avassets AVIOM 6416M MIC INPUT MODULE By Shawn Parr viom’s Pro64 Series offers a modular approach to building digital snakes for almost any event, large or small. Adding more I/O or multiple digital splits is as simple as plugging in a Cat-5 cable. The new remote-controllable 6416m mic input module provides 16 mic-level analog inputs to a Pro64 system. Each channel features continuous gain control, +48V phantom power, low cut filter, phase invert, mute, and a Network Activation button. With a switchable pad per channel, the 6416m also accepts balanced line-level inputs. THE PROS The Aviom Pro64 snake system is incredibly easy to use, deploy, and work with. Students already versed with audio technology and analog snake systems can be taught to set up and use the system in a matter of minutes. In its default setup it literally manages itself. As long as you can keep track of channel assignments, you can use the system. One can use inexpensive and easily available Cat-5 cables to move parts of the snake where they are needed with much less concern of concealment and trip hazards. THE PRODUCT: Aviom 6416m mic input module for Pro64 Digital Snake System THE MANUFACTURER: Aviom, www.aviom.com THE PRICE: $7,500 U.S. list WHERE TO USE IT: Live corporate events, houses of worship, musical and theatrical productions. A THE CONS Some students had issues with power supply cables coming loose. Having a clamp to hold the cable (as many console power supplies have) would have been a good idea. Also, a firmware upgrade (which was one of the first things we needed to do out of the box) requires re-setting many of the dip switches. It is a proprietary system, so if you have an existing data network you will need to install a second network just for the Aviom system. THE APPLICATION Our first use of the full system was for a campus production of You’re a Good Man, Charlie Brown. We had to locate our front of house (FOH) mix position on the orchestra pit, with the orchestra upstage center and our amp racks in a booth at the back of the house. We used a 6416m mic input module with the orchestra for the mics, a couple of 6416i linelevel input modules with the wireless racks, and a collection of 6416i’s and 6416o’s at FOH and in the booth to route audio back and forth. A traditional snake system would have required the use of several snake systems, or a complicated setup with multiple transformer isolation systems. THE RESULT Each production at the university has a unique setup. Several theaters with differing layouts and different production styles keep us hopping. Sometimes we can use a very traditional system, with an FOH or booth control system, orchestra in a pit, and mics backstage. But often we have to support productions where the audience is on stage with actors, and unusual FOH and orchestra locations and layouts, all with our DSP and amplification handled from a control booth. The Aviom’s flexibility and self-management features allow us to easily and quickly adapt to these situations. During the installation phase, for the nominal the cost of Cat-5 cable, we were able to ensure that a Cat-5 drop is available at multiple locations throughout the main theater and house, with an MH10 merger hub in the control booth to tie the whole system together. When working on productions in a smaller space, the system allows for fast and effective ad-hoc network setups.
