Hi....
here is my question: is the general serial loop placed frontside the parallel loop or benhind?

Preamp ---- serial ----- parallel or Preamp ----- parallel ----- serial ?
 
The channel serial loop inserts are placed before the master serial/parallel loop if this helps.
If you choose to operate the master loop as serial or parallel has nothing to do with the independent channel serial loops.
For eg. If you put an EQ on the loop of channel 2 and then a delay in the general parallel, the sound that is going to be processed by the delay will be the EQd one.
 
ok but my question is not about the channel inserts, I just want to know the place of the general serial and the parallel loops:

preamp ------- general serial -------- parallel
or
preamp ------- parallel --------- general serial ?
 
...or maybe you want to say that it's not possible to use the master serial AND the master parallel at the same time?

However, there are 2 master sends (1 permanent and 1 progamable).....

so...?
 
I thought there were 2 master loops and not one switchable between serial and parallel.....
 
There is two master loops, with:
-One send that is permanently on (send 1)
-One switchable/programmable loop (send 2)
-One serial return
-One parallel return

The config for master loops is:
- Preamp--Parall--Serial--Power amp

I have found this configuration somewhat annoying, because with my current setup I cannot have delay effects (processor in Send2/parallel loop) in my presets that have modulation effects (processors/pedals in serial loop) in them. Well, of course I can, but i.e. Whammy, EQ, Lo-Fi, etc. are located after the delay send, thus the absolute output is a mix of "dry" signal with delay and wet modulated signal.

I would appreciate if someone would have any advices for me either?


There is also the mentioned serial loops/inserts for every individual channel which are located before the master loops:
- Preamp--Ch Insert (serial)--Master loops--Power amp
 
oh ok...I wish the serial was before the parallel, because it would allow to put a noise reducer like the Decimator in the serial and use effects like delays, reverbs, etc...in the parallel.... but if the serial is after the parallel, it becomes impossible..... :cry:
 
I disagree with you. There is many players (including myself) who use noise reduction system, such as ISP Decimator Pro Rack G, with their VH4 and especially in the serial loop.

Actually, I think in terms of noise reduction it is a way better option to have the serial loop and the noise reduction unit last in the chain. Thus, also the potential noise created in the parallel loop is eliminated.
 
ok, but if the noise reduction system is at the end of the chain, it can be a problem with effects like delays and reverbs because the end of the delay/reverb will be cut since the signal goes below the noise reduction system's threshold...Am I not right? :confused:

Yes You are right. I was also very sceptic about this issue, but so far I have been satisfied without any dramatic loss in the delay tails, etc. Also, another beautiful thing with the ISP Decimator (rack versions) is that it is dual channel operated and the channels interrelate. Due to this it does not cut your notes - if only adjusted correctly. But Im sure that You are already aware of this.

However, this conversation made me wonder that is the parallel loop really located before the serial? I wonder, because my effects "say so", but my delays do not loose their tails. I have to check. Maybe Peter or someone else of the Diezel-tech-Guru-family might also enlight us with their knowledge. Thank You. :)

I try to manage some time today and double check the loop configuration so that I am not talking complete BS to you.

Im sorry for the inconvenience and possible incorrect information.
 
I just got myself a cup of strong black coffee and while drinking it I think I figured out my loop problem. In other words, I might have been talking "holes to my head" when saying that the parallel loop is before serial. I apologize. :aww: :no:

The reason why my delays (processor in parallel loop) does not have the modulations (processors in serial loop) is, because the parallel send is before the serial return. Of course this does not mean that the whole prallel loop as such is before the serial loop. It may well be that the parallel return is actually located after the serial return, which would explain why my delay tails are not cut off.

Sorry.

Could someone confirm/ditch my theory?
 
To answer all incoming questions:

The parallel loop is parallel to the serial loop.
The switchable (also serial) loop is before the serial loop and the parallel loop (Herbert).
The reverb is before the send (combo).
 
well, it means that I can have for example a G-force in the parallel loop and a decimator in the serial loop without risk of loss of the delays/reverbs tails...... :yes: :lol: :LOL: :D :thumbsup:

I receive my VH4 next week, but I have to wait e few weeks for the decimator....but I fell happiness is near.... ;)

Thank you Peter for those informations.... :thumbsup: :rock:
