Hi I have a sony AV Amp and I have Monitor Audio Silver Line 5i Floor Standers which are a great speaker.

Anyhow, just won on Ebay a Monitor Audio 10i Centre speaker in the same finish as my speakers and it arrived today,

hooked it up and sounded perfect then my Amp cut the centre speaker channel off. Would not work even through test tones. I checked the speaker on another channel and worked fine.

Now I have hit the AMP and it all is working fine.

My AV Sony amp is some 5 years old but 'touch wood' works fine till now. What could be the problem regarding the centre channel? could it be a relay as I hear a click every now and then and then the centre channel cuts out.

Just wondering as never used the centre channel before.

I may change the amp sometime soon but I have always been happy with it. Plus it has great connections for me (x3 optical in's)

Perhaps someone can shed some light on it. Is it worth taking the case apart and blowing any dust out that is in there from over the years or what ?
 
It COULD be current caused. Some amps have protection modes, when too much current is drawn either the channel/amp is switched off. Double check what ohm the speaker is and see if your amp has a minimum ohm etc setting. If your new speaker is causing the draw of the system to overload the PSU of the amp this could also cause it, so when you test it on another output you're only using 4 speakers again, and the draw drops, so the protection circuits dont kick in.

Shot in the dark but could be the cause :)
 
Looking in the AMP manual:

Front speakers 8 or 4 ohms

surround and centre 8 ohms

My amp has a switch on the back for the front speakers
Impedance selector-
between 4 & 8 ohms = 4 ohms switch
8 ohms or higher = 8ohms switch

My speakers are I would have thought all 8 ohms? isnt that the norm?


mmmm confused. Maybe I should phone monitor audio (uk) in the morning to confirm why this could be happening.

My amp should easily be able to cope though. The spec in the manual says:

Front: 100 W + 100W
Center: 100W
surround 100W + 100W
