Know before you buy
The HV technology allows the internal circuitry to operate at much higher voltages than standard designs. This results in significantly lower distortion, improved linearity, and a wider dynamic range, ensuring the signal remains pristine even at high output levels.
The unit does not come with a phono stage as standard, but it is designed to support an optional high-quality phono module. This allows you to integrate your turntable directly into the system while maintaining the preamplifier's high-fidelity signal path.
By eliminating coupling capacitors from the signal path, the P 3100 HV avoids the phase shifts and frequency limitations often introduced by these components. This results in a more transparent, stable, and accurate sound reproduction.
Yes, the P 3100 HV is highly versatile, featuring 7 unbalanced RCA inputs and 4 balanced XLR inputs. This allows you to connect a wide variety of source components while maintaining optimal signal integrity for each.
The fully symmetrical double-mono design physically and electrically separates the left and right channels. This configuration virtually eliminates crosstalk and interference between channels, resulting in superior stereo imaging and a more expansive soundstage.
Absolutely. With a total harmonic distortion of less than 0.001% and a high signal-to-noise ratio, the P 3100 HV is engineered to provide an exceptionally clean and uncolored signal, making it an ideal choice for high-resolution, sensitive audio setups.
