You must decrease the gain controls to their lowest levels to protect the speakers from any popping noise. Stereo Operation - Page 14/Diagram 15 details an example of a typical stereo set-up. Be sure that your front gain controls are turned down to their lowest level (full counter-clockwise). Be sure not to raise the volume to the clip level, however an intermittent clip signal is acceptable. Mono Bridge Operation - Page 14/Diagram 16 details a mono bridge set-up. Be sure your amplifier and all other audio equip- ment is powered down. Connect your speaker across the red output binding post on the rear of your amplifier. Turn your equipment on (your amplifier should always be the last item you turn on). Use the channel one gain to regulate your amplifier output. Bridged-Mono Mode Caution - The voltage across the output terminals of a bridged V5000plusTM amplifier may equal or exceed 100 volts RMS and may be as high as 130 volts. Use fully insulated CLASS ONE wiring, and the load must be rated for up to 2500 watts (@4 ohms) 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. 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 V5000plusTM 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 "MONO. " Be sure the amp is off or the power is disconnected before making any changes. 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, mono, 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. Use the frequency selector to adjust the subwoofer output frequency from 20Hz to 200Hz.
