Volumio Primo Plus - Dual-Mono Streaming DAC

Primo Plus combines network streaming, a dual-mono DAC and hardware preamplifier control. Two ESS ES9039Q2M converters, one for each channel, operate with separate linear supply stages and a precision clock to keep analogue and digital circuitry carefully organised.

USB-C allows it to serve as a DAC for a computer, while optical and coaxial inputs connect other digital sources. Balanced XLR and RCA outputs offer selectable levels to match an amplifier or active speakers. Eight digital filters and a selectable NOS mode provide further configuration options.

An OLED display, two rotary controls and the included Remoto remote complement app control. Volumio Premium features are built in, with Ethernet and Wi-Fi for network playback. The supplied 5 V power supply makes it ready to use; an optional Lineo5 is a separate upgrade.
