Networking it together for Diamond

Each of the 70 Crown Macro-Tech 5000/5002VZ house amplifiers supplied by Maryland Sound Industries (MSI) on the Neil Diamond "Mission of Love" tour is equipped with Crown's new IQ-PIP USP2/CN CobraNet module USP2/CN card.

This allows digital audio signals sent from the Yamaha PM1D FOH console through a CobraNet converter and BSS ProSys PS-8810C to be fed directly into the amplifiers on Cat 5 Ethernet lines and switches. All of the processing for the production's JBL VerTec line array loudspeakers - including crossover, delay and EQ - is performed by the Crown modules.

Using a laptop, the PS-8810C DSP system is wirelessly called upon to compensate for differing room environments each night, leaving the Crown USP2/CN cards within the amplifiers to specifically address speaker processing.

The ProSys unit further allows each of the JBL loudspeaker clusters to be grouped as single signals, and both the BSS and Crown products are controlled via Crown's IQ for Windows software v5.0, which provides a unified interface whether adjusting an entire cluster or just one driver.

"Because our sound system this time around is entirely digital, it's dead quiet; the noise floor is extremely low," says Stanley R. Miller, Diamond's sound designer and chief engineer for live sound. "We've not had one single solitary problem with buzz or hum - something we used to spend an hour or two each day on previous tours trying to chase down. Overall, this rig sounds hands-down better than ever before, and there are a number of reasons for that, not the least of which would be Crown's new CN cards.

Miller called upon Sam Helms of Manalapan, New Jersey-based Sigmet Corporation to help provide the system design. "When Stan told me over a year ago that he wanted the system for this tour to be totally digital, I had some initial concerns regarding the potential tradeoff in sonic quality; I was worried that it might be a bit tinny or brittle," Helms recalls.

"But when we finally pieced the primary components together and first fired it up at MSI, we were all absolutely floored at the difference. The Crown USP2/CN module really showed off the attributes of the JBL VerTec loudspeaker. The vocals came right out of the box and the instrumentation seemed to be separated within the cabinet. There was hardly even any need for EQ. Then we A/B-ed it with an equivalent analog setup using a Crown USP2, which is an exceptional tool in its own right, and the difference was night and day. The detail we had achieved by going the all-digital route with the CN module was breathtaking."

MSI has been contracted to provide sound reinforcement using the current SR system -including the Crown gear - on all of the overseas dates as well.
