The Next Generation of Simple, High Quality Audio Transfer
REAC (Roland Ethernet Audio Communication) is Roland’s original technology for low latency, high quality digital audio transfer. Products using REAC technology are installed today in many venues and have been used for high profile events worldwide. REAC’s 24-bit, 40x40 channel protocol delivers pristine digital audio via lightweight, inexpensive and easy to install cable (Cat5e).
