harmonic distortion (THD):
5 Hz a 500 KHz
÷ 125 / 200 ÷ 240 V (50 ÷ 60 Hz)
(L x H x P):
x 105 x 420 mm
further two buffers are dedicated exclusively to tape-recorder outlets.
Every outlet is characterized by an extremely low impedance which guarantees
the assured piloting of whatever power amplifier that one wants to use.
These important circuit features over and above their unquestionable technical
importance, translate into the dynamics of exceptional listening, and give
a natural and clean sound, absent of all distortion. The output signal is
released through a very high quality capacitor, of such quality that as
a result of the research carried out by the design engineer G. Mariani,
results in being the very best capacitor ever used in the field of audio.
These, in brief, are the innovations which distinguish the GRAAF preamplifier
GM13.5 B II but it should not be forgotten that the common circuit base
of all GRAAF amplifiers, like that of the GRAAF GM1 3.5 B II incorporates
interstage connections, DC coupled, completely differential circuitry, free
from any type of negative feedback.
