Crown xls drivecore 1000 question

[chepo06]

My question is to run it in bridge mode, do I have to make a 1/4" to a Y cable, or can I use just the channel 1 speakon cable?

[RFord04]

I believe the channel 1 Speakon output jack can be used for bridging.

You can use a 4-pole Speakon in channel 1. Connect the positive terminal of the speaker to 1+ and the negative terminal to 2+. Plug the connector into the Channel 1 output only.

This is correct. The amp will tie the inputs together for you. Use channel one for the insert.

Make the bridge cable. MARK THE AMP END. It's directional.

IMO I think it's easier to use Banana plugs off the terminals
+ to channel 1 red - to channel 2 red, piggy back another banana into the first one. Radio shack has beefy banana plugs, all you need is a a screwdriver.
When the DSP is set to bridge it will internally do what it needs. Just plug into channel 1, turn up channel one, leave channel 2 volume off.

Should be in the manual as well.

It's even easier just to buy an adapter cable to use your amp in bridge mode.

Hey y'all what I ended up doing is I set the amp to bridge mode. I had to use one of those speakon to 1/4 " adapters cuz I forgot my 610 Mesa is older and dosent have speakon connectors. Seems to be working.

[Steve]

I don't knpw what you got going on because I'm sure they make all kinds of adaptors but. your "standard" speakon > 1/4" is not going to get you where you need to be.

It's not that difficult. Amp end is 1+ 2+ the cab end is 1+ 1-

The hardest thing about the job is being able to see those minuscule little markings by the screws

Might as well take it out of bridge mode if you do that. You're only running on 1 channel at this point.

The advice about the rewired 4 pole speakon connector is correct. Or just get a banana to 1/4 " cable if 1/4 is all you have on the speaker.

For a cab with 1/4 jacks I'd just do a banana to 1/4". That's how I ran mine.

I'm interested in this setup. So for bridge mode with banana plugs and 1/4" on the cab - how would this be run?

I was looking at this cable:
http://www.ebay.com/itm/Musicians-Ge...item20cd0bc1d0

Do I simply go from channel 1 output on the amp to cab and then set the amp to bridge mode? Or do I need to have another banana jack plugged into channel 2 output? If so, how is that setup?

Thanks for the help

Edit:

Found the manual online : http://www.crownaudio.com/media/pdf/...ual_032410.pdf which shows how this can be done

what you are doing now works fine. since you are using a speakon to 1/4" adaptor, you don't need to do anything else. personally i would use a connector style adaptor, rather a cable that is speakon on one end and 1/4" on the other. needless to say using speaker cable. but what you are doing is correct. don't worry...

That's a big NO.

You need to have a specially wired speakon adapter to get the bridged output. If you use a regular speakon in channel 1 you only get channel 1 output, along with having channel 2 getting the same signal, producing the same output, without any load..

sooo an NL4 to 1/4"....its nothing specifcally wired about it....may i add that most of these adaptors are...

[No Neck Shrek]

If you don't want to change the pin in your speakon cable, check here - http://www.speakerrepair.com/page/ca...er_Cables.html
They should have what you want / need.

I used these cables for my rack system and they worked great.

[uhdinator]

Easiest way is if unsure if Speakon is a 4 conductor and wired correctly, is to unscrew it and open it up. Unscrew the wire connectors and remove the wires.

Unscrew the terminals on the amp and insert bare wires in the terminal side holes and screw them down tight.

The picture on the amp terminals shows you how to connect bridged mode.
White wire=positive goes to ch 1 +red post
Black wire=negative goes to ch 2+red post

Unscrew 1/4 end if you need to check.
tip=positive/usually white
Sleeve=neg/usually black.

Buy a $6 banana plug if you don't wanna spend more for a NL4 speakon and have to use 2 different cables if you need to switch modes or use the cable for something else.

NL4 speakon has +1, -1, +2,-2 connectors inside. +1,-1 are used if its wired for regular uses. +1,+2 are wired if its for bridge mode. So a standard speaker cable that only has NL2 Speakon connectors will not work for amps that use an NL4 Speakon for bridge mode.

If you look into the end of the Speakon you can tell if there are 2 or 4 conductors.
Some cables were/are made with NL4 but it is no guarantee its wired right for bridge mode. If it has 4 wires it was made to work for either mode.

Banana no bueno. Pull out easy, shock hazard.

It's no sweat to take a conventional cable with a Speakon^® NL4 to quarter-inch and convert it for bridged use. Leave the quarter-inch alone. Open up the Speakon^®, which will be set with the wires going to 1+/1-. Just undo the wire going into the 1- terminal and put it in the 2+ terminal. QED.

Normally, yes. But...

on the Crown it's not easy to pull out the banana cable... it inserts vertically into the back panel. It can't be inserted horizontally.



You'd pull the amp down before you could pull the banana cable out. I used mine like this with no problems.

Banana no bueno. Pull amp down, crash on floor.
