Welcome to Sound Decision Productions

2025 is well under way, and all of us at  SDP are thrilled to be a part of Milwaukee’s Zoo Ala Carte and Bastille Days for another year! Both of these 5 stage festivals have been around for decades.  Jazz in the Park, Live at the Lakefront, Summer Soulstice, Watertown Riverfest – are just a few of the summer festivals that SDP will be providing production for once again!

Looking forward to the Christian events this year!  Excited for year two with the fundraiser – “Beats for Heartbeats” once again! SDP did quite a number of Christian acts this past year.  Artists like Chris Tomlin, Amy Grant and Unspoken.   You might remember last year mentioning Unspoken’s production manager Ryan Mohr telling me that the Coda AiRay system was the best system he’s heard in quite a while.  Chris Tomlin’s front of house engineer Steven Bailey was also impressed as he went on to say“AiRay proves that size and weight are no longer requirements for a world class PA.” 

In 2023 I had made the comment – “Maybe a Christian tour in our future….?”  As a matter of fact, in January we did do a small “tour” of a few northern WI as well as MN shows with the Christian band Koine.   Would love to do more of that!!

Milwaukee’s Chasin Mason will be using SDP for a few upcoming reunion shows.  These guys are personal friends of mine, and I am  proud to be a part of the excitement!   

Cheers for now…

~ Mark Hartzell, CEO of SDPEvent

SDP in 2025 - Raising the bar even higher!

2024 – another record year for SDP!  Mid year we picked up a substantial inventory of new Coda gear.  20 ViRay cabinets, more SCP subs and Linus 14 amplifiers.  ViRay is the little brother to AiRay and has the Coda clarity voicing that we’ve come to expect from Coda.  It is great for smaller duty, as well as for underneath AiRay.  It worked well in the Arena setting, as well as the  Stone Temple Pilots / Collective Soul Lambeau Field concert this summer with  20,000 in attendance.  Good Stuff!

Call us today to see what we can do for your event!

SDP Rocks out with Jake Owen at Lambeau Field!

Bill Danilczyk and Stephen Swope on site from ESP, who provided additional Coda gear as well as the Linus control programming- making the setup day a breeze. SDP’s own Paul Leitner, who’s setup talents (and great job mixing the opener) helped make this day a success!

We used a “splayed end fire” sub array for the project.  With such a large coverage area (350′ deep by 650′ wide), we needed a lot of sub energy – but not on the stage.  The splayed end fire configuration not only kept the LF off the stage, but spread it out over the whole listening area quite evenly.

Coda gear used – 46 AiRay, 8 ViRay, 24 SCP-F, 12 SC2-F, 24 Linus 14D amps.
