Zone 4 Question:

I just got a TV setup in my kitchen and am using the Zone 4 (HDMI) out to send a signal to it. This works great when I turn on Zone 4, but when I turn off the AVR Zone 4 gets powered off as well (as expected) and does not come back on when the AVR is powered back up. Is there a simple way to have Zone 4 either stay on or to power on upon power up of the AVR?

From reading the manual, I'm guessing the answer is no and I'm going to have to use a remote macro...I just wanted to ask the experts first.

Awww dang...I just noticed that the Main Zone will not output Dolby TrueHD/DTS HD Master Audio/Dolby Digital/DTS if Zone 4 is on....that's not gonna work.

Well, joining the club back. Ran into some snags and need to sell my amp and preamp so I grabbed a 4520ci new for under 1k, can't complain...

Yeah, getting some cutbacks at work and college football is my other big hobby, need to reduce some of my unnecessary toys and payoff a little debt to reduce the monthly bills. Adult priorities I guess. Ill end up about $1600 to the plus and have a new (not refurb) 4520, so Ill be fine

It's not like I am going all HTiB with a 4520ci LOL.

Yep. I did upgrade from 82II's and 62II to the 7II's and 64II, actually a higher efficiency. I am gonna miss that outlaw amp though...

I almost grabbed a 5200, but it was $300 more and a refurb. Seeing as I owned the 4520 and liked it, just stuck with it.

I ran into a similar issue - but the main zone will output the DTS and Dolby TrueHD in the main zone provided you are using a different input in zone 4 than you are using in the main zone.


The issue is the HDMI handshake completes from source to ALL sinks - and your TV probably responds as only being 2 channel capable (or 5.1 at best).


For my issue (described earlier in this thread) I was trying to drive a 5.1 system in another room via a Zone 4 HDMI to Optical converter that responded as being only 5.1 capable, thus having similar limits in the main zone.


My solution - a new (much less expensive) AVR that was 7.1 capable for the 2nd room.


I don't know what might work for you - depends on what you have available for cabling to your 2nd room as well as the inputs on the TV... perhaps component video and analog audio from zone 3?


So far as your power issues - on my 4520 the zones are all powered on and off individually - ie. If I don't power off zone 4 and I do power off the main zone - zone 4 remains on. So I am unclear as to what you are experiencing there.

I'm kinda curious what would be considered adequate ventilation outside of having the receiver in an open area.

I do have a replacement coming in so I'll report back to see if it was just a defective unit.

https://www.bdiusa.com/theater/mirage_8227.shtml is what I keep it in. I use the right compartment with the shelf removed.
My previous 1909 takes up a fraction of the space the 4520CI so maybe this furniture wasn't designed expecting such a beast of an AVR.

I have my equipment enclosed in a cabinet but have plenty of extra fans for cooling plus temp sensors.

Heat is a killer to electronics so a few $$$ more for some peace of mind.

You can see in back 2 120mm fans and 1 140mm fan on top of me 4520ci.

We can work backwards to determine the right answer. Starting with your current situation, where the fans turn on and are loud, can we agree that the ventilation is probably not adequate? So, there are two approaches you can take: provide a place for the AVR that has better natural ventilation, i.e. a different equipment rack/cabinet, or placing it outside the cabinet, on a shelf, for example. Or a second approach would be to add airflow to your existing cabinet, by cutting holes and installing exhaust fans. Whether the latter method is a quieter solution or not depends on the type of fans you install, but it will certainly prolong the life of the AVR.

Looks like a solid solution if I can find a couple quiet fans. Are these triggered to turn on with the receiver or how are they powered?

Currently have one of these powered off the rear usb, goes on and off with the avr as I'm temporarily using it in an open shelf rack with limited height options. Not super quiet, but once I lubed it it was better. http://www.amazon.com/gp/product/B00...ilpage_o00_s00

Mine are computer fans with a computer fan controller. I made it many years ago.

But the grills are from this company and they do have a thermal controlled solution. I would do this

5200 was/is $999 at Fry's on sale for a new one, but if you are not doing ATMOS then the 4520 is the way to go imo.

Yeah, I looked at the 5200 vs 4520 vs 7200. 7200 was too much $$$ and I would rather have the 4520 over the 5200.

Might as well enjoy your 4520 for a couple of years, then perhaps see what's new. That is what I'm doing.

It's triggered by a thermostat. Shuts off automatically after the receiver cools off.

Dang, thats pretty cool.

My AVR's have a pretty wide area but they still are found to be quite warm at the end of a movie. Just moving air and reducing the temp could pro-long life/reliability.

It doesn't sit flat over all that area. It is raised around the perimeter so the fans pull air through all the venting area. It "may" be more effective than two individual fans in the other configuration which leaves much of the vent area open which could result in the fans pulling some air in through them. I don't have any evidence to show that and no doubt either method is better than nothing. I use a window fan to help cool my house and I noticed that it was more effective if I used a panel to cover the exposed side areas. The fan blowing air in would pressurize the room and some air would go back out next to the fan instead of blowing on through the house and out another window. Probably not a huge difference...

Be sure to keep UNDER the unit dusted as well as these fans draws in air from the bottom and along with it, dust. I don't use fans. Never needed them.

Seems like these would be a good low cost, low noise cooling solution also.

My 4520 triggers the fans due to heat during a movie too. I want my receiver to last, both for me and whomever I sell it to on Ebay when I upgrade. I'll keep this fan for whatever unit I get in the future. They work great !

I always have a habit of feeling the top of an avr after a movie to see how warm and where, especially if it had some high volume levels. I also dust underneath and around once a week so the fan may be a good move for me.
