CONNECTING THE AC POWER CORD

 

 

AC Power Connections

We recommend that you plug your A 23 into the same AC wall outlet or power strip that powers your other audio components, especially the preamplifier or system controller. Having all the audio components on the same power circuit helps prevent hum caused by possible ground loops. The A 23 requires AC power that is continuous, rather than switched on and off.

What You’ll Need:

An IEC 65 AC Cord (provided)

An AC outlet or high quality AC power strip within reach of the AC cord

Before Connecting

Remove power to all the components in your audio system.

To Connect

1Plug the female end of the AC cord to the AC receptacle on the rear of the A 23.

2Plug the male end of the AC cord to an AC outlet or power strip.

AC Voltage Selection Switch

The A 23 can operate on either 110-120 Vac or 220-240 Vac operation. When you purchased your A 23, its rear panel Voltage Selector switch was already set for the proper voltage in your area. Nevertheless, it’s wise to double-check it before plugging into an AC outlet.

If you move to a location with a different line voltage, you can easily convert the A 23.

For 110-120 Vac Operation: Remove the lock-out bracket with a phillips screwdriver. Next, slide the switch sideways toward the left until the indent on the switch lines up with the 115/60Hz label on the rear panel. The main fuse value should be 6.3 A for 110-120 Vac operation

For 220-240 Vac Operation: Remove the lock-out bracket with a phillips screwdriver. Next, slide the switch sideways toward the left until the indent on the switch lines up with the 230V/50Hz label on the rear panel. The main fuse value should be 3.15 A for 220-240 Vac operation

If you’re unsure about the correct setting for your region, please consult your Parasound dealer or a qualified service technician.
