supply is stable.
The ANALOG IN connector is used for analog audio signals. The
maximum input level is +25 dBu. These monitors produce 100
dB SPL sound level at 1 meter in free space for an analogue
input signal of -6 dBu.
The DIGITAL IN AES/EBU female XLR connector is for AES/
EBU formatted digital audio input signals. This input is selected
automatically when a valid digital audio signal is present.
Analog input is selected when the AES/EBU signal input is
disconnected. The AES/EBU input supports two channels in a
single cable). When the digital source device controls the digital
output level, it may be advantageous to lower the level on the
monitor's controls, which will enable the use of a higher digital
signal level with more digital resolution. With digital inputs the
audio is referenced to 0 dBFS (dB relative to the digital full scale,
the largest level that can be represented in the AES/EBU signal).
These monitors produce 100 dB SPL sound level at 1 meter in
free space for a digital input signal of –30 dBFS. The DIGITAL
OUT male XLR carries an unaltered copy of the digital signal fed
into the digital in connector. This enables daisy-chaining up to
four monitors.
The CONTROL NETWORK RJ-45 connectors are used with
Genelec Loudspeaker Manager™ (GLM™) network. These
connectors are not Ethernet LAN compatible. Do not connect
to Ethernet LAN.

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.
