10CONNECTING THE A 52 AC POWER CORD

AC Power Connections

We recommend that you plug your A 52 into the same AC wall outlet or power strip that pow- ers 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 52 requires AC power that is continuous rather than switched on and off.

110 V - 120 V or 220 V - 240 V Operation

The A 52 can operate on either 110 V - 120 V or 220 V - 240 V. The correct line (or “AC mains”) voltage for your unit is marked on its carton. Changing the A 52’s operating voltage involves rewiring internal connections for both its main power transformer and standby power trans- former, plus changing fuse values. Since there is a risk of electric shock, voltage changes must be referred to a qualified technician.

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 52.

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