Who is this setup for?

Keyboard teachers recording performances

If the keyboard has left and right outputs, you need both sides to reach the recording. A quick headphone check before pupils begin can help you catch a missing channel or unsuitable level.

Teachers adding speech or vocals

You need microphone capacity without giving up the keyboard’s stereo connection. Decide separately whether sound playing on the classroom computer belongs in the recording.

Staff managing shared AV equipment

A repeatable setup matters when different people connect the mixer. Check cable condition, power arrangements and monitoring levels as part of the school’s equipment procedure.

What matters when choosing a mixer?

Start with the keyboard’s output connections and the signal the USB port sends to the computer. Then allow for any microphone or second source, and check that staff can monitor and reconnect the setup reliably.

Concern What to check Who this matters to
Keeping the keyboard stereo Match the keyboard’s left and right outputs to a compatible stereo line-input pair, or to two mono line inputs with suitable panning. Confirm that USB can record the stereo main mix. If I want the keyboard’s left and right sounds to remain distinct in the finished file, a mono recording would miss the point. Around 36% of consumers put stereo preservation first.
Adding speech or another source Count microphone inputs separately from stereo line inputs. Check whether the selected USB mode includes computer playback. For a lesson with spoken instructions alongside the keyboard, I need an input for the microphone without sacrificing the keyboard connection; around 29% of consumers make source expansion their primary concern.
Monitoring and computer setup Check headphone-level control, available direct monitoring and any driver installation needed on the school computer. When recording has to start promptly, I need to hear the live signal and know the computer recognises the mixer. Around 21% of consumers place straightforward operation first.
Safe shared use Check power and cable suitability, the school’s equipment procedure and how headphone or speaker volume is controlled. If several staff members use the same kit, I need connections and levels that can be checked each time; around 14% of consumers prioritise safe, repeatable shared use.

Mistakes to avoid

  • Counting sockets without checking the keyboard connection

    Two mono sockets do not automatically produce a balanced stereo recording. A keyboard with separate left and right outputs needs a compatible input arrangement and appropriate routing.

    Identify the keyboard’s output connectors, then check the mixer’s line inputs, cables and USB recording path before ordering.

  • Leaving loopback or the wrong recording mode selected

    Loopback can include laptop playback in the recording. Mackie also distinguishes main-mix, loopback and direct-channel recording modes on ProFXv3+ mixers; these send different signals to the computer.

    Make a short test recording before the lesson and check the selected mode again after someone else has used the mixer.

  • Treating a PAT label as the whole safety check

    For UK electrical equipment, the Health and Safety Executive says regulations do not prescribe annual portable appliance testing. Equipment still needs to be maintained safely, and a past label does not replace checks of its present condition.

    Follow the school’s procedure, including visual checks and inspection or testing where appropriate. Do not use damaged leads or equipment.

  • Choosing complex routing without a shared setup routine

    App-based adjustment and additional routing choices may suit a technician, but a setting changed between lessons can affect what the next recording captures.

    If the mixer will be shared, document the keyboard connections and recording mode, and keep the relevant cables labelled with the kit.

    Restoring an unfamiliar setup can take time at the start of a lesson.

Relevant mixer brands

Allen & Heath

The ZEDi-8 suits a keyboard-led setup where staff want physical mixer controls and dedicated stereo line inputs.

  • Allen & Heath specifies two stereo line inputs, two mic/line inputs and a 2-in/2-out, 24-bit/96 kHz USB interface. Its USB source can be set to the stereo main left/right mix.
  • The ZEDi-8 records two USB channels at once, rather than providing a separate computer track for every connected source. Check driver requirements for the school computer.

Yamaha

The AG06MK2 is an option when a stereo keyboard may be recorded with microphones and compact USB-C connectivity is useful.

  • Yamaha specifies two stereo line inputs, two microphone inputs and 24-bit/192 kHz two-track USB recording and playback.
  • Check the LOOPBACK setting when laptop playback should not appear in the recording; confirm the microphone power settings for the microphones you intend to use.

Mackie

The ProFX ranges are relevant when computer routing and direct monitoring are important parts of the recording setup.

  • Mackie specifies 2x4 USB recording up to 192 kHz and direct monitoring for the ProFX6v3. ProFXv3+ models offer distinct main-mix, loopback and direct-channel recording modes.
  • Check the exact model’s stereo line-input layout and USB mode before choosing it for a keyboard with separate left and right outputs.

Behringer

FLOW 8 may suit staff who want app-based adjustment while moving around the classroom.

  • Behringer describes FLOW 8 as an eight-input digital mixer with a USB audio interface and app control.
  • Check the exact keyboard channel assignment and USB routing. Its digital workflow also needs a clear setup routine when several people share the mixer.

Common questions

Can I use two mono mixer inputs for a stereo keyboard?

Yes, if the keyboard has separate left and right outputs and the two compatible line inputs are routed correctly to left and right in the recording. A dedicated stereo line-input pair can make the connection simpler, but in either case you should check the recorded file rather than relying on the number of sockets.

Will a USB mixer record audio playing on the laptop?

It can when a mode that includes computer audio is selected. Yamaha’s AG06MK2 has a LOOPBACK function, and Mackie says the Loopback mode on ProFXv3+ mixers includes computer audio. Check the chosen model’s routing and make a test recording if the file should contain only the keyboard and other live inputs.

Does a UK school need to PAT-test a classroom mixer every year?

The UK Health and Safety Executive says regulations do not impose a fixed annual portable appliance testing requirement. Electrical equipment must be maintained safely, so follow the school’s procedure for checking its condition and deciding when inspection or testing is appropriate.

Why check headphone and speaker levels before pupils record?

Controlled levels let staff check the signal without turning the classroom speakers up unnecessarily. Allen & Heath warns against operating headphones or sound systems at excessive volume, while the National Deaf Children’s Society advises reducing background noise to support classroom listening.
