bridging integrated amplifier


Hi, I have a NAD 7220PE. Would it be safe to wire the the left and right channels to bridge to a single 8ohm speaker?
Thanks!

If you want both channels output through a single speaker rated at 8 ohms, you could just connect it conventionally via one set of speaer terminals, then set NAD's speaker impedance selector to 8 ohms, and then press the "Mono" selector button on the front right panel of the receiver, to merge stereo signals into a single mono output.
Do you actually need to double the power output, anyway?

Doing this will let the receiver sort of act as a 8 ohm monoblock amp from the way I view the schematic. I don't see it as acting a bridged amp.
Thanks for all the input, I'm following Sandstone's advice. My setup is for my home office and I have limited desk space. I run 2 small speakers next to each other, but I have single large bookshelf that can take up the same space and would give me more low end. I was looking to take advantage of the power options from the stereo but rather not risk off wiring.

Make sure the speaker is rated at 8 ohms for the 8 ohm setting. If it is a 4 ohm speaker, use the 4 ohm setting. Otherwise, the one channel it's running on can overheat and get damaged. Using the mono setting will make sure you hear both left and right channels, through the single speaker.
Rome,
One additional thought - if your single speaker is able to be biwired - that is, has separate sets of connectors for low-frequency and high-frequency ranges, you should actually be able to connect both "channels" of your receiver while in mono mode. Remove the speaker's jumpers and then conventionally connect "left channel" outputs to one set of terminals and then "right channel" outputs to the other. Both channels would actually be outputting in mono mode. Not sure whether this will actually deliver more power or better dynamics but it may be worth a try.
Best,
