ON-SITE SUPPORT

When the visiting programmer flies home after opening, we stay for the run. Same time zone, same building.

All That Story

RELIABILITY

Every station runs two of everything.

Two workstations, two audio interfaces, and a passive automatic switcher between them.

A second screen so the operator sees both machines at once.

Power arrives through an AVR and a UPS before it reaches any of it.

If the primary dies mid-number, the audience does not hear it.

The Seoul run of The Great Gatsby (2025) completed without a single system failure.
