Technical information for The A & B Amphitheater

Technical Specifications

STAGE INFORMATION:

Stage Canopy:
The stage area is covered by a 66'W x 32'D white free standing structure. The structure has a peak roof, with a center height of 21', coming down to 12' on the ends. There are side flaps that can be closed on three sides, in the event of inclement weather. The tent protects the stage from most weather conditions, however the stage is usually in direct sunlight from around noon until around 6:00 PM. The canopy is erected on a concrete slab that is approx. 2' higher than the lawn seating area. For structural reasons, nothing can be hung from the tent. Please see drawing for additional dimensions.

Staging:
The concrete slab that serves as the basic foundation is approximately 2' higher than the lawn seating area. A portable 2' stage is then erected on top of the slab, making the final stage height approximately 4' higher than the lawn . The portable stage is manufactured by Stage Right Corporation, and consists of 4" x 4' x 8' decks on top of heavy duty "Z" type legs. Dimensions are 36' Wide x 24' Deep. The stage is carpeted with a gray industrial style carpet, is skirted, and has the appropriate stair units available. On stage risers are available upon request.

Monitor world, guitar land, or other offstage areas don't need any staging, and can be set-up directly on the slab, 2' lower than the main stage. Front of house area is 100' dead center, and is built on an as needed basis, but generally works out to a 12'W x 8'D x 1'H platform for sound, and an 8'x 8' for lights. Spots can be placed on slightly higher platforms, or scaffolding can be brought in for an additional cost. A FOH tent is optional.

LIGHTING:

As mentioned before, MACC contracts all shows with local vendors. Lighting rigs are built on a per plot basis, however there are severe limitations. Because the stage is under a low canopy, trim heights can be a problem. Front trusses can be 40' & fully loaded to the capacities of the ground support equipment. The front truss is actually outside the tent, so trim heights can be maximized, however final trim height between the bottom of a can, and the deck is usually around 12'. The upstage truss is more of a problem, because it needs to be inside the tent. The optimal configuration is a very short (12' to 16') truss or pipe with underhung rows of lamps. The wider the truss, the lower the truss. Designs that incorporate side trees, or floor lights may up the lamp count more efficiently. Be aware that most shows end up with around 60 lamps. Certainly more can be done, but big rigs are costly, and don't fit very well anyway.

BACKDROPS:

Cycs, painted drops, screens, or other full size backdrops should be left in the shop. Don't even try it. The potentially windy environment, coupled with the fact that no load can be added to the tent, make it a difficult and unsafe proposition. However, the tent is completely white, and used properly, with the right lighting and a little creativity, can be attractive.

SOUND:

There are a few good local sound companies in the state. Most are capable of any size production, and can supply backline equipment as needed. For smaller shows, smaller systems are available. Set-up is straight forward. FOH & wings are discussed in "staging" above. Underground conduits for pulling snakes are in place. There is a 103dB (A Weighted), sound limit at the console. Measurements are taken, and printed out for inspection at sound check.

POWER:

Power is good & clean. There is a 400 amp 3 phase lighting disconnect, and a 200 amp 3 phase isolated ground disconnect. Both panels are located about 20' from the upstage left corner of the tent. All connections are large camlock style. Connections need to be made by a house electrician. There is no shore power, but if you can get your bus here, we'll hook it up.

BARRICADES:

When a barricade is required, it is constructed of freestanding wooden 4'H x 8'W panels. There is enough room between the barricade and the concrete slab for pit security. When no front barricade is required, barricade material begins at the downstage edges of the tent, and wrap around the wings to the upstage, leaving the front of the stage open.
