•Input impedance 0 ohm
Most of currently available phono equalizers are designed to amplify the voltage that appears at both ends of a resistor when a current generated by the cartridge is carried to the ground through this resistor. Our Phonocube has a unique and original circuitry ( with input impedance of 0 ohm), which enables all of the current generated by the cartridge to flow directly into the amplifying circuit.
•Unique equalizing circuit with advantages of both NF and CR types.
Although NF type circuitry is known for its high S/N ratio, a rise in the high frequency is always inevitable. The unique equalizing circuit of Phonocube allows the same level of high S/N ratio while maintaining the smooth and accurate equalizing character of the CR type.
•Extreme simplicity --- minimum circuitry
To preserve the freshness of the sound, we reduced the number of parts as much as possible, 25 per channel, and achieved the shortest signal pass length ever (44 m/m).
•Rigid and compact chassis construction
The chassis of Phonocube is constructed from two aluminum tubular frames ( 40 x 80 m/m section ) and front and rear panels of 10 m/m thick machined aluminum. Each circuit of left and right channels is encased in a separate chassis to eliminate interference between them and to achieve ideal dual mono structure.
