DDA120 Powerful Integrated Digital Amp with Bluetooth Receiver
Powerful Integrated Digital Amp with Bluetooth Receiver
DDA120 was developed for one simple purpose: To allow you to enjoy music from any source in fantastic quality. Its diminutive size and elegant styling conceal a sophisticated amplifier capable of extracting every last detail and nuance from your music collection. The DDA120 builds on the success of its predecessor the critically acclaimed, multi award winning DDA100.
Free your digital music collection - connect wirelessly via Bluetooth to play music stored on your smartphone or tablet, stream music from services such as Spotify or listen to your favorite music service. Additionally four digital inputs enable you to connect all your other digital devices making the DDA120 the hub of your digital music system. The minimalist Direct Digital architecture maintains the purity of your digital music - resulting in a perfectly transparent, dynamic and exquisitely detailed sound.
Whether playing your vinyl collection, hooking up an FM tuner or another non-digital source, your analogue music is treated with respect. Using an ultra-high quality conversion process it follows the same minimalist processing as your digital music and so maintains its original distinctive character.
Power and Control
Any hi-fi speakers you choose will be driven with ease. The massive power available is used to effortlessly control your speakers with astounding precision ensuring you hear the recording exactly as the artist intended.
For the very highest wireless Bluetooth sound quality the DDA120 supports aptX and AAC.
AptX allows music signal to be sent wirelessly in significantly higher quality than that available from standard Bluetooth. Standard Bluetooth codec (SBC) has variable performance and its weaknesses are very apparent to music lovers including a reduction in high end clarity, muddiness or dullness. The aptX codec works to ensure consistently excellent quality when music data is transferred wirelessly via Bluetooth connection with almost CD quality. Your will instantly experience significantly greater dynamics and infinitely more detail from the music.
AAC (Advanced Audio Coding) was designed to achieve better sound quality than MP3 at similar bit rates. Unlike aptX, it is supported by iOS devices. Apple implements AAC over Bluetooth at about 250 kbps - near CD quality.
Using the innovative Direct Digital architecture for digital inputs there are no analogue stages in the signal path, keeping music in the digital domain right up to the amplifier speaker outputs. There is no separate DAC, pre-amp or power amp stages. The PWM power amplifier stage is modulated directly by the incoming signal, and the digital-to-analogue conversion takes place at the speaker outputs. In effect, the PWM power amplifier stage operates as a power DAC. Fewer component parts and less conversion processes result in a more direct, purer signal path. The Direct Digital Architecture utilizes a 176.4 kHz input sampling rate with an over-sampling rate of 3GB/s for smoother, more natural reproduction. An on-chip clock reference signal is used for synchronizing and re-clocking incoming digital audio data for exceptionally low jitter performance.
Analogue inputs are sampled using a 24-bit, 96 kHz conversion process before being fed into the Direct Digital architecture.
The amplifier delivers 75Wrms into 4 Ohms with a remarkably linear frequency and phase response of +/- 0.1dB from 20 to 20kHz, and a THD+N of 0.07% with an A-weighted signal-to-noise ratio of greater than 95dB.
