My Sony STRDH590 went into protect mode after 30 min of listening

[sgtkahuna]

It's very hot, is this normal? it went into protect mode and shut off itself.

Vol was 60 ish, It's running two Monolith Encore T6's

Anytime a receiver goes into protection mode when operating is not "normal". I think the issue is the Encores are a nominal 4 ohm speakers, and the receiver isn't rated to drive anything lower than a nominal 6 ohms.

See the Sony STRDH590 Specs

Low volume levels probably will be okay, but if you want to get really loud, that will cause trouble.

I touched it and it was super hot, I'll try to attach some fans to it and see if it doesn't go into protect mode, is there any fan configuration recomendation?

You are going to have to face facts. You are not going to drive those speakers with that receiver, unless you play it VERY quietly. Those speakers need a top end receiver, or better a receiver with preouts and an external power amp. That receiver will have a very short life span driving those speakers unless you are very cautious indeed with the volume control. A fan is only a partial answer, as the current is just too high for the output devices driving those speakers.

Your best bet, it to put that receiver up for sale before it is ruined and worthless, and then purchase something more appropriate to drive those speakers.

Be warned the next time it goes into protection may be very well be the last time you hear from it. Heat kills output devices and fast.

What receiver can I get for these speakers?

What receiver can I get for these speakers?

I think that depends on what facilities you want. Four ohm capable receivers tend to be at the upper end and likely have a lot of facilities you don't want or need.

So your best option may well be a mid price receiver with preouts and an external power amp. The problem is that receivers are now crammed full, and are actually less capable in power output than older models. I personally use the AVP approach as I would expect trouble from a receiver and likely get it.

It is issues like yours that highlight that going forward amps need to be in speakers and not in receivers.

Using a powered subwoofer would greatly reduce the strain on that receiver....heavy bass is what really sucks the life out of an amp, especially at low impedance.
If you were mulling getting a powered sub, that will give you some time to reconsider your amp choice, or possibly solve your problem.

Yes I'd like to get a sub, I'm waiting for a good deal on the Monlith M-12 or M-10, how do you take the strain from the receiver once you have the sub? using the microphone calibration of the receiver?

He has oversold that. The real power band is above sub range. So having a sub will remove a little bit of power, but not as much as people think it does. The major power band is actually between 80 and 400 to 500 Hz, which is right in the baffle step compensations band of narrow frontage speakers, and where the impedance drops to provide the current and power for the baffle step compensation. Speaker impedance is actually high in the sub range, because of the tuning peaks of impedance. So actually adding a sub offloads the main amps very little.

What is an AV receiver you would recommend with pre out and which external amp would work for it? I can only purchase from Amazon so it must be sold there.

I would like it to be under $1000

Something like this Denon AVR-X2800H may work for you.

No pre-outs. Need to go up to the Denon X3xxx and above models.

How well ventilated is the place you have put the receiver? You can add external fans to help if ventilation is poor. If that volume scale (which is somewhat unique to Sony compared to other receivers) is similar to my old Sony receiver, that's quite a high volume level (think mine only goes to 70 max). What happens at volume level of 45-50?

How much costs an external pre amp?

Max volume is 74

45-50 is fine but I like it loud

This receiver has right and left pre outs and two sub preouts.

This power amp will do the job.

That is the only way I can get you under $1000.00 A receiver with multichannel preouts blows your budget before you buy a two channel power amp.

The above combo will do the job and you can add a sub when you get the funds.

I think that combo would prove to be very reliable.

Probably not a particularly good avr for those who like it loud with lower impedance speakers That space does look a little light on ventilation, I'd add an external fan before buying new avr/amp. Coolerguys.com or Infinity Aircom units perhaps.

ps It's an external amplifier, your avr would act as pre-amp if it had pre-outs.

That AVR-X2800H will handle 4 ohm loads according to the user's manual. OP shouln't need external amplification.

It's not rated for 4 ohm, is it? Just provides a dynamic figure at lower than 6 ohm? That's what Denon usually provides. Probably little different from the Sony realistically (actually the Sony has a higher wattage rating at 6 ohm, too....145wpc for the Sony, 125wpc for the Denon at similar spec). It could simply be a heat issue that could be solved for the Sony with fans....

1. See Page 34 of the owner's manual from the Denon website. It is clearly specified that it will handle 4 ohm loads
2. The Sony receiver won't handle speakers with impedance lower than 6 ohms (indicated in their user manual)
