3 Operation
3.5 Back Panel Controls, Indica tors
and Connectors
A. Fans
Provide front-to-back forced airfl ow for cooling.
ANALOG INPUTS SECTION
B. Balanced Analog XLR Inputs
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
paralleled with the input signal for feeding the input
signal to other amplifi ers.
OUTPUTS SECTION
®
D. 4-Pole Speakon
Output Connectors
®
Two high-current, 50A Neutrik
®
Speakon
NL4MLP
(mates with NL4FC and NL4), one per channel.
Class 2 output wiring required.
Operation Manual
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.
F. Power Cord Connector
Standard 20 amp IEC inlet. Voltage range is
indicated above IEC inlet.
G. Reset Switch/Circuit Breaker
If the current draw of the amplifi er exceeds safe
limits, this breaker automatically disconnects
the power supply from the AC mains. The switch
resets the circuit breaker.

H. MAC Address
This specifi c amplifi er's network identifi er that is burned into its
fi rmware.
I. Preset Indicator
LED fl ashes to signal the number of the current preset if active.

This 3-pin female XLR connector accepts a dig ital signal in the
AES/EBU format.
M 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 amplifi ers.
It is not recommended to loop through more than four
amplifi ers. If larger distribution of AES is needed, the use of
an AES distribution ampli fi er is recommended.
NETWORKING SECTION
N. Link/Act Indicator
Shows net work activity.The LINK ACT LED illuminates when
the network port is connected and fl ashes when network
activity is detected.
O. Network Connector
®
This EtherCon
Ethernet connector is for networking.
