- Мастер јачина звука: Adjusts the overall output level of the equalizer.
- Изаберите улаз: Switches between CD (Low-Level RCA/High-Level) and AUX inputs.
- Fader (F/R): Balances the audio output between front and rear channels.
- Level (Digital Bass Processor): Adjusts the intensity of the digital bass reconstruction.
- Subsonic (35Hz/80Hz): Selects the cutoff frequency for the subsonic filter.
- EQ Bands (50Hz, 200Hz, 1kHz, 5kHz, 20kHz): Adjusts the gain (±18dB) for each frequency band.

Решавање проблема
| Проблем | Могући узрок | Решење |
|---|---|---|
| Нема струје | Blown fuse, incorrect wiring, loose power connection. | Check inline fuse, verify +12V, GND, and REM connections. Ensure connections are secure. |
| Нема аудио излаза | Incorrect input selection, loose RCA connections, ampУређај за спасавање није напајан. | Verify Input Select switch position. Check all RCA connections. Ensure ampСпасиоци су укључени. |
| Изобличен звук | 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). |
| Слаб бас | 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. |
