Nord Mixer

Netjes/nice!

Just to share. I was using a Rolls PM351. Works great for my purpose, but needed extra functionality and used the mic input to hear my click send, and that was noisy because it is not designed for a line-level input.

My input needs:
- Stereo Keys 1 (Nord Stage 3)
- Stereo Keys 2 (Nord Wave 2)
- Mono Backing Track (from iPad left)
- Mono Click Track (from iPad Right)
- Stereo Aux mix from Main Desk with my own mix from rest of the band

Output:
- Stereo output to Main desk (Containing mix of keys + Backing track)
- mono Click to Main desk (contraining click only)
- Headphone (Mix of keys, aux-mix, click track)

I found this cheap mixer from Aliexpress:


With two of those I could make everything as i want it and put everything in a case with exact the wiring I want inside. Painted it Nord-red.
Nice Corona project....
Works great!

I've added an extra input.

The top 4 knobs control the main output mix:
- External input
- Backing track volume
- keys1 volume
- keys 2 volume

The bottom 4 knobs control the headphone mix:
- Main output mix (Keys)
- Mix from Aux
- Click track level

if you ever want to make another i would buy from you in a heartbeat . brilliant idea

Is is very simple to build one:
buy one or two of those mixers, buy a fitting box and connectors, drill some holes.
Spraypaint with a can and assemble.
Any configuration is possible that suits you.

I removed the connectors from the chinese mixers and soldered the wires directly on them to make sure there is a very good connection.
For most interconnections I used shielded wire and tried to connect all grounds to one point (star-ground)

Tried several adapters, some gave a buzz but i found 2 working.
They say 5V will work, with i found out that that reduces the headroom of the levels and I got distortion.
Now I use a 12V adapter. Absolutely noise-free and it even drives my AKG-K240 headphone that is hardly working from the NS3 output

Brilliant idea. For a next version could the the outputs be located one the side? That way one can use angled plugs. I do not know if there is enough space for that...

Yes, easier to insert when attached to the Nord!

My experience is that the the third time you get it right...

Hi Eriknie

Its a lovely thing.
Are you saying that it is an 8 input 4 output mixer.
Your input needs suggest you need 3 stereo and 2 mono input channels,
And 1 stereo and 2 mono outputs. Also is the headphone output powered.

Headphone output is powered direct from the PCB mixer. Very strong output, even drives my hard to drive AKG headphone.
I have enough inputs and outputs with 2 internal mixers.

Nope, I hardly have time to support my own hobbies...
