Buzz 2.2 just walked in... Dynamics Plugins

Buzz 2.2 just walked in...

Happy holidays to me with a Buzz 2.2 mastering version with Palazzo's here along with my blue 315 and soon to be departing Sontec 250c.

First thoughts on the Buzz.....well maybe it needs to warm up and maybe it just took a journey from one coast to another....
getting 60hz bump when any lmf or hmf channels in. both side hmf full knobs scratchy with a weird resonance on channel A.
Noise floor of the buzz and blue are almost identical when all channels out and just the unit in the path.

Comparing the Focusrite to the Buzz-two different beasts. The Buzz different than the low end push of the 315 and the Blue is nowhere sweet like the Buzz in the top end today. The Buzz and the 250c both are very sweet in the top.

Before more reviews and comparisons I am going to try to figure out the Buzz issues and let her warm up more.

And warm up it will. you'll be able to fry an egg on that unit.

60Hz bump...sounds like an earth loop?

Maybe try an earthing cable to your rack? Try re seating the boards as well.

Yeah I am posting premature... but had to spread the excitement past my room. Eq overkill in here for day or so.

Will have more time to put the Buzz in a short direct loop on its own power etc.
Never came back from xmas with lacquer backup work...

Well, congratulations I hope!

I'm curious to hear how it all works out indeed. Why did you decide not to go with the Elmas by the way? My TG is chock full of them and at 30 years on I'm really glad those were the choice of the EMI techs.

Palazzos seem great to me. But I do not know the feel of the Elmas(not sure what lives in the 315).

The issues with the noise and scratchiness only things slowing me down with the unit

sad to hear that, maybe it's a defective unit? did you try to speak with the developers?

I've emailed Buzz and also lots of emails with current owner(its here on trial/loan). Will get it sorted

The 250c does really still sound great next to Buzz. The small Sontec still has 'the sound' and naturalness. 2.2 REQ can do what the sontec was doing for me and as well. Obviously for mastering purposes the 250c almost made me fearful while matching frequency+bandwidths side to side. I was very conservative with it is use other than the shelves, which I stopped using 70% of the time once the BAX arrived.

Hi Dietrich, the 60Hz in the LF & LMF bands can be picked up through nearby gear/power supply's. There is adequate shielding inside the unit but it's still very sensitive to picking up noise through the LF bands. Talk to Tim Farrant directly he has been amazing with the support he has given me for my unit. If there is any faults he is quick to respond & gets it sorted.

My unit has a higher noise floor than the Sontec MES-432 but I find the REQ-2.2 is seeing more of the workload than the Sontec these days.

Hi

I plan also to invest in the Req 2.2 next month. You are not the only one having this hum problem. That's really annoying. Please let us know when and how you have solved this.

Spending time moving it around in the room, away from other audio lines and power. shutting off other gear as well..

Here is with saturation 6 on....

Maybe some Mu metal wrapped around the chassis would help?

Post lunch troubleshooting....

Off came the top. Reseated all that can be reached without removing things.
Channel A is good to go.
Channel B seems to have something going on with the LMF card.
The Buzz is a complex beast inside. Beautiful construction. I am not going to attempt to swap channel LMF cards to further investigate.

Looks like this unit will head back to NZ or to current owner next monday....

To note: all gear turned off except convertors, computer and buzz. direct signal as well. at least issue seems isolated

When I first engaged the LF when in the rack the left channel went out completly. I pulled it out spoke to Tim right away, tapped the relay with a pencil eraser as suggested. I never had the problem again. Tim sent a bag of relays just in case. Great eq Great customer service. when a unit like this travels this far it may not be perfect at first.
By the way my noise floor is about -85db with all bands in.

Thanks Ed. I emailed Tim this morning and awaiting response for possible similar fixes.

Only issue is shipped off 250c today when thought would have buzz for month or buy it

-80db is not horrible. i had a similar problem with my API, and API said their units are calibrated to -85 or even -75... (i forgot which)... -80, in my opinion, isn't great, but it could be factory calibration.

API had me rotate the power transformer inside my unit, which brought the low freq noise down 5db into a more acceptable range for me.

should find out what the noise floor of the buzz is calibrated to at the factory.

like i said, -80db may be normal.

Buzz on Hum

I'm sorry you aren't yet thrilled with the Buzz, D. You noticed no buzz coming out of the unit, yes? That's because it nulls all buzz. However, it is known also to generate some hum (as trade-off). You will need to follow this unit with a pair of Hum Bugs, by Rupert Nøise (or the new stereo Hum Dinger, which is matched, but does generate some buzz);

Ok this Buzz about to take a journey back to NZ. Will check it out after its ready for me.
Hard to have concrete opinion about it until I can use it as designed.

Visited the repaired Buzz, now complete with the Elma's.
Was a pleasure to use. Really able to get in there without past issues and use it.

Of course that one is off the market.
