This symbol is intended to alert the user of the presence of important operating and maintenance (servicing) instructions in the literature accompanying the product. WARNING: To prevent electrical shock or fire hazard, do not expose this amplifier to rain or moisture. [. . . ] Use channel two positive output terminal for the negative connection and the channel one positive output terminal for the positive connection. Diagram 11 Typical speaker output using spade connectors. Insert bare wire into the binding post and tighten. Stereo Connections Using the Neutrik Speakon output connectors: Recent regulatory requirements in Europe have outlawed the use of the dual banana plug and force amp users to terminate their speaker cables with spade lugs or bare wire ends. This is not advantageous to most users that want to reconfigure their systems or quickly change out an amp. The Neutrik Speakon® connector provides the most convenient solution to this problem, eliminating the need for spade lugs or bare wire end cables. Major speaker manufacturers have been using Speakon connectors on their products for years, so chances are you are ready to use the Speakon connection. With Speakon connectors, you can connect straight from the amplifier to the speaker. The Speakon connector used on this amplifier meets all known safety regulations. Once wired correctly, the connector cannot be plugged in backwards, causing the type of inverted polarity situations that have become common with banana hookups. This connection will provide a safe, secure and reliable method of connecting your speakers to your new amplifier. You can purchase the Speakon® NL4FC connectors from your local audio dealer. ©American Audio® - www. americandj. com - V4000plusTM Power Amplifier User Manual Page 8 OPERATING MODES: Always configure your amplifier operating mode before beginning operation. You must decrease the gain controls to their lowest levels to protect the speakers from any popping noise. Stereo Operation - Page 10/Figure 9 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 9/Figure 8 details a mono bridge set-up. Be sure your amplifier and all other audio equipment 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 V4000plusTM amplifier may equal or exceed V4000 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 V4000plusTM to run bass V4000 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. [. . . ] One channel can still operate normally if the other goes into overheat protection mode. 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. [. . . ]
