Usage Features
5.1+1 System: The FC730 is designed to provide a perfect acoustic effect when connected to audio sources with AC-3 or DTS decoders, offering an immersive surround sound experience.
6.5" Subwoofer: Features a 6.5" subwoofer unit with a dual Sr Magnet system. It utilizes a costly low-Q value, long-stroke program design, which contributes to quick and high-resolution low-frequency quality.
eAirbass Technology: This proprietary technology aims to enhance bass without distortion. It incorporates a brand-new airflow passage design for clearer sound and an extended frequency range. Electronic control technology ensures precise bass signal selection, crystal clear high notes reproduction, and synchronous phase control for accurate bass delivery, addressing issues like slow frequency response. The result is distortion-free, lifelike, and rigorous deep bass.
Design for Music: Microlab's R&D philosophy emphasizes a music-oriented design, drawing inspiration from European musical culture. This focus aims to deliver a high-quality listening experience for various musical tastes.
System Connection:
The system can be connected to various audio sources:
- VCD/DVD Players (Stereo): Use double RCA audio cables. Connect one end to the L/R "Aux Input" jacks on the amplifier and the other end to the VCD/DVD's audio output jacks.
- PC Sound Card or Other Audio Equipment (5.1 Channel): Use 3.5mm-2RCA audio cables (3pcs). Connect the RCA ends to the appropriate "5.1 Input" jacks (front left/right, center, rear left/right) on the amplifier, and the other ends to the corresponding audio output jacks on the sound card or other audio equipment.
- Speaker Connections: Connect the woofer, front left/right, center, and rear left/right speaker cables to their respective audio output jacks on the back of the amplifier.
- Power Connection: After all audio and speaker cables are connected, plug the power cord into a suitable AC outlet. The socket-outlet should be easily accessible.
Maintenance Features
