Applying Power - AMX Precis DSP Instruction Manual

Installation & Setup

Applying Power

The enclosure's universal power receptacle will accept all major international standard power sources.
A standard US power cord is provided for installations within the US. Maximum power specifications are
on the power receptacle (also listed on page 9). Always use an earth-grounded power cord / system with
a Precis DSP.
The source electrical outlet should be installed near the Precis DSP, easily accessible, and properly
grounded. Power should come from a building branch circuit. We strongly recommend using a dedicated
line for the system's power. Use a minimum breaker current rating of 15 A for 110 V or 30 A for 230 V.
To avoid an overload, note the power consumption rating of all the equipment connected to the circuit
breaker before applying power.
Caution: We recommend attaching all power cords to a surge protector and/or an AC line
conditioner.
Power-Up Sequence
To apply power:
1. Attach the first two source and destination devices; see page 15.
Do not apply power to the source and destination devices until Step 5.
2. Plug the power cord into the power receptacle on the enclosure.
3.
Plug the other end of the power cord(s) into a power strip that is turned off (we recommend using
a 30 A power strip).
4.
Turn on the power strip.
5.
Press the "I" side of the enclosure's power switch.
The Power Indicator on the front of the enclosure illuminates.
6.
Apply power to the source and destination devices.
The system is ready to attach a serial controller. A PC is required to run the APGraphic EQ software for
system setup; see page 17.
