JL Audio CR-1 Crossover

Thanks Ozzy,

Should have the CR-1 today...

Hey Ozzy,

I'm about to finally take on the CR-1 project based on our system set up being very similar. Might be hitting you up for some pointers along the way!

As I mentioned we have similar set ups in that I will also be using the HT passthrough and running my 2ch set up from my DAC/Preamp to my amps.  Are you also running your 2ch through a dedicated DAC/pre to the CR-1?

Thanks!

Mike

Hey Ozzy,

I have the CR-1 up and running, but I’ve run into an issue.

im using scenario 3 where the CR-1 allows me to share both the subs and the front L/R speakers between my AV Processor and my 2 channel Preamp/DAC.

the issue I’m having is related to the fact that my AV Prcessor only has balanced outputs, which is forcing me to use a converter cable turning the balance connection to RCA so I can use the unbalanced inputs on the CR-1.  The balanced XLR connections are used between my 2ch preamp and the CR-1 as the set up guide dictates, while the bypass av processor uses the unbalanced connections.

The issue is; when I hit the bypass button, I get a nasty buzzing in the L/R speakers.  But when I’m using the CR-1 for bass management, there is absolutely no buzzing. 
 

it appears that the CR-1 doesn't like both balanced and unbalanced connections happening at the same time.  If I disconnect the balanced cables from the CR-1 the buzzing stops. 

i suspect it has something to do with the “cheater cables” connected to the AV processor converting the XLR out to RCA unbalanced.

I wonder if you’ve had a similar experience with your set up?

thanks!

Hello Northman,

just coming back to this thread now and noticed your comment on the buzzing issue while using both balanced and unbalanced connections. Did the JL guys help you find a solution?  I’m still dealing with this buzz when I use the HT bypass switch.

thanks!
