The 0-2410 inherits the superb design technology of
the 072810, including the improved AAVA(Accuphase
Analog Vari-gain Amplifier) volume control With similar
specs and conﬁguration. AAVA is a revolutionary
concept that takes a radically different approach
from conventional volume controls. The result is
high performance and sound quality far exceeding
AAVA does not use variable resistors, which brings
a number of distinct advantages: ® Frequency
response does not change, regardless of the volume
setting. ® S/N ratio is outstanding. © Distortion is
reduced to an absolute minimum. Qt) There are no
left/right level differences (tracking error). (9 Left/right
channel crosstalk is minimized. Another beneﬁt of
AAVA is the fact that only highly reliable electronic
components are used. Mechanical wear ceases
to be a problem, ensuring that the outstanding
performance and sound quality of the amplifier will
remain undiminished for many years to come. Unlike
conventional digital volume controls, AAVA operates
through purely analog processing. The operating feel
using a volume knob on the front panel also is exactly
the same as With other high-end stereo components.
The power supply section of the 0-2410 employs
two separate transformers, one for each channel.
Filtering capacitors and all other parts of the power
supply are duplicated for left and right. Whats more,
the AAVA circuitry, balanced output circuits, and other
unit amplifiers are also entirely separate for the two
channels, arranged on a highaquality motherboard.
This fully monaural construction prevents unwanted
crosstalk and interaction both on the electrical and the
As can be expected of a control center, the
C-2410 offers a full complement of balanced and
unbalanced input and output connectors. Flexibility is
further enhanced by features such as tone controls,
loudness compensation, recorder functions, subsonic
filter, overall gain selection, EXT PRE connectors
for combination With another preamplifier, and
independent phase selection for each input position.
