CONNECTING THE A 51 AC POWER CORD

AC Power Connections

We recommend that you plug your A 51 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 51 requires AC power that is continuous rather than switched on and off.

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

The A 51 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 51’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 Youll 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 51.

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