So if I was to add a AR2412 to my Qu-SB, I’d get:
— 16 extra mic pre inputs
— I could map another 6 XLR’s as stereo inputs corresponding to St-1-3
— Leaving 2 XLRs spare

How many of the AR2412’s 12 output channels could I use?
EG, for IEM pairs?

Andreas,
That’s a shame, but thanks.

[GaryWParticipant]

I have a Qu-SB, and using local inputs

[GaryWParticipant]

Barryjam,
No, not possible.
The clearance with that SKB shallow rack is only just enough for the Qu-SB without cables.
That said, I used right-angle RCA to TS adaptors for the Stereo-1 inputs, those I can leave plugged in.

Very much enjoying the compact size of the Qu-SB mixer plus iPad combo!!

I have a Furman power conditioner mounted in the rear of my SKB shallow roto rack, plus a 1U power strip with 6 x power sockets, as well as mounting my Airport Express and Ethernet to DMX bridge on the rear.
It’s all a bit of a tight fit, but it works.
The rack case is now nicely balanced and pretty much everything is pre-wired and ready to go.

[GaryWParticipant]

I’ve just ordered the SKB 4u shallow roto rack, I didn’t check clearance…

[GaryWParticipant]

Ok, thanks.

[GaryWParticipant]

Yes, I’m getting quite adept at hitting ‘Home’ and ‘Meters’ to check what’s going on. But I do miss having an always on summary visible at the top of the screen.

[GaryWParticipant]

Thanks Mervaka,
Yes, I agree it should be, but with closed box active speakers it’s hard to know what has been allowed for and what hasn’t.

From my own speaker design days, I know that a vented speaker rolls off at 24dB/octave because the output of the vent is 180 degrees out of phase with the driver, thus cancelling any in-cabinet air ‘suspension’ for the driver and therefore rendering it largely undamped below the -3dB point.

As a safety when using an active vented design I always opted to add in a low cut just below the lower of the two impedance peaks to protect the driver from going into dangerously large excursion territory. While the amp would be fine, the cone could shred itself if driven hard.

My personal preference is to protect my subs just-in-case the manufacturer cost-cut that option out. If I could do that at the LR or Monitor output it means that I can bypass the need to add in a speaker management processor.

[GaryWParticipant]

Hi Giga,
Unless I’ve missed something, the PEQ on the output channels gives me a variable width notch filter, or a rather broad shelving filter (by moving the ‘width’ slider extreme left).

I could combine a low cut shelf with a moderate Q boost to in effect shape the cut to give it a steeper slope… but it’s not as effective as the option to add say a Butterworth 6, 12, 18dB/octave or a LR 24 dB/octave cut.

If you wanted to do a quick sanity check, route pink noise thru a monitor (at low-ish volumes!) and use a good RTA app on your phone.

On the Qu-Pad app, Setup->Audio->SigGen, then Pink Noise and select output channel.

Of course, SMAART at the high end and the free REW would also give you similar results.
