H. Preset Indicator 

LED flashes 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. 

I. Reset Button

 

To restore factory default settings: Press the Reset Button with a 

thin, non-conductive object, then turn on amplifier power, and 

continue to hold the reset button  until the Preset light comes 

on green (approximately 16 seconds)..

J. Data Indicator 

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

DIGITAL INPUTS SECTION
K. AES/EBU Digital Input 

This 3-pin female XLR connector accepts a dig ital signal in the 

AES/EBU format.

A. Fans 

Provide front-to-back forced airflow for cooling.

ANALOG INPUTS SECTION
B. Balanced Analog XLR Inputs 

A 3-pin female XLR connector for each channel. 

OUTPUTS SECTION
C. Speakon

®

 Output Connectors 

Two high-current, 50A Neutrik

®

 Speakon

®

 NL4MLP 

(mates with NL4FC and NL4), for channels 1+2 or 

3+4 and one NLT8 for channels 1 thru 4. Class 2 

output wiring required.
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 

2 speakon connectors are wired each for stereo 

operation off of one connector, the bottom NL8 

speakon connection is for four way operation off 

of one connector.

D. Binding Post Output Jacks 

One pair per channel of high-current, 60A 

color-coded binding posts. Accepts banana 

plugs, wire or spade lugs. 

E. Power Cord Connector 

32 amp PowerCon

®

 AC Inlet. Voltage range is 

indicated above IEC inlet.

F. Reset Switch/Circuit Breake

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.

G. MAC Address

 

This specific amplifier’s network identifier that is 
burned into its firmware.

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.

NETWORKING SECTION
L. Link/Act Indicator 

Shows net work activity.The LINK ACT LED illuminates when 

the network port is connected and flashes when network 

activity is detected. 

M. Network Connector 

This EtherCon

®

 Ethernet connector is for networking. 

Warning:

 Only connect to networks that remain inside the 

building.

N. Cond Indicator

 

Turns on if the amplifier 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.

7.1 Introduction

The LCD Display Screen and its controls let you configure the 
ampli fier and access many features that before were available only 
through a remote computer. Also, you can recall DSP presets via 
the front panel. (Some DSP parameters cannot be adjusted with 
the LCD Display Screen. That is done in System Architect.) 

Figure 7.1 shows the parts of the LCD Display Screen. Its 
functions are described below. NOTE: Listed functions can also be 
controlled in System Architect. 

Here’s how to access the various menus and settings in the LCD 

Display Screen:

7 Advanced Operation

Figure 7.1 Parts of the LCD Control Screen

 
• Starting from the Attenuation screen, press 

Menu/Exit

 to go to 

the Menu screen.
• Press 

Next 

to go to the next item in the menu. 

• Press 

Prev

 

to go to the previous item in the menu. 

• Turn or press the 

Encoder 

knob to change the value of a 

dis played  parameter.
• When you see a menu screen, push the knob once to see the 
items in that menu. Or press 

Next 

to go to the next menu.

• Press 

Menu/Exit 

to leave the menu and return to the previous 

screen at any time.
Some menu items require confirmation: after you request a change, 
the display might say “Press and hold.” To confirm a change, press 
and hold the 

Encoder

 knob. If you don’t want the change to occur 

during a confirmation, turn the knob or wait five seconds. 
The entire front panel or any selected screens can be locked out or 
set to read only status using System Architect software. Locked-out 
screens will either say “Lockout” or the individual parameter will 
say “N/A”. If a change is attempted the screen will say “Changes 
Disabled”.
