Smear
This parameter controls the amount of “smear,” or signal degradation and frequency
loss. Particularly evident in the Tape Delay, the higher the setting, the more each
delay repeat loses intelligibility compared to the original signal.
Tap 1 & 2
The Tap parameters provide independent control to the two delay taps in the 2-Tap
Delay. Each tap can be set to a percentage of the delay tempo, creating interesting
rhythmic delay lines not available in the other delays.
Level 1 & 2
Adjusts the output level of Tap 1 and Tap 2.
Pan 1 & 2
Adjusts the pan position in the stereo field of Tap 1 and Tap 2.
Mod Depth
This controls the intensity of modulation, or “depth” in the Modulated Delay.
Lower settings produce a more subtle chorus effect, while higher values give a more
lush chorusing of the delay repeats.

DYNAMICS
The MX400 offers two dynamics processing modules, De Esser and Compressor, that
utilize dbx’s legendary digital dynamics processing technology to produce professional-
quality reverbs and effects.
De-Esser - Stereo
A De-Esser is a type of compressor used to tame excessive sibilance, or the “s”
sounds in a vocal performance. Note that the De-esser does not pass dry audio.
Compressor - Stereo
A compressor is used to control the dynamic range of a signal. Typically used to tighten
bass or drum tracks, or to control a vocal passage, a compressor is a very useful but
often misunderstood tool. To better use the Compressor in the MX400, a bit of
understanding about compression is helpful. Note that the Compressor does not pass
dry audio.
When a signal level crosses the Threshold level, the compressor then reduces the
amount of output level by an amount determined by the Ratio. For example, if the
threshold is set to –12dB, and the ratio set to 4:1, then when signal exceeds –12dB, the
signal level above that amount only increases by 1dB to every 4dB of signal level above
–12dB. In this case, an incoming signal of –4dB (which is 8dB above the threshold)
would result in an output signal of –10dB, or 2dB higher than the threshold level,
since the 4:1 compression ratio only allowed 2dB more output, based on the 8dB
increase above the –12dB threshold.
