I have a NAD 3240PE amp which I havent used for a number of years but Im now bringing it back into service.
Im thinking of pairing it up with a pair of Mordaunt & Short Avant 902i speakers but Im unsure about the impedance setting for the amp.
The nominal impedance for the speakers is 4-8 ohms.
The amp has two impedance settings 4 ohm (NORMAL) and 8 ohm (HIGH)
The spec for the amp says the following:
All NAD amps are designed to produce maximum power output into impedances of 2 to 6 ohms at the 4 ohm (NORMAL) setting of the amps impedance selector.
If you are using a single pair of speakers whose true impedance is above 6 ohms at all frequencies, you can optimise the amp for maximum power delivery by re-setting the switch to 8 ohm.
CAUTION: If the impedance switch is set to 8 ohms with speakers whose true impedance is less than 6 ohms the amp may overheat and shut down when operated at high output levels.
So my instinct is to keep the amp impedance at 4 ohms and hope to receive universal agreement on this?
