1 Question & 1 Answer
from CA asked:
September 6, 2016
The description of bridging is not clear. I want to connect two 75W amplifier outputs (Left and Right) to this uni so it outputs a mono 70V signal. How is this done and what is the power output?
1 Answer
Hi Kim: Based upon the Owner's Manual it us telling us that you need a bridged input in order to use a Constant Voltage 70V/100V mono operation. So if your Amplifier does not have a bridged mode like our AMP120, AMP200 and AMP300 this unit will not work for your application. I agree with you it is confusing. I personally do not recommend this unit. TL/4056
