Can the ARC-PS be used with Integrator Series devices (722, 760, 780, 788)?

Yes.  Simply connect the RS-485 ports of the ARC-PS to the RS-485 port on the Integrator Series hardware.  No special programming is needed.

ARC Power Calculator

An ARC’s power requirements vary depending on the voltage supplied to it. For example, an ARC-2e at 24V DC uses approximately 55 mA, while at 7V DC it uses approximately 170 mA maximum. As the voltage varies from 24 to 7 VDC, the current requirement increases accordingly. ARCs can be daisy-chained and fed power over this daisy-chain from an ARC-PSe or other device. However, as the length of the cable increases, so does the resistive line loss, which lowers the voltage available at each subsequent ARC. The actual power drain on each output from the powering device can vary substantially depending on the number of ARCs and the distance each of them is separated by. In order to assist with system design, Symetrix has available a Microsoft Excel spreadsheet that can help a system designer determine power requirements based upon cable length, number of ARCs and the power supply to be used.

What direction is ARC-Audio sent?

One channel of audio can be sent either way.

What is the ARC-PS?

The ARC-PS is an 8 port expansion hub for data, power and ARC audio.  The ARC-PS is supported by all host DSPs.  Note, some DSPs may require a special cable.  Contact for more information.
