Strong match

Who this is for

  • Recording engineers seeking the stated ISA 110 preamp circuit and Lundahl input transformer
  • Vocal and instrument recording where a front-panel DI feed is useful
  • Users who want four input-impedance settings for tone shaping
  • Mobile studio or live-vocal use requiring an all-metal enclosure

Consider the trade-offs

When to look elsewhere

  • Anyone needing more than one preamp channel
  • Buyers who require A/D conversion as a standard included feature
  • Users who do not need microphone preamplification or a DI input
