multi-room feature (1 Viewer)

Hey, guys just a question for all the "gurus" in this forum. I'm wiring up my family room with in-wall speaker wires(CL3 rated, 12ga.)and I have an old HK325(5 ch) for my surround with a multi-room feature. I read some article saying that you need an amp to power this extra speakers? It didn't mention any need for an amp in the manual and I'm just adding a pair of outdoor speakers for this feature. Would it overwork the receiver if i don't add an amp? Appreciate the reply.

generally an extra pair is not a problem. small amps are pretty cheap and much safer than dividing up power
if used occasionally dont worry

Multi-room, multi-zone can be very confusing. A true multi-room receiver can play source A in the main room and play source B in another room at the same time. My Denon 3803 is a 7.1 receiver, so it lets you use 2 of the amps for Zone 2 while still playing 5.1 in the main room at the same time. Many cheaper receiver will either use the amps for the rear channels (meaning you do not get 5.1 in the main room), or do not have amps for zone 2 at all. In either of the last 2 cases you need a seperate amp to power zone 2.
Then, don't be confused with receivers that have A/B connections for the main speakers. They are usually meant to have only one pair of speakers running at a time, and have nothing to do with source B.
