Pioneer SC-25 and SC-27 Receiver Thread - Page 172

post #5131 of 5240
Question -- Do the optical out interfaces on the back of the SC27 'reduce' output to 2 channel stereo, or is the multi-channel source format (5.1, 7.1, etc.) passed through ?

Context -- I have a pair of headphones that support and render 7.1 sound (Astro A50s). To date these have been plugged into the optical out of my XBox 360 and preserve the spatial separation accordingly. I would like to attach these to my SC27 so I can use them across all of the the audio sources the flow through the receiver. Will this work and retain the 5.1 channel separation, or will that original channel format be lost?

Thanks.

Couldn't find anything in the manual, but IIRC optical will support 5.1 but not higher due to bandwidth limitations of the optical link.

Not sure if this is the right place to post this, if anyone knows of a better place please let me know and I will move it there. I recently picked up an SC-25 for an incredible deal ($66!) at a local thrift shop. The only thing missing was the mcacc setup mic. My guess is it got thrown out with the box. After reading through parts of this thread and doing internet searches, I've found that pioneer does still have the mic in stock for $40. However, I've haven't been able to find any used mics for sale. From what I can tell the APM7009 mic was used on a few different models. A buddy of mine picked up and sc-35 which was also missing it's mic. I would think that at this point there has to be a few people who have the mic and no longer have the receiver, whether they sold the receiver or it died on them. Has anyone had any luck finding a used mic? I realize that the $40 isn't a huge price to pay, but it feels like a waste to me buying something new, that people may have just lying around. Thanks!

A quick search on eBay turned up 5 starting at $25.

It took me less time to search eBay than to type this response... biggrin.gif

Where the heck am I when these deals come up. I have a freind who went to a garage sale and got in pristine condition one Pioneer Elite VSX 56TXi for $10!!!!

I offered $150 and he said no, well his wife said no.It sits on top of dresser collecting dust and its all out of smite I tell you. I want and she has the power.

I just want it to use in my garage.

Geeze.

and I just some guy selling supposedly "NEW" Pioneer Elite VSX 43. Now where he did come up with new Pioneer Elite VSX 43?

$10 bucks. come on
post #5138 of 5240
You'll find out why those things are only $10 when you get them home.

There are some great deals out there. But check them out carefully before buying, or be willing to lose the money all together. I've bought some good-as-new Infinity Beta 20's for $30 and a C360 for $50 on CL. Ex-husbands/boyfriends stuff.

I'm also finding some things for sale on ebay are coming from Electronic Waste sites. "Powers up but no further testing was done" Avoid like the plague. They look perfect, but they ended up in e-waste for a reason. If it looks to good to be true it probably is.

Anyone notice their sc25 throwing excessive heat? Maybe I never noticed? I have worked around that thing connecting speakers and what not and have never noticed the heat coming from it like tonight. Any ideas?
thanks
post #5140 of 5240
My SC-27 has always run fairly warm. You might check the vents are clear and the fan is operational (I think it has a fan, too much stuff in my console and it's all at home and off at the moment).

post #5143 of 5240
A lot of the time the hottest part of mine is over the processor or power supply, not over the amps.
post #5144 of 5240
I use my SC-25 as a prepro and it still gets very warm. It isn't the amps creating all the heat. I do use fans on all the gear in my cabinet. All Cooler Guys stuff, works great.

These for my power amp

and these for the cabinet behind

post #5145 of 5240
Thanks for the replies. The back of the AVR is cool. Its in the front , over the vents (duh). But the unit does not feel warm in the back. Is there a fan in there? I have never and still do not hear one running. I may connect a small fan to it. It sits out in the open and not in a cabinet.We also run it almost all day long. It been a great receiver and I have no plans on swapping it out anytime soon, not yet at least

Thanks again folks
post #5146 of 5240
yes there are fans in the lower amp section that work on slow speed & blow from the left side to the right as you face the front. that's why keeping space on the sides as well as top is important. fans increase as temp increases but at no time are really prevalent sound-wise.

the top will be the hottest part since the video processor - HDMI card is right underneath the top and it is what creates the most heat, 2nd to the amp. you should have min. several inches of top clearance, the more the better. I have 10" over my SC-09TX and about 9" over my SC-68. but many get by with less. I don't use external active cooling but the receivers are open face, no closed cabinet doors.
post #5147 of 5240
I have my AVR out in the open. Does anyone have a clue if the fan is accessible and user replaceable? If its too much or a hassle I may just mount one externally and let it do the job. I pretty sure the AVR is hotter than before. Even the wife noticed the heat and she cleans around it often
post #5148 of 5240
just did a search. I see where the fan is mounted. looks like an easy swap. But you know what they say about looks

I could be mistaken here, but I think the V1.74 firmware that Hkan posted on his website is for a Pioneer Blu-ray player, NOT an AVR.

The most recent SC-27 firmware posted on that web site is AVR_09_1055, which is 3 or 4 years old. I think that 1055 firmware was meant to resolve the occasional failure of the AVR to respond to the remote power-on command.

+1. That was the problem that drove me to try the upgrade, and it fixed it.
post #5152 of 5240
I`m thinking of adding a HDMI matrix to my home cinema and use it together with my SC-LX72, up until now i have connected my blu-ray player directly to the dedicated bd-in HDMI input but if i connect the player to a matrix instead, should i still use the bd-in input even if i have several sources connected to the matrix?
Or should i use one of the other HDMI inputs instead? If so, do i lose anything by not using the dedicated blu-ray HDMI input?
post #5153 of 5240
If you are using an HDMI switcher before the AVR it should not matter which input you pug it into.

Ok, good to know. I will be using the matrix/switcher before the AVR.

try selling it on Amazon...I bought a Pioneer SC-1222 last year about this time and sold a Yamaha A1000 for about $100 or so less than I had paid a year earlier...worth a try.

Is there ANY WAY to pass a 3D video signal thru the SC27?

Nope, sorry. Unless your source device has two HDMI outputs, you need a HDMI splitter, and use a separate HDMI input on your TV.
