Figure 7. Selecting ISS setting.

Single-wire mode of AES/EBU is the 

default and the older dual-wire mode is 
automatically detected if used at the source. 

The standard AES/EBU cable carries 

two channels of audio, called A and B. As 
a default, both A and B subchannels are 
reproduced by the monitor. GLM software 
is used to set up the monitor to specific 
channel assignments. 

RAM-XL Amplifier  

Power Button

The power button in the middle of the 
RAM-XL amplifier front panel controls 
several functions. 

A short press of the power button turns 

the RAM-XL on or off. Turning on, the power 
button light flashes rapidly, and lights 
on steadily when the turn-on has been 
completed.  Testing modes are explained 
later in this manual.

Setting ISS™ 

The Intelligent Signal Sensing™ (ISS™) 
puts the monitor to a power-saving 
stand-by mode automatically. The factory 
setting for ISS is "OFF." The ISS can be 
activated using the GLM software (see 
Figure 5). When ISS is active, if no audio 
signal is sensed during the selected time, 
the monitor powers down. The monitor will 
power up again once a signal is detected. 
The ISS setting is applied to all ISS-enabled 
monitors in the currently selected Setup. 

Connectors on the RAM-XL

 

“MAINS INPUT” Connector

Connect to the mains supply of 100 - 120 
VAC or 220 - 240 VAC 50/60 Hz.

 “DIGITAL IN AES/EBU” Connector

The monitor defaults to reproducing an 
analog input signal. The digital audio 
AES/EBU input is selected automatically 

when a valid digital audio signal is 
presented. Use GLM software to define 
the AES/EBU subframe to monitor. 

 “DIGITAL THRU AES/EBU” Connector

This output carries an unaltered copy of 
the digital audio signal and can be used 
for daisy-chaining the signal to up to three 
additional SAM monitors or subwoofers.  

“ANALOG IN” Connector

The maximum input level of the analog 
input is +25.0 dBu. The analog input must 
not be overloaded, otherwise distortion 
will result. When the maximum input is 
exceeded, the enclosure front panel light 
turns red, indicating the overload. 

The sensitivity of the monitor 

system is set using the GLM software. 
Coming from the factory, the analog 
input is set to the highest sensitivity, 
resulting in a sound output of 100 dB 
SPL for a -6 dBu analog input signal.  

“CONTROL NETWORK” Connectors

The RJ45 sockets connect the monitor 
to the proprietary Genelec Loudspeaker 
Manager™ (GLM™) network. Do not 
connect to Ethernet LAN. 

“Loudspeaker Connectors” Group

“LED” Connector
This RJ45 socket is a connection for the 
front panel warning LED.

“Woofer” Connector
A standard four-pole Speakon cable 
connects to the woofers.

CAUTION! 

The ”Woofer” and ”Midrange/

amplifier can output hazardously high 
voltages. To ensure safety, the wiring 
connected to these connectors must be 
installed by a qualified and trained person.

Front Panel Light Functions

The green light on the DCW panel of 
a 1234AC enclosure indicates normal 
operation. A yellow light indicates certain 
activities when the GLM control software 
is used. The light turns red in an overload 
condition. The overload light (red) is 
activated by several events:

•  Exceeding the maximum input of the 

analog input

•  Reaching close to the digital input 

maximum (high likelihood of digital 
clipping)

•  Overload of drivers or amplifier, or 

clipping in the power amplifier 

•  An error detected in the AES/EBU 

audio data

If a red warning light appears on the 
monitor, turn the source level down. Ensure 
that there are no bit errors in the AES/EBU 
digital audio data transmission.

Testing Mode

Once on, when the power button is pressed 
for a long time, the RAM-XL enters a mode 
for system testing. This special mode
