DD Audio BSI-1

Highlights 2-channel bass signal controller with integrated parametric equalizer — add punch to any system Active line converter: accepts a speaker signal from 0.5 to 40V, outputs up to 10V RCA Adjustable 24 dB/oct low-pass filter (50–500 Hz) + 24 dB/oct subsonic filter (15–50 Hz) Multifunctional remote control included: level, effect intensity, and ON/OFF Automatic speaker signal detection + REM output for amp wake-up Integrated clip indicator to detect distortion in real-time DescriptionThe 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 Technical Specifications Reference BSI-1 EAN 0850013938377 Input / Output Channels 2 / 2 Operating Voltage 10–16 V High-Level Input Impedance 180 Ω High-Level Input Sensitivity 2–20V / 4–40V RCA Input Impedance 20 kΩ RCA Input Sensitivity 0.5–5V / 1–10V Max RCA Output Voltage 10 V S/N High-Level Input 106 dBA THD 0.05 % Frequency Response 15–20,000 Hz Low-Pass Filter 50–500 Hz, 24 dB/oct (bypassable) Subsonic Filter 15–50 Hz, 24 dB/oct ParaEQ Center Frequency 30–80 Hz ParaEQ Max Boost 0–18 dB REM Output 12V / 500 mA Turn-on Threshold 10V (REM) / 1.3V (SPK/DC) / 15 mV (RCA) Dimensions 155 x 87.4 x 27 mm Why choose it? Integrated active line converter: connect directly to the factory car radio, even without RCA output Adjustable ParaEQ: add punch and depth to bass in a precise frequency range (30–80 Hz) 10V output: significantly increase the signal level to your amplifier for maximum performance Multifunctional remote control: level control + effect ON/OFF from the cabin, without touching the amplifier Clip indicator: avoid distortion and protect your speakers in real-time Compact (155 x 87 x 27 mm): integrates discreetly into any installation Available at Sound Auto Concept, your car audio specialist.
