Description

The DD Audio BSI-1 is a bass signal processor designed to extract maximum bass from any source, even the most limited factory car radios. It combines an active line converter, a parametric bass equalizer, adjustable low-pass and subsonic filters, and a multifunctional remote control in a single compact housing. Perfect for installations without a dedicated DSP, especially with high-power amplifiers (SounDigital, DD Audio, etc.) that do not have integrated level control.

• Speaker input (high level): 0.5 to 40V — compatible with all factory car radios
• RCA input: 0.5–5V / 1–10V
• Max RCA output: 10V
• Parametric equalizer: center frequency 30–80 Hz, boost 0–18 dB, adjustable bandwidth (narrow to wide)
• Low-pass filter: 50–500 Hz, 24 dB/oct (jumper-selectable bypass)
• Subsonic filter: 15–50 Hz, 24 dB/oct
• Remote control included: level adjustment, ParaEQ effect intensity, effect ON/OFF
• Automatic signal detection + 12V / 500 mA REM output
• Luminous clip indicator
