“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 analogue input.
Depending on the digital hardware, transmission of a 192 kHz sample rate is achieved using a double
speed, single channel/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 input stage.
If the digital source device has a digital level monitor pot or graphical volume fader that controls the
digital level, it may be advantageous to lower the level control either on the computer interface or the
loudspeaker’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 represented in the AES/EBU signal). Genelec DSP loudspeakers produce 100 dB SPL
at 1 meter in free space for a digital input signal of –30 dB FS. It is advantageous to keep the digital level
as high as possible.
“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 loudspeakers together.
“ANALOG IN” connector
Use this connector for analog audio signals. When operating an 8200 Digital system in the analog mode
the A/D converter must not be overloaded, otherwise distortion will be heard. The maximum analog input
level is +18.5 dBu peak.
If the “Level” control on the 8200 back panel is reduced (turned counter-clockwise), the acoustic output will
be reduced. This control decreases the output from the D/A converters. Ideally the Level control should
be set to force the use of more of the input range of the A/D converter without overloading it. Remember,
there is no headroom above the maximum input to the A/D conversion. Once the analog signal reaches
+18.5 dBu, it attains the value “digital 1” or 0 dBFS.
“CONTROL NETWORK” connectors
Use these RJ-45 sockets to connect the loudspeaker to the proprietary Genelec Loudspeaker Manager™
(GLM™) network only. This connector is not Ethernet LAN compatible. Do not connect to Ethernet LAN.
Front panel warning light
Normally the light on the front panel of an 8200 loudspeaker is green, indicating that the loudspeaker is
in normal operational mode.
