The Inca 500 is a four-channel amplifier in a half-rack width format, designed to deliver maximum installation flexibility for Lo-Z and Hi-Z systems alike. Thanks to its universal power supply with integrated PFC and 1 RU height, it’s perfectly suited for AV installations, hospitality, corporate environments, and distributed systems. It can deliver 125 W per channel at low impedance (4–8 Ω) or 250 W per channel at 70/100V, making it ideal for mixed or distributed setups.

The Inca 500 features a full matrix DSP, controllable via TCP/IP, offering complete signal processing including EQ, delay, trim, polarity, and optimized presets with FIR filters and limiters. It also supports Master/Slave operation via S/PDIF, allowing multiple units to be digitally linked. Its innovative automatic power sharing function redistributes power dynamically across outputs, maximizing efficiency and adapting to system demands. Compact, efficient, and highly reliable, it’s the perfect solution for professional systems where space is at a premium.

Highlights

4x125 W on Lo-Z or 2x250 W on 70/100V, perfect for low and high impedance mixed systems

Thanks to its flexible architecture, the Inca 500 can operate in Lo-Z mode (from 4 to 16 Ω) with four 125 W channels, or in Hi-Z mode with two 250 W channels at 70 or 100 V. This dual-mode functionality allows a single device to cover a broad range of system requirements, from traditional direct-loaded speaker systems to distributed audio networks typical of commercial, public or hospitality spaces. The ability to switch between modes ensures design flexibility, making the amplifier suitable for hybrid setups or future system expansions.

Automatic power sharing technology, for intelligent redistribution of output power

The Inca 500 features a dynamic power sharing system that allows up to 250 W to be distributed across each output pair, automatically reallocating power based on the actual demand of each connected load. This means that in real-world applications—where not all channels require the same output—the amplifier can optimize resource usage, reducing energy waste and improving overall system efficiency. This is especially beneficial in zoned or distributed setups, where loudspeakers may have different load characteristics or output needs.

PFC (Power Factor Correction) for flawless worldwide operation

Highly efficient, microprocessor-controlled power supply with built in PFC (Power Factor Correction) for flawless worldwide operation with any AC mains voltage in the range 85-275 VAC tolerant to peak up to 400 V

Intelligent variable speed ventilation

Ventilation is controlled by internal temperature, with front-to-rear airflow for rack mounting.
