I swear I have seen Alcon in the gear summaries in LSI.

Know nothing about them.  So many good comments.

By the time you power them,you could get FBT or DB Tech boxes that have support,  a dealer channel and published performance data.

I would also be curious on a comparison between DZRs and JBL SRXs.


One thing the SRX-p has over all these boxes in this league is larger format compression driver - 1.5" exit with a 3" diaphragm behind it. That was a major reason why I chose the SRX over anything else out there at the price point. It's going to have more upper mid/high frequency grunt with a true medium format compression driver. That may not be what many need, but it's going to cut through better on loud stages for monitor use and have better throw outdoors compared to a 1" exit driver with a 2" or smaller diaphragm. Seems the lower end boxes these days are going down as small as a 1.4" diaphragm which is not what I'm looking for. Given my druthers, I'd have boxes with a 2" exit compression driver and 4" diaphragm. But that's a lot more $$.

Must be quite a lot of buzz to get past CMR on the mic cables...

How are your connectors terminated? Do you have the shell terminated to pin 1 or is the shell floating, have you tried it the other way?

Does your cables have a braided shield?

You say that you encounter this issue with multiple consoles so I doubt that there is any issue there.

I've had similar issues with mics on random stages, cable test as correct with MM and cable tester yet is buzzes, swap out cable with another and it is fine so I just end up retiring the cable.

regarding switch mode power supplies, I know HAM radio guys hate them because of the RF they spew out, very few have correct PF correction and RF shielding and even then the only place for the RF to go when it is shielded is to the ground connector.

I would check impedance to ground on your distros as well, this is a test probably best done by a decent electrician but may actually reveal your problem, could be some corrosion on a connector or something causing a higher than normal impedance to ground.


The shell is floating. As shown in the video, the issue clears when the exact power cable is plugged into an EV powered speaker. There is no signal cable plugged into either speaker, so the noise is self generated and not related to a ground loop. The JBL is the noise source. Mic cables in this test are new Whirlwind MK4 series which are good cables: [size=78%]http://whirlwindusa.com/catalog/pre-wired-cables/microphone/mk-series[/size] . But it also happens with Canare quad mic cables. This issue occurs with my distro as well as non-related power in more than 1 venue. It's not the power. It's not the mic cable. It's not the console. I'm waiting for an order of ferrite beads to arrive to see if that mitigates the issue. I've tried reaching JBL support to discuss the issue several times this past week and have received no response yet. Their customer service so far is disappointing.

Been there done that... the UL standard for the cheap 3 light outlet testers was a few hundreds of dollars... (I don't recall the exact amount because I'm trying to forget it) and you can't quote from or share copies of it.

PS: Not to mention that my tester covers things that the standard does not describe, so that would cost me even more money to get them to add new stuff to their standard. ::)

The typical way to prevent fouling of the cable on the drum is with a tensioner that amounts to a plate that applies pressure directly against the rope already on the drum. That also prevents the drum from freewheeling.

To ensure that the rope is neatly laid on the drum, a device called a level wind is used. This is a guide that rides on a double-counter-helix screw that is mechanically linked to the drum; as the drum turns, the guide moves back and forth, neatly laying the rope on the drum.

I've never seen a level wind on small hand winches (but high-end fishing reels have them!). My "come-along" has a spring steel tensioner to resist fouling, but it isn't a perfect solution.

(Maybe you know all that, but I didn't see it in the discussion.)

My biggest concern beyond amp, deployment, ROI, etc. is the rigging. I'm leery of a no-name budget Chinese system that will be hanging in the air. Who knows what the quality of the steel is and how well it's engineered. At least with any known brand, even lower end stuff, you can be fairly certain the rigging hardware is safe to fly over humans before a know brand puts their name on the product. This kind of thing scares the crap out of me.

I was hoping to do a comparo between the DSR and DZR, but I ended up selling all of them before I had time to do that.

Thanks for the info but it makes more sense to compare the DZR to the DSR, because the DXR are in a lower league.

I'd rather have the S31 than S21 - not much more money for a better (larger) surface. 

The SQ7 has great sound, wrapped in an OK interface. 

If it were me though - I'd look most at the baby DLive options.  CDM rack(s) and C3500 at FOH, maybe start with C1500 or even software only control for broadcast. 

SQ7 I would rate as the best of the entry level options, the S21/S31 mid-level, DLive high level, with the large Digico and SSL as top.

I second this recommendation as the DLive architecture is a higher end platform you won't outgrow and provides interesting capabilities for churches.  For example, if you don't have the staffing, funds, or talent to mix the broadcast feed (as opposed to taking raw FOH mix out) you can provide capability for an easy submix in studio that takes FOH groups such as band, vocals, pastors, playback and allows someone with minimal skills to mix that with audience response during message or balance rough levels to fit broadcast.  Can easily grow into full split mix on iPad and then surfaces.

I'm personally over S21/S31 as Digico is putting all their effort in the SD touring consoles IMHO. They sound good but feature set is severely lacking at this stage in development.  Built-in FX library very limited, no de-essers (yeah limited multi-band),S21 bank scrolling, no channel libraries...I can go on forever.

Good luck!
