LS9 Routing - Mix bus to channel input?

Recommended Posts

Hi all

 

I'm having trouble with routing on an LS9 - I'm trying to sum 10 channels together and route them back through a single fader. I've summed then on a mix bus, but I can't find a way to route the bus back into a channel on the first layer so it could be routed into the main mix. On the O1Vs of old it would be available in the input routing, but on the LS9 I only seem to have the ADs, the slots and the 2TR inputs available.

 

I could route out of an omni out and back into an AD (or via the SPDIF) but it seems messy if I can do it internally.

 

Thanks in advance

Hi there,

 

there isn't a way that I know of for routing it back to a channel...

 

But if you use the custom fader layer and just have that mix bus master fader on there that'd be a way round it... just route the mix buss straight to the L/R etc

 

And if you use 2 mix busses to have a stereo pair, you only need to display 1 mix master on a fader as they are linked so you can fit even more faders on the custom layer...

I could use the master fader on a custom fader layer, but I think I'll probably patch through the SPDIF to achieve this. Can you route back through the mix buses from the master fader section or just to the matrixes? As I'll want some post-fade Auxes from this channel as well.

You can't route the mix masters back to mixes no... Having looked at the LS9 in front of me now! Only to the matrixes as you thought...

 

So your idea of routing it back out of the 2track out and back in again to a channel would work... I don't know how much delay it would add as I've never measured it... Shouldn't be noticeable though hopefully... But that would get you all the post fade aux action you required etc

If you've got a spare effects block, you might be able to do something creative there - insert in the bus but return to a channel insert perhaps? I've not got the desk in front of me right now but I'm sure I've done something similar in the past.

I'm not trying to adjust the mix level - I'm trying to route back though an input channel to route in turn to other mix buses. It's to sum some mics together and have collective control over their levels to both FOH and a post-fade aux.

 

I'll look at routing it though a bypassed effects unit, you should be able to route bus outputs into an effects until and output via a channel input, with full routing capabilities - as described.

 

Am I right in thinking you could do this straight from the channel input patch on the 01V/O2R/DM series? I'm sure I've done it in the past.

can you not channel link the mics together? Say its 10 channels you link them all apart from say the HA, then you can put ch1 on the custom fager layer and anything you do to ch1 is repeated over all ten whther it's moving the fader or sending to an aux.

No - I'll still need individual control in addition to the 'all mics' fader. It's something I'm trying for chorus numbers - we've got ten radio mics on stage, along with a live band, and for inidividual soloists the pickup is fine, but for chorus numbers the coverage is a bit thin. I'm mixing the thing on the fly so I'd like to try out a single fader for all ten mics for the large chorus numbers, so I can try and use a little of the principles just to pad out the ambient mic'ing.

I reckon the bypassed rack unit is the neatest so far if it works, but it would allow me to take individual channels out of both mixes with the 'Channel On' buttons. None of the EQ etc of the original input channels would be in the summed mix if I split the inputs.

unless im missing the point here, you link said channels togther (1-10 FI) then custom layer add fader 1 to custom fader, this controls all levels relative including post aux levels.

 

Then if you want to adjust said levels, as shez says, hold down select, adjust fader level, let go and it travels with rest of faders.

I really want to have all ten available, and an eleventh which has all ten summed together. With that solution I'd be holding down Select for the majority of the show, which isn't ideal. I could route the ADs to ten faders on the second layer and link them instead but that still isn't ideal, although it's better.
