Functions on Switch Group, Stored / Manual Ctrl

Functions on Switch Group 2

Stored / Manual Ctrl

This allows the selection between two basic methods of controlling the loudspeaker in the stand-alone mode. “MANUAL CTRL” refers to controlling the loudspeaker using the controls on the loudspeaker’s back panel. The “STORED” refers to using settings stored inside the memory of the loudspeaker. These settings are made using the GLM and the GLM Control Network. There is additional functionality compared to that offered by the room response correction switches on the back panel. Note that setting the selector to “STORED” overrides all back panel switches except “DRIVER MUTE”. These switches only have effect when the selector is set to “MANUAL CTRL”.

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 applied 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 automatically 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.

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 main loudspeakers.
