A-933
[Integrated Amplifier]
Low-Impedance, Thick Bus Plate and Separate Toroidal Transformers
The A-933’s transformers are separated for both + and – power sources.
Through the thickness of the transformer’s coil and by the sheer size of the
transformers, it is possible to significantly reduce impedance. Also, the thick bus
bar plate diminishes fluctuations in the electrical potential and eliminates ground
hum for more efficient power distribution, reduced noise and crisper sound.

Selectable A/B Speaker Outputs
With two sets of two-channel speaker outputs on the rear panel, it is possible to
set up two separate environments for playback. Through the use of the Speaker A
and Speaker B buttons on the front panel, each zone can be instantly selected or
both can engaged for enjoyment in both zones.

All Discrete Output Stage Circuitry
Mini-systems made by our cost-cutting competitors typically employ just one
circuit at the output stage. With multiple transistors crammed onto this single
circuit, excess heat is generated and the audio signal is compromised. The
A-933, though, uses discrete amplifier technology similar to that found on our
high-end receivers. Keeping the transistors separate at the output stage enhances
cooling, so that the amplifier’s longevity is extended and unwanted interference
to the audio signal is reduced.

VLSC (Vector Linear Shaping Circuitry)
Conventional D/A conversion methods reduce digital pulse noise at the conversion
stage but can’t remove it completely. Using a similar process to VL Digital
technology, VLSC generates a pure analog signal from the digital signal ensuring
that sound quality from CD, CD-R/RW and MP3 CD is optimized.

technology, VLSC generates a pure analog signal from the digital signal ensuring
that sound quality from CD, CD-R/RW and MP3 CD is optimized.
Exclusive Direct Digital Path
Unlike other CD players that use PC-copper board traces to transfer the digital
audio signal, the C-733 CD player employs a high-purity, heavy-gauge shielded
cable to directly output the digital bitstream straight from the disc to the back
panel. The result is a noise-free digital audio signal that is less susceptible
to flux.

Cirrus Logic 192 kHz/24-Bit Digital-to-Analog Converter
Onkyo engineers have incorporated the Cirrus Logic CS4396 high-performance
192 kHz, 24-bit digital-to-analog convertor (DAC) in the C-733 because it
best serves our design philosophy: the substantial reduction of both noise and
signal distortion. We also found that
it integrates effectively with Vector
Linear Shaping Circuitry (VLSC). This
DAC has a multi-bit architecture that
significantly lowers out-of-band noise
and jitter sensitivity than traditional
1-bit designs, and it also enables
low noise and distortion at all signal
levels. Another advantage of this
DAC is that it enables the C-733 to
achieve a dynamic range of 96 dB.

High-Precision Loading Mechanism
Onkyo engineers have found that vibrations caused by the rotating disc and
mechanism can significantly deteriorate playback quality, which is why they
developed a high-precision loading mechanism. Conceptually, as vibration is
controlled within a musical instrument for tone and timbre, this loading mechanism
is designed to eliminate unnecessary vibration.

Digital Servo for Optimum Servo Amounts
The C-733’s Digital Servo Control maintains stable tracking, laser focus, and disc
rotation—all with higher precision and lower radiated noise than non-servo units.
