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.

User Selectable Ground Isolation Configuration* If noise is presented by alternator wine or other outside factors adjusting the ground isolation can help remedy this. Select between reference ground, fully isolated, or 200Ω 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.

INTERNAL SETTINGS INSTRUCTIONS

NOTE: The system must be powered OFF when making changes to the internal settings.
Do not remove or insert a jumper while the system is powered ON

7. OUTPUT VOLTAGE CONTROL JUMPERS: The PB-DBR1 can either increase or decrease the output voltage of the Bass Restoration Circuit. Depending upon your system, you may change these jumpers to a higher or lower setting to maximize your output while protecting your speakers. In most systems the factory setting will be best all around.

8. GROUND ISOLATION JUMPERS: Occasionally alternator while may appear in a system because the source unit and amplifier may use a different ground reference. To help with this situation, the PB-DBR1 provides alternative grounding solutions.

9. INPUT GROUND ISOLATION JUMPERS: With most systems you can leave the jumper set in the BALANCED position. In some systems, the source unit may look for a ground through the RCA connectors. In this event, you should set the jumpers to the UNBALANCED position.
