DuoForte - the Fortepiano's "additional power plant"

Six Moons Review ( www.6moons.com )

This additional unit almost quadruples the power-performance of the small amp, and it also has other benefits: Higher voltage, high performance maintenance-free rechargeable batteries.

By choosing this option, the fortepiano module only powers preamp stage (preamps, control, and input selector) thus not only creates an easy connection to a multiplying increase in performance, but also realizes the special independent power source of the "pre-power amplifier" classic formula and improves sound quality as well.

The power output of Fortepiano with DuoForte is about:  2 x 48 W @ 4 Ohm load or 2 x 30 W @ 8 Ohm load

For less sensitive speakers the use of DuoForte is strongly recommended.
