SPECIFICATIONS
NOTE: All specifications are typical unless
otherwise noted.
0 dBV = 1 volt RMS
0 dBu = .778 volts RMS
All specs are referenced to nominal output
level (0 dBV) unless otherwise noted.
All measurements are wideband 20 Hz to 20
kHz unless otherwise stated.
All control settings are nominal (50%
rotation) unless otherwise noted.
