HIGH-END PERFORMANCE, STRAIGHT OUT OF THE BOX
 
PRECISO is ready to plug and play into your digital audio chain. Whether you’re pairing it with a Volumio RIVO or another transport, it integrates seamlessly with any hi-fi setup.
 
 
PRECISION MEETS VERSATILITY
 
PRECISO combines hyper-symmetrical dual mono DACs, independent analog/digital power regulation, and precision MEMS clocking—all to create an exceptionally clean and natural sound. Use it as a DAC or as a pre-amp with integrated hardware gain control for direct connection to your power amplifier.
 
 
NEXT-LEVEL AUDIO ARCHITECTURE
 
Hyper-Symmetrical Dual Mono SABRE DACs
Dual ESS ES9039Q2M chips in a perfectly mirrored design eliminate crosstalk and ensure lifelike imaging and soundstage.
Dual Linear Power Supply Architecture
Separate linear regulation for analog and digital paths guarantees a noise-free signal and optimal dynamic range.
Precision MEMS Clock & Premium Components
A high-accuracy MEMS clock drives both DACs for ultra-low jitter, combined with high-grade OPAMPs and an ASIC USB interface for flawless data transfer.
 
 
PURE, FLEXIBLE AUDIO CONTROL
 
With a built-in hardware gain control ranging from 0.0 dB to -99.0 dB in 0.5 dB steps, PRECISO removes the need for an external pre-amp—providing ultimate convenience and high-fidelity performance.
 
 
READY FOR MODERN AUDIO SOURCES
 
PRECISO supports high-resolution formats up to 32-bit/768 kHz PCM and DSD512, with connectivity options including:
 
USB
S/PDIF (coaxial and optical)
I2S/DSD over HDMI
Balanced XLR and Unbalanced RCA outputs
 
 
OPTIMAL PAIRING WITH RIVO+
 
Preciso shares the same dedicated USB interface as RIVO+, ensuring pristine signal flow and tight timing accuracy when paired—making it an essential component of a fully optimized Volumio ecosystem.
 
 
BUILT FOR SONIC EXCELLENCE
