sir good morning i just want to ask something regarding your amplifier model PRS-4B125 @ the back side of the amplier the output is written speaker A and B it should be both use or onr line only?
Dear Joel, the PRS-4B125 is a 4 channel amplifier, each channel with an A and a B 100V output. Both outputs are connected to the same amplifier channel so both outputs have the same audio signal. You can use one of the output channels or both or connect the speaker line as a loop between A and B, Class-A speaker line wiring. You can also use End of Line supervision on the speaker lines. Everything can be configured in the configuration of the Praesideo system. Check the manual for more information. The manual can be downloaded from the Bosch product web page. If you need further information please contact our local sales team: www.boschsecurity.com/xc/en/contact/ Thank you
Nice
