ANALOG INPUTS SECTION
B. Balanced Analog XLR Inputs
A 3-pin female XLR connector for each channel.
A 3-pin female XLR connector for each channel.
C. Balanced Analog XLR Loop-Through
Outputs
Two 3-pin male XLR output connectors are pro-
vided (one per channel). The signal at these
connectors is paralled with the input signal for
feeding the input signal to other amplifiers.

These two connectors accept 2-pole or 4-pole
Speakon connectors. See Figures 2.5 through
2.10 and Tables 1, 2 and 3 for connector wiring.
The top Speakon connector is wired for both
channels so it can be used for bridge-mono
wiring or for stereo wiring of two speakers to a
single Speakon connector.

E. Binding Post Output Jacks
One pair per channel of high-current, 60A
color-coded binding posts. Accepts banana
plugs, wire or spade lugs.

G. Reset Switch/Circuit Breaker
If the current draw of the amplifier exceeds safe
limits, this breaker automatically disconnects
the power supply from the AC mains. The
switch resets the circuit breaker.

H. AES/EBU Digital Input
This 3-pin female XLR connector accepts a dig-
ital signal in the AES/EBU format.

I. AES/EBU Digital Loop-through Output
Male XLR active/re-clocked AES/EBU digital
loop-through. The signal at this connector
duplicates the digital input signal for feeding
the input signal to other amplifiers.

It is not recommended to loop through more
than four amplifiers. If larger distribution of AES
is needed, the use of an AES distribution ampli-
fier is recommended.

L. Network Connector
This Ethernet connector accepts an RJ-45 con-
nector for networking. Built into the connector
is a yellow LINK ACT indicator that shows net-
work activity, and a green 100Mb indicator that
shows a 100Mb network connection.
