Banana plugs can also be used to connect the speaker cables to the
loudspeaker binding posts. Banana plugs are not available on the
230 VAC model.
DO NOT OVERTIGHTEN the binding posts. The innovative
design of these binding posts provides more leverage; hence,
high-contact, tight pressure connections are achieved when
finger-tightened.
DO NOT FORCE the binding post "wings" over a bent or
oversized connector. Doing so may damage the binding post.
The rear panel of the amplifier has two trigger connectors – one
input and one output. The trigger input can receive a 3-12V
DC signal from a connected component. The trigger output
passes through the trigger input signal, 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 mode, by the state of other devices
in the system. The trigger output can also affect other power
amplifiers in the same manner.
Receiving a trigger signal causes the amplifier to change its power
state. If the amplifier is powered on, then 0V on the trigger signal
puts the amplifier into Standby or mode. Conversely, an amplifier
in Standby mode is powered on when 3-12VDC is received on the
trigger input.
The Ethernet port is a standard 10Base-T connection for use with
external control and networking. The Nº500H series supports
connection to a router or network, and to a PC-compatible
computer.
This connection is designed for use with proprietary Mark Levinson
external controllers, such as ML Net, or can provide serial port
control. For a list of the serial commands available, refer to the
separate document, No. 5 series Power Amplifier Serial Protocol
Definitions.
Provides AC power to the amplifier when the supplied power cord
is connected from the AC Input connector on the rear panel to an
electrical outlet.
Before operating the amplifier, verify that the voltage label
near the AC input connector indicates an operating voltage
compatible with the voltage level of the electrical outlet you
intend to use.
