Hi James, sorry for my late reply.Actually Nick, on closer inspection, unless I've misunderstood completely, looking at the spec of the PVA 7, I don't think it would increase the power output from what I'm already getting from the 720 running 5 channels?
Just wanted to say that I have had the pleasure of dealing with Nick before , he's a knowledgeable and honest guy, you can buy with confidence if you decide to proceed. Makes a great Coffee too.......Thajks Nick for your reply. Very much appreciated.
Oh I'm so tempted.....
Nick, what is the height of the amp?Hi James, sorry for my late reply.
Anthem only list the MRX 720 power into 2 channels, meaning that when you are driving 5 or 7 channels the output for each channel will be much less. To get an idea of the power difference look at the maximum power consumption of each unit, the 720 only pulls 485 watts, by time you take a bit of this off as lost power due to efficiency and the processing and other circuits, this doesn't leave a lot split across up to 7 channels. The PVA 7 can pull up to 1500 watts and there aren't any extra circuits.
How many speakers are you running? I've owned MRX 300, 510 and 720 and always preferred them with power amps, it's even more recommended if any of your speakers are 4 ohms.
Edit - I see from your other thread you are running 5 x XTZ cinema, these are 4 ohms, so the PVA 7 can drive 7 x 4 ohm speakers at 140w each, 7 x 140 = 980w, now take the 980w and split it into 5 channels, potentially 196w per channel, they state it will do 200w driving only 1 channel so it's probably not far off.
As above, 14.9 cm.Nick, what is the height of the amp?
