Stereo operation -
page 14/Figure 13 details an example of a typical stereo set-up. enter into the menu and go to the mode set-
ting, set the amp to Stereo and press enter. connect your inputs into channels one and two of the amplifier. connect your speakers to
the outputs on the rear of the amplifier. Be sure that your front gain controls are turned down to their lowest level (full counter-clock-
wise). Turn your amp on. Turn your input source level up. use your front gain controls to regulate the output volume. Be sure not to
raise the volume to the clip level, however an intermittent clip signal is acceptable.
Mono Bridge operation -
Page 14/Figure 14 details a mono bridge set-up. Be sure your amplifier and all other audio equipment
is powered down. Enter into the Menu and go to the Mode setting, set the amp to Bridge and press Enter. Connect an input signal to
channel one. 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). Apply an input source signal to your amplifier. Turn channel two gain up. use the
channel one gain to regulate your amplifier output.
Bridged-Mono Mode Caution -
The voltage across the output terminals of a bridged vX Series™ 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. 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 vX Series™ 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. enter into the menu and go to the mode setting, set the amp to parrallel and press enter. Be sure the amp is off or the power is
disconnected before making any changes.
