Preamplifier function: D30Pro has preamplifier function so you can control the output volume on the front panel and also at the remote control. Since it's noise is <0.9uVrms@SE out and <1. 1uVrms@BAL out which is significantly lower than other similar products it is very suitable for connecting to power amplifiers or monitor speakers. And this will also help you leave the budget of a preamplifier. 2. CPLD focusing on clock processing and digital signal optimization restoring what the digital signal should be.3. We use up to 8 independent LDOs to supply power to different loads SO there is no longer interference between different loads.4. Both R and XLR have reached the 1 20dB SINAD So that R transmission can also have same excellent performance as XLR.5.A30Pro will be the best partner for D30Pro: 2x6W@ 1 6ohm 2x5.5W@32ohm2x840mW @300ohmso there is no headphone that A30Pro can't drive well. New specifically redesigned NF module provide THD+N<0 .00006% and <0.3uV noise.Spec:USB IN: PCM 44. 1 kHz-384kHz/16bit-32bitDSD DSD64-DSD256 (Native)¡¢DSD64-DSD128 (Dop)COAX/OPT IN: PCM 44. 1 kHz-192kHz/16bit-24bitDSD DSD64(Dop)D30 pro Decoding parameters (USB In@96kHz)LINE OUT R:THD+N@A-wt: <0.0001%@1kHzTHD@No-wt 45kBw: <0.0004%@20-20kHzSNR@A-wt: 127dB@1kHzDynamic range@A-wt: 127dB @1kHzFrequency Response:20Hz-20kHz(+0.1dB)20Hz-40kHz(+0.3dB)Output Voltage: 2Vrms@0dBFSNoise @A-wt: < 0.9uVrmsCrosstalk: -116dB@1kHzOutput Impedance: 20¦¸LINE OUT XLR:THD+N@A-wt: <0.00009% @1kHzTHD@No-wt 45kBw: <0.0004 % @20-20kHzSNR@A-wt: 132dB@1kHzDynamic range@A-wt: 132dB@1kHzFrequency Response:20Hz-20kHz(+0.1dB)20Hz-40kHz(+0.3dB)Output Voltage: 4Vrms@0dBFSNoise @A-wt: < 1.1uVrmsCrosstalk: -145dB@1kHzOutput Impedance: 40¦¸Topping A30Pro NF Headphone Amplifier AMPFeatures:->Audio by-pass even when power off.>Hi-res certified.>Fully balanced architecture.>Balanced XLR input support.>4-pin XLR+4.4mm Balanced output.>6.35mm SE output.>Three level gain(-14dB 0dB 14dB).>Ultra-Low Distortion(<0.00006%).>Ultra-Low Noise(<0.3uVrms).>Incredibly Powerful(Up to 6W output power @ 16ohms).Topping A30 Pro is an incredibly powerful desktop headphone amplifier with fully balanced 4-pin XLR and 4.4mm headphone output ports.
