The DSP Mixer Has Two Operational Modes Designed for Music Creation and Podcasting On-Board Digital Mixer (DSP Mixer) for Easy, Convenient Professional Recording In addition, INPUT-1 can connect any high-impedance equipment directly, like a guitar. Having both options for condenser mics and line level inputs ensures you are getting the best possible sound and lowest-noise when recording. The US-322 and the US-366 are designed with two XLR with +48V phantom power and two TRS inputs. Two XLR/TRS (MIC/LINE) Inputs with Full +48V Phantom Power Supply (Included CUBASE LE can not record by 192kHz) The US-322 and the US-366 are suited perfectly for these high-quality minded recordings. In the process of creating music, many engineers have started utilizing high-resolution formats while recording to ensure the best quality sounds. US-366: Up to 192kHz/24bit Recording – US-322:Up to 96kHz/24bit Recording Manufactured with a discrete structure and select premium parts, the HDDA pre-amp achieves wider frequency response (10Hz to 68kHz), high S/N ratio, low noise and low THD+N. To ensure superior sound, TASCAM organized months of tests and trials to design the HDDA mic pre-amplifier.
