Hey Everyone,

I recently purchased a Behringer 2442 and a Delta 1010; I have a few questions regarding balanced / unbalanced connections.

1. Should "Aux" inputs/outputs all be balanced (+4) if possible? It doesn't specify in the Behringer manual if the outputs are balanced/unbalanced however my rack units have the both options.

2. On the topic of "Aux" connections; do they run out of the "Aux Send" then back through the "Aux Return" into the same channel?
Or does the "Aux Return" go to the separate Aux/FX section with only the original signal continuing through the channel?

3. I have 8 unbalanced outputs from the Behringer 2442 going to the 8 inputs of the Delta 1010 (set to unbalance to match the desk).
Although these are unbalanced, when I return from the Delta 1010 to the Behringer 2442 should the lines be set to balanced?

4. For any Delta 1010 experts out there, I have some distortion in my left speaker occasionally, I have checked all mixer lines/inputs/outputs and it doesn't matter which return I am using (1/2, 3/4, 5/6, 7/8) the left speaker is always the issue, I am certain it is either a software or line issue.
Has anyone had this occur before, and does anyone have a solution to the issue?

Thanks for your time,

Tomcat
 
My only question would be why you have the Behr in the signal chain at all. It definitely could be compromising your signals.

Hi Tomcat. It is quite evident to me why you are using the Behringer 2442, the 1010 AI has no mic inputs! The electronics of Berry kit is quite decent. My son and I made very acceptable recordings using Beh' 802 into a 2496. The 802 has been replaced with an A&H zed10 which IS better but only marginally so (much better built tho'but!) .

This is after all the forum for HOME recording, we can't all run to Prisms and SSL strips!

But TC, Google "Behringer 2442 block diagram" (they stupidly no longer put it with the main manual!) . This will show you that there are only two "Aux sends". You need to feed the 1010 from either the inserts (special lead) or direct outs. Unfortunately the latter are post fader and might not be ideal. Both feeds are unbalanced, that solves that one! But so long as the runs are shortish, under 5mtrs of decent cable you should have no problems.

Re the distortion. If you are feeding the monitors from the CRTL room outs try the Main outs or vice versa. This should eliminate or damn the mixer.

Hey Dave,

Thanks for the reply, below is a diagram of how I am running my chain.
SEND: Mic > Line Input 1-8 > Direct Output 1-8 > Delta 1010 Input 1-8 > Computer
RETURN: Computer > Delta 1010 1-2 > Line Input 13/14 > Main Mix > Monitors

The "SEND" chain is "Unbalanced" once it hits the "Direct Output" which is fine as the leads only run 1m.
My question is, should my "Return" chain be "Unbalanced" to match the inputs, or can I make it "Balanced" to get a better return signal?

-------------------------------------------------------------------------------

Regarding the "Aux" chain, these are going to a separate rack compressor.
My question more specifically is; will the signal travel to the compressor, then come back into the same chain so that the "Direct Out" signal is compressed? Or does only the original signal reach the "Direct Output"?

Also, should these "Aux" chains be "Balanced"?

-------------------------------------------------------------------------------

As for the Delta 1010, I don't believe it is the mixer, I'll explain why as simply as I can.
It is only the LEFT channel that gets distorted, if I patch the RIGHT channel from the 1010 into the LEFT of the mixer there is no distortion...however, if I patch the LEFT channel from the 1010 into the RIGHT channel of the mixer the distortion moves to the RIGHT speaker.

I'm guessing it is the lead however I thought someone may have seen this issue before.

Cheers,

Tomcat
 
The only real advantage of running balanced line (as opposed to mic) feeds is the 6dB boost you get from a "proper" two amp drive circuit.

Since the spec for the 1010 does not show such a boost I can only conclude that they are "impedance" balanced outs. Still useful but no real advantage for short runs. Yer takes yer money.....!

You have systematically proved that the distortion is neither the mixer nor the speaker so that leaves the 1010 left hand channel or, as you say the lead. VERY unlikely that a cable would cause distortion but easily proved.

Sorry but it looks like the AI is bust.

Dave.
 
Thanks for the reply, I will look more into how "Impedance Balanced" channels work but I understand what your saying.
Does this mean that running a "Balanced" return will not give me any real advantage? Other than the dB increase of course.

Well using the balanced option can't hurt! (actually it CAN with twin amp or traff balance. You have to be very careful not to get a phase swop) .

Balanced line working comes into its own for long runs or situations where many cables are crowded together and noise, crosstalk and even instability might be a problem. For short runs and small channel counts it is rarely needed.

Mic lines of course must be balanced since the voltages are so wee, only microvolts at times.

Dave.
 
I think I will just run "Unbalanced" to be safe, nothing is running further than 1 meter.

As for the Delta 1010, I also have a 1010 LT so I might try that and see what happens, or maybe some alternative drivers. I'll post the results up if I find a solution.

Thanks again for your assistance!

Ah the LT! Well that should prove your distortion problem and it is of course unbalanced (cept the XLRs) .

You could get a rake of RCA-RCA leads cheap from your equivalent of our RockBotton and a handful of these...http://www.maplin.co.uk/1-4-6.35mm-plug-to-phono-socket-adaptors-1280

Don't pay those prices mind!

Hey Everyone,

In relation to the Delta 1010, I found a solution the the crackling noise in my left speaker.
Thanks to some advice from another forum I disabled the C1E, C3 & C6 and the issues stopped.

For those who have the same issue, these setting are found in the BIOS menu (available during startup) under CPU Management.

I have tried disabling only the C1E but this didn't solve the issue, however I have not tried disabling only the the C3 and/or C6. I will test these tonight and repost, there might be a happy medium between performance and power saving.

Cheers,

Tomcat
