POWER AND INITIALIZATION

Power Mains Connections

Use the supplied power cable to connect the DFR22 Audio Proces- sor to an active 100–240 Vac power source, as shown in Figure 6. The Power LED on the front panel will glow green when power is applied.

NOTE: The DFR22 Audio Processor is designed to operate contin- uously. Therefore, there is no power on/off switch.

Initialization

Once power is applied, the DFR22 Audio Processor takes approxi- mately 5 seconds to initialize. When initialization is complete, the Input/Output LEDs will flash, as shown in Figure 7. The DFR22 is ready to use once the LEDs stop flashing.
