Advanced AL32 Digital Audio Processing

For the ultimate fidelity with 16-bit, 20-bit and 24-bit digital audio tracks, the PMA-50 features Denons Advanced AL32 digital
audio processing system. Featured on Denons premium audiophile disc players and digital audio components, Advanced AL32
processing upconverts, digitally filters and noise-shapes lower
bit data to full 32-bits, delivering remarkable dynamic range and
noticeably better low level resolution. Your favorite digital audio
tracks have never sounded better.
DAC Master Clock Design
In order to reduce jitter, Master Clock is re-generated in the PWM
modulator. This Denon Master Clock design ensures that sound
is correctly localized and your sound space is thoroughly realistic.
Full Digital Power Amplifier for Powerful and Detailed Sound
The amplifier section incorporates DDFA technology from CSR.
The output stage circuit has a discrete construction which realizes higher Signal-to-Noise-ratio and lower distortion compared
to conventional class D amplifiers. This advanced amplifier
system delivers superior audio fidelity along with high amplifier
efficiency at 50W into 4 ohms.
The premium grade multi-way speaker connectors let you connect speaker cables via bare wire, pin connectors as well as
banana plug connectors.
USB-B Input for high resolution audio including PCM and
DSD
Via the USB-B input, you can connect your Mac or PC to the
PMA-50 and enjoy high resolution audio tracks. The PMA-50
can play high resolution PCM files up to 24-bits/192-kHz along
with high resolution DSD 2.8 MHz and 5.6 MHz files (DSD is the
advanced digital audio coding system of SACD). A USB-A to USBB cable is included.
To eliminate induced digital noise via the USB input, the PMA-50
features a dedicated noise isolation block prior to the digital amplifier and D/A conversion block that prevents digital noise from
degrading the audio fidelity.
