The D 3045 is a compact integrated amplifier that combines a HybridDigital power stage with a digital-to-analogue converter. It is rated at 60 W per channel into 4 and 8 ohms, with a clipping power above 80 W and IHF dynamic power of up to 200 W into 2 ohms. It is aimed at smaller listening rooms, desktop systems and TV-based setups.
Digital sources connect through an asynchronous USB input that handles up to 24-bit/384 kHz from a computer, plus optical and coaxial inputs for up to 24-bit/192 kHz. MQA and DSD playback are supported from compatible sources. An HDMI ARC input lets a television send audio to the amplifier with simple control, and Bluetooth with aptX HD covers wireless streaming. A Moving Magnet phono stage is included for turntables.
For system expansion, the unit has a pre-out and a subwoofer output, so it can feed a subwoofer or an external power amplifier. A dedicated headphone amplifier is built in for private listening. Standby power draw is below 0.5 W, and the enclosure measures 70 x 235 x 265 mm.
