Lo-Fi Simulates the effect of a limited-band-
width analog tape device, such as an outboard
tape-based echo effect.
Tape Formula
The Tape Formula control lets you select either
of two magnetic tape formulations emulated by
the plug-in, each with its own saturation charac-
teristics:
Classic Emulates the characteristics of
Ampex 456, exhibiting a more pronounced satu-
ration effect.
Hi Output Emulates the characteristics of
Quantegy GP9, exhibiting a more subtle satura-
tion effect.
Reel Tape Saturation
Controls
In addition to the Drive, Output, Tape Machine,
and Tape Formula controls, Reel Tape Satura-
tion has the following controls:
Speed
The Speed control adjusts the tape speed in ips
(inches per second). Tape speed affects the fre-
quency response of the modeled tape machine.
Available tape speeds include 7.5 ips, 15 ips, and
30 ips, with a default setting of 15 ips.
Noise
Reel Tape Saturation produces noise only dur-
ing playback and recording, and not when the
transport is stopped.
The Noise control adjusts the level of simulated
tape noise that is added to the processed signal.
The characteristics of the noise depend on the
Speed, Bias, and Tape Machine settings, and the
relative level of the noise depends on the Drive,
Cal Adjust, and Tape Formula settings.
Noise is adjustable from Off (–INF) to –24 dB,
with the default value being Off.
Bias
The Bias control simulates the effect of under-
or over-biasing the modeled tape machine. Bias
is adjustable from –6 dB to +6 dB, with a default
value of 0.0 dB. The 0.0 dB value represents a
standard overbias calibration of 3 dB for analog
tape machines, so the control acts as a bias offset
rather than as an absolute bias control.
Cal Adjust
Cal Adjust simulates the effect of three common
calibration levels on the modeled tape machine
and magnetic tape formulations.
With the evolution of tape formulations, it was
possible to increase the fluxivity level, or mag-
netic strength, of the signals on tape. Over the
years, this resulted in an elevation of recorded
levels relative to a standard reference fluxivity
(185 nW/m at 700 Hz). The Cal Adjust value ex-
presses the elevated level in dB over this stan-
dard reference level.
The Cal Adjust control does not affect the over-
all gain, but does affect the amount of saturation
effect for a given input signal.
Available Cal Adjust values are:
• +3 dB (equivalent to 250 nW/m)
• +6 dB (equivalent to 370 nW/m)
• +9 dB (equivalent to 520 nW/m)
The default value is +6 dB.
