The NAD C368 Hybrid Digital DAC was designed with all the crucial requirements. From low noise circuits to precise volume control action, to accurate channel balance and proper input and output impedance characteristics. Including a MM Phono stage with precisely accurate RIAA equalization, high overload margins, extremely low noise, and an innovative circuit to suppress infrasonic noise that is present on all LPs – all without affecting bass response. Line inputs can accommodate all kinds of analogue source components by offering ideal input impedance characteristics with linear ultra-low-noise buffer amplifiers to prevent any sonic degradation. Also included is separate headphone amplifier with low output impedance and very high output voltage capability – enough to drive even high impedance studio monitor headphones. Low impedance line outputs that can connect to subwoofers extend the versatility of this well thought out amplifier. 80W x 2 Continuous power into 8 or 4 Ohms Bluetooth A2DP with aptX supported MM Phono input Analogue line inputs SPDIF coax and optical inputs Speaker A, Speaker B Stereo or Bridge mode configuration Preamp/Subwoofer out Headphone amplifier MDC Slots for future upgrades IR Remote Smartphone Control App 12V Trigger in/out IR in/out RS-232 Serial port for control Control4, Crestron, RTI, URC, AMX, Savant, Elan certified
