Rowe AMI Eagle questions

[mikennickiex2]

HI, brand new in here. we bought a used rowe ami eagle wall mount and wondered if anyone could help us? we need to know how to wire the external speakers up to this. and also how to wire the volume control button under the bottom back up? any help at all we would sure appreciate.

[Skeptic73]

Are the speaker terminals on top? If so it may be similar to a Rowe Storm and Berkley wall box. I have a book I can look it up and email diagrams if you think it is.

[mikennickiex2]

hello, and thanks! yes it is similar, I would appreciate any help, diagrams, etc. thanks a ton

[mikennickiex2]

how do we tell which watt amp is in this  rowe eagle wall mount?

[Skeptic73]

Unfortunately, I cannot upload photos for some reason? Could be my jr member status? If you would like I can email you some scans to your personal email? skeptic1973@hotmail.com. The attach choose file tab is
grayed out?

[Skeptic73]

I took some pictures of the diagram with my iPhone. I don't know if your box same as the Laserstar Wallphono.

[lilshawn]

aaand this is why i don't like the iphone... 124x166?? gotta do better than that postage stamp to see the diagram.

sorry.

[Skeptic73]

have the iPhone 4 and the camera is actually one of the best you can get with a phone. I had the iPhone since it came out and the original 2G camera sukked. But for some reason this website won't allow me to choose a file on the iphone or iPad to upload. So it was resized and emailed to open on desktop to share. I'll try with a different camera. And if you need an external remote I have a few.

there ya go! 

[mikennickiex2]

awesome, thank you SOOOO much! how many speakers can I hook to this thing? 4? 6?..................................... 4 will work but 6 would be perfect if thats possible?   I am using some JBL 5s       if I hook up that many how do I hook them? you guys here are great! really appreciate all the help

[mikennickiex2]

you mentioned an external remote, do you have the transmitter and the reciever? and how much? I may be interested once I get this thing all hooked up to some speakers

[Skeptic73]

Sorry, It's a wired external remote. I was looking into getting the wireless for my Jukebox also. I saw one on ebay a couple months back. I was outbid by like $1. It went for just under $100 with receiver and everything.

 for the speakers, you can hook up quite a few, but it's hard on the amp. be sure to keep your load between 4 and 8 ohms on each channel. being too low on your speaker load is REALLY bad.

i have done 6 speakers (in a parallel to series connection) on one channel (other channel was for outside.) no issues with the amp.

wired up 2, 4 ohm speakers in parallel (equals 2 ohms) x 3 sets of 2.... and then series connected the 3 sets together to get 6 ohms.

like i said you have to get your speaker load right, or else your amp starts getting really inefficient and runs super hot... them blamo!, blown amp.

[Skeptic73]

Could be why I am waiting on those Transistors to fix my amp!

[lilshawn]

do you know what ohm the speakers you are planning to use are? I can draw out a wiring diagram to be sure you get the proper speaker load.

also are you planning to run separate areas with different volume requirements? or just some extension speakers for the same room. I'll have you know, the speakers on this unit a pretty good, i think you may find you might not even need more speakers in the same room as the jukebox.

you can also run 2 separate volume controls and adjust them independently. though in this configuration, you end up with mono sound instead of stereo, but advantageous if you wish to run speakers into another area such as an outside deck or other room. since you can just have a little sound outside (as not to annoy the neighbors or still be able to talk) and be louder inside.

The minimum recommended impedance for speakers connected to Rowe jukeboxes is 4 ohms. The amplifier will be damaged if you use 2 ohms as it was never designed for such low impedance loads.

Also, be wary of speakers advertised as "8 ohm compatible". I've found that many of them are in reality NOT 8 ohms, but rather some other impedance like 6 ohms or even 4 ohms!

Rowe jukebox amplifiers don't like even a 3.2 ohm load.

When I wire a jukebox in a commercial business location, I will usually wire the speaker load to be 8 ohm.

It used to be back in the old days of the 1970's and early 80's we wired 70 volt "constant voltage" speakers to the jukebox because the locations were demanding speakers everywhere or they wanted ceiling speakers. That was never the best way for great sound. Once CD jukeboxes started becoming popular, many of our locations wanted better sound. So we went to wiring 8 ohm low impedance speakers instead of 70 volt ones. Naturally this meant much less speakers could be used. It is rare for me today to install more than two speakers per channel now.

To test the actual impedance of the speakers, you can use a specialized piece of test equipment called a speaker impedance meter. Currently, MCM Electronics has a decent one on sale for $129 until Nov 30, 2010 if you use the "source code" number G116 at checkout.

I have a pair of bose 301's I think they're rated 6-8 ohm. I do have a pair of 70 volt outdoor speakers. And I have a single Boston outdoor speaker. I'm not sure what to do? I recently bought a denon 600 watt receiver and have four bose 301 and a center channel bose hooked up to a PS3 over my projector. I have a video jukebox with music videos and movies on a hard drive running through the PS3. This sounds incredible. I almost don't need the jukebox, but I like like it. Our Basement goes the width of our house. I was thinking of a pair of bose from the jukebox on the far wall? My surround speakers for the theater are halfway in the room mounted on floor stands and the gym equiptment is behind them so The sound focuses in the theater area? I don't know what to do down there? I attached a photo of half of the room. I guess I'm scatterbrain when it come to deciding this? I have a couple touchscreens one a touchsmart and i was going to load it full of music videos and wire it into a preamp board to the jukebox and have it touch enabled selection for the music video and send the video over the projector? Mr foley just helped me get my ultracade software installed now I need a way to wire in controls cause its on a desktop system and the keyboard does nothing. He sent me the key map and I have a hagstrom KE18 with no idea if and how to use it? I also wanted to run this over the projector or mount one of my two CRTs 27 or 29 in the wall and mount a control panel to the wall. I have a nitehawk system from IT with silverstrike bowler running through the receiver displaying on my projector. I found cabinets on ebay but I'm not sure if I want a cabinet in my basement or to just build into one of the walls or leave on the projector. So yeah I have all kinds of stuff I don't know what to do with so any suggestions would be appreciated.

you lost me right after :

I have a pair of bose 301's I think they're rated 6-8 ohm. I do have a pair of 70 volt outdoor speakers. And I have a single Boston outdoor speaker. I'm not sure what to do? I recently bought a denon 600 watt receiver and have four bose 301 and a center channel bose hooked up to a PS3 over my projector.

the best this to do is stick a meter on the speaker and measure the ohm rating to be sure. as for your 70v speakers, you have a set of speaker taps for them, right in the middle (A1 / A2) easy as pie. your speakers should have an adjustment on them someplace to adjust how loud they will get. you can choose whether to run 4 wires or 2 for your outdoor speakers.

so just to be straight, your looking to hook up the 2 - 301's for inside and the 2 - 70 volt outdoor speakers for outdoors?

[Skeptic73]

Yes, I think so. Probably just the indoor for now. One thing I guess I didn't understand was the output is a shared load with the internal speakers. Whats the most I can give to the external pair of 301's and still have the jukebox sound good. I've done a bunch of testing with two pairs of 301's from the juke and this is probably how I blew the transistors on the amp. What is it pink and purple wire on E7 is full load to internal speakers? And will I have to change this setup to add the external 70V speakers when I get around to that probably in the spring?

[lilshawn]

you want to be sure of your ohm load. measure the speakers. often speakers that say 8 ohm are like 6. test to be sure because we don't want a reprise of what happened already.

if you just ran some wires from all 4 of your speakers then stuck them all onto one tap. take a look at what happens:

assuming all your speakers are measuring 8 ohm: 8+8+8+8 ohms = 2 ohms wait what?

yes! when all your speakers are the same and you hook them up in parallel (all of the positive speaker connections are connected and then connected to the positive terminal of the amplifier. same for the negative) the total impedance is the impedance of a single speaker divided by the total number of speakers.

it's eight divided by 4 = 2ohms

2 ohm load on an amplifier expecting no less then 4... equals bye bye amp.

now if you still want 4 speakers on your one channel you need to get your ohm load back up. we do this by running speakers in BOTH series and parallel.

when you run speakers in series, you simply connect the positive terminal of speaker 'A' to positive terminal of the amplifier. Then you connect the negative terminal of spkr 'A' to the positive terminal of speaker 'B'. Lastly connect the negative terminal of speaker 'B' to the negative terminal of the amplifier. If both of the speakers have an impedance of 8 ohms, the total impedance will be 16 ohms. add together all the speakers. now all we have to do is take 2 sets of speakers wired like this (two 16ohm sets) and we can run them in parallel to get 8 ohms. (well within the safe margins of the amp.)

perhaps a badly drawn mspaint sketch is in order.

If your internal juke speakers are set on the E7 taps then you cannot run ANY external speakers at all. The amplifier is already maxed out.

The lower the tap setting on the output transformer terminal strip for the internal speakers, the more power available for external speakers.

[ami-man]

Hi,

Ken is correct the reason for the output package is to balance out the over all sound of the jukebox and extention speakers. The E7 tapping is the maximum output  you do need to reduce the jukebox speakers down to say E4 and then connect the extention speakers to E3 or E5 to balance the sound.

Another way to increase the sound is to use a slave amplifier or amplifiers the into for these is taken from the Auxiliary input /output socket on the amplifier where the signal will be around 600 milivolts. I have used upto 3 x 250 watt slave amplifiers running a number of Bose 301's (the one we used were 8 ohm) so they were connected so a overall impedence of 4 ohms for the slave amplifiers we were using.
Bose speakers are very good  quality but very inefficient so you need a lot of power to drive them.

So, using the one pair of 301's rated at 8 Ohm which terminals should I use for the internal pink and purple and which for the 301's. Running the pair I'll just use two cables one for each speaker so I won't be calculating series or parallel loads. I can't test with an ohm meter because I'll have separate individual loads on each line. I want the best balance of sound in the room from the jukebox and the far wall where the bose will be hung.
      I think my mistake was leaving the pink and purple on E7 when connecting the external speakers.

[ami-man]

Hi,

Put the pink and purple on E4 left and E4 right make sure the black is on one of the E1's (it is normally on E1 right).

Connect your 301's across E3 or E5.

 Thanks, Ill try both and make sure nothing is overloaded.

[lilshawn]

Connect your 301's across E3 or E5.

thats negative to E1 and positive either E3 or E5.

just making sure we are clear.
