Multi-Channel Digital Audio Transfer Systems
Roland’s original Ethernet technology •REAC, based on the Ethernet 100BASE-TX protocol, transfers signals using Cat5e cable. •Durable and reliable connector made by Neutrik •Up to 40 channels of 24bit/96kHz audio plus MIDI and remote control data can be transferred in one cable. REAC (Roland Ethernet Audio Communication) is newly designed technology for digital audio transfer by Roland.
REAC terminals S-4000 Digital Snake System Input Channel Indicator This indicates Signal, Clip and On/Off status of the phantom power for each input channel. The status of the input channels can be checked even from the stage. Analog Input Modules On board 24bit/96kHz AD converters and high quality mic pre-amps with phantom power supply. Analog Output Modules On board 24bit/96kHz DA converters.

“The fact that there is no noise when I turn the snake on is a vast improvement over previous years. No hums, buzzes or clicks, which means one less place to look when I am trouble shooting,” Jon Laterza, Freelance Audio Engineer, Lincoln Center Out of Doors Festival, NY “The sonic quality and clarity of the digital snake is awesome, I feel and hear the dynamics of the sound clearer than any analog snake. Plus it’s extremely easy to move for touring.
