    QSC TM30 recording issues

    It is not uncommon for USB multitrack and USB computer connection to be mutually exclusive (this is also the case on the A+H SQ series, for example), although QSC isn't as explicit about that behaviour in their documentation as A+H is.

    B&C DCX464 vs DCX 354

    B+C has some recommended DSP settings for the DCX464 used on their horn with their passive crossover as part of their 215-DCX reference design ( https://www.bcspeakers.com/media/W1siZiIsIjIwMjIvMDgvMTEvMDhfNTNfNTdfNDExXzIxNV9EQ1guemlwIl1d ). And it looks like the passive crossover uses a 3-pole...

    Presumably, it's an https://en.wikipedia.org/wiki/ALCO_RS-2 That unit, of course, handles sequencing completely independently of the Surgex unit.

    Which set-up for a Monitor desk set-up?

    More faders is more better if you've got the space, IMO, so I'd generally prefer option 2 here. Also, patching is generally happier if it's not split between IO devices.

    Are Altman bases way more expensive

    I don't have pictures, and the shop that had them has since closed down and I suspect the steel was recycled. But, some ASCII art: Side view | | /| |\ / | | \ ---------------------- Top view ---------------- | | | | ----O---- | | / |...

    Are Altman bases way more expensive

    I suspect that when Altman moved their shop from Yonkers to Denver in 2020, their supply chain changed a bit. If you don't need to stack the bases, I've used some shop-fabricated units made from plate steel and 2" pipe (the 2" pipe is a socket for the 1-1/2" pipe, and a pair of bolts locks...

    Working with other peoples scenes

    Heck, I've even been burned by my own scenes (workarounds for system issues that ended up stored in the scene, but were fixed properly later). At this point, I'll almost always start with a template scene of some type, but not a scene for a specific act. For the venue scenario where there are...

    Correct feeder cable for distro

    If you have ferromagnetic material near the cable, you will get current flow into that material due the the changing magnetic field. That current circulates and can cause heating of the material. This is the "eddy current" phenomenon, and is how induction heating works. This is a cause for...

    Correct feeder cable for distro

    An induction heater isn't going to heat anything that doesn't allow current to flow, because the "induction" in that device is "induced [eddy] current", and not "inductance (the tendency of an electrical conductor to resist the change of current)". Only the resistive (real) component of the...

    QSC touchmix 16 no longer recording - help

    The easiest way to determine if the problem is with the Touchmix, the SSD, or the cable between the two, is to swap the SSD with a different drive (SSD, hard drive, or even a USB flash drive should be good enough for testing). This will allow you to determine if the problem follows the SSD, or...

    Why are the x32 & M32 products only available at Sweetwater?

    The couple of online dealers I checked appeared to have dropped all Behringer and Midas products (although other Music Tribe brands don't appear to be as widely affected). So not limited to the x32 and M32 lines

    Micing tabla for maximum volume

    If the tabla are between the foldback and the player, I'd be tempted to try a bidirectional mic between the two drums. Both drums are in pattern (although note that the one on the back side of the mic is polarity-flipped) and the foldback ends up in the null.

    50a RV power hookup

    If your rig is set up around running from wall power, a spider box or the Lex equivalent is going to be your best option. Readily available for rent (with the feed cable) if you'd prefer to go that route, or available for purchase with an NRTL listing on the box. Only drawback is that you'll...

    Best option for 12" Box Truss

    Last time I was playing with 12" box truss, the 2 big players (really, the only stuff with significant rental inventory in my area) were the bolt-style Tomcat and James Thomas Engineering (usually just abbreviated to "Thomas"). The two could be bolted together with no issues, and were often...

    250 cap venue for "bass heavy" music... will a 2x18 do it proper?

    Despite what many people think, it _is_ possible to get a decent rock mix on a rig with no subs. You will, however, need to think a bit more about how you manage the mix. Things like a HPF on the kick (take the thump up an octave, a bit more click), and letting the harmonics of the bass guitar...

    Passive Wedges - what good ones are out there?

    Have you looked at streamlining your stage setup for powered wedges? I've worked small stages with both types, and I haven't found passive wedges to be any quicker than powered wedges, especially once patching amp racks and running stage power are taken into account. FWIW, my preferred setup...
