Hey guys, I have a question about the Thru jack on my VH4. I guess I understand the premise of it...maybe? But what's the practical application for this feature. I feel like I'm not using a potentially really awesome feature of my amp. Thanks!
 
Refer to manual; as can be checked on the Diezel site:

3.1.4 Signal Splitting via “Thru” jack
The “Thru” jack is wired in parallel to the input jack. You must be careful not to hook up low impedance tuners or other devices to this jack, because if you do, the signal portion that is split into the amplifier might be compromised. In other words, you want more signal to go into your amp then into your tuner or other device. This jack was designed to be used for high impedance tuners or to go into a second amplifier input stage. You can try this out by plugging a secondary device into this jack while playing, and listening to your tone. If you notice a change in sound quality or volume, then you should not use the device in question at this jack. There is a better solution to connect a tuner anyway. See section 3.3.2
 
Yeah, I've read the manual. I guess my question is what is the advantage of running that jack into another amplifier? Is it just if I want to run two amps at once I can use that instead of an ABY box? What's the practical application?
 
I don't know which purpose it should serve, either. The manual says not to use it for a tuner (unless it has really high input impedance to act as a small load). But when used for splitting the signal to two or more amps, I'll promise you nine out of ten times you will get hum issues, as it's not isolated.
Tell us why it's there, Peter!
 
This is another thing that is genius on the VH4!
It can be used for Slaving as well as a courtesy "Split" to drive separate preamps.
This is also a great way to keep your tuner out of the signal path. Lord knows you do not want one of those nasty things degrading the sound of your $4500 amplifier.. Please tell me none of you guys run them in line? ;)
 
As the Thru jack is wired in parallel with the Input jack, it DOES affect your input signal when you plug a tuner into it! Depends on the input impedance of the tuner, though.
 
As long as you don't return the signal I don't see the tuner affecting your signal when used in the Thru jack.
The same way that if you "slaved" a couple amps together I doubt the input impediance would be much different at the last connection. It seems the whole concept is based off the signal intergrity.
"Slaving" was probably the primary concept behind the VH4 Thru.

Click to expand...

i run all my effect-pedals in the insert of the clean channel besides the volume pedal and the tuner, which i run in front of the VH4S (in line). the sound i get like this is great and i really can't complain to have lost sound quality...
