5. Controale și conexiuni
5.1 Panoul frontal

The front panel provides access to all user-adjustable settings:
- NIVEL SUB: Rotary knob to adjust the output level of the subwoofer signal. Range from 0 to 10.
- STEREO/MONO: Push-button switch to select between stereo (out) and mono (in) operation for the subwoofer output.
- FRECVENŢĂ: Rotary knob to set the crossover frequency, ranging from 36Hz to 200Hz. This determines the upper frequency limit for the subwoofer output.
- FAZĂ (0°/180°): Push-button switches for LEFT and RIGHT channels to invert the phase of the subwoofer output by 180 degrees. This helps in optimizing bass response relative to your main speakers.
- LED PWR: Se aprinde în verde când unitatea este pornită.
5.2 Panoul din spate

The rear panel houses all audio input and output connections, along with the power input:
- INPUT (L/R RCA): Stereo RCA inputs for connecting the audio source (e.g., preamplifier, receiver's line output).
- PASS THRU (L/R RCA): Stereo RCA outputs that provide the full-range input signal without any processing. Connect these to your main ampamplificator sau difuzoare amplificate.
- SUB OUTPUT (L/R RCA): Stereo RCA outputs for the low-pass filtered signal. Connect these to your powered subwoofer(s) or a subwoofer ampmai în viață.
- PUTERE: Input jack for connecting the included 12V auxiliary power supply.
6. Instalare și configurare
Follow these steps to integrate the SX95 into your audio system:
- Ensure all audio equipment is powered off before making connections.
- Connect the line-level output from your audio source (e.g., preamplifier, receiver) to the INPUT (L/R RCA) jacks on the SX95 rear panel.
- Conectați PASS THRU (L/R RCA) outputs of the SX95 to the inputs of your main amplifier or powered speakers. This will carry the full-range signal to your main audio system.
- Conectați SUB OUTPUT (L/R RCA) jacks of the SX95 to the line-level inputs of your powered subwoofer(s) or subwoofer ampmai în viață.
- Connect the included 12V auxiliary power supply to the PUTERE input on the SX95 rear panel, then plug the power supply into an AC outlet. The PWR LED on the front panel should illuminate.
- Power on your audio source, main amplifier/speakers, and subwoofer(s).
7. Funcționare
Once installed, adjust the controls on the front panel to optimize your subwoofer's performance:
- NIVEL SUB: Start with the SUB LEVEL knob at a low setting (e.g., 3-4). Play some audio and gradually increase the level until the subwoofer blends seamlessly with your main speakers without overpowering them.
- FRECVENŢĂ: Adjust the FREQUENCY knob to set the crossover point. This should typically be set based on the frequency response of your main speakers and subwoofer. A common starting point is 80Hz, but experimentation is recommended to find the ideal blend for your specific setup and room acoustics.
- STEREO/MONO: If you are using a single subwoofer, press the STEREO/MONO button in for mono operation. If you are using two subwoofers and wish to maintain stereo separation for the low frequencies, leave the button out for stereo operation.
- FAZĂ (0°/180°): The phase switches help align the subwoofer's output with your main speakers. Listen to music with strong bass and try both 0° and 180° settings for each channel. Choose the setting that provides the most impactful and coherent bass response. Often, the correct phase will result in a fuller, more defined bass sound.
8. Întreținere
The ROLLS SX95 requires minimal maintenance. To ensure longevity and optimal performance:
- Păstrați unitatea curată ștergându-l cu o cârpă moale și uscată.
- Evitați utilizarea substanțelor chimice dure sau a agenților de curățare abrazivi.
- Asigurați o ventilație adecvată în jurul unității pentru a preveni supraîncălzirea.

9. Depanare
| Problemă | Cauza posibila | Soluţie |
|---|---|---|
| No power (PWR LED off) | Power supply not connected or faulty; AC outlet not active. | Check power supply connection to unit and outlet. Test outlet with another device. |
| No subwoofer sound | Incorrect connections; SUB LEVEL too low; subwoofer powered off or faulty. | Verify all RCA connections. Increase SUB LEVEL. Ensure subwoofer is powered on and functioning. |
| Main speakers have no sound | Incorrect PASS THRU connections; main amplifier powered off or faulty. | Ensure main amplifier/speakers are connected to the SX95's PASS THRU outputs. Check main ampputerea de eliminare. |
| Bas slab sau noroios | Incorrect FREQUENCY or PHASE settings. | Adjust FREQUENCY knob to find optimal crossover point. Experiment with PHASE (0°/180°) settings for both channels. |
| Zumzet sau zgomot | Ground loop; faulty cables; interference. | Ensure all components are on the same electrical circuit. Try different RCA cables. Keep audio cables away from power cables. |
