Using the GSR18 Sub
To add a GSR18 to your system:
Using XLR or TRS cables, connect the output of your mixer or other device to the Inputs on the back of the GSR18. If you’re
only using a mono feed from a mixer or similar source, connect it to the Left Input on the GSR18.
You can also use a GSR18 subwoofer in combination with a pair of GSR12 or GSR10 speakers to form a powerful, full-range sys-
tem, as shown in the figure below.
To connect a GSR18 and a pair of GSR speakers for stereo operation:
1
On the back of each speaker, turn the Level control down (counter-clockwise to Min). Make sure power is Off.
2
Connect two XLR or 1/4-inch TRS cables from the Left and Right outputs of the mixer or other device to the Left and Right Ste-
reo Inputs on the back of the GSR18.
3
Using XLR cables, connect the L/R Stereo Outputs on the back of the GSR18 to the Input input on the back of each GSR10 or
GSR12 (left to left, right to right).
4
On the GSR10 or GSR12 speakers, do the following:
• Make sure the Level knob is down (set to Min).
• Make sure the Mic/Line button is set to Line.
• Rotate the Mode knob to select a preset as appropriate (if you’re not sure, leave it at Normal). For more information, see
“Modes for Speaker Presets” on page 11.
• Make sure the HPF 75Hz button is “in” (HPF engaged) to keep bass from GSR10/GSR12 from overlapping with the GSR18.
5
Use the Power switch on the back of the GSR18 to power it on.
6
To check levels, begin playback of audio through the mixer with its Mains or master output set to its recommended position,
then slowly raise the Level knob on the back of the GSR18.
7
Raise the levels on the other speakers by setting their Level knobs to the desired position.
Using the Phase Switch on the GSR18
If the GSR18 Level knob is up high but you’re still not satisfied with the amount of low-end you’re hearing, try engaging the
Phase switch on the back of the GSR18. Inverting the signal in this way can help minimize frequency conflicts caused by room
acoustics, distance, or speaker placement.
