I used 1.5" RCA to TS patch cables from GLS Audio between the Oppo and my MX882. Make sure you're using a source that has mutl-channel output and that it's not being mixed-down to stereo by Denon Blu-ray player.


...or, as I discovered this morning, I managed to pull the RCA's out of the back of the Denon ever so slightly as I was adjusting other cables such that they weren't making good connections!

I'm surprised those RCA's slid off so easily...I'll have to tighten up the surrounding grippers.

If you have two units of rack space free to handle audio, I'd put in a ART MX622 line mixer and the Rane (or less expensive Behringer MX882).

The MX622 would give you three stereo RCA inputs as well as a couple mic inputs while the MX882 would give you individual volume controls for 3.1 sound. I used to have my system configured exactly this way up until last year when I when down to a single zone mixer due to space constraints.

My signal flow looked like this:

Oppo 103 (or Denon) Blu-ray player was directly connected to the MX882
Front/Left > Channel 1/2 (Main)
Center > Channel 3
Sub > Channel 4
Surround Left > Channel 5
Surround Right > Channel 6
MX622 Mixer Input > Channel 7/8

The MX622 line mixer handled mixing down a few different aux source such as a backup Blu-ray player and a few wired microphones which then ran to the last two channel on the splitter/mixer.

There's probably wiring software where I could diagram it better for you, but I hope that helps. It's a very effective config while giving yourself full control over all channels.

In other news, there are a few downsides to the Denon player you should be aware of. It does not support zoom modes for 1:39.1 content and it doesn't have any HDMI inputs. If it had those two things, I would replace my Oppo just for the size savings, but those are important features to me so I've stuck with the 103 for now.

Hope that helps!

Thank you, sir - $1345 later... Shocked...I'm on my way.

I'll need to order some cables once I map all the inputs and outputs, as well...

John

...and so it begins. 

Waiting on a couple more cables to run first bench tests in the warehouse before loading everything into the 12U wheeled audio cabinet.  Ordered some shorter cables, as well just to tidy things up a little

I get the feeling I need to inspect the internal wiring connectivity of each cable as we have balanced and unbalanced sources and loads!

John

Everything hooked up on the bench and all the speakers connected - running through a couple SACD Audio CD's and Blu-Ray discs to test.

I have no sound on the Center and Sub channels.  I'm pretty sure it's because we are going from RCA to RCA with a 1/4" TS adapter to plug into Channel 5 and 6.

Philip - how did you handle the cabling on those channels?  Perhaps I need to just get (mono) RCA to 1/4" TS cables? Or perhaps RCA to TRS?

My Film Festival console has 3 OPPO's (love them).
My Drive-in console has 2 OPPO's
All consoles have Kramer seamless switchers
The Denon is a nice unit
It would be nice since rgb is being squeezed out that all HDMI decks has 2 hdmi out

Hi RG -

I had this thread in the Receiver specific forum and copying over here because your post is very pertinent!

I've been doing outdoor movies on our property for friends and family for several years and assembled the audio components into a wheeled 12U Seismic Audio cabinet.  The projector sits on top of the cabinet during the show.  In addition to a master plug strip, we have a basic Panasonic Blu-Ray, a Denon AVR-3805 to decode the optical into discrete channels and then 2x EP4000 Amps with L/R going through one EP4000 and Center/Sub going through the other.

That stupid cabinet must weight 200 pounds and I'm just getting tired of that! 

So, I decided it's time to upgrade to save weight and save my back... I understand a Blu-Ray player with analog outputs to a Splitter/Mixer can do we what we want - but that's where I get in over my head and get confused.

Will be buying a new DVD/Blu-Ray with 7.1 analog output - really like the 1U Denon unit. (very hard to find the Oppo 103's at a reasonable price).
Will be buying 2x Behringer iNuke NU6000's to replace 2x EP4000's.

Removing the 2x EP4000's and the Denon will pull out almost 100 pounds of weight!

When it comes to replacing the functionality of the Denon (decode digital audio from Blu-ray, provide other inputs for iPod music, and provide master volume control) - what's the best way to do this?  We'd like to keep 3.1 sound capability. 

Some combination of Mixer/Splitter? Is it possible to maintain master volume control with a Rane or Behringer Splitter and then feed a mixer? Can we add a microphone input?

We already have a Christie Digital LWU505 projector and Peavey Sub/Speakers/Stands.


Functional Requirements:

1. 3.1 sound from movies - master volume control is very nice to have to easily adjust overall sound, discrete volume control can be accomplished with the amps
2. The ability to play music from an iPod (simple L/R stereo is OK, bass to the subwoofer is a nice to have when only playing music and not movies)
3. The ability to hook up a microphone is a nice to have, not a need to have.
4. Use the existing 12U cabinet, speakers, and projector (projector sits on top of the audio cabinet during movies)
5. Ok with buying new DVD/Blu-ray with analog 7.1 sound outputs
6. Ok with buying Mixer or Splitter (or both?)
7. Will be buying new iNuke NU6000's because that will save ~45lbs in the rack.

Speakers are Peavey 118 subwoofer (8 ohms) and Peavey PVX12 (also 8 ohms) for L/R/C...

I'm still unclear on the simplest way to have 3.1 sound - mixer, splitter, or both?

I appreciate your input!

Oppo told me the optical output can be downmixed to stereo on their Blu-ray players while still maintaining the 5.1/7.1 stereo analog outputs. My new plan is to put a optical to analog converter on that output so that I have a downmixed 2.0 signal going to the mains while using Oppo's analog outputs to drive the LFE/center channels.

If you decide to ditch your heavy Denon decoder for an Oppo player, it can greatly simplify your rack while providing the same functionality.


I keep getting confused - decided to break it down:

In the four years since I posted this, I've since switched to a completely different system. My rack now has:

Oppo 103 Blu-ray (used to decode audio to 5.1 analog outputs)
ART MX624 Zone Mixer (sub and center channel go to zone 2 for separate volume control)

This gives completely independent volume control of all 3.1 channels and takes up only 3 rack spaces.

The Octava HDMXA71 I was using before I sold because I didn't like it's functionally as a switcher and now that I have analog outputs directly via the Blu-ray player it is no longer necessary. For your usage though, it would probably work fine as long as your Blu-ray player supports sending LPCM surround output via HDMI or coaxial. Some Blu-ray players only output downmixed stereo output even over digital connections so double-check to be sure.

Honestly though, I'd go with an Oppo (or another player with 5.1 analog) and line mixer. They work really well together.


Interesting... I like the idea - but how do you keep LFE to the subwoofer only, or, conversely, not send center channel higher frequencies to the sub?

Would a 6-in/6-out device like the Rane SM 26S 6-Ch Mixer / Splitter - help with this?

I find the center channel is useful to center the conversation - we usually end up running the Denon in "stereo" mode to improve the volume on the L/R channels.

Certainly appreciate your input!

I think removing the analog audio outputs for consumer disc players has been mandated/required for new models. The device you posted will certainly resolve this problem, but bear in mind you must have the player decode and downmix the HDMI audio to 2ch LPCM in order for this device to work.

I happen to use a device that performs a similar function:
http://www.octavainc.com/HDMI%20switch%204x2_7_1audio.html
Expensive, but gives me a rackmounted switch along with 7.1 RCA audio. Nice.

Hello there - I'm looking to replace the Denon AVR we use as the surround decoder with something much, much lighter...would the Octava work with the Behringer EP4000 amps we are using to drive the Peavey 3.1 setup?

Inputs:
1.   BluRay DVD player with HDMI and Optical (Audio only)
2.   Ipod (for music before the show)

Surround Sound Decoder Denon AVR  (very heavy!)
a.   Optical input used from DVD
b.     "CD" RCA inputs used from iPod
c.   RCA pre amp outputs connected to amplifiers (below)
d.   Note that this allows me to adjust volume with the Denon volume dial this is nice to have but not mandatory.

Amplifiers Behringer EP4000
1.   Right and Left channels run through one
2.   Center and Subwoofer run through the other

Speakers 3 Peavey 2-way loudspeakers and one Peavey subwoofer.


The question is can I replace the Denon AVR with the HDMXA71?

Will the analog outputs from the HDMX work with the Behringer inputs?

Sincerely appreciate your help - we're trying to lighten the audio cabinet and that Denon weighs a ton!
10  Backyard Theater discussions / General discussion / Does anybody know if CB screens are still available direct? on: May 21, 2013, 07:45:24 pm

Hello Everybody!

Hope you are all as excited as I am for summer to start with outdoor theater.

I bought a 20x16 direct from CB in Hong Kong several years ago and it's held up very, very well....until I put it away slightly damp one time and the white screen material is now spotted with mildew and mold stains.  I'd like to buy a replacement screen...

I've changed companies since the original purchase and no longer have access to really old emails...does anybody know how to contact CB, or even if he is still selling?

If I can't get  a hold of him I'll take this screen to an upholsterer and see if they can sew in new material.

Appreciate any help provided!

Complete Sound and Screen - all you need to provide is the DVD player and a Projector and a couple extension cords!

We are upgrading our outdoor Movie Theater screen and sound system and our current system is available -

Screen - 128" x 72" (10' 8" wide x 6' tall) - true 16x9 screen aspect ratio, 1.5" PVC frame with Velcro at 12 key points, Screen is 1.2x gain blackout back true movie screen material. Height is adjustable to your backyard by buying a 1.5" PVC pipe and cuttin a couple pieces to length

Surround Sound Processor - Onkyo TX-SR504 - http://www.us.onkyo.com/model.cfm?class=Receiver&m=TX-SR504

Speakers - 6 total - 4x "Proficient" 2-way and 2x "Niles" 2-way, includes 6x 50'-75' speaker wires with banana plugs both ends. Front Left, Right, Center - Surround Left, Right, Center. The Front R/L & Center speakers mount to the movie screen frame, the three rear surround sound speakers mount on (included) poles

Subwoofer(s) - Acoustic Audio 15" powered subwoofer (I'll also include a Jensen 10" powered subwoofer that could just as easily be used in your house system).

I have original boxes for everything and will include a Rubbermaid tote that holds all the poles and the speakers in their boxes.

This system has served us very well for 2 years - only 12 movies in total - everything is in perfect working order. A couple minor scratches here and there but everything works great!

Our kids absolutely love outdoor movie nights and we've had many movie nights with family and friends over.

Not really possible to ship everything....I'm in San Diego and I'll drive up to 50 miles to help hand off this great setup.  Well over $1000 in original costs.

Hello Everyone -

I'm ready to pull the trigger on a couple Behringer EP2500 amps, 3 Behringer B212XL's, and an 18" subwoofer...

Just wondering how I'm going to power all of this stuff at events...

The Tech Rack has: Panasonic BluRay player, Denon AVR3800 head unit used only for preouts, Christie Digital LWU505 projector....adding these 2 Behringer amps seems like it will definitely trip a circuit breaker.

I can run 2 extension cords from the house, each from a separate circuit breaker, 1 for the amps and 1 for everything else, but those amps together could trip a breaker!

Note - I already have a 3rd extension cord  on yet another breaker running from the back of the house for the blower on the 20' screen!

Has anyone run Q=2 ~2000W amps off a single receptacle before?  I doubt I'll anywhere near running these things at even 80%...but I'm concerned...

Thanks,

John

Thank you!

Any preference for powered speakers or passive speakers with separate amps?

John


Do I get central volume control with both options?  I really don't want to have to walk around adjusting volume on each speaker during a movie...

The master volume control on your Denon will attenuate the preamp outputs, so yes you will get central volume control either way.

In both cases you should set the attenuation of your external (or internal) amplifiers to unity gain, and control the volume using the control on the Denon preamp.
15  Backyard Theater discussions / Speaker specific / Re: Unpowered PA Speakers + Home Theater Amp? on: May 15, 2012, 06:57:09 pm
OK....ready to pull the trigger on PA speaker system:

I have a Denon head unit that converts the BluRay Player Digital Audio Out to multiple flavors of stereo or surround sound with pre amp outputs...I'll be running Front Left, Right, Center this year (hope to buy more speakers for Rear Left and Right next year).

Now, the question is:

Passive PA speakers with amps near the projector/stereo, requires 120V AC power only at the A/V station...

Powered PA speakers with pre amp feeds.  Requires 120V AC power out at the speakers...

Do I get central volume control with both options?  I really don't want to have to walk around adjusting volume on each speaker during a movie...


One issue with using a std. low end home stereo unit is the wattage rating is generally where the unit bursts into flame.   Wink
