dCS Scarlatti DAC User Manual Software Issue 1.2xAugust 2011Flename: Scarlatti DAC Manual v1_2x.docx Page 23 English versionSPECIFICATIONConverter type 5-bit, 2.822 or 3.07MS/s oversampled, dCS Ring DAC topology.Digital inputs IEEE 1394 interface on 2x 6-way connectors. The interface accepts dCS-encrypted DSD (1 bit data at 2.822MS/s) from up to 4 sources.2x AES/EBU on 3-pin female XLR connectors. Each will accept up to 24 bitPCM at 32 - 192kS/s, OR as a Dual AES pair at 88.2, 96, 176.4 or 192kS/s.3x SPDIF on 2x RCA Phono and 1x BNC connectors. Each will accept up to24 bit PCM at 32 - 192kS/s.1x SPDIF optical on a Toslink connector, will accept up to 24 bit PCM at 32 -96kS/s.1x SDIF-2 interface on 2x BNC connectors, will accept up to 24 bit PCM at32 - 96kS/s or SDIF-2 DSD (auto-selected). If the unit is not in Master mode,this interface requires a compatible word clock input, locked to the data rate.Clocking Word Clock Input on 1x BNC connector, accepts standard word clock at 32,44.1, 48, 88.2, 96, 176.4 or 192kHz. The data rate can be the same as theclock rate or an exact multiple (0.25x, 0.5x, 1x, 2x, 4x) of the clock rate.Sensitive to TTL levels.Word Clock Output on 1x BNC connector. In Master mode, a TTL-compatible44.1kHz word clock appears on this output, not temperature compensated.Frequency response(set to Filter 1)Fs = 32kS/sFs = 44.1 or 48kS/sFs = 88.2 or 96kS/sFs = 176.4 or 192kS/sDSD+0.1/-0.5dB, 10Hz to 15kHz+/-0.1dB, 10Hz to 20kHz+/-0.1dB, 10Hz to 20kHz+/-0.1dB, 10Hz to 20kHz+/-0.1dB, 10Hz to 20kHz-3dB @ >38kHz-3dB @ >67kHz-3dB @ >66kHzResidual noise Better than –110dB0, 20Hz - 20kHz unweighted.Spurious responses Better than –100dB0, 20Hz - 20kHz.L-R crosstalk Better than –80dB0, 20Hz - 20kHz.Output levels 2V rms or 6V rms on all outputs for a full-scale input, set in the menu.Balanced outputs 1 stereo pair on 2x 3-pin male XLR connectors (pin 2 = hot, pin 3 = cold).These outputs are electronically balanced and floating, the signal balanceratio at 1kHz is better than 40dB. Output impedance is 3Ω, maximum load is600Ω (a 10kΩ - 100kΩ load is recommended).Unbalanced outputs 1 stereo pair on 2x RCA Phono connectors. Output impedance is 52Ω,maximum load is 600Ω (a 10kΩ - 100kΩ load is recommended).Size and weight 465mm (18.3”) long x 405mm (16.0”) deep x 75mm (3.0”) high. Allow extradepth for cable connectors. Allow space for air flow around the unit. Weight:11.3kg (24.9lbs).Power requirements Internally set to either 100, 115/120, 220 or 230/240V AC, 49 – 62Hz.Power consumption: 22W typical, 30W maximum.These specifications are subject to change without notice.
