Set Up INPUTS - The VLP Series amplifier allows you to use two types of input connector per a channel, a XLR jack for balanced connections and a 1/4” female jack that will accept balanced and unbalanced connectors. Use these connections to connect the output signal from a mixer, cross-over or EQ to your VLP Series amplifier. A balanced connection is recommended for cable runs longer that 20ft. When constructing your own XLR cables follow the pin configuration describe below for proper connections.
Bare Wire Connections: (Figure 11) When connecting your speakers to the amplifier using bare wire; Unscrew the red and black caps on the binding post, be sure not to completely remove or unscrew the red and black caps. Strip back the wire insulation 1/2” (13mm). Insert the bare wire into the hole that was reveled by unscrewing the binding post cap. After inserting the wire into the binding post hole, screw the binding post cap down on the wire.
Speakon Assembly: You will need a pair of Neutrik Speakon® NL4FC connectors. You will also need high-quality two or four conductor speaker cable, a pair of needle-nosed pliers and a 1.5-mm Allen key to assemble the Speakon connectors to your speaker wire. To assemble the Neutrik Speakon NL4FC connector, complete the following steps: 1. Strip back 3/4-inch of the cable casing. Strip off 1/4-inch from the end of each of the conductors down to bare wire, and insert the brass fittings. See Figure 13. 2.
Operating Modes: Always configure your amplifier operating mode before beginning operation. If you want to change it during performance. You must decrease the gain controls to their lowest levels to protect the speakers from any popping noise. Stereo Operation - Page 17/Figure 17 details an example of a typical stereo set-up. Connect your inputs into channels one and two of the amplifier. Connect your speakers to the outputs on the rear of the amplifier.
Mono Subwoofer - This operation is similar to the Stereo Subwoofer operation but in mono. When running subwoofers it is usually recommended to run them in mono mode to achieve a cleaner tighter low end. This operation allows you to run several subwoofers down to a minimum of 4 ohms. To avoid amplifier overheating, never run the amplifier below 8 ohms in this mode. Set up this mode as you would a standard stereo set up.
put). Short Circuit Protection can usually be traced back to the signal output line (i.e. speaker line). Check the line from the output terminal of the amplifier to the speaker. If this line good, check the internal speaker connections and components. A short circuit will usually be traced to a bad cable or a bad speaker component and is rarely traced to the amplifier itself. Thermal Protection - Dual variable speed fans on the VLP Series amplifier provide adequate cooling.
