Hi All,
I know this is a very basic question.
We connect speakers with different impedences to AVRs like 1600h, 2700h.
Do we have an option to select the impedence in these AVRs or output is automatically adjusted accordingly.
Thanks in advance for the help...
Some AVRs have impedance switches, but we do not suggest using them. The switch should be left to the highest impedance setting, no matter the nominal impedance of the speaker to be connected.
Here is a link explaining the reason for the recommendation which differs from that of the manufacturers:
This article explores the purpose and function of the impedance switch found on some A/V receivers. Tradeoffs of following manufacturers recommended settings are also discussed. YouTube video inside.

Basically, solid state amplifiers don't need impedance selection settings, as their output stage adapts to the various impedance loads presented by a loudspeaker. The impedance of any speaker varies with frequency, and the nominal impedance published by loudspeaker manufacturers is not always accurate.
