Product Description
• It adopts a new compact design with an aluminum alloy integrated front panel and a chassis formed by high-strength sheet metal stamping.
• The front panel features a power switch, independent channel gain control knob, and status indicator lights.
• Each channel has separate protection indicator lights, clipping indicator lights, signal indicator lights, and power indicator lights, which can display the working status of the amplifier channel.
• It is equipped with 2 audio input interfaces and 2 audio loop-out interfaces.
• It has a 1.44V and 0.775V input sensitivity selection switch.
• It has a working mode selection switch that supports stereo and parallel modes.
• It supports the expansion of AES67 and DANTE network audio terminals for audio network transmission.
• It adopts an H-class HiFi-grade fever circuit, low-noise IC, and high-precision resistance and capacitance components, resulting in high sound reproduction.
• It has short-circuit, overheat, overload, overcurrent, output DC, resonant soft switch startup, and current fuse protection, as well as transformer overheat protection.
• It has a linear voltage-regulating circuit with overvoltage protection. When the load is below the rated range, it intelligently controls the output power, maintains constant power within a safe range, and ensures the reliability and safety of the amplifier.
• It adopts automatic temperature compensation technology and supports intelligent temperature measurement and adjustment. Combined with a high-density copper radiator and internal fan forced cooling, it ensures stable operation of the equipment for a long time.
• It uses a wide operating voltage range of 180V~250VAC and has built-in power management embedded software that can monitor voltage status, avoid equipment failures caused by voltage fluctuations, and achieve all-weather protection.
