Genelec Loudspeaker Manager™ (GLM™) network. These
connectors are not Ethernet LAN compatible. Do not connect

Stand-Alone Control Functions
Bass Roll-Off Control
Bass Roll-Off control attenuates the monitor’s output near the
cut-off frequency. Attenuation levels of -2 dB, -4 dB or -6 dB
(both switches ON) can be selected.
Desktop 160 Hz
The desktop low frequency control (switch 5) attenuates the
bass frequencies around 160 Hz by 4 dB. This feature is de-
signed to compensate for the boost often occurring at this fre-
quency range when the monitor is placed upon a meter bridge,
table or similar reflective surface.
Bass Tilt Control
The Bass Tilt control switches (swiches 3 and 4) offer three at-
tenuation levels for the bass response below 800 Hz, usually
necessary when the monitors are placed near room boundaries.
The attenuation levels are -2 dB, -4 dB and -6 dB (both switches
ON).
Treble Tilt Control
Treble Tilt control allows adjusting the treble response above 5
kHz by +2 dB, -2 dB or -4 dB, which can be used for correcting
an excessively bright or dull sounding system or to compensate
for high frequency level loss if the monitor is placed behind a
screen. The -2 dB setting is selected by turning both switches
to “ON.”
LED Disable
This switch shuts off the front panel LED light.
ISS
This switch activates or deactivates the ISS automatic power
saving function. The default time for ISS activation is 60
minutes, but can be adjusted in GLM.
Digital
The Digital switch selects the digital audio channels on the
AES/EBU. Turning both switches on reproduces the sum of the
A and B channels. A 6 dB of attenuation is applied to avoid
overloading the monitor. If the AES/EBU cable is operated in
dual-wire mode, the monitor detects this automatically and the
channel selection switches have no effect.
Level
The Level switches scale down the monitor output level in 10 dB
steps. The effects of these switches add up and combine with
the effect of the rotary level adjustment control. The combined
total setting range is -42 dB.
Stored
Stored switch selects the use of the controls on the monitor’s
back panel or the settings stored inside the monitor memory using
Figure 4. The location of the acoustic axis.
Figure 5. Symmetrical layout and keeping the acoustic
axis clear from obstructions minimizes reflection surfaces
and maintains accurate localisation because reflections are
symmetrical.
