3.5Back Panel Controls, Indicators 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 provided (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.

These two connectors accept 2-pole or 4-pole Speakon® connectors. See Figures 2.5 through

2.10and 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. LED is green if the preset values have not been changed once loaded. LED is yellow if the preset values have been changed since they were loaded.

J. Reset Button

To restore factory default settings: Press the Reset Button with a thin, non-conductive object, then turn on amplifi er power, and continue to hold the reset button until the Preset light comes on green (approximately 16 seconds)..

K. Data Indicator

Flashes yellow only when the amplifi er is polled for data, or is polled to see whether it is online.

DIGITAL INPUTS SECTION

L. AES/EBU Digital Input

This 3-pin female XLR connector accepts a digital 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 amplifi er is recommended.

NETWORKING SECTION

N. Link/Act Indicator

Shows network 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. Warning: Only connect to networks that remain inside the building.

P. Cond Indicator

Turns on if the amplifi er is set to be the CobraNet conductor. The CobraNet conductor is a CobraNet node that provides the master timing clock for the CobraNet digital audio transport network.
