LD Systems SUB 88 A - Active Subwoofer 2 x 8" User Manual

1. 서론

The LD Systems SUB88A active subwoofer features two 8" loudspeakers and delivers 600 W Peak power. The SUB88A is the active version of the SUB88, one of our most popular subwoofers. It is equipped with a 600 Watt (peak) mono amplification module that offers excellent sound and dynamic characteristics. This subwoofer is the ideal partner for our SAT62A active loudspeakers, our SAT42/242/62 passive loudspeakers in combination with an external amplifier (like DJ200), or for all types of satellites if you wish to enrich the sound with deep and powerful bass.

   • Connect the audio output from your mixer, audio interface, or pre-amplifier to the INPUT (XLR/TRS Combo Jack) on the subwoofer's rear panel using a balanced XLR or TRS cable.
   • If connecting satellite speakers, ensure they are connected to the appropriate outputs on your mixer/interface, or if your setup allows, route them through the subwoofer's high-pass outputs (if available, though not explicitly listed for this model, typical for subwoofers).

Instructions for operating your LD Systems SUB 88 A subwoofer.

1. 전원 켜기: Once all connections are made, switch the POWER button to the ON position. The POWER LED should illuminate.

3. 크로스오버 조정: 조정하다 SUB CROSSOVER knob to blend the subwoofer's output seamlessly with your main speakers. A lower setting (e.g., 80 Hz) is suitable for larger main speakers, while a higher setting (e.g., 120 Hz or more) may be needed for smaller satellite speakers. Experiment to find the best balance.
4. 위상 조정: While playing music with strong bass, toggle the 하위 단계 switch between 0° and 180°. Choose the setting that produces the most impactful and defined bass. This compensates for acoustic phase differences between the subwoofer and main speakers due to their placement.
5. 모니터링: Pay attention to the SIGNAL and LIMIT LEDs. The SIGNAL LED confirms audio input. If the LIMIT LED flashes frequently or stays lit, reduce the input signal level from your source or decrease the SUB LEVEL to prevent distortion and potential damage.
