The subwoofer operation can be operated instereo, parallel, or bridge modes. Change the different operating modes by flipping the mode switch on the rear of the unit to your desired operating mode. Also, set thesubwoofer mode switch to the ”SUBWOOF” position. Use the frequency selector to adjust the subwoofer output frequency from 20Hz to 200Hz. The different subwoofermodes 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 subwooferloudspeaker 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 rearof the amplifier, to control the frequency output level. Frequencies may be adjusted from 20Hz to 200Hz. Page 11 / 20 details a typical Bridge Subwoofer set-up.FigureSTEREO SUBWOOFER - This operation is similar to the Bridge Subwoofer operation but in stereo. This operation allows you to run several subwoofers down to aminimum 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 sureboth 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 12 / 21 details a typical Stereo Subwoofer set-up.FigurePARALLEL SUBWOOFER - This operation is similar to the Stereo Subwoofer operation but in parallel. When running subwoofers, it is usually recommended to runthem 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 amplifieroverheating, 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 amplifierto 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.page 11Bridge Subwoofer Mode Speaker Set-UpFigure 20 Use the two red terminal from the Binding Post topower a subwoofer speaker in mono-bridge mode.Introduction Front Panel Rear Panel Set Up Speakon Assembly Protection Features SpecificationsOperating ModesUNiKA NA-13600/NA-17600/NA-21600
