Type- Upsampling Network DAC with Headphone Amplifier

Converter Type- dCS proprietary Ring DAC™ topology.

Digital Inputs-
Network interface on an RJ45 connector – acts as a UPnP™ 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 formats include WMA, ALAC, MP3, AAC & OGG. Some formats are limited to lower sample rates. Supports Apple AirPlay at 44.1 or 48kS/s. 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. 2x AES/EBU on 3-pin female XLR connectors. Each will accept PCM at up to 24 bit 192kS/s or DSD/128 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. 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. Output impedance is 52Ω, maximum load is 600Ω (10k-100kΩ is recommended).

Headphone Outputs-
1 stereo balanced pair on 1x 4-way male XLR connector. 1 stereo unbalanced pair on 1x 6.35mm (1/4”) 3-pole jack. Full-scale output levels are 1.4W rms into 33Ω, 0.15W rms into 300Ω. Output levels are 0, -10, -20, -30dB, set in the menu. Minimum headphone impedance is 33Ω.

Wordclock I/Oworldclock Io-
2x Word Clock Inputs on 2x BNC connectors, accept standard word clock at 44.1, 48, 88.2, 96, 176.4 or 192kHz. The data rate can be the same as the clock rate or an exact multiple of the clock rate. Sensitive to TTL levels. Word Clock Output on 1x BNC connector. In Master mode, a TTL-compatible word clock appears on this output.

MQA- Full decoding and rendering of MQA data from the Network and USB2 inputs. Final rendering of unfolded MQA data only from the other inputs.

Residual Noise- 24-bit data: Better than –113dB0, 20Hz - 20kHz unweighted. (6V output setting)

L R Crosstalk- Better than -115dB0, 20Hz – 20kHz

Spurious Responses- Better than -105dB0, 20Hz – 20kHz

Filters- PCM mode: up to 6 filters give different trade-offs between the Nyquist image rejection and the phase response. DSD mode: 4 filters progressively reduce out-of-audio band noise level.

Conversions- DXD as standard or optional DSD upsampling

Software Updates- Download and update functionality available via Mosaic App

Local Control- dCS Mosaic app for unit configuration and playback. RS232 interface (controlled by a 3rd party automation system). dCS Universal IR remote control is available as an optional extra.
