A Dual-Channel Commercial Power Amplifier with SIP and Dante Support
voip-gateways

The ZYCOO SD Series Network Power Amplifiers — comprising the SD260 and SD2140 — are purpose-built for commercial audio applications, leveraging advanced Class-D amplification technology to deliver crystal-clear audio and outstanding reliability.

Both models support constant voltage 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.

Additionally, the amplifiers are equipped with a real-time adjustable mixer, an equalizer, and support scheduled playback via USB storage devices, making them ideal for scalable, intelligent audio deployments.

10-Band Frequency Equalizer

The EQ feature of the SD260 and SD2140 supports a 10-band frequency adjustment, allowing precise optimization of different frequency ranges for audio sources such as multicast, event scheduler playback, and local line inputs. Users can create and manage multiple equalizer profiles, easily applying them to various audio sources and channels.

Standard SIP Supported

Both SD260 and SD2140 support the standard SIP protocol and can integrate seamlessly with ZYCOO IP Audio Center or third-party SIP servers, such as IP-PBX systems. Unlike traditional power amplifiers, which rely on dedicated hardware or complex setups for paging, they enable SIP paging directly to connected analog speakers via networks, simplifying deployment and management.
Standard SIP Supported

Dante™ Compatibility

Dante™ delivers uncompressed, multi-channel, low-latency digital audio over a standard Ethernet network. The SD260 and the SD2140 come with Dante™ functionality. Once enabled, you can seamlessly join the Dante™ audio network and use Dante™ to play audio with low latency to the audience.
