The black Denon PMA-50 2-Channel Digital Integrated Stereo Amplifier supports wireless audio streaming and high-resolution audio. This integrated amplifier features a digital design and delivers up to 25W per channel at 8 ohms and 50W per channel at 4 ohms. In addition to stereo speaker connectivity, the PMA-50 features a subwoofer output for connecting an external powered subwoofer speaker. With integrated Bluetooth with NFC connectivity, this integrated amplifier can wirelessly stream audio from compatible devices such as smartphones, tablets, and PCs.
Expanding upon the PMA-50's wireless connectivity, wired stereo RCA, digital coaxial, and dual digital optical inputs are also onboard. These interfaces allow you to connect audio sources like CD players. There's even a USB-B input, which supports high-resolution audio tracks from compatible sources. As an added convenience, a USB cable is included. The PMA-50 also includes an ergonomic remote control and its 7.9" wide chassis supports both horizontal and vertical placement.
Advanced AL32 Digital Audio Processing
For high-fidelity 16-bit, 20-bit, and 24-bit digital audio tracks, the PMA-50 features Denon's Advanced AL32 digital audio processing system. Advanced AL32 processing upconverts, digitally filters, and noise-shapes lower bit data to full 32-bits for enhanced audio reproduction.
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, for realistic sound quality.
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 is designed to deliver high-fidelity audio along with high amplifier efficiency at 25W per channel at 8 ohms. The premium-grade multi-way speaker connectors let you connect speaker cables via bare wire, pin connectors, or 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 USB-B cable is included to help eliminate induced digital noise via the USB input. The PMA-50 also 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.
Bluetooth Wireless Connectivity with NFC and Multi-Point
Stream your favorite audio tracks from your portable devices via the PMA-50's Bluetooth connectivity, which features quick and easy pairing via the Bluetooth button on the front panel. Simply activate the Bluetooth function on your device, press the Bluetooth
button on the front panel or the remote control and when prompted, enter the supplied 4 digit passcode on your device.
Your device and the PMA-50 are instantly paired and up to 8 devices can be remembered. For even faster pairing, the PMA-50 features NFC (Near Field Communication). Simply activate your NFC-enabled Bluetooth device and place it next to the N mark on the PMA-50 (located on
the side panel), and it's instantly paired with no need for manual passcode entry.
Furthermore, the PMA-50 features multi-point Bluetooth connectivity that allows 3 Bluetooth-enabled devices to be connected simultaneously. It plays tracks from 1 device and when it's paused or stopped and another paired device's play function is activated,
the PMA-50 automatically switches to that device. The front panel display shows the name of the currently selected Bluetooth device.
aptX Low Latency Decoding
For CD-quality audio playback, the PMA-50 features CSR aptX Low Latency decoding, which provides optimum time synchronization when playing back audio from video sources with no lip sync issues.
Compact Chassis with Vertical or Horizontal Placement
The compact chassis features a soft aluminum matte finish with bright silver tone accents
and glossy and matte black surfaces. For optimum placement versatility, the PMA-50 can be positioned either horizontally or vertically and it features removable feet and screw caps that are quickly and easily re-configured.
Clear View OLED Display
The integrated OLED display shows the source selected via graphical icons and text, as well as the sampling frequency and data format of digital sources. The PMA-50 also features an automatic display orientation function that detects if the amplifier is mounted vertically or horizontally and adjusts the display accordingly.
High-Quality Headphone Output with Selectable Headphone Impedance
The PMA-50 is equipped with a dedicated headphone amplifier circuit that features a high-speed, low-distortion wideband op amp that's paired with a fully discrete final output stage.
In order to accommodate a wide range of headphone types, the PMA-50 features an adjustable headphone impedance control, with 3 settings for low, medium, and high impedance headphones,
which provide proper matching of headphone impedance and amplifier gain. The headphone jack features a 3.5mm connector for compatibility with home and professional studio headphone
Ergonomic Remote Control
The supplied remote control features an ergonomically-designed layout that includes a cursor keypad, source select, volume controls, setup menu, back buttons, a Bluetooth button, and a
display dimmer button.
USB-B DAC for computer-direct connectivity and high-resolution audio reproduction
Auto Standby and low power consumption at stand-by (0.2W)
