How was your PA last night?

Last night ... " well saturday" ... our PA failed , We had to spin our  Monitor round and crank it to make up with it ... as a Fully ampless band this was a bit of a disaster.

The right side of the Mackie Industrial  ART 200A  would not transmit any sound from the main speaker ...  the Horn/Tweeter was producing sound confirming that  it wasn't a power issue or a mixer send issue , I confirmed  this swapping it and in my post mortem testing sunday ... when i cracked it apart hoping to find a simple issue like a loose terminal connection and within my cack handed ability to mend.

Sadly is seems one of the EQ block's is soggy / rotten 😐

Annoying ... but we've had to rush order a new EV PA ahead of next weekend's gig , the band voted with their wallets after being let down by used gear.

 I have found the circuit diagram for this speaker, and it uses fairly conventional analogue circuitry.  It is not a high-powered speaker, using three LM3886 amplifier chips, two for the LF and one for the HF. I have to say that Mackie run this chip very close to its maximum voltage unless the LF speaker is 16 ohms. Happy to have a look at it if you like. IMHO, useful as a monitor, but not FOH.

I went for the TS312s on foh and 310s for monitoring. On larger gigs we add a 312s sub.

That's the same setup I used to have (except for the 310's). It's a great rig for the price.

I eventually got hold of a 315s as there was a b-stock item going for a ridiculous price (£120 off the top of my head). It's good, but definitely not as easy to move around as the 312s.
