Nº500H Series Power Ampliﬁer

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amplierispoweredon,then0Vonthetriggersignal

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.
