400M Neo 

Series

 

 

Rear Panel Layout 

 

 

Figure 1: Nēo 400M Rear panel 

 
 

The rear panel will look similar to Figure 1 (above). There is one balanced (differential) input on an XLR connector 
and one unbalanced (single-ended)  input on a RCA connector.  There is no switch to toggle from balanced mode 
to single-ended mode. You may operate the amplifier in either mode, but only one mode at one time  

 

When you’re using the balanced XLR inputs, 

you must 

first remove the factory installed “dummy” XLR 
jumpers

 (see figure 2 below) from the back panel XLR 

connectors and store them in a safe place.  This jumper 
is required ONLY when using the single-ended RCA 
input. When you decide to switch to single-ended input 
mode, you must reinstall the XLR jumper (between pins 
1 and 3)  exactly as shown below: 

 

The left side of the rear panel has a pair of 12 Volt 
triggers, each on a 1/8” mini-jack; one input and one 
output, the latter for use if you need to “daisy chain” a 
second power amplifier on the same trigger circuit. 
Immediately to the right of these 12V triggers is an RS-
232 input on a DB9 connector. 

 

In the middle of the rear panel you will find a pair of 
heavy duty gold-plated speaker binding posts. 

 

On the far right side, you will find (from top to bottom); 
The power “main switch”; The “AC Fuse” socket cover 
and the “AC in” IEC receptacle for the power cord.
