Subwoofer HPF/LPF
Options: ON or OFF
Range: 20 – 200Hz
The subwoofer high-pass/low-pass filter (HPF/LPF) parameters enable basic
bass-management by filtering the input signal. The Enable parameter
determines whether this bass-management filter is active or not.
For the PMC6, PMC6-2 and PMC8-2 this setting applies a 12dB/Oct high-
pass filter (HPF).
For the PMC8-SUB and PMC8-2-SUB this setting applies a 12dB/Oct low-pass
filter (LPF). However, If the XBD Mode is set to ON the filter is converted to a
12dB/Oct high-pass filter (HPF).
Delay
Options: Range: 0.00 to 30.00ms, in 0.05ms increments
This setting applies a delay to the acoustic output of the speaker. If speakers
cannot be positioned equidistant from the listening position, a delay can be
applied to the closer ones to compensate for the difference in arrival time
of the sound from each loudspeaker.
The delay control can also be used to aid integration of standalone
subwoofers.
Phase
Options: Normal or Inverted
This parameter inverts the polarity of the acoustic output of the speaker. It
can be used to aid integration of standalone subwoofers.
LF & HF Shelves
Options: ON or OFF
Gain Range: ±10dB in 0.1dB steps
Frequency Range: 20 – 20,000Hz
The LF & HF shelving equalisers can be used to adjust the tonal balance of
the speaker to suit the user's preference, or to help tune the speaker to a
particular room's acoustics.
The HF and LF shelving filters have fixed 12dB/Oct slopes with a Q of 0.707.
Parametric EQ 1 – 5
Options: ON or OFF
Gain Range: ±10dB in 0.1dB steps
Freq. Range: 20 – 20,000Hz
Q-Factor Range: 0.05 – 10.00 in 0.05 steps.
