In the C 3050 Stereophonic Amplifier, NAD’s 50-year history of innovation meets the future of hi-fi. With its dual VU meters, push-button input selectors, walnut-finished vinyl-clad cabinet, and 1970s cursive-style branding, the C 3050 recalls the components that helped a generation of music-lovers discover the joys of great audio. With its 100-watt-per-channel HybridDigital UcD amplifier and Texas Instruments high-resolution differential DAC, the C 3050 delivers sound that will thrill today’s discerning listeners. And thanks to NAD’s MDC2 future-proofing technology, C 3050 owners can add leading-edge capabilities like BluOS high-resolution multi-room streaming and Dirac Live room correction.Retro design elements include satin walnut case, front-panel VU meters, push-button input controls, 1970s cursive branding, and dark grey front panelHybridDigital UcD AmplifierContinuous Power: 100 Watts per channel into 8/4 ohmsInstantaneous Power: 135 Watts per channelVanishingly low harmonic and intermodulation distortionMDC2 port for expanded functionalityPre-installed MDC2 BluOS-D module adds BluOS Hi-Res multi-room music streaming and Dirac Live room correctionMDC2 BluOS-D module provides access to more than 20 streaming services, including several that offer lossless and high-resolution audioSupport for Apple AirPlay 2, Spotify Connect, and Tidal ConnectVoice control via Amazon Alexa, Google Assistant, or Apple SiriHigh-performance 32-bit/384kHz Texas Instruments differential DACUltra-low-noise MM phono stage with infrasonic filtering circuitryOne optical, one coaxial digital inputHDMI-eARC inputOne set of line-level analogue inputs with low-noise buffer amplifiersSpeaker A/Speaker B outputsTwo-way Qualcomm aptX HD BluetoothSubwoofer outputDedicated headphone amplifierSupplied accessories include an IR remote control and a calibrated microphone for Dirac Live setupCI-Friendly – IR remote, 12V Trigger out, IR inSeamless integrations with smarthome control systems such as Control4, Crestron, RTI, URC, Push, Lutron, iPort, and ElanSpecificationsLINE INPUT, PRE-OUT (Analog bypass on)THD (20 Hz – 20 kHz):Signal-to-Noise Ratio: >95 dB (IHF; A-weighted, ref. 500 mV out, unity gain)Channel separation: >100 dB (1 kHz), >90 dB (10 kHz)Input impedance (R and C): 28 kohms + 360 pFMaximum input signal: >4.5 Vrms (ref. 0.1 % THD)Output impedance: 440 ohmsInput sensitivity: 270 mV (ref. 500 mV out, Volume maximum)Frequency response: ±0.3 dB (20 Hz – 20 kHz)Maximum voltage output -IHF load: >2 V (ref. 0.1 % THD)PHONO INPUT, PRE-OUT (Analog bypass on)THD (20 Hz – 20 kHz): <0.03% at 2 V outSignal-to-Noise Ratio: >79 dB (200 ohms source; A-weighted, ref. 500 mV out)Input Impedance (R and C): 46 kohms/100 pFInput sensitivity: 5.5 mV (ref. 500 mV out, Volume maximum)Frequency response: ±0.3 dB (20 Hz – 20 kHz)Maximum input signal at 1kHz: >80 mVrms (ref. 0.1 % THD)LINE INPUT, HEADPHONE OUT (Analog bypass on)THD (20 Hz – 20 kHz): <0.005% at 1V outSignal-to-Noise Ratio: >96 dB (32 ohms loads; A-WTD, ref. 2 V out, unity gainFrequency response: ±0.3 dB (20 Hz – 20 kHz)Channel separation: >60 dB at 1kHzOutput impedance: Output impedanceBluOS AUDIOSupported audio file format: MP3, AAC, WMA, OGG, WMA-L, ALAC, OPUSSupported high- resolution audio file format: FLAC, MQA, WAV, AIFFSampling rate: up to 192 kHzBit depths: 16 – 24BluOS SUPPORTED SERVICES***Integration partners: Control4, Crestron, ELAN, Lutron, Push, Roon, RTI, URCVoice Control: Skills and support for Amazon Alexa, Google Assistant and Apple’s Siri with corresponding enabled devices and AppBluOS CONNECTIVITYNetwork connectivity: Gigabit Ethernet RJ45, Wi-Fi 5Supported network file share protocol: Server Message Block (SMB)USB: 1 x Type-A port for connection to USB memory stick (FAT32 or NTFS formatted) and supported peripheralsBluetooth quality: aptX HD 5.0Bluetooth connectivity: Two-Way (Receive and Headphone modes)USER INTERFACESupported operating system: Music playback from network shares on the following desktop operating systems: Microsoft Windows XP, 2000, Vista, 7, 8 to current Windows Operating Systems and macOS versionsMobile Application: Free BluOS Controller App available for download from the respective App stores of Apple iOS devices (iPad, iPhone and iPod), Android devices, Kindle Fire andWindows or macOS desktopsMAIN IN, SPEAKER OUTContinuous output power into 8 ohms and 4 ohms: 100W (ref. 20 Hz-20 kHz at rated THD, both channels driven)THD (20 Hz – 20 kHz): <0.03% (250 mW to 100 W, 8 ohms and 4 ohms)Signal-to-Noise Ratio: >95dB (A-weighted, 500 mV input, ref. 1 W out in 8 ohms)Clipping power: >115 W (at 1 kHz 0.1 % THD)IHF dynamic power: 8 ohms: 180 W, 4 ohms: 250W, 2 ohms: 300 WPeak output current: >20A (in 1 ohm, 1 ms)Frequency response: ±0.3 dB (20 Hz – 20 kHz)Channel separation: >75dB (1 kHz), >70dB (10 kHz)Input sensitivity (for 100 W in 8 ohms): 540 mV, Digital: -6dBFSPower consumption – at Auto Standby ON and Network Standby OFF: 0.5 W*Power consumption – at Auto Standby ON and Network Standby ON: 2.0 W**Power consumption – OFF mode (Power switched OFF): 0.1 WFrequency band: 2.402G- 2.480GDIMENSION AND WEIGHTGross dimensions (W x H x D) ****: 435 x 110 x 355mm17 1/4 x 4 3/8 x 14 inchesNet weight: 10 kg (22 lbs)Shipping weight: 12.6 kg (27.8 lbs)
