The US-1641 is a single-rackspace USB 2.0 Audio/MIDI interface packed with I/O: 16 inputs and four outputs can be used simultaneously, making it ideal for live performance recording.
The US-1641 has eight studio-quality microphone inputs with phantom power and level indicators, two line/instrument switchable inputs on the front, four additional balanced line inputs on the rear, four line-level outputs, digital SPDIF I/O (output switchable to AES/EBU), independent monitor and headphone outputs with separate level controls and 16 channels of MIDI I/O. It offers zero-latency hardware monitoring and sampling rates up to 96kHz at 24-bit resolution. Cubase LE4 and TASCAM’s own Continuous Velocity Piano are supplied as standard.
