The 2-inch tape sound, with the good noise and none of the aliasing.
Spulentonband rebuilds the Studer A800 multitrack tape machine from Studer's own service manual. The record amplifier's equaliser, treble chain and limiter and the reproduce amplifier's equaliser come from the machine's circuit cards, and the low end is matched to Studer's own measurements of the A800 within half a decibel. Put it on a track, a drum bus or the whole mix, raise INPUT and watch the two backlit VU meters: past 0 VU the tape thickens, rounds off the transients and pulls everything together.
What it does
- Tape 250, 456, 900 or GP9 at 7.5, 15 or 30 IPS, NAB or CCIR, calibrated +3, +6 or +9
- Bias from Studer's own table: over-bias for classic tape compression, under-bias for grit
- HF driver, repro LF and HF trims, and an optional line transformer for low-end weight
- The good noise: tape hiss shaped by the playback EQ, modulation noise, wow and flutter, optional hum, all at real-machine levels
- Clean by design: 4x oversampling by default (up to 8x), exact anti-aliasing on the tape, the record amp limiter and the line amp
- VU meter bridge (record or repro), saturation LEDs and an LCD that reads how hard you're hitting the tape: drive re MOL, peak flux, distortion and compression
- 20 factory presets: machine line-ups, mix bus, drums, tracks and character
- Dark or light panel, resizable from 60 to 200 %
