“DIGITAL IN AES/EBU” Connector
Use this female XLR connector for AES/EBU formatted digital
audio input signals. This input is selected automatically when
a valid digital audio signal is present, and overrides the analog
input.
Depending on the digital hardware, transmission of a 192 kHz
sample rate is achieved using a double speed, single chan-
nel/cable interface. This is called dual-wire mode. In this case
one cable per channel is used and no channel selection is
required. Dual-wire mode is automatically detected by the in-
put stage.
If the digital source device has a volume fader that controls
the digital level, it may be advantageous to lower the level
control either on the computer interface or on the monitor’s
back panel controls, which in turn will force the use of more of
the digital [bit] resolution in the volume control.
If the digital inputs are used, all audio outputs are referenced
to 0 dBFS (digital Full Scale, the largest level that may be rep-
resented in the AES/EBU signal). These monitors produce 100
dB SPL at 1 meter in free space for a digital input signal of
–30 dB FS.
“DIGITAL THRU AES/EBU” Connector
This male XLR carries an unaltered copy of the digital signal
fed into the “DIGITAL IN AES/EBU” connector. It can be used
for daisy-chaining up to four monitors together.
“ANALOG IN” Connector
Use this connector for analog audio signals. The maximum
input level is +7.0 dBu RMS on models 8240A and 8250A and
+22.0 dBu RMS on models 8351A and 8260A. When A/D con-
verter input clip occurs the front panel light turns momentarily
red, indicating the overload condition.
“CONTROL NETWORK” Connectors
Use these RJ-45 sockets to connect the monitor to the propri-
etary Genelec Loudspeaker Manager™ (GLM™) network only.
This connector is not Ethernet LAN compatible. Do not con-
nect to Ethernet LAN.
“12 V REMOTE” Connector (8260A only)
You can set up remote controlled powering up and down of
the 8260A with 12 V voltage connected to this connector. The
minimum current needed to actuate this function is 70 mA.
