I want to use my Crown XLS 1000 to power my Cerwin Vega Sub for use in my home theater setup. I have a Yamaha RX-V673 so I sent an email to the Yamaha Customer Support Team and their response was:
"The subwoofer output is rated at
SUBWOOFER (2ch Stereo, Front: Small) .................1 V/1.2 k?
Your amplifier would have to support that for inputs. "
I then sent an email to Crown Audio and their response was:
"It will work but you won’t get the amp to full rated output. The XLS has a 1.4V input sensitivity so the 1v output of the Yamaha won’t drive the amp to full output. You can get a Rolls MB15b which can take that output level to a +4dBu level which will drive the amp to full rate."
Anyone here have any experience with either the Rolls MB15b or the ART Cleanbox Pro? Any advantages/disadvantages I should be aware of or am I good either way?
