Unison Hi-Z (Apollo Twin) vs Standard Hi-Z (Silverface / FireWire) Comparison 

I used the SVT. The B15N is fantastic, though.

Thanks, Ken! Yes, there are some things that audio examples alone can't capture.

The impedance aspect works on Mic, but just not Hi-Z, as you're probably aware, since that technology aspect didn't exist yet. Glad the vid was helpful! One other aspect that may be helpful is knowing that many of the Unison amp sims are in the 1M Ohm range. As a result, using a DI with 1M input impedance and the amp plugin in the insert slot will get a similar result.

@@MattHepworth I checked my manual and the quad has a 2.2M Ohm HiZ ..... My Great River Pre's HiZ is 1.2 M Ohm, w additional loading options. close enough? Thanks so much for your help!

I love my Great River pres and they have great HiZ ins, too. I think you'll be happy with the results. Won't be identical, but will sound great.

It really depends on how much you'll be using the amp sims. All other Unison functionality (mic preamps, etc.) are identical. I personally use two Silverface Apollos.

Not if your a good mix engineer. However, I do dig the true unison flavor!

I'll let you know. I believe that's the case, though.

So Josh, meter should work with Unison initiated. In my testing it looks like it's the ACTUAL level seen at the Unison plugin input (post hardware/impedance changes, etc.), not the level at the Unison's output, though. Since this hardware interaction may pad down the input, you might not see much level compared to what your meter in Console will show. It may also be helpful to know that Apollos all meter pre-fader, so to speak, on the hardware. It's not affected by plugins inserted. Unison is the exception because it affects the input level directly.

Edited the above for clarity.

@@MattHepworth that is basically what uad told me a couple days ago also , Basically the meters are only showing the input signal aka my guitars pickups signal . Which is good I guess if using boost pedals before the hiz as to not clip the input . It would be cool if one could switch to monitoring the input meters to monitoring the output for when setting levels , but it’s fine . Thanks for getting back with me , have a merry Christmas!

@@MurdaMetz You as well, thanks!

Great question! Yes, the difference is strictly Unison, in this case, as the Twin (mk I) has the same converters as the Silverface rack Apollo.

Thank you :)

It's not night and day for sure. I've recorded many great takes through my non-Unison silverface.
