The Opus-Two Instrument Control system has several unique features that make it the most flexible control system on the market:
- No card cages (no backplane boards, excess cards, wasted cost, wasted space)
- No computer cores (no computer power supplies, memory, custom PCI cards to fail)
- No expensive engineering fees for special requirements
- Not dependent on any external hardware (the system is self contained)
- Consoles and chambers use the same hardware. Multiple console and multiple chamber support built in, requires no extra hardware.
- Does not use Ethernet networking, eliminating concerns of packet loss and latency and poor connections over time.
- Fiber Optic Links available for lightning-prone environments.
- VERY low latency (under 20ms).
- Does not rely on MIDI for inter-system communication, yet has full MIDI I/O compatibility in all locations.
- Used in countless church organs and theater organs.
- No power needed to maintain memory (no wall-wart style transformers needed).
- Any installation can be made larger or smaller by simply plugging/unplugging cards and updating the configuration file.
- Adding additional manuals, stops, pistons is as simple as plugging them in and updating the configuration file.
- Additional chambers can be brought online by simply connecting them to the high speed data bus supplying other chambers. No console updates needed.
The Same Equipment Used In Console & Chamber
- All Opus-Two Controller, Input Cards, and Output cards have an 8 pin connector at either end, allowing plug-together card chains.
- Each chain is typically started with a Controller card, and consists of a controller card and at least one input/output card. The cards can be plugged in any order.
- It is quick and easy to wire from one “row” of cards to the next (using supplied CatAdapters).
- Each input/output card has a power, fused power, and two ground connections.
- The exact same controller cards, input cards, and output cards are used in the console and chamber. The only difference is in the programming of the controller. This reduces the number of spare parts to have on hand.
How It Works
- Each unique location (console, chamber, blower starter, etc.) has a controller card. Each controller card has a 3 wire header, and they are all connected together (high speed data bus). Sometimes old wires are used from a previous system, sometimes Cat5/Cat6 cable is run.
- The console will scan/read all inputs, and generate a ‘frame’ containing a complete console status (swell shoe position, stop statuses, and key statuses). This frame is transmitted on the high speed data bus. Any additional consoles will take turns transmitting their data.
- Chambers will receive this data, process it, and generate appropriate output to the attached output cards.
- The process is repeated.
