SUBWOOFER MODE : 

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 “SUB” 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 amp, to control the 

frequency output level. Frequencies may be adjusted from 20Hz to 200Hz. Page 9 / Figure 14 details a typical Bridge 

Subwoofer set up.

Operating Modes

PARALLEL MONO:

 

Parallel ties the two channel line inputs together so that they will both be driven by the same 

signal, without the need for external jumpers or wiring. Both amplifier channels will operate independently. Though they 

carry the same signal, their gain controls affect only their respective channels, and they both must use their respected 

speaker outputs. Never attempt to parallel the speaker outputs, this may cause serious damage to your amplifier! This 

mode is recommended when using the V PLUS amplifier to run bass speakers, to achieve better low end. To run in 

parallel mono mode connect your system as you would if you were going to run in stereo mode. Then flip the mode 

switch to Parallel. Be sure the amp is off or the power is disconnected before making any changes.
