4 輸入 8 輸出揚聲器管理處理器如何提升音響系統控制？

聯邦航空航太技術公司 的 4進8出揚聲器管理處理器 (Model SP‑48) is a professional audio solution designed for theatres, concert halls, discos, and installed sound systems. With 24‑bit/48kHz processing, 512‑order FIR filters, Dante connectivity options, and an intuitive TFT display, this processor delivers precise speaker control—from gain and delay to crossover and limiting. The SP series supports analog and Dante I/O, flexible routing, and PC software control via USB or RJ45. Backed by 聯邦航空航太技術公司強大的研發實力、CE/ROHS認證與全球市場 存在，此處理器可確保苛刻的專業環境可靠、高品質的音訊管理。

複雜音響系統的精確控制

Modern audio installations—whether in a concert hall, house of worship, or corporate auditorium—demand granular control over every loudspeaker. FHBAVTEC's 4進8出揚聲器管理處理器 (SP‑48) answers this need with a comprehensive suite of processing tools. It accepts four analog inputs (with optional Dante digital inputs on the SP‑48D variant) and distributes signals across eight analog outputs, each equipped with independent equalisation, delay, crossover, limiting, and gain staging. The built‑in high‑performance DSP chip, combined with 24‑bit/48kHz sampling and 110dB signal‑to‑noise ratio, ensures transparent audio quality with ultra‑low distortion (<0.002% THD+N). This processor is the ideal hub for managing multi‑speaker zones, bi‑amplified or tri‑amplified systems, and large‑scale distributed audio networks.

常見問題解答

Q：SP-48 和 SP-48D 有什麼不同？

A: SP‑48 has 4 analog inputs and 8 analog outputs. SP‑48D adds 4 Dante digital inputs (via Ethernet) while retaining the 8 analog outputs, enabling integration with Dante audio networks.

Q：我可以遠端控制處理器嗎？

A: Yes. You can connect via USB or RJ45 to use the PC control software, or use Dante Controller for network‑based routing. The processor also has RS232 and Ethernet control ports for third‑party integration.

Q：支援FIR濾波嗎？

A: Absolutely. The SP series includes a 512‑order custom FIR filter per output channel, and you can import FIR coefficients generated by third‑party software (e.g., Smaart, OpenDRC).

Q：包裝內有什麼？

答：包裝內含設備、電源線、USB 軟體線、快速指南和品質證書。

Q：我可以將其用於雙功放揚聲器系統嗎？

A: Yes. The crossover section with selectable slopes and filter types makes it ideal for bi‑amp, tri‑amp, or multi‑way speaker configurations.

Q: 你們為該處理器提供 OEM/ODM 服務嗎？

A: Yes. FHBAVTEC has extensive experience in OEM/ODM, and we can customise hardware, software, and branding according to your requirements.
