a game changer for me. Can't wait for it to arrive. Great work!

[oscidigi]

Find the individual who thumbs downed this and punish them

[Honeysmack]

Love it, clever thinking as always NE!

[SoundDevour]

sweet! Just what I was in the market for.

So.... Could you feed a stereo Mix out through this and have a mono kick controlling the ducking? I'm guessing so. I have a stereo VCA with offset but when the track is stopped the VCA opens fully which is annoying when you want to end the track.

I just ordered an envelope with inverted output capabilities and 3x scaler/offsets to deal with sidechain stuff 🤦
