Note: The noise floor is affected by Cal Level when Noise Enable
(page 399) is active.
Tip: The UAD Studer A800 default bank offers a variety of preset Tape Type,
Tape Speed, CAL level, and EQ configurations that are commonly used for
the recording of specific genres.
IPS
(Tape Speed)
The IPS (Inches Per Second) control determines the speed of
the tape transport and the associated “head bump.”
(Head bump is bass frequency build-up that occurs with mag-
netic tape; the dominant frequencies shift according to trans-
port speed.)
15 IPS is considered the favorite for rock and acoustic music due to its low fre-
quency “head bump” (low frequency rise) and warmer sound, while 30 IPS is
the norm for classical and jazz due to its lower noise floor, greater fidelity and
flatter response. 7.5 IPS is also available for an even more colored experi-
ence, with even greater frequency shift.
Tip: Click on the “IPS” text label to stop/start the spinning reels animation.
The OFF position is a bypass control. When set to OFF, emulation processing
is disabled, the VU Meter and control LEDs are dimmed, and DSP usage is re-
duced. OFF is useful for comparing the processed settings to the original sig-
nal. OFF is identical to the Thru position in the Path Select control (page 395).
Note: DSP usage is reduced only when DSP LoadLock is disabled. If DSP
LoadLock is enabled (the default setting), activating OFF will not reduce DSP
usage.
Input Input acts as an outside gain control (like an external console
fader), and adjusts the signal level going into the tape cir-
cuitry. The available range is –12 dB to +24 dB.
