Component Requirements & Connections
22
• Must include components that are connected in a certain
order to prevent communication from terminating. Power
amplifiers such as the Nº432/431 must be the last components
in a slave chain.
Note The slave chains in this section include preamplifiers and power
amplifiers. However, slave chains can also include digital audio
processors and digital transports. Refer to the appropriate
documentation for information about including these Mark
Levinson components in a slave chain.
The table below indicates slave chain requirements for preamplifiers
and power amplifiers.
Preamplifier
(e.g., Nº320S)
Power Amplifier
(e.g., Nº432/431)
• No maximum number per slave chain.
• Connect the or slave out communication port on
the preamplifier to the input communication port
on the first power amplifier.
• Maximum of six per slave chain.
• Connect the input communication port on the first
power amplifier to the or slave out communication
port on the preamplifier.
• Connect up to six power amplifiers in a “daisy chain”
using input-to- control communication port
connections. The control communication port on
the last power amplifier is not connected.
To create a slave chain that includes the Nº432/431:
1. Make sure the Nº432/431 and all associated components are
powered off.
2. Connect the input communication port on the first
power amplifier to the or slave out communication port
on the preamplifier.
If desired, connect the control communication port on
the first power amplifier to the input communication
port on another power amplifier. Up to six power amplifiers
can be included in a slave chain using “daisy chain”
input-to- control communication port connections. The
control communication port on the last power amplifier
is not connected.
