Denon AVR-X3600H AV Receiver Review

[192kbps]

Is it 18Gbps or 40Gbps?

 

[OrewaBob]

I am using HDMI 2.1 48Gbps cables, if that is what you are asking. I am not sure what the speed of the HDMI is on the 3600. I tried using 2.0 cables and could not get full HDR to work reliably, switching to 2.1 cables fixed that
The AVR has worked perfectly for a couple of days with the left surround removed. I will try swapping, putting the left surround back in and removing the right surround to see what happens.

I consulted the customer service and they said that the X3600H is only 18Gbps.

Yeah, you are right. I plugged the surrounds back in and it went into protection again after only 20 minutes, and back into protection again after 2 minutes for several restarts. Then after unplugging the surrounds, all was fine for the rest of the evening. I will use it like that for a while, plug in one of the surrounds at a time to see if I can work out which channel. Will the AVR work with only one surround present?
My wife is over it and says buy a new one, but it is frustrating with such a new bit of kit. The 3800 and 4800 are so new that there are no reasonable discounts yet too! It also sounds like the 3800 is not an upgrade either.
I gather that the AVR will not allow me to use the rear channels instead of the surround channels if one of the surround amps is faulty?

You said earlier you checked cables and even changed plugs, but that was focussed on fronts and centre.
Did you inspect the surround cables as well? It could be as simple as a pet chewing on or a pinched cable.
Best to measure them with a multimeter. Check for a short by using both leads at one end (of an unconnected cable) in resistance mode. We want to see ~infinity here.

 

[OrewaBob]

Thanks, but I have checked that previously. Also, the AVC is reporting that it is a DC error not a short. Still working fine driving just one surround channel, I need to swap and try the other by itself.
If the problem is one channel of the amp, is that likely to be expensive to get repaired?

 

[Gharp23]

I noticed these popped up on A4L as factory refurbished for sale. Given that it's been discontinued for some time would it be fair to say it still has the ak dac chip?
Did they ever make newer x3600h with a different chip or was that the x3700h? Thanks

A month old I know but, Got an old amp or something you can use from the surround pre-out to power that channel?

Thats the 3700s, any 3600 should be as measured here, AFAIK.

Hello , i´m a new owner of a X3600H , bought it for 400$ , mint condition.

I have a power amp by purifi( 2x400W) , Two front speakers MA Silver 100 6G , and a SVS sub .

I also have a topping dac , E70 Stereo , it ´s possible to connect it to X3600h ? Would it benefit me to connect the DAC? And how to connect it? The internal DAC of X3600H is automatically desactivated?

Hi, I wanted to celebrate with you my purchase completed right now. Thanks for all the advice and thanks to this nice forum. I'll be back soon to stress you out! hahaha cin cin !

670 euros + 30 euros shipping from Germany to Italy. I was hoping to spend less but it's still fine. Now I'm getting rid of the x3300w.

HI! One thing isn't clear to me. here it says input sensitivity 1.2Vrms...but then it says maximum input 16Vrms.
Can you explain to me, please, why this big difference?
The amplifier has adjustable gains. I use it for a couple of subs.

...and....Is the 1.2v (approximately) output of the 3600 called Vrms? Or peak to peak? Thx
Thanks

 

[witwald]

Input sensitivity is the minimum input voltage that is required for the amplifier to reach its full power output. The maximum input voltage is the voltage that the inputs can handle before clipping of the waveform occurs.

 

[Taso]

Thanks for the reply, I had this idea too. Now I have confirmation of it. Is the value of 1.2Vrns valid for any of the 3 inputs?

According to the specifications, yes it doesn't matter which inputs, 1.2 Vrms will give you the rated output as long as you keep the gain adjustment the same for each case.
This is a class B amplifier, audiophiles typically would not use it for hifi, but I am sure you know that already.

 

[Taso]

ok, thanks for the information. Yes, I know audiophiles and their thoughts. It's great to my ears!
...mine is class H. I don't know what "2-tier" means though. Maybe you know it!

Hi everyone!
I am quoting Amir's review and hope that anyone can shed some light for me...

At first I tested it in normal mode and it could only go up to 1.5 volt before the amp clipped and sunk the DAC performance with it.

What does 1.5V mean in the real world?

I bought a Hypex power amp (LPA-S500NC) for the Fronts and switched to 11ch mode as suggested.
Either my hearing is simply limited, or my speakers don't need much power, or I simply do not listen to music loud enough, or all of the mentioned...
I hear no difference whatsoever.

I am now wondering if it is worth to keep the power amp, so I hope you guys can help me.
What kind of volume range can I typically expect at those 1.5V?
Is this an output that people would even reach in normal living rooms?

Okay, but you circled the 1.2 V in that attached photo under the GX3 column so I thought you had the GX3, the GX5 is class H, but it is mostly class B as well like the GX3. It has "2-tier" rail voltage, that's why they call it class H. 2-tier is the basic type of class H, there are some more sophisticated class H that has more "tiers", or even use infinitely variable (analog) supply rail. Those are sometimes referred to as rail trackers. This kind of class H is done to increase efficiency even further than that of the class B's.

The easier way to think of this is that the built in amps clipped at 1.5V which means

108W into 8
167W into 4*

Here the amplifier couldn’t double down into 4, so it’s a limitation of current — but if you have a pre-out and enable the internal amp, when the internal amps clip, so will the pre-out.

100W into 8 is a lot of power.

This is why I think it’s way more important to measure SINAD at lower voltage when it comes to preamplifiers/processors instead of DACs.

 

[peng]

but if you have a pre-out and enable the internal amp, when the internal amps clip, so will the pre-out.

That is one of the very few things that I think Amir is wrong at least in practical sense. The power amp may start to clip at that point, but the pre out did not. Amir just have his own way of defining clipping. Anyway, I failed to convince him that he's wrong but it is obvious that lots of asr members have been led to believe their Denon avrs could only output 1.4 V, yet measurements show they could output 2 V with SINAD >75 dB, often higher than some AV processors did, such as the AV7705.

Hi, I finally got my nice 3600 and I'm selling the 3300. I only use preamp outputs. I looked at the various menus but it's not clear to me how to disable all the internal amplifiers. can you give me a hand? Thanks again!

Like the 4300, 4400, and 4500, you can only disconnect the front left and right channel amplifiers from the pre outs. If you want to disconnect all of the internal amplifiers you have go with the 3700, 4700 or newer models.
