Description: Denon's first network playback compatibleFull-size Hi-Fi integrated amplifierMain features New generation Advanced High Current single push-pull amplifier circuitUltra-low noise variable gain preamplifier & high-precision electronic volume controlPowerful power circuit using newly developed block capacitorsMM/MC compatible phono equalizerEquipped with HEOS to realize the latest network audio functionsUses many high-quality parts inherited from the PMA-A110 and dedicated custom partsA/B switching compatible gold-plated speaker terminalsNew generation Advanced High Current single push-pull amplifier circuitIn order to achieve the most important theme in Denon's audio amplifier design, "combining delicacy and power," we have adopted a simple circuit that uses HC transistors with a peak current supply capacity three times that of general transistors in a single push-pull. In order to solve the problem of muddy sound caused by the variation in element performance, which is a problem in the method of driving many elements in parallel to obtain large currents, and to achieve the expressive power that delicately depicts even the expression of musical sounds, Denon has continued to focus on amplification with the smallest unit of elements, one pair. The PMA-900HNE follows the configuration of the Denon 110th anniversary model "PMA-A110", and adopts a differential two-stage amplifier circuit that is more stable against oscillation than the conventional differential three-stage amplifier, resulting in a more straightforward sound quality. The high current output of HC transistors and highly stable circuit configuration drive a variety of speakers accurately and powerfully. Ultra-low noise variable gain preamplifierThe PMA-800NE used a single-stage amplification by a high-gain amplifier, but the PMA-900HNE uses a two-stage configuration with a variable gain preamplifier and power amplifier, just like the PMA-A110. By increasing or decreasing the gain of the preamplifier according to the volume, the noise level is dramatically improved by amplifying only with the power amplifier without amplifying with the preamplifier within the range of commonly used volumes. It has achieved an extremely delicate and transparent spatial expression. High-precision electronic volume controlThe PMA-900HNE uses a high-precision electronic volume control IC, just like the PMA-A110. The sensor detects the direction and amount of rotation of the knob, and based on that information, the volume is controlled by a highly accurate electronically controlled volume mounted on the main board. The same configuration is used for the left/right balance and tone controls. This makes it possible to shorten the signal line that went back and forth between the knob on the front panel and the preamp board, achieving an ideal minimum signal path. Powerful power supply circuit with newly developed block capacitors To maximize the capabilities of the Advanced High Current single push-pull circuit, the power supply circuit uses a large EI core transformer and a large-capacity (8,200μF) block electrolytic capacitor newly developed specifically for the PMA-900HNE, as well as a Schottky barrier diode with fast switching speed and low rectification noise. The generous power supply capacity supports bass reproduction that combines weight and tightness beyond its class. MM/MC compatible phono equalizer Equipped with a phono equalizer that supports both MM/MC cartridges. Phono equalizers have high gain and are easily affected by loops in the pattern, so sound quality can be significantly improved by thoroughly simplifying and straightening the circuit. By using a relay to switch between MM and MC, delicate analog signals can be amplified more purely without the need for extra signal lines on the board. The PMA-900HNE also upgrades the op amp to a higher quality one. TV auto play functionThe optical and coaxial digital inputs are equipped with an auto play function that automatically turns on the power when an input signal from an external source such as a TV is detected. You can select one of the four inputs or turn the function off. Equipped with HEOS to realize the latest network audio functionsEquipped with the network audio platform "HEOS", which is used in various Denon audio products such as network speakers, sound bars, and AV amplifiers. It can play a variety of audio sources, including streaming services and Internet radio, music servers on the local network (NAS / PC / Mac, etc.), audio sources stored on USB memory, smartphones, tablets, and Bluetooth® devices. You can also distribute the music being played on this unit to other HEOS Built-in devices connected to the same network. Anyone can easily set up and operate it with the free HEOS app, and it also supports voice control by Alexa. Compatible with a wide range of music streaming services and Internet radioCompatible with a wide range of music streaming services* such as Amazon Music HD, AWA, Spotify, and SoundCloud. With streaming services, you can not only select and play your favorite artists' songs as before, but also enjoy a wide variety of playlists that can be selected by music genre, era, mood of the day, etc., from the latest songs to classic songs of the past, so the possibilities for encountering new music are endless. You can also enjoy Internet radio from all over the world, including music, talk, and news. It supports broadcasts distributed in MP3, WMA, and AAC formats, and you can easily search the "TuneIn" database based on genre, region, language, etc. * Separate registration, contract, and fees may be required to use the service. Compatible with Amazon AlexaCompatible with voice control by Amazon Alexa. In addition to basic operations such as play, stop, skip, and volume adjustment, you can play songs from Amazon Music by specifying the song name, artist name, era, genre, etc. by simply talking to an Alexa-enabled device such as Amazon Echo. You can also call up Internet radio stations by voice. Amazon Alexa logo Supports 5.6 MHz DSD & high-resolution audio sources Supports playback of DSD files and high-resolution audio sources stored on music servers and USB memory. DSD files can be played up to 5.6MHz, and PCM files can be played up to 192kHz/24bit. In addition, it also supports gapless playback of DSD, WAV, FLAC, and Apple Lossless files. There is no interruption in sound between songs even when listening to classical music or live albums. AirPlay 2 compatible Supports "AirPlay 2", which allows you to easily play music from iPhones, iPads, Macs, etc. You can enjoy Apple Music and app audio on the PMA-900HNE. It also supports multi-room playback with multiple AirPlay 2-compatible devices. In addition, if you add the PMA-900HNE as an accessory on the "Home" app, you will be able to play Apple Music* and songs from your iPhone library using voice control by Siri. *Separate registration, contract, and fees may be required to use the service. Bluetooth reception functionSupports wireless music playback from Bluetooth (A2DP profile) compatible devices such as smartphones, tablets, and PCs. Since it also supports the AVRCP profile, you can use the unit's remote control to perform operations such as play, pause, and skip. It can be paired with up to eight Bluetooth devices. Ultra-low phase noise clock that minimizes jitterIn digital audio playback, the accuracy and low jitter of the clock signal that serves as the basis for the circuit's operation are the keys to performance. In order to improve the accuracy of the clock supplied to the D/A converter, an ultra-low phase noise clock oscillator is placed near the D/A converter to minimize jitter. Uses many high-quality parts and dedicated custom parts inherited from the PMA-A110In addition to following the circuit configuration of the PMA-A110, the PMA-900HNE uses the same parts as the PMA-A110 for some of the parts used in the audio circuit, such as capacitors and resistors, which are not normally used in products of this grade. During the development process of the PMA-SX1 LIMITED EDITION and PMA-A110, Denon's custom parts, which were created by sound quality engineers and sound masters through repeated prototyping and listening, were used to achieve Denon's ideal "Vivid & Spacious" sound. Thorough high-frequency noise countermeasures The digital audio circuit is enclosed in a shielded case to suppress the impact of high-frequency noise generated by the digital audio circuit that handles the digital audio signal input through the network, USB, and Bluetooth on the analog audio signal. In addition, a decoupling capacitor is used to remove noise from the power line. In addition, the sound quality is summarized using various accumulated know-how, such as optimizing the ground impedance by changing the type of screws and washers that secure the board and chassis depending on the location of use. Ribbed high-density feet that suppress vibration The feet that support the large weight of the power transformer, heat sink, and chassis use high-density, highly rigid ribbed feet. This further enhances the vibration-proofing effect and also provides careful sound quality tuning. Gold-plated speaker terminals with A/B switchingThe speaker terminals of the PMA-900HNE are gold-plated to prevent deterioration over time, ensuring high reliability over the long term. They are also compatible with banana plugs. The two speakers support A/B switching and simultaneous output of two systems, allowing you to switch between two speaker systems or make bi-wiring connections.
