Testing Mode - Genelec SAM 1235A Manual

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.

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.

CAUTION! The "Woofer" and "Midrange/

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 1235A 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
