- Bring deep, lost bass back to life — the PB-DBR1 digitally restores low-frequency detail that gets stripped out when tracks are compressed for the car or Bluetooth.

- Total control from your dashboard with the included wired remote level knob.
- Tune it to your system with user-adjustable centre frequency and restoration width.

- Set up properly, sounds properly — Safe and Sound’s installers bring 30+ years of in-car audio expertise to every fitting.
Rediscover the bass you’ve been missing with the PB-DBR1 Digital Bass Restoration Processor from Safe and Sound. Every great recording sounds huge in the studio, but when it’s compressed for the car or streamed over Bluetooth, much of that low-end energy is lost. The PB-DBR1 puts you back in control — digitally rebuilding those missing low frequencies so your music feels deep, full and alive.
What the PB-DBR1 bass restoration processor does
Modern audio sources filter out a surprising amount of low-frequency information. The PB-DBR1 intelligently expands the signal’s frequency range, then hands you the controls to decide exactly how much restoration you want. The result is heart-pounding bass and smooth low-end vibration — that fuller, live-concert feel, right there in your car.
Made for every system
Ideal for compact subwoofers but equally happy on any size sub and enclosure type, the PB-DBR1 makes door speakers and smaller boxes come alive without overworking them.
- Wired dash-mount remote knob — dial your bass in from the driver’s seat.
- User-adjustable centre frequency (Sweep) from 30Hz to 80Hz, so you target the exact range you want.
- Adjustable restoration width to fine-tune how broad the effect feels.
- Selectable output voltage and ground isolation to match your amplifier and beat alternator whine.
- Fixed 30Hz subsonic filter (12dB/octave) to protect your subwoofers from damaging sub-bass.
