Mixer audio

USB does not automatically mean multitrack recording

A mixer may have a USB port yet send only a stereo mix to the computer. If the goal is to record a band into a DAW, verify how many USB channels are available simultaneously and where those channels are tapped in the signal path.

A conventional analogue mixer can still be part of a recording rig through direct outputs, subgroups or inserts feeding an audio interface. Digital mixers often integrate conversion and computer routing inside the console.

Channel count is only the beginning

Count the mic and line inputs you actually need, then look at aux sends, groups, matrices, inserts and direct outputs. Pre-fader sends are useful for independent cue mixes; post-fader sends follow channel level and suit different routing jobs.

If the rig uses hardware compressors and limiters or equalizers, understand the insert and send/return points. A patchbay becomes increasingly valuable as analogue connections multiply.

Analogue, digital or hybrid

Analogue desks offer immediate physical signal flow. Digital mixers add scenes, onboard processing, deeper routing and often remote control. Choose by workflow: musician count, cue mixes, session recall, outboard integration and simultaneous recording requirements.

Test more than one channel on a used mixer

Feed the same source into different channels and compare gain, phantom, EQ, faders, pan, aux and buses. Test every output and the headphone section. Digital desks add screens, encoders, networking, firmware and control-app support; USB mixers add driver compatibility.
