MUSICBOOK POWER 500/1000
MONO BEATS STEREO
A unique feature of the Musicbook POWER is the possibility to run one power amp per channel in “vertical bi-amping" mode. This requires a loudspeaker with separate connections for the bass and the high/midrange. Each range is driven by a proprietary power amp. The result is a clear improvement in sound quality in the fundamental range and an enhanced overall transparency of reproduction. In most cases the bass range will equally benefit from this.
In bi-amping mode the Musicbook POWER offers a level control for the bass which is now adjustable in ten steps. This feature is a real problem solver in many living rooms. Depending on the speaker placement less can be more here! This is especially true of large speakers which are difficult to
The Musicbook POWER is a top-level class-D amplifier. This "N-Core" design (a reference to "encore") is nothing but a revolution in this field. The measured values of these amplifiers are remarkable for several reasons: very low distortions, an extremely high damping factor and a linear frequency response up to 45 kHz.
Even more important is the fact that the distortions will not increase at high modulation or towards high frequencies, and the frequency response does not depend on the speaker impedance. Hence the connected loudspeaker does exactly what it’s supposed to do. It is controlled perfectly. The result is a supremely musical reproduction without any resonances or colorations.
