Strong match

Who this is for

  • Recording a vocal and an instrument at the same time
  • Stereo piano recording
  • Using vintage or modern microphones with selectable input impedance
  • Sessions that need front-panel instrument inputs, rear-panel line inputs, or an insert point

Consider the trade-offs

When to look elsewhere

  • Recording setups that need more than two microphone preamps
  • Users who do not need microphone, line, or instrument input options
