The dCS Rossini APEX DAC represents a significant leap forward in digital audio playback, integrating dCS’s most advanced digital technologies into a single, elegant chassis. At its heart lies the revolutionary dCS Ring DAC™ APEX hardware, a re-engineered version of their proprietary digital-to-analog conversion system. This APEX iteration features a reconfigured circuit board and an entirely new analog output stage, resulting in measurable improvements in linearity and a dramatic reduction in distortion, leading to an even greater sense of dynamic drive, detail, finesse, and vitality in the sound.

More than just a DAC, the Rossini APEX is a complete digital hub, incorporating a high-performance network streamer that is Roon Ready and offers integrated access to services like TIDAL, Qobuz, and Spotify. It supports high-resolution PCM up to 24 bit/384 kHz and DSD128, along with full MQA decoding. Its extensive array of digital inputs, including USB, AES/EBU, S/PDIF, and optical, ensures compatibility with virtually any digital source, while versatile analog outputs (balanced XLR and unbalanced RCA with selectable output levels) allow direct connection to a power amplifier. Designed to be enhanced by the optional Rossini Master Clock for ultimate timing precision, and controlled intuitively via the dCS Mosaic app, the dCS Rossini APEX DAC delivers an unparalleled, highly resolving, and deeply musical experience, setting a new benchmark for integrated digital playback.

Digital Inputs
Network interface on an RJ45 connector Acts as a UPnPTM renderer in Asynchronous mode, streaming digital music from a NAS or local computer over a standard Ethernet network, decoding all major lossless formats including FLAC, WAV & AIFF at up to 24 bit 384kS/s native sample rate, plus DSD/64 & DSD/128 in DFF/DSF format.
Other supported formats include WMA, ALAC, MP3, AAC & OGG.
Some formats are limited to lower sample rates. Accepts data streamed from an iPod, iPhone or iPad via Apple AirPlay, 44.1 or 48kS/s only. Network Loop Out connector on a second RJ45 connector. USB 2.0 interface on a B-type connector operating in Asynchronous mode, will accept up to 24 bit PCM at up to 384kS/s plus DSD/64 & DSD/128 in DoP format. Operates in Class 1 or 2 mode.
USB-on-the-go interface on type A connector operating in Asynchronous mode, streams digital music from a flash drive at up to 24 bit 384kS/s plus DSD/64 or DSD/128.
2x AES/EBU on 3-pin female XLR connectors.
Each will accept PCM at up to 24 bit 192kS/s or DSD/64 in DoP format. Used as a Dual AES pair, it will accept PCM at up to 384kS/s, DSD/64 & DSD/128 in DoP format or dCS-encrypted DSD.
2x SPDIF on 1x RCA Phono and 1x BNC connectors. Each will accept PCM at up to 24 bit 192kS/s or DSD/64 in DoP format. 1x SPDIF optical on a Toslink connector will accept PCM at up to 24 bit 96kS/s.
Analogue Outputs Output levels: 0.2, 0.6, 2V or 6V rms for full-scale input, set in the menu. Balanced outputs: 1 stereo pair on 2x 3-pin XLR male connectors (pin 2 = hot, pin 3 = cold). These outputs are electronically balanced and floating. Output impedance is 3Ω, maximum load is 600Ω (10k-100kΩ is recommended).
Unbalanced outputs: 1 stereo pair on 2x RCA phono connectors.
