Why does the amplifier left speaker go right and the right go left?


The Naim Supernait 3 integrated amplifier has a unique setup for its speaker terminals that may appear counterintuitive at first glance. When facing the amplifier, the speaker inputs are indeed arranged such that the left speaker cables need to be connected to the right side inputs and vice versa.

This means when facing the amplifier, the speaker cables are indeed connected in a manner that might appear reversed: the left speaker cables are connected to the right side inputs and vice versa. So users must ‘crisscross’ the cables to connect them correctly.

i was told “This setup is due to the specific design and layout of the amplifier’s rear panel, which includes various input and output connections, including proprietary DIN inputs and RCA jacks. The speaker terminals are located to the right of the power inlet and rocker switch, and they use Naim’s custom connectors designed to comply with EU safety regulations. This arrangement is part of Naim’s overall design philosophy to optimize performance and minimize mechanical noise, which includes careful isolation of components and specific wiring practices”.

This seems strange but this is the way it works. It is important to follow this setup to ensure proper sound channeling and performance. I wanted everyone to be aware.

Certainly the safety regulations in this case are strongly influenced by the highway code, as right-hand driving applies in the UK.

Assuming you plugged the left into the left +- and right into the right side, then who cares where they are on the rear panel?  

Does your Pre-Amp allow you to swap L/R? Mine does, would just wire them up crossed, and switch on the Pre.  Or just leave it alone, knowing it has a quirk. 

Another useless thing would be to just tun the amp upside down, then they would be the correct side.
