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 main loudspeakers.
•
Connect the GLM Control Network to the main loudspeakers.
•
Make a System Setup in GLM. It will consist of main 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 85Hz. 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.
Safety considerations
Although the 8240A and 8250A have been designed in accordance with international safety standards,
to ensure safe operation and to maintain the loudspeaker under safe operating conditions, the following
warnings and precautions must be observed:
.
Servicing and adjustment must only be performed by qualified service personnel.
The loudspeaker enclosure must not be opened.
2.
Do not use this product with an unearthed mains cable or a mains connection without the

4.
Note that the amplifier is not completely disconnected from the AC mains service unless
the mains power cord is removed from the amplifier or the mains outlet.
5.
Free flow of air behind the loudspeaker is necessary to maintain sufficient cooling.
Do not obstruct airflow around the loudspeakers.
