5. 제어 및 연결
5.1 전면 패널
The front panel provides access to all user-adjustable settings:
- 하위 레벨: Rotary knob to adjust the output level of the subwoofer signal. Range from 0 to 10.
- 스테레오/모노: Push-button switch to select between stereo (out) and mono (in) operation for the subwoofer output.
- 빈도: Rotary knob to set the crossover frequency, ranging from 36Hz to 200Hz. This determines the upper frequency limit for the subwoofer output.
- 위상(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.
- 전원 LED: 장치의 전원을 켜면 녹색으로 켜집니다.
5.2 후면 패널
The rear panel houses all audio input and output connections, along with the power input:
- 입력(좌/우 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 amp전원 공급기 또는 전원 스피커.
- SUB OUTPUT (L/R RCA): Stereo RCA outputs for the low-pass filtered signal. Connect these to your powered subwoofer(s) or a subwoofer amp리퍼.
- 힘: Input jack for connecting the included 12V auxiliary power supply.
6. 설치 및 설정
Follow these steps to integrate the SX95 into your audio system:
- 연결하기 전에 모든 오디오 장비의 전원이 꺼져 있는지 확인하십시오.
- 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.
- 연결하다 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.
- 연결하다 SUB OUTPUT (L/R RCA) jacks of the SX95 to the line-level inputs of your powered subwoofer(s) or subwoofer amp리퍼.
- Connect the included 12V auxiliary power supply to the 힘 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. 운영
Once installed, adjust the controls on the front panel to optimize your subwoofer's performance:
- 하위 레벨: 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.
- 빈도: 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.
- 스테레오/모노: 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.
- 위상(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. 유지관리
The ROLLS SX95 requires minimal maintenance. To ensure longevity and optimal performance:
- 부드럽고 마른 천으로 기기를 닦아 깨끗하게 유지하세요.
- 강한 화학물질이나 연마성 세척제의 사용은 피하세요.
- 과열을 방지하기 위해 장치 주변에 적절한 환기를 확보하세요.
- Do not expose the unit to extreme temperatures or humidity.
