MIT Music and Theater Arts: MObile Sound System (MOSS)

The MObile Sound System (MOSS) is essentially a professional recording studio without a room. It consists of two road cases on casters: one is for storing a laptop computer, audio equipment, and the patching interface, and the other is for storing microphones, headphones, microphone stands, speaker stands, power strips, cables and a snake.

This system can record, mix, or process 16 analog inputs and provide 16 analog outputs, all at 24 bit/96 kHz. The laptop currently runs Logic Studio, Peak, and Max/MSP. 16 channels of high quality preamps are provided (8 channels of True Precision, 4 channels of full channel-strip functionality with EQ and compression, and two different types of high-quality two-channel preamps). The system can record up to 16 channels to the computer, and simultaneously or independently record 2 channels to a flash-based recorder. For overdubs, remote recording, or sending click tracks, 8-channel monitor mixes can be sent over CAT-5 cable to any of four personal mixing units. All I/O is available via front-mounted patch bays and panels, making custom setups as fast and convenient as possible.

The setup includes 6 small diaphragm cardioid microphones (AT4041), 4 large diaphragm multi-pattern microphones (AKG-414), 4 dynamic microphones (2 SM57, 2 MD421), 1 ribbon (Royer R-101), 1 large diaphragm tube mic (Mojave MA200), 2 omnidirectional microphones (Earthworks TC20mp), and 8 stereo direct boxes. There are 16 microphones stands, a 16 channel, 100 foot snake, and plenty of microphone cables. For output, the setup includes 8 Yamaha MSR100s, 4 speaker stands, and a Mackie HD1501 600W powered sub.

Applications include recording in small and large spaces, with or without overdubs; multi-channel sound reinforcement and sound installations; interactive audio works and performances requiring a computer and audio I/O; and teaching recording techniques or providing sound reinforcement for a live-electronics ensemble of up to 16 performers.

This system was designed and installed by Christopher Ariza, in the capacity of Visiting Assistant Professor of Music at MIT.
