Behringer 2600 spring reverb - it's worse than I thought

Postby The Elf » Thu Feb 25, 2021 9:44 pm

I've been trying out the B 2600 in anger today. It's a very good synth in all but one respect - that dismal digital recreation of a dismal spring reverb.

For me a real spring reverb would be just as unwelcome, but I can report that this one does at least sound like you're playing inside a disused water tank - so there's some level of authenticity here.

HOWEVER... :headbang: :star: :o :madas:

This monstrosity has one very nasty additional surprise in store. It is, in fact, a mono reverb with the L/R channels in opposite polarity. At least it is on this one here. Flip it into mono and... the reverb disappears (almost a blessing, but still...).

Can anyone please confirm or deny that their B 2600 is the same? If they are all like this then there are going to be some red faces when stereo recordings featuring the 'spring' hit mono playback systems. If it's just mine then so be it. I'm as sure as I can be that there is nothing wrong with my connections. But I can't believe I'm the only person to notice this, if they are all the same? :headbang: :ugeek:

For myself it's pretty much a non-issue. I'd already made an insta-bypass around the reverb, even before it was switched on, and it will be returned and remain that way. It's taken from lunchtime until now for me to be even curious about the reverb.

Am I right in thinking Berhringer have a history of adding mono digital effects to several of their synths?

The Odyssey has a stereo effects processor and only a mono output (it even lets you select a ping/pong preset). I'm not aware of any other anomalies.

The 2600 has stereo outputs, but this time they add a mono effect? :headbang:

I haven't see this polarity trick used since the Korg DW/EX-8000's delay effect from the mid-1980s!

I like listening to The Elf complaining about gear. I went to pour myself a shot of Jura when I noticed this thread.

Well, TBH this defect (if such it is) will affect me least, so it's no biggie :lol: . For anyone that creates a stereo mix, including the pseudo-spring, that gets played over a mono PA... Oh dear...

Other than this bit of nonsense it's a fabulous synth. I never wanted the reverb anyway, so I'm a happy bunny. :lol:

What? spring verbs are so cheap, what’s with digital? Behringer are loosing me (lost me?) by the second.
Still, they haven’t quite made it to the big time yet, Safari and Google spell check still doesn’t auto correct their name.

There's something very reassuring about this thread.

Some people are telling me the original 2600 was the same, others that it was a stereo spring. I have no idea one way or the other.

If it was the same then that's:
a) Fair enough :thumbup:
b) Just as daft :lol: :headbang:

I was thinking of starting a 50p charity jar every time Elf complains about spring reverbs, but I don't earn enough.

That polarity issue is a shocker though.

A really intriguing thread, well done Elf :thumbup:

I googled ARP 2600 service manual & the one that came up

http://dl.lojinx.com/analoghell/Arp2600 ... Manual.pdf

has the reverb module circuit on page 28 of 53.

the mono output of the reverb unit goes to 2 separate opamp circuits on the way to the main outputs. Those opamp +/- inputs are used differently on the L& R path i.e. one is inverted .

Well done, mate. :clap:

Well, no-one can complain that it doesn't try to be authentic then!

I predict a spate of Internet postings about disappearing reverb! :mrgreen:
