Hi-
First post here - Delighted to find this place, what a resource! never new it existed until I googled ev dc-one and up it popped so good find.

I recently invested in an EV tour x system (2x 1152 4x 1181 2x Q1212 and a DC-ONE)

Having great fun when running full range and just using the 1152's and one Q1212 for light gigs where not a lot of oomph is required.

Using the whole system though has not been so much fun: the last night out when I introduced the subs into the system I had to do a lot of (rack) EQ to balance it out.

My problem is this: it just seems like the subs are too powerful or are acting as if they are too close to the source - for example as soon as I push for any volume from a line on the desk that has a microphone as source input I get feedback in the <100hz range.

I have never had this problem before and on the night i went back to 'back up' using the old system with rack xover and EQ -

it sounded like the kinda mess you'd get in if you put the subs on the stage and the issues that come with that - for the record The subs are 3 feet in front of the stage left and right and problem manifested with stage monitors turned off so all FOH related.

first mistake - no laptop with me and didnt know the editor well enoug in a panic situation... lesson learned...

I was a bit dissapointed as it was my first night out with it and had hoped to be as equally impressed with the subs included than i had been with the 1152's on their own!

So... I have been going through the dc-one editor (In fairness this is my first use of a digital unit for managing xover eq etc so no doubt is my lack of understanding of the unit) looking at my presets - One thing I notice is that the dc-one xover has a 6db bell lift at 40hz which would explain alot - as well as that lift in the crossover the output channels for the sub have bell eq boosts of 3db at 50hz and and 2db at 200hz

This seems like a very strange starting point for a system though it is the official preset for 1152+1181 sub.

so I am wondering does any one have experiences with this dc-one unit and speakers?

Which microphone were you getting the "rumble" from... If it was the vocal mics, you could have rolled the high pass up on them to ~140... Or if you felt you had too much sub, you could have just dialled back the amp...
A couple of quick options on the fly....

For sure. The first thing I did when I heard the lows so strong was dial back the amount for the sub's. The balance of he eq was out of whack though so I switched to me old system out for comfort and speed in the given situation.
My query was more about the standard factory setting for 1152 and 1181 in the dc-one having what appear to be odd low hz boosts for a starting point.
Thanks

Liam,
How did the system sound with regular source material such as a CD or a known (to you) reference.

Hi Dave - Very thick in the low end; I had little time and didnt want to look silly so quit trying to diagnose and understand what was going on at the time. immediate reaction was to lower the sub amp but even though it reduced the lows the eq of the system sounded a bit off and i reverted to old setup.

It was foolish to expect it to be plug and play! ha! I must confess I was lured by the fact the dc-one had presets for my exact speakers including amplifiers for the limiting settings so was expecting a hassle free situation..

I'll have to read through the manual some more - I think its just a question of understanding the digital crossover element in the software ,
If i compare it to my old rack crossover I guess the db slider for each frequency in the crossover software acts the same as the low/mid/high output gains on a standard rack unit
there'll be nothing for it but to set it up at home to dial it in to a good starting point.

I still think the pre-mentioned dc-one crossover gain and low q boosts in the output eq for the sub channels is a somewhat bizarre starting point.

Liam, boosts in that area are not uncommon.. Just to confirm, I went to the recommended preset page for eaw for example and there are several boxes that they spec a 6db boost at 30hz etc... In conjunction with other processing and peq points, I've seen this "dampened" down somewhat, but none the less... It's recommended.

Thanks Shane -

I do notice in the presets that there is a 6db boost in the 1 x 1181 file and no 6db boost in the 2 x 1181 file..... maybe it was as simple as that.. maybe i had the wrong preset selected. Operator Error..... oops :blush:

Indeed with the Q1212 putting out extra power due to putting out more watts at 4Ohm in conjunction with the incorrect "one sub per side" preset it would have caused things to be weighted quite wrong...

Anyway, I will update to confirm my mistake!
