The Massive Audio UW-1 universal RCA adapter is used to activate the ATO (auto turn on) feature in all Blade, Blade BP, Edge, Nano BLU, Nano BLU-M Marine and the DBX4 amplifiers.
Each UW-1 has two male RCA plugs with short high grade braided cables that are pre-stripped to form bare (+) & (-) connections. These bare wires then can be attached to any O.E.M. speaker outputs from a factory radio and plugged into any of the amps listed above. They will take any factory speaker outputs up to 10V and can be inserted into the amps RCA inputs. This will activate the ATO feature by sensing the radios DC Off Set eliminating the need for a 12V turn on lead. The 12V turn on lead is converted into a switched 12V out to turn on any additional products.
