LIMITER 5-BAND PAGE
Link Limiter
Range: On/Off
When Link is active, the same amount of peak
limiting is always applied to both channels.
Some broadcasters like the sound of operating
left and right limiting without stereo coupling
because they feel that it maximizes loudness
and widens the stereo image. On dual mono
sources, of course you should always choose
un-linked Limiter operation.
The Configuration control on the Main
page does not affect the Link Limiter
setting. This link is running individually
from the selected configuration.
Softclip A/L and B/R
Parameter range: - 3dB to Off
When active, Soft Clip applies a saturation
effect on signals close to maximum Output
level. The threshold is relative to the Threshold
of the Brickwall Limiter.
This controlled distortion of transients works
well for adding loudness, but is not a desirable
effect with some data compression codecs.
While the Brickwall Limiter is extremely low
distortion, Soft Clip is not. Use your own
judgement if you want it or not.
Threshold A/L & Threshold B/R
Parameter range: -12 to 0.0dBFS
Sets the Threshold of the Brickwall Limiter.
The Threshold is relative to 0 dBFS, not to the
Reference Level set on the Main page.
The Brickwall Limiter uses 48 bit processing
with distortion figures surpassing the quality
demands of DVD-Audio mastering.
Oversampling is used to prevent intersample
32 33
Try setting the Steer and/or Threshold
parameters differently in the bands to hear the
effect. High Steer values add more detail gain
than low values, but remember that Threshold
has to be negative to add detail gain at all.
DXP Threshold relates to the Reference Level
set on the Main page.
To disable DXP detail gain at very low
levels, use the Defeat Threshold and
Defeat Ratio controls. Defeat threshold
relates to the DXP threshold, and allows for a
certain level-window, inside which detail gain is
applied. Defeat Ratio determines the slope at
which DXP detail gain is defeated.
Ratio - DXP mode OFF
Parameter range: Off to Infinity:1
Press this button to access the five individual
band Ratios and the overall All Ratio.
The parameters are Automatically assigned to
fader 1-6.
Attack
Parameter range: 0.3 to 250ms
Press this button to access the five individual
band Attacks and the overall All Attack.
The parameters are automatically assigned to
fader 1-6.
Release
Parameter range: 20ms to 7s
Press this button to access the five individual
band Release and the overall All Release.
The parameters are automatically assigned to
fader 1-6.

Reset menu
& software load
To enter the following functions hold
WIZARD key while powering up the unit.
Once entered this menu navigation is as
follows:
• Press PRESET keys 4 and 8 to scroll in
menu.
• Press LOCK to confirm/enter
• Press BYPASS to cancel
“L” - Load
Indicates Load mode and is used when loading
application software.
Press LOCK (enter) to load the information
present in the inserted PCMCIA card.
“R” - Reset
Press LOCK (enter) to reset the unit.
When LOCK is pressed once the “R” in the
display will start to flash and the unit is ready to
be reset.
You can now abort/cancel the operation by
pressing the BYPASS key or press LOCK a
second time to actually reset the unit.
While resetting a “+” is displayed.
“A” - Boot software version
Press LOCK (enter) to see current loaded boot
software version.
For service-purposes only.
“V” - Operating software number
Press LOCK (enter) to see current loaded P2
software version.
“N” - Serial Number
Press LOCK (enter)to see serial number for
this unit.
“S” - Start
Reboots the P2 for normal use.
When rebooted after a Reset procedure has
taken place all Front Presets are reconfigured.
The reconfiguration process takes approx. 15
seconds during which the eight PRESET key
LEDs will flash. Be patient.
peaks from reaching the Output, and time-
constants adapt to the Input signal.
Fader A & Fader B
Parameter range: Off to 0dB
Fader function on the Output. When Dual Mono
configuration is selected, individual Output
faders are available.
