FEATURES
Digital Bass Restoration:
Enhance your overall sound by restoring the missing low frequency parts that
todays sound reproduction devices tend to filter out. Smaller subwoofers and door speakers come alive again
when the PB-DBR1 is engaged.
2 Channel Preamp Input and Output Connect RCA's directly from your source unit to allow the
full signal to pass through the PB-DBR1 for processing to the output RCA connection for your
amplifier.
User Adjustable Center Frequency The Sweep adjustment allows you to set your center
frequency. This is the middle of the frequency range you want to restore, once set you will
need to adjust how wide of a range you want to be effected by the processor.
User Adjustable Frequency Range The Wide adjustment allows you to determine the width
of frequency range that will be restored by the processor. A lower adjustment will result
in a narrow range while a higher adjustment will result in a very wide frequency range.
User Selectable Output Voltage Range (2.5V-10V RMS*)
By removing the top cover you can
set the range of the output voltage from 2.5 up to 10V RMS or select a custom
configuration for a higher minimum starting point or a lower maximum setting.

other outside factors adjusting the ground isolation can help remedy this. Select between

fixed. Please be sure that the PB-DBR1 is not turned
on and the system is turned OFF before moving the jumpers.
User Selectable Balanced or Unbalanced Preamp Inputs*
Most audio systems will only require
the balanced position however in the event that your audio system is attempting to reference
ground via the RCA connection we recommend using the Unbalanced configuration. Please be
sure that the PB-DBR1 is not turned on and the system is turned OFF before moving the
jumpers.
Fixed Subsonic Filter 30Hz 12/db Octave
Subsonic filters help keep your speaker in control by
filtering extreme low frequencies that might cause damage to your speaker.
Wired Remote Level Control Take control of your sound by adjusting the output level
remotely. This can be mounted near the operator for easy adjustment from the listening area.
