ZA3 as mono amp for center speaker?

[Papawolf]

Hi, I'd like to use a ZA 3 to power my home theater center speaker only. Center speakers are single-channel in.

Is this the procedure?
-single RCA male to double RCA male (pre-out from the AVR to both ZA 3 RCAs in)
-spkr cables from both right channel spkr outs on ZA3 to the spkr. inputs on my center channel
-switch ZA3 from stereo to mono mode

Thanks in advance.
