User manual AMERICAN AUDIO V1500

[. . . ] Read all documentation before attempting to operate your new amplifier. Be sure that the local power outlet match that or the required voltage for your amplifier. Do not attempt to operate this unit if the power cord has been frayed or broken. Do not attempt to remove or break off the ground prong from the electrical cord. [. . . ] In protect mode the output signal to the speakers will terminated to channel two. Channel 2 Signal indicator This Green LED will glow when there is an input signal present. Channel 1 Gain control This knob adjust the channel one volume output to the speakers connect to channel one. Channel 2 Gain control This knob adjust the channel one volume output to the speakers connect to channel one. Exhaust Cooling Vents A cooling fan is mounted at rear of the amplifier. These exhaust vents allow hot air to be pushed out of the amplified to allow ample cooling of the internal components. Do Not Block These Vents!

Channel 1 Input Connect the input source for channel one to either the balance XLR or the unbalanced 1/4" input jacks. Channel 2 Input Connect the input source for channel two to either the balance XLR or the unbalanced 1/4" input jacks. This fan is used to cool the internal parts of the amplifier when in use. Never block the fan in any way or mount in an enclose rack, doing so may cause the amplifier to overheat and fail. A/C Power Input Plug this cable in to a standard 110~120v wall outlet. Be sure that supplied voltage matches that of the required voltage of you amplifier. Never plug your amplifier in to a wall outlet that does not match the required voltage of your amplifier, serious damage 8 9 may occur to your unit. Channel 1 Speaker Output - 5 Way Binding Post Connect your channel one speakers to channel one output. Channel 2 Speaker Output - 5 Way Binding Post Connect your channel two speakers to channel two output. Mono-Bridge/Stereo Selectable Switch This push button switch changes the amplifier operating mode from either stereo or mono bridge. All way replace with exact same type fuse unless otherwise instructed to do so by an authorized American DJTM service technician. Ground Lift Switch This switch is used to disconnect the internal ground signal from the chassis ground. This may reduce the buzz that is caused from an electrical 60Hz cycle. V1500TM Power Amplifier Instructions page 5 INPUTS The V1500TM allows you two types of input connector per a channel, a XLR jack for balanced connections and a 1/4" jack for unbalanced connections. Use these connection to connect the output signal from a mixer, cross-over or EQ to your V1500 amplifier. When building your own XLR cables follow the pin configuration describe below for proper connections. [. . . ] An ultrasonic network decouples RF from the output and helps keep the amplifier stable with reactive loads.
