H90 output both stereo and mono?

[carl_stanley]

all –

is it possible to setup the H90 so that it outputs a mono signal on Output 1, and a stereo signal on Outputs 3-4?

I have it in my bass pedalboard (which is mono) but want to take a stereo signal out to the PA as well.

If this isn’t possible can this be added as a feature request?

thx!

No, this is not possible. If you only connect out of Output 1 the H90 automatically functions in mono, even if you were to use the stereo insert last in the chain.

If you will not be combining two algorithms per program, the workaround is using Dual Routing Mode and spitting your signal before the H90. Feed one to Path 1 (mono) and the other to Path 2 (stereo). Use the same algorithm for both.

Joe –

thx for the reply!  follow up question – lets say I have a device that connects to stereo out on H90, it has stereo out passthru and a summed mono signal out (all buffered), something like:

 

H90 output L –>  Device –> L out

H90 output R –> Device –> R out

|

mono summed out

 

Do the H90 algorithms  change depending if its mono out or stereo out, or does the H90 just sum the 2 channels for mono?  Would something like this work or would it have phase issues that a H90 mono out  signal doesn’t have?

thx again!

Having the H90 function in mono naturally by only connecting Output 1 is always better than having an outboard device sum for you. The algorithms are designed to adjust for optimal performance when appropriate connections are made, and they have no way of detecting an external sum mixer. That said, in most cases, you will be okay summing externally, as in the case when your running a stereo rig but you can only connect in mono for a show or something. I’ve done it. Nonetheless, ask the pro rig builders and 100% of the time they will tell you, connect things in mono if that’s what you want, don’t sum externally.

Thx Joe!  Your explanation makes total sense – thx for the quick reply!  (now to find such a device, i dont see anything like it out there – i think i’ll have to build it myself)

[joecozzi]

Are you referring to a summing mixer that sums a stereo signal down to mono? There are plenty of boxes from Goodwood Audio (Output TX), JHS (Summing Amp), and Walrus Audio (Canvas).
