Yes thats correct; • Use M+ and M- for the output in MONO mode.Hi Guys,
is there any way to connect the AHB2 in bridge mono mode ,without using the Speakon connector ?
The 2 "red" outputs marked as m+ and m- which is not clear to me.
thanks

Thank you very much for your response.Yes thats correct; • Use M+ and M- for the output in MONO mode.
Snce you have 2 AHB2, I would suggest you try to biamp the F208 too, instead of bridge mono.
Not saying which one is better, just test it out yourself which one you like more.
I myself like biamp more than bridge.
I have 3 AHB2 , for LCR.
How much lower will the damping be to go from biamp > normal stereo > bridged mono using the Revel F208 as an example?
A newbie here so be kind…. Would it make any sense to run my gustard x16 into my Chinese clone tube preamp and then into the benchmark, the tube pre amp only has rca input ant output. Thanks, Some people say there is no pre amp like NO pre amp.
Ah, that’s what I was thinking but wasn’t sure about biamping being better than stereo.Damping factor is DF = Zload/Zamp so for bi-amping Zamp (amplifier output impedance) does not change from normal stereo. In bridged mode you are using both amp channels in series (out of phase) so effectively output impedance is doubled and thus damping factor is halved: DF = Zload/(2Zamp).

Maybe that’s why biamping might be better if you don’t need the power that bridged gives ?
Very true, never tried it but was speaking of this particular amp for two member’s comments on the two options and possible reason for their differences.Maybe, but that's a rabbit hole I don't feel like heading down... It depends upon the speaker's impedance, amplifier's output impedance (both of which vary over frequency), and your perception as frequency response and other parameters change. There is also the (valid) argument that bi-amping (even "AVR passive") isolates the upper and lower drivers so they do not modulate each other through the wires and amplifier's output impedance, but again I remain skeptical. Some of done it and reported benefits in blind testing so I suppose it is possible. I am too cheap and lazy.
I have bi-amped my system in the past, using an active or passive crossover network before the power amps, but for the past few years have not felt it worth the effort. I am not a believer in "passive bi-amping" as implemented by an AVR; there are theoretical advantages, but in practice I suspect it is inaudible. By and large my choice the past few years (10 or 20, who counts anymore? ) has been to get a single amplifier big enough to do the job and be done with it. We are long past the days when 10 or 20 W was typical and a 100-W amp a rare and expensive thing...

I know it as Damping factor as drilled into me by Crown amps in the mid 70's, but I suspect the question ought to be if by going bridged, what's the output impedance then (I did work it out from the Stereophile measurements and apart from a potential half a dB change over 10khz which many of us oldies can barely hear these days? the rest of the range isn't an issue at all really).Damping factor will be cut in half when bridged, but it doesn't matter.
Output impedance doubles when bridged as you now have two amps in series with the speaker terminals. Damping factor = Zspeaker/Zamp.I know it as Damping factor as drilled into me by Crown amps in the mid 70's, but I suspect the question ought to be if by going bridged, what's the output impedance then (I did work it out from the Stereophile measurements and apart from a potential half a dB change over 10khz which many of us oldies can barely hear these days? the rest of the range isn't an issue at all really).
