Nº53 Power Amplifier

Control

The control section of the Nº53 rear panel contains the Ethernet and Link2 ports, the Power Save Mode switch, and the trigger input and output.

Trigger Input and Output

The rear panel of the Nº53 has two trigger connectors – one input and one output. The trigger input can receive a 3-12Vdc signal from a connected component. The trigger output connects directly to the trigger input connector, enabling a daisy-chain of amplifiers to be controlled by a single trigger signal.

The triggers enable the power amplifier to be automatically powered on, or put into Standby or Power Save mode, by the state of other devices in the system.

Receiving a trigger signal causes the Nº53 to change its power state. If the trigger input receives a 3-12Vdc signal, the amplifier powers up to the “On” mode. If the trigger input transitions from 3-12Vdc to 0Vdc, then the Nº53 returns to the Standby or Power Save mode.

Power Save Mode Switch
The Power Save Mode switch on the rear panel provides the	11
energy-saving mode.

•When set to ON, the amplifier enters Power Save mode when the rear panel Power switch is turned on. The front panel Standby button switches the amplifier between Power Save and On modes.

•When set to OFF, the amplifier enters Standby mode when the rear panel Power switch is turned on. The front panel Standby button switches the amplifier between Standby and On modes.

When Power Save mode is active, AC power is only connected to the low-voltage power supply, communication circuits, and control circuits. Therefore, nonaudio functions such as ML Net and Link2 are active, but the audio circuits are NOT powered. This means that there may be a small delay before the amplifier is fully operational when taken out of Power Save mode.

Link2 Ports

Use the Mark Levinson Link2 protocol to link together two or more Mark Levinson components. For more information on the Link2 protocol and how to use it with the Nº53, refer to the “Link2” section found later in this manual.
