Advanced Direct Construction
LX83

LX53
Less is more in circuitry design. Advanced Direct Construction
allows the shortest and simplest signal paths — from input to
output, circuit block by circuit block — to reduce distortion that
can be caused by transmission loss, and to improve sonic
clarity.

3D Space Frame Construction

The latest A/V receivers inherit the separated construction
concept of Pioneer's flagship SC-LX90 pre-main amplifier. The 3D
Space Frame Construction is developed together with the rigid
trans-stabilizer to clearly define the mechanical grounding of
the chassis and make the structure strong enough to support
heavy weight. Perfected by repeated CAE strength analysis and
tests, this technology allows each part to deliver maximum
performance. Interference is also reduced by separating and
insulating the power supply, amp, analogue circuit, digital
circuit and video sections from one another.
The SC-LX83 and SC-LX73 come with this Advanced 3D Space
Frame structure, featuring precise framework design,
separating the power supply block, and isolating the analogue
video/audio and digital functional blocks into specific
compartments. This reduces interference by flat cables between
the blocks and improves the operating characteristics to
accurately reproduce even the most delicate signals.
Refined Preamp for Quality Sound
LX83
LX73
LX53
The wiring in the preamp section has been refined, with the
wire length nearly halved from the previous model to minimise
noise.
Independent Power Supply System
LX83
LX73
LX53
The analogue and digital power supply are separated to
eliminate interference between the two, and to provide clean
power to the analogue circuit, while bringing out maximum
performance from the power amplifier for quality sound
reproduction.
