Enjoy enhanced stereo audio with your favorite speaker system and the Denon PMA-A110 110-Year Anniversary Edition Stereo 160W Integrated Amplifier. It outputs up to 80W per channel at 8 ohms and features a digital coaxial, three optical, and four stereo RCA inputs. One RCA input is designated for pre-amp connectivity, so you can use the PMA-A110 to drive the front speakers in your home theater system. A rear USB-B port lets your computer connect directly to the onboard DAC. The amplifier has a series of construction features designed to reduce unwanted noise, vibration, and interference for clear audio.
Features
80W per Channel at 8 Ohms
The PMA-A110 is designed to provide all the power you’ll need for most bookshelf and floorstanding speakers, delivering up to 80W per channel at 8 ohms and supporting 4- to 16-ohm speakers for enhanced operational stability.
Designed to Provide a Premium Listening Experience
The PMA-A110 features aluminum feet and a double-layer steel transformer plate crafted for precision and refinement.
7th Generation Advanced UHC-MOS Single Push-Pull Circuit Design
The onboard Advanced UHC (Ultra-High Current)-MOS Single Push-Pull Circuit design combines with a differential two-stage amplifier circuit to drive nearly any speaker configuration with augmented sound quality. To enhance the balance between the delicate details of music reproduction and the vigor of low-frequency sound, the PMA-A110 can deliver a massive current output in a single push-pull configuration to drive even demanding speakers and help ensure integrity in the output stage.
High-Precision Electrical Controls
The electrical volume, balance, and tone controls of the PMA-A110 are engineered to preserve the analog feel. An MCU measures the position of the knob and converts that position to control the master volume digitally to provide a smooth, linear control of the master volume by adjusting the curve of the analog volume control in the digital world. The same configuration is used for the balance and tone controls.
Onboard USB DAC
To accurately synchronize its digital circuits, the PMA-A110 has a USB DAC that supports Hi-Res audio, up to 384 kHz / 32-bit PCM and 11.2 MHz DSD. The DAC helps suppress jitter and ensure optimal precision in D/A conversion. Additionally, the DSD transmission methods support WASAPI, ASIO native playback, and DSD Audio over PCM Frames (DoP). The DAC is designed to deliver a clean, high-grade sound.
DAC Master Clock Design
To accurately synchronize digital circuits and the four audio DACs, the Master Clock Design adopts a Dual Low Phase Noise Oscillator, which positions the master clock immediately adjacent to the DACs, suppressing jitter and ensuring optimal precision in D/A conversion. The PMA-A110 also uses a clock oscillator to dramatically reduce phase noise that can cause displacement of frequencies, plus two clock oscillators – one for each sampling frequency (44.1 and 48 kHz) – that can be switched between the frequencies to more thoroughly suppress jitter.
Digital Isolator and Pure Analog Mode
The PMA-A110 is equipped with a high-speed digital isolator circuit between the digital and analog sections to help avoid any interference from the digital circuitry in the analog section. It also features three independent power supplies to help ensure complete isolation for each section and avoid interference. When the amplifier is set to Pure Analog Mode, it turns off all the digital circuits, including the fluorescent display, to help provide clear reproduction of the analog input signal and remove any electrical disturbances that may adversely affect your listening experience.
