Driver Mute; System Lvl; Maintenance - Genelec DSP 8260A Operating Manual

AES/EBU CH
This selects the audio channel(s) available on the AES/EBU cable
to be reproduced by the loudspeaker. Turning both switches on
reproduces the sum of the two channels on the AES/EBU cable.
Turning both switches off has the same effect which has been
done deliberately to avoid the situation where no input channel
is selected and the loudspeaker is effectively muted. When two
channels are selected, 6 dB of attenuation is automatically ap-
plied to avoid overloading the loudspeaker.
If the AES/EBU cable is operated in dual-wire mode (typically
192 kHz sampling frequency) one AES/EBU cable carries only
one audio channel. The loudspeaker detects this situation auto-
matically and the channel selection switches have no effect.

Driver Mute

These two switches allow you to mute the treble driver (marking
TW) and bass driver (marking "WF") independently. This may be
useful to diagnose if a transducer is faulty.
On the 8260A the marking "TW" is replaced with "COAX" and this
switch mutes both the treble and midrange parts of the coaxial
driver unit.

System Lvl

These switches allow scaling down of the loudspeaker output.
The signal sent to the "Thru" output connector is not affected.
The switches are additive, for example, "–30 dB" attenuation is
achieved by turning on the "–10 dB" and "–20 dB" switches. The
effect of these switches is combined with the effect of the rotary
level adjustment control. This results in total possible attenuation
of 42 dB, 30 dB by the system level switches and another 12 dB
by the rotary control.
Using 7000 Series Analog Subwoofers
with 8200 Series DSP Loudspeakers
Please follow the steps below to integrate an analog subwoofer
into a system of DSP loudspeakers:
• Connect cables carrying analog audio to the 7000 Series
analogue subwoofer first.
• Connect the subwoofer outputs to the analog inputs of the
8200 Series DSP loudspeakers.
• Connect the GLM Control Network to the loudspeakers.
• Make a System Setup in GLM. It will consist of only
loudspeakers as this is all the network can see, so suitable
Rapid Cabling Presets are "Stereo Pair (Analog)" and "5.0
Surround System (Analog)".
• Run AutoCal and review and the results to check for large
dips at or above 85 Hz. Move the loudspeakers and repeat
AutoCal if there is a problem.
• Press "Finish", then in the Main Page select "Menu | Store
Acoustic Settings to All Online Loudspeakers" and close
GLM.
• For each DSP loudspeaker, turn it off, select "Stored" on the
back of each loudspeaker to enable the internal Acoustic
Settings, and then turn it on again.
• To set the phase control on the subwoofer, connect the
Center channel output of the subwoofer to the loudspeaker
to be used to align phase.
• Follow the instructions in the subwoofer user manual for
setting phase and level.

Maintenance

No user serviceable parts are to be found within the loudspeaker
enclosure. Any maintenance or repair of the loudspeaker should
only be undertaken by qualified service personnel.
