Section 27
Peak Limiter
This section provides for adjusting the peak limiting parameters of the woofer, and is used to control
the short-term power to the woofer, so it will not be overdriven at high levels. It has an abrupt
engagement threshold, no knee, controlled only by the attack and release parameters.
Parameters
Thr
(Threshold), sets the threshold of the limiter action, with a range from 0 dBFS to -30 dBFS.
Factory Setting is -2.6 dBFS.
Release
, sets the release time after limiting has engaged, till the limiting is no longer engaged.
Ranges from 100 milliseconds to 5,000 ms. Factory Setting is 200 ms.
Attack
, sets how quickly the limiting engages once the threshold point has been passed.
Ranges from 1 millisecond to 1,000 ms. Factory Setting is 20 ms.
There is a
Bypass
checkbox for overall bypass of the entire Peak Limiting section at once, which
toggles the peak limiting on and off. This is located at the top right-hand side of this section.

Section 28
Hard Lim
This is a peak limiter that absolute limits the signal to the level selected, with zero time constants. No
attack, no release times.
It’s sole purpose it to prevent and avoid PWM amplifier clipping. It has been found that PWM
amplifier clipping is much more distressing and audible than a clean clip or limit in the digital domain
as implemented in this section.
The proper use of this hard limiter can allow the system to play louder with less apparent distortion
than if the PWM amplifier were allowed to clip uncontrolled, effectively extending the apparent
loudness of this portion of the system by approximately 3 dB or more.
The previous compression and peak limiting stages take care of the music dynamics with minimal
effect on the sound, and this stage minimizes the audible negative impact when the system is driven
beyond full peak output power.
Parameter
Threshold, range of 0 dBFS to -9 dBFS. Factory Setting is -2.5
Indicator
Has a Limit indicator icon to show when Hard Limiting is occurring, located at the top of this sections
strip.

Section 29
Makeup
(Make up gain),
Range is 0 dB to +9 dB.
It is recommended that this control be left at 0 dB, as adding gain at this point will defeat the correct
action of the Hard Limiter as Factory set.
If the Compressors and Limiters are re-configured away from Factory settings (which will void the
Warranty), then this control may be of some utility.
Section 30
Delay
, sets the delay time of the Output Page signal for the woofer.
Delay Units
, Radio Buttons select the units, either
ms
(milliseconds) or
meters.
