SM PRO AUDIO ADDA-192S Deadstock Unopened, brand new, so all units are sold out. Extremely cheap for a high-end ADDA. This is an interesting ADDA that uses AD/DA ICs found in LYNX Studio's high-end AD/DA converters. It also features a high-end chip from the now-defunct (sadly acquired) Vectron company for its clock. For the 2-channel input with 48V phantom power preamp, (depending on microphone capacity) there can be variations in the boost power, so personally I recommend phantom power off or line level, but it functions sufficiently as an AD. It has analog and digital input level adjustment and mixing functions, making it quite versatile as a direct monitor. 24-Bit AD / DA Sampling Rates: 44.1, 48, 96 & 192 kHz Equipped with -20 dB PAD Internal and external synchronization possible Outputs are for both Balanced / Unbalanced Built-in headphone amplifier #RME #MOTU #UAD
