When technician had to find a new PA for Bendigo’s , he did a full dress rehearsal.

The was built in 1873, as a masonic hall, when the big Corinthian columns and Octastyle porticos of the Renaissance Revival were in vogue. The cement rendered building is ornate, and it looks brilliant, so good that it has a dreaded heritage overlay.


Nary a hole can be drilled or lick of paint applied without attracting unwanted attention, so when it came to choosing a system, it had to be able to hang off the existing front truss. It also had to come within the budget, and handle a huge variety of performances from Fred Astaire tribute acts for retirees to indie bands travelling through the region.

When some capital funding came the Capital’s way, Levis knew he didn’t want to make the decision in isolation. He founded Troy Horse in Sydney and has a long history in event management and audio installation. “It’s very hard to make a decision in your own venue; you know too much about it,” he explained. “We wanted to get closer to what the clients coming through the theatre, and the punters in it, experience.” He invited other technicians, local theatre and hire companies to be part of the process. He then put out a call for any distributors who wanted to be part of the shootout, coming out with a handful of high quality PAs that fit under the budget ceiling.


Levis wasn’t content to simply pump out a playlist of program music, “the majority of what we do is live performance, so we put live music through it,” he said. “We had a local guy called come play some acoustic blues, then some material with a full rhythm section. Then we got a guy to talk at a lectern, ran some theatrical sound effects and, of course, played program through all the systems, too.”

Throughout the day, no one knew which PA they were listening to — Levis would alternate between them in random orders — or what price point each came in at. “Gradually people narrowed down to a couple of systems,” he said. Everyone took notes and they went across to the pub to chat about it. The next day, a smaller group of technicians returned to the theatre to find out which PA was the easiest to pull a mix on. “I was very concerned about making sure people got hands on with mixing through the systems,” said Levis. “I figured if more technicians could pull great mixes through it, it would be better for everyone.”

With all the feedback and written reports, Levis was worried they’d get a spread of favourites. However, he said it was almost unanimous, everyone loved the sound of the rig. After showing the rig to management at the end of the process, they were pretty happy that it also came in at $35,000 less than any other contender.


The system now installed at the Capital is a pair of KV2 Audio ESR215 full-range, three-way loudspeakers. The five-foot tall box has two 15-inch woofers, above and below a central three-inch compression driver and eight-inch, horn-loaded mid-range driver. With its 110° dispersion and centrally-located mid and high drivers, it works best flown where the top end can spread out rather than hit you in the stomach in a ground stacked setup.

It pairs with the control device containing six individual amplifiers with separate Class AB topologies to match the components each it is driving. System processing is via a Super Analogue Controller — which has basic controls for limiting, a four-band EQ and a couple of notch filters — and two Delay Lines. There’s no DSP signal processing to mess with, which fits into KV2 Audio’s philosophy of building monitoring-quality loudspeakers that don’t need intervention. Despite the tri-amplification, it all goes to the box on one cable, which suited Levis’ heritage-restricted working environment just fine.

While the ESR’s go down to 30Hz, the system also has two subs mounted under the stage to reinforce the low end. They’re driven by a separate amplifier.

Three perfectly-timed front fill speakers are embedded into the stage, which Levis can pull up on top of the stage to get a bit more throw during a band show. The whole system sounds fantastic, and gets great coverage across the venue without the sense of losing one side as soon as you step off the centre line. Front to back, with the seating rake, you only lose about three dB, eliminating any need for delay speakers. It’s a testament that sometimes flashy line arrays, with loads of processing and Class D amps aren’t always the best solution; point source boxes tied to a Class AB amplifier can still sound spectacular… and apparently can come in much cheaper, too.
