In its simplest form, the M33 BluOS™ enabled DAC/amplifier is an ultra-high-performance streaming amplifier with superb audiophile sound. As a BluOS enabled component, the M33 can be combined with other players in a BluOS ecosystem of wirelessly networked music players throughout the home for an outstanding whole-home audio system. With the employment of the new Purifi Eigentakt™ Hybrid Digital amplifier technology, the M33 follows NAD’s long-standing tradition in identifying and developing cutting-edge amplification technology. With a minimum of 200W per channel on tap, the result is lifelike performance, exemplified by ultra-low distortion and noise.AMPLIFIER SECTIONRated output power (ref. 20 Hz-20 kHz at rated THD, both channels driven)200 W into 8 ohms 380 W into 4 ohmsRated output power, Bridge mode (ref. 20 Hz – 20 kHz at rated THD)700 W into 8 ohmsInput sensitivity865 mV (ref. 200W 8 ohms, Volume maximum)THD (20 Hz – 20 kHz)0.003 % (1W to 200 W, 8 ohms and 4 ohms)Signal-to-Noise ratio98 dB (A-weighted, ref. 1 W out in 8 ohms)120 dB (A-weighted, ref. 200 W out in 8 ohms)Clipping power210 W (0.1 % THD 1 kHz 8 ohms)IHF dynamic power8 ohms: 260 W4 ohms: 520 WPeak output current≥25 A (in 1 ohm, 1 ms)Damping factor800 (ref. 8 ohms, 20 Hz to 6.5 kHz)Frequency response±0.2 dB (20 Hz -20 kHz)-3 dB at 60 kHzPREAMPLIFIER SPECIFICATIONSLINE INInput Impedance (r and c)47kΩ/180pFInput Sensitivity280mV (ref. 500mV out, Volume Maximum)Maximum input level 20Hz-20Khz2 Vrms/8 Vrms (low sensitivity mode)Tone ControlsTreble: ±10dB at 10kHz Bass: ±10dB at 100HzMax Output Signal4Vrms (ref. 0.1% THD)PREOUTMaximum output level3.9 Vrms (ref. 0.1% THD)Signal-to-Noise ratio120 dB (A-weighted, ref. 2 V out)Output impedance100 ohmsSUBOUTMaximum output level1.1 Vrms (ref. 0.1 % THD 100Hz)Signal-to-Noise ratio102 dB (20 Hz-20 kHz, ref. 1V out)THD+N0.005 % (refer 1.1 V 20 Hz-200 Hz)Output impedance680 ohmsPHONOInput sensitivityMM: 1.2 mVMC: 100 µVInput impedance (R and C)MM: 56 kohms/100 pFMC: 100 ohms/280 pFSignal to noise ratio (ref. 2 V Preout A-weighted)MM: 92 dBMC: 76 dBTHD+N (ref 2V Preout 1kHz)MM: 0.003 %MC: 0.02 %RIAA response accuracy MM/MC±0.2 dB 20 Hz -20 kHzHEADPHONESOutput Impedance2.2ohmsOutput power100 mW/32 ohmsBluOS SECTIONAUDIOSupported audio file format*MP3, AAC, WMA, OGG, WMA-L, ALAC, OPUSSupported high- resolution audio file format*FLAC, MQA, WAV, AIFFSampling rateup to 192 kHzBit depths16 – 24CONNECTIVITYNetwork connectivity
