Front Panel

The front panel contains one LED and one button, as shown.

Status LED

Indicates the operating state of the Nº53 and provides basic

diagnostic information when a fault condition occurs. Refer to the

table below for descriptions of LED behavior.

Refer to the “Troubleshooting” section in the back of the manual

for a description of the Status LED behavior when a fault is detected.

Standby Button

Places the Nº53 into Standby or Power Save mode, depending upon

the state of the rear panel Power Save Mode switch. Pressing the

Standby button while the amplifier is in Standby or Power Save

mode turns on the amplifier.

Standby mode provides full AC power to the amplifier but mutes

the outputs. Power Save mode powers only the low-voltage power

supply, control circuits, and communication circuits so that only

nonaudio functionality is available.

Note When the amplifier enters or exits Power Save mode, there’s an

extended initialization period before the amplifier is fully powered on.

During this period, additional Standby button presses are ignored.

LED Behavior Description

Fully lit Indicates that the amplifier is powered on.

Slowly blinking Indicates that the amplifier is in Standby mode.

Dimly lit Indicates that the amplifier is in Power Save mode

or, when the Power switch is turned on, that the

amplifier is initializing.

Not lit Indicates that the amplifier is powered off.
