HMX MOSFET SATURATOR:
THD+N @ 0 dBu Min. Drive (1 kHz): 0.35% (2nd & 3rd only)
THD+N @ 0 dBu Max. Drive (1 kHz): 2.73% (2nd to 4th dominate)
NOISE @ Min. Drive -73 dBu (like an old tube amp!)
FREQUENCY RESPONSE: 30 to 150Hz low frequency
emphasis bump - see below
WAVESHAPING: Asymmetrical
Tube-like soft clipping
HMX offers a valve (tube) like soft clipping that is pre and de-emphasised
with passive filtering to achieve a fat low frequency response with a softened
midrange. It uses three cascased MOSFET class-A amplifiers to reach high
levels of musical distortion, but the output level is always held constant so
your ears are not biased by loudness. Some extra noise will act as a nice
analogue dither when inside the DAW, why use a plugin to add analogue
modeled noise when you can have the real thing?!
IRON TRANSFORMER SATURATOR:
THD+N @ 0 dBu Min. Drive (1 kHz): 0.11% (2nd & 3rd mostly)
THD+N @ 0 dBu Max. Drive (1 kHz): 0.006% (cleans up as driver load
changes)
THD+N @ L.F (<300 Hz):
Complex variance with level and
frequency - distorts bass content
NOISE @ Min. Drive -84 dBu (like a 2” tape machine)
FREQUENCY RESPONSE: 4k to 15kHz rising air boost /
resonance - see below
WAVESHAPING: Symmetrical/Magnetic Loop
Transient Shaping & Phase Shift
IRON provides a complex variable effect with one simple control that
can shift phase, tighten sub frequencies, slew transients and distort
low frequencies with symmetrical magnetic core saturation. There is
also a small amount of asymmetrical saturation present in the drive
& recovery amplifiers for a very complex but subtle palette of tone!
The frequency response has an air boost present that is manipulated with
secondary loading of the 1:1 transformer to replicate the magic of the 70’s,
adding the smooth, zingy air to high frequencies that can add to perceived
depth in the top end. Combine with HMX for big tone from ASP800.
