1Technical Highlights
Design
The audio section of the 530 is physically separated from the power supply and dig-
ital circuits. In order to reduce interferences to a minimum, these sections are addi-
tionally shielded. The power amplifier section is executed in dual-mono layout. The
left and right audio channels have their own respective identical boards to deliver a
channel separation of >105dB for a three dimensional sound stage.
Amplification
At its core is an innovative voltage amplification stage that consists of linearized
amplifiers operating up to a cutoff frequency of 80MHz. Current amplification is
done in three stages, each with a narrow, almost linear operating range.
Powersupply
Four cutting-edge switched-mode power supplies deliver 2,400W of audiophile
quality power. They feature high performance filtering at the input and output, and
six high speed soulution voltage regulators to deliver considerably more stable power
than any conventional, transformer-based technology.
Volume control
The 530’s volume control uses only high-precision, low-noise metal foil resistors,
and it controls both the volume and balance. To block switching peaks during vol-
ume changes which may be hazardous to power amps, the 530 is equipped with a
second volume control with PGA (Programmable Gain Amplifier). Active only during
the volume control process, it is similar to a potentiometer and enables the volume
to be adjusted smoothly without clicks. As soon as the new desired level value has
been selected, the unit returns control to the precision resistors.
Pre-Out
The soulution 530 integrated amplifier is equipped with pre-out connections which
enable subwoofers, tape recorders or other amplifiers to be driven directly by the
530’s preamplifier section, by-passing the power amplifier section.
Surround mode
Surround mode allows users to optimally integrate the 530 with AV systems. In sur-
round mode, the input signal by-passes the preamplifier section without any ad-
justment for volume or balance.
