A Dual-Channel Class-D Amplifier with SIP, Dante, and ONVIF Support
The ZYCOO SD Series Network Power Amplifiers — comprising the SD260 and SD2140 — are purpose-built for commercial audio applications, including corporate offices, hospitality venues, retail spaces, and educational facilities, leveraging advanced Class-D amplification technology to deliver crystal-clear audio and outstanding reliability.
Both models support constant voltage (100V/70V) and constant impedance speaker configurations. The SD260 delivers 2 × 60W or 1 × 120W (bridged), while the SD2140 offers higher output at 2 × 140W or 1 × 280W (bridged). Each model features a versatile range of inputs, including balanced/unbalanced line, Bluetooth, and network sources. With compatibility for SIP, Dante, and ONVIF protocols — no additional modules required — they offer a comprehensive, feature-rich solution.
Darüber hinaus sind die Verstärker mit einem in Echtzeit einstellbaren Mischer und einem Equalizer ausgestattet und unterstützen die zeitgesteuerte Wiedergabe über USB , wodurch sie sich ideal für skalierbare, intelligente Audioinstallationen eignen.
