OVERVIEW
FEATURES
CONTROLS
GAIN
Controls the magnetic field strength in the Tape Element
- Adjusts the input level by ±20 dB
- Simultaneously applies ±20 dB attenuation at the output, maintaining consistent output level during adjustment
BIAS
Sets the level of the bias field in the Tape Element
- Raising bias provides less color (overbias)
- Lowering bias provides more color (underbias)
- 0 dB provides the nominal calibration (maximum sensitivity)
HF
Restores high frequencies attenuated by bias
- Provides up to 8 dB of gain at 20 kHz prior to the Tape Element
- 4 dB provides the nominal setting when bias is set for maximum sensitivity
OUT
Increases the output level
- Provides 16 dB of gain after the Tape Element
IN
- ON: Engages the full T805 circuit and Tape Element
- OFF: True analog bypass

CALIBRATIONS
NOMINAL
The Nominal calibration yields maximum bias sensitivity and a balance of color and magnetic compression. This provides a tape sound commonly heard in the 50s, 60s, and early 70s.
Digital
T805 (NOMINAL)
OVERBIAS
The Overbias preset yields lower bias sensitivity with less color and less magnetic compression. This provides a tape sound commonly heard in the 70s and later.
