Overview
Recording at a desk or in a project studio is where this preamp fits between a microphone or instrument and a recorder. Starting-point voicings are built in for several instruments, and an output limiter protects the next device.
The reason to buy is a tube stage with ready-made voicings that can still be tweaked. The limit is that the listing gives no gain range, no input list and no power supply detail.
Who it's for
A project studio feeding a hard-disk recorder or an audio interface from a single microphone or instrument works well. Anyone tracking a full band, or needing a complete input list, should look for a multi-channel unit.
Pros and cons
- Preset voicings for many instruments
- Presets can be adjusted
- Output limiter protects recorder
- Compact desktop size
- Single channel only
- Input types not listed
- Gain range not listed
- Listing counts five items oddly
Performance notes
The Variable Valve Voicing circuit changes how the tube stage responds so each preset gives a different starting tone. The built-in limiter holds peak level below what the next device can accept. Final results depend on the microphone, the instrument and the recorder.
