My Mixer

During 2015 my hardware synth collection grew considerably while the audio interface still had limited input connections. This led to an investment not of a bigger audio interface, but of an analog mixer.

By then I was looking for a no-frills compact mixer that was able to make a clear, pristine mix with high headroom and low noise. I had no need for neither built-in effects nor USB connection, but wanted a small footprint mixer and great sound quality. So I got the Mackie 1202VLZ4.

Even if I’m using the mixer merely as a patch bay, more or less a set and forget scenario, it’s a quite creative mixer. For example, the mute/alt 3–4 function serves both as muting and signal routing (where it acts as an extra stereo bus). This means that the alt bus can be used to route shit through serial effects as a stereo channel, which in turn opens up for further possibilities.

The 1202VLZ4 also has channel insert, and I’m now thinking of getting some effects, perhaps something from Strymon or Eventide.

In brief, I’m happy with the mixer, but I honestly haven’t had that many analog mixers, so I can’t really compare this one to others. Some say the 1202VLZ4 offers bang for the buck featuring Mackie’s flagship Onyx mic preamps and so on, but I, for one, can only say it works well.

P.S. There are times when I would have preferred an audio interface with like 18 input connections that could be mixed and recorded on separate tracks inside the DAW, true. But most of the time I only need the 4 voices of the Analog Four to be recorded individually, and with Overbridge it is possible already.

Recording Levels

Gain staging refers to the process of managing the relative levels – at each stage of the audio signal path – in the mix to prevent introduction of noise and distortion. This can have a profound impact on the quality of your recordings.

Generally, the goal is to keep the signal chain as clean as possible, that is, high above the noise floor without overloading. Proper gain staging is critical in setting the levels to maximize the signal-to-noise ratio of the input signals.

Treat every device in the setup as an opportunity to compound errors. Consider both hardware and software components of this issue (although headroom is not really a problem in the digital world).

So don’t run hot during mixing or the D/A converters will start to introduce clipping and artefacts. Still, you can clip shit, e.g. the drum channel (by doing so you can achieve some effect, some pop). That being said, never let the master fader clip.
