Konec izdelkaview
The Soundstream MPQ-6BX is a compact 1/2 DIN 5-band equalizer designed to enhance your car audio system. It features digital bass reconstruction, a selectable subsonic filter, and flexible input/output options for comprehensive sound control.
Ključne značilnosti:
- 5-Band Equalization: Provides ±18 dB adjustment at 50 Hz, 200 Hz, 1 kHz, 5 kHz, and 20 kHz for precise frequency tuning.
- Digital Bass Reconstruction: Restores low frequencies often lost during audio compression, enhancing bass impact.
- Podzvočni filter: Selectable 35–80Hz filter protects subwoofers from unwanted ultra-low frequencies.
- Vsestranski vložki: Includes AUX, low-level RCA, and high-level speaker inputs for compatibility with various head units.
- High Output Preampdvigalo: Delivers 7V RMS / 12V peak preamplifier outputs with ultra-low 0.01% Total Harmonic Distortion (THD) and a 110 dB Signal-to-Noise Ratio (SNR).
- Kompaktna zasnova: 1/2 DIN size (7" W x 5.1" D x 1.2" H) for easy installation in tight spaces.

- Input Level (90Hz/150Hz/200Hz): Adjusts the input sensitivity for the digital bass processor. Experiment to find the best setting for your source.
- Ground Isolation (200Ω/GND/ISO): Helps eliminate ground loop noise. Try different settings if you experience hum or hiss.
- Izhodna voltage (5V/7.5V/10V): Sets the maximum output voltage od predamplifier. Match this to the input sensitivity of your amposvežilci.
Vzdrževanje
The Soundstream MPQ-6BX is designed for reliable operation with minimal maintenance.
- Čiščenje: Za čiščenje enote uporabite mehko, suho krpo. Ne uporabljajte abrazivnih čistil ali topil.
- Povezave: Občasno preverite vse ožičene povezave, da se prepričate, da so varne in brez korozije.
- Okolje: Ensure the unit remains in a well-ventilated area, free from excessive heat, dust, and moisture.
Odpravljanje težav
| Težava | Možen vzrok | rešitev |
|---|---|---|
| Brez moči | Blown fuse, incorrect wiring, loose power connection. | Check inline fuse, verify +12V, GND, and REM connections. Ensure connections are secure. |
| Ni zvočnega izhoda | Napačna izbira vhoda, ohlapne RCA povezave, amplifier not powered. | Verify Input Select switch position. Check all RCA connections. Ensure amplifiers are powered on. |
| Popačen zvok | Input level too high, output voltage mismatch, EQ settings too extreme. | Reduce head unit volume. Adjust Input Level and Output Voltage switches. Reset EQ bands to flat and adjust gradually. |
| Engine noise/hum | Ground loop, poor ground connection. | Ensure a clean, secure ground connection. Experiment with the Ground Isolation switch (200Ω/GND/ISO). |
| Šibek bas | Digital Bass Processor level too low, Subsonic filter set too high, EQ bass band reduced. | Increase Digital Bass Processor Level. Adjust Subsonic filter to a lower frequency or off. Increase 50Hz EQ band. |
