SUBWOOFER MODE ( GX-4000 / GX-5000 / GX-7000 only ) :
This mode sends low frequencies to your speakers without the use of an external cross-
over. The subwoofer operation can be operated in stereo, parallel, or bridge mono modes. Change the different operating modes by flipping the mode switch on the rear
of the unit to your desired operating mode. Also, set the subwoofer mode switch to the “SUBWOOF” position. Use the frequency selector to adjust the subwoofer output
frequency from 20Hz to 200Hz. The different subwoofer modes are listed as follows:
BRIDGE SUBWOOFER -
This operation allows you to get the most possible power out of your amplifier for the sole purpose of running a high powered subwoofer
loudspeaker in mono. To avoid amplifier overheating, never run the amplifier below 4 ohms in this mode. In this mode you may use the frequency adjustment on the rear
of the amplifier, to control the frequency output level. Frequencies may be adjusted from 20Hz to 200Hz. Page 1 /
19 details a typical Bridge Subwoofer set-up.

STEREO SUBWOOFER -
This operation is similar to the Bridge Subwoofer operation but in stereo. This operation allows you to run several subwoofers down to a
minimum of 2 ohms. To avoid amplifier overheating, never run the amplifier below 2 ohms in this mode. Set up this mode as you would a standard Stereo set-up. Be sure
both channels are set to “SUBWOOF.” In this mode you may use the frequency adjustment on the rear of the amplifier, to control the bass frequency output level.
Frequencies may be adjusted from 20Hz to 200Hz. Page 1 /
20 details a typical Stereo Subwoofer set up.

PARALLEL SUBWOOFER -
This operation is similar to the Stereo Subwoofer operation but in Parallel. When running subwoofers, it is usually recommended to run
them in mono mode to achieve a cleaner tighter low end. This operation allows you to run several subwoofers down to a minimum of 2 ohms. To avoid amplifier
overheating, never run the amplifier below 2 ohms in this mode. Set up this mode as you would a standard Stereo set-up. Be sure both channels are set to “SUBWOOF”
and the mode switch is set to “Parallel.” In this mode you may use the frequency adjustment on the rear of the amplifier, to control the bass frequency output level.
Frequencies may be adjusted from 20Hz to 200Hz.
ONE CHANNEL NORMAL / ONE CHANNEL SUBWOOFER (BI-AMP) -
You may also use your amplifier to bi-amp your system. You may use one side of the amplifier
to power a subwoofer and the other side to power a full range speaker. Follow the set up guides listed above to mix and match your operations.
