Loading the Yamaha CR-820
I have acquired a fully functional Yamaha CR-820 and would like to use it in my bar.
I have 4 8 Ohm speakers in the bar and would like to place two additional 6 Ohm speakers to cover the outside terrace. Currently I can't invest in a new pair of speakers so I would like to use what I have.
I was thinking of connecting the 4 internal 8 Ohm speakers 2 and 2 together in series so I can drive them with two channels. For inside that will be sufficient I believe since I only play background music. The other two channels I would like to use for outside because I will need a bit more volume. Since the amp. can only work in 8-16Ohm range I cant connect the two outside 6 ohm speakers each to his own channel, but will have to connect them in series to get 12 ohm. That leaves one channel open.
My question is if I can leave one channel open without causing any damage to the amp?
In the future I will definitely get a pair of 8ohms for the outside but for now i have to live with what I have.
Thanks for help!
