Unfortunately not, because I struggled to get my speakers for ages so I had the receiver sat there for ages. I will just have to contact the company I bought it from. I won't wait for repair times, I should be able to get them to send a new one out as this is in perfect condition apart from the fact that it doesn't work for whatever reason. I don't feel like I should suffer because they sold me faulty goods. I will have to wait until monday, which means no music or sound without headphones for the duration of the weekend.
Thanks for your help.
While i'm here, are the receiver and speakers are compatible? I did some research but I'm not really all that confident with this stuff.
If it's not I can look for a more compatible one. More Watts or Less Watts, whichever is required.
Unfortunately you have wound up on the rocks of physics, because of what the specs don't tell you.
We have covered this ground often, in that a speaker manufacturer's claim of what the speaker's impedance is, is of no guide to the suitability of associated equipment what ever.
This is a classic case of nominal impedance meaning nothing.
Here is the impedance curves and the phase angles between voltage and current with frequency, of your speakers.
Now as you can see the impedance dips to 3.6 ohms at 190 Hz.
Now the speakers are below six ohms in a good deal of the frequency range where the bulk of the power is consumed.
Now it gets worse, when we consider the phase angles, which are in negative territory at times. For instance the graph shows an impedance of 5 ohms at 110 Hz, but when you do the calculations to factor in the phase angle of -45 degrees, the amplifier sees an impedance of 3.5 ohms.
As the reviewer point out these speakers require four ohm capable amplification.
Now the sensitivity is quoted as 86 db 2.83 volts 1 meter. However because of the impedance and phase angles the speakers are actually 3 db less sensitive than they appear.
This is a frequent problem.
These speakers are well reviewed as giving good performance per dollar, and they have a very good bass response for a bookshelf. It is this latter that is largely responsible for the difficult load.
The problem is that these are budget speakers, but not suitable for budget receivers. A lot of this is due to the fact that HT is big in the UK, two channel stereo music systems still rule. British integrated amps also still rule. While these devices are not usually very high powered, they are reliable and stable under just about all loads.
Because your receiver tells you there is a speaker error where there is not, I can guarantee that the short circuit is in the power transistors of at least one channel.
Unfortunately I suspect that you will encounter this problem again with a replacement receiver.
Onkyo are far from the most robust, especially at the lower end of their price range.
You need to find a four ohm capable receiver, or get one with pre outs and use external amplification.
The real problem is that amplifiers belong in the speakers, NOT the receiver. All cars audio systems work like this in newer offerings.
The car industry have poured millions and millions of R & D dollars into this, especially Audi. My year old Chevy, has DSP crossover and amps for every frequency range. This is the stock system. It sounds wonderful, and far better than most domestic audio systems, even expensive ones.
The long term answer, to your frequently encountered problem, is keeping the signal digital right from the microphone capsules to loudspeaker drivers, with the new AES standard optical interconnects, so we end ground loop problems for ever.
The big money is now determined that technology, now largely in cars, is brought to home audio. The big money is now on it and determined to bring it about. The sooner the better.
The current way of doing things is now way out of date. Going forward promises a quantum leap in performance per dollar, reliability and and end to compatibility problems.
