Receiver turns on and clicks off when volume is raised over 8 or 9 on the dial

Hi Markes,

It could be that there is a frayed speaker wire touching the back of the receiver and when playing at a low level the speakers do not require that much power, however when the level from the speakers increases more power is required and if there is a frayed speaker wire touching the back of the receiver there could be a short causing the receiver to shut down. A way to avoid the frayed wire is to use "Banana Connectors" that the speaker wires goes to and the connector will plug into the speaker posts. Please try the following to see where the issue is coming from. Have the receiver turned off, make sure all the speaker wires are labeled, and disconnect them from the speaker terminals. Turn the receiver on select a source that would give you sound if the speakers where still connected and turn the volume all the way up. If the receiver shuts down than it would need to go to a service center as it is an internal problem with it. If the receiver does not shut down, turn the volume down, shut the receiver off and connect one speaker and than turn the receiver on selecting the same source as before and raising the volume up. If the receiver shuts down, remove that speaker from the post and connect it to another speaker post to determine if it is the receiver or the speaker itself that is giving you the problem. If the receiver should shut down after moving that speaker you know it is a problem with the speaker or the wiring. If the receiver does not shut down, turn the volume down, shut the receiver off and connect another speaker followed by doing the previous test procedure. Keep adding speakers until you have them all reconnected to the receiver as long as it has not shut off while trying the test procedure. After determining whether it is the speakers or the receiver you would need to bring either to a service center to be repaired.

The system is overheating

the clicking may have been coming from the relay itself, but it doesn't simply mean that the relay is faulty. clicking may also be caused by transformers, indicating that some electronic components have developed SHORT CIRCUIT. try measuring resistance of transistors and diodes near the power unit (unplug/turn the unit OFF of course) check also for the impedance of the output power transformers.
check the amplifier IC for short also.

What speakers you have connected? This receiver supports only 6 and 8 ohm speakers (not 4 ohm). Also check if the ohm settings are correctly set in Advanced Setup (in standby press on the front panel STANDBY while holding STRAIGHT button). In this menu check the setting SP IMP. (speaker impedance) if it maches your speakers (6 or 8 ohm).
Disconnect all inputs and also all speakers. With nothing connected, try to increase the volume. If it still will power off, the unit is probably faulty and should be repaired.
If it does turn off only with speakers connected, check the speaker wires and the speakers, the problem will be there.

Onkyo receivers have a safety circuit in them to protect the Amplifier from blowing up:

If you listen closely when it shuts down ( after a loud scene ) there is likely a loud 'Relay Click'..
If this is what is happening you might be able to verify it by turning the volume all the way 'off' and waiting for the circuit ro reset ( releasing the safety relays & returning power to the internal Amplifier ) : you should hear another click, yhen you can bring the volume back up carefully and there will be sound again.

This safety circuit trips when then Onkyo receiver detects an 'Over Current' condition on the
' Power Supply ' that feeds the internal 'Audio Amplifier'..

Generally caused by:

1.
Improper load presented to the Amp outputs ( FL, LR, RL, RR, SUB, CENTER )
If you can ( one at a time ) turn off the SUB, Center, Fronts and Rears: trying to re-create the failure each time while you have one part of your system disabled or having their level turned way down..
You can isolate where the problem is coming from.

- any or all of these speakers being the wrong Impedence ( I.E. 4 Ohms instead of 8 Ohms )
Unless the receiver manual or the sticker near the 'speaker connetor' specifies a range or another value, you should assume 8 Ohms. Your speakers should say on the back of them.

- any of the speakers being connected in parallel ( 2 speakers to a single one speaker output ) .. Two 8 Ohm speakers connected in parallel make a 4 Ohm load to the amplifier.

- If the Suwoofer is Passive ( Not having its own power cord and amplifer ) it has a
Passive Crossover : this crossover can have its own power rating or limitation.. If it is constructed with capacitors that have too low of a working voltage, then they can saturate and the crossover itself can present a load to the amplifier that will case this 'Over Current Shut-Down'..


You user manual should detail this.

This is because the volume knob on ANY stereo is actually an attenuator.  Meaning, the stereo would play at full blast (way too loud!) if left to it's own limits of power, so your volume knob is actually "dialing down" the power, or when fully turned up, letting it all flow.
The reason that the numbers change like that is it's showing you how much attenuation is happening in decibels, or dB, so for insTance, when it's at "-30" that's a pretty decent volume, but at "-5" it's much louder and your neighbors might complain.  I think you'll notice that it can be cranked to something like "+5" which on my AVR 100 will blow the speakers.
In other words, this is normal, so relax and enjoy the music!

My SR605 gets extremely hot. This is especially true when both amplifiers are running together supporting 2 separate channels. I added a 2 way speaker selector from Russound that supports 2 sets of 8 ohm speakers on Zone 2 and the receiver shuts down at about 74 dcbs and gets very hot. Checked the jumpers on the selector and they are set at 8ohms.

Have returned the Russound selector to them and had it checked out. Appears to be fine. Even when Zone 2 is not in use the receiver gets extremely hot. It is in a wood cabinet wih glass doors but even with the door open the temperture is very hot. As the volume is raise the heat increases and the receive trips off.

Very unusual in my opinion. Is this normel for the receiver to heat up as the volume is increased.

you may be using an equalizer? try to pop-up the volume with all tone controls in flat mode. see if it still cuts off. if this is the first time youencounter this then something must be wroing with either your speakers or your amp. unless your ventilation is not good enoughg, you can also try placing a blower on top of your unit to cool it down
