- Output impedance compensation offsets headphone frequency dips and peaks
- AC coupled output prevents DC headphone damage
- Two inputs: two sources or "tape loop"
- Headphone impedance-ranging volume control - no gain switches!
- "Always-on" for optimum sound quality
- 'Green' switchmode or linear PSU1 external power supply options
- Full size headphone jack
The Solo Studio Reference "Green" Mk.II — SRGII for short, is the result of 10 years of innovative headphone amplifier development.
Originally made for studio monitoring, the Solo SRGII still finds use in commercial editing studios where it captures edit points so elusive to other headphone amps. It was also supplied to the BBC, modified to accept PO 316 (BPO) jack plugs. It is best partnered with studio headphones.
