OUTPUTS: Binding Post/Banana Plug - Connect your speakers to the binding post outputs on the rear of the amplifier. The speaker wire may be connect by bare wire (directly connected, usually for permanent connections), banana plug, or spade connector. Connections are made to Channels 1 and 2 output’s for stereo mode or across the red termi- nals of Channels 1 and 2 for Mono Bridge Mode. Important Notice: Although a speaker will operate with the positive and negative leads plugged into either termi- nal on the amplifier binding post, be sure to plug the negative lead into the black terminal and positive lead into the red terminal. Ensuring proper polarity will avoid speakers being out of phase, that can cause a loss of bass response. Important Notice: Banana Plugs - When connecting your speakers to the amplifier using banana jacks; Be sure that the red and black caps on the binding post are completely screwed in. Insert the banana jacks into the caps of the binding post, be sure that the banana jack is inserted securely to avoid the risk of it popping out. Diagram 6 ©American Audio® - www.americanaudio.com - V5000plus™ Power Amplifier User Manual Page 7 Set Up INPUTS - The V5000plus 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 V5000plus 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. For cable runs shorter than 20ft. you may choose the 1/4” unbalanced input option. The 1/4” unbalanced input option may be more convenient for most users due to the abundant supply of prefabricated cables available at your local audio dealer. You may use the two XLR “Input Thru” jacks to jump a parallel connection to another amplifier or other device. For Example: Connect a XLR cable to the input of channel one. You may now connect a XLR cable from the channel one “Input Thru” jack to the input jack of another amplifier’s channel one input. This will reduce the use of “Y” cables. �������������������� Hot(+) Negative(-) Diagram5 ������������������� Ground/ShieldHot(+) Negative(-) Diagram4 2Hot(+data) 3Negative(-data) 1Ground/Return/0v) 1 3 2 ����������������������� USITTStandard Diagram3
Spade Connector: (Diagram 8) When connecting your speakers to the amplifier using spade connector; Unscrew the red and black caps on the binding post, be sure not to completely remove or unscrew the red and black caps. Insert the spade con- nector in to the binding post and tighten the caps down on the spade connector. To reduce the risk of shock or damage to your amplifier, be sure that the wire connected to one binding post does not come in contact with that of another. When connecting your speakers to the amplifier using banana jacks; Be sure that the red and black caps on the binding post are tighten down completely. Insert the banana jacks into the caps of the binding post, be sure that the banana jack is inserted securely to avoid the risk of it popping out. Mono Bridge Connections: Mono bridge operation connections will follow the above descriptions however, when operating in mono bridge operation the speaker connections will run between the two positive (red) leads. Use channel two pos- itive output terminal for the negative connection and the channel one positive output terminal for the positive connection. Typical speaker output using spade connectors. Insert bare wire into the binding post and tighten. Diagram 8 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 plugs 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.americanaudio.com - V5000plus™ Power Amplifier User Manual Page 8 Bare Wire Connections: (Diagram 7) 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. To reduce the risk of shock or damage to your amplifier, be sure that the wire connected to one binding post does not come in contact with that of another. Typical speaker output using bare wire. Insert bare wire into the binding post and tighten. Diagram 7
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 diagram 9. 2. Slide the cable tension clip (D) and the speakon coupler (E) through the cable end. See diagram 10. 3. Insert each wire with the brass fittings into the top of appropriate slot of the connector insert (B) as shown in diagrams 10 and 11. Use a 1.5-mm Allen key to tighten the connection. See diagram 11. 4. Be sure to properly match the positive (+) and negative (–) leads of each wire. See diagram 12. 5. Slide the connector insert (B) into the connector housing (A), making sure that the large notch on the outer edge of the insert lines up with the large groove on the inside of the connector housing. The insert should slide easily through the housing and out the other side until it extends approximately 3 /4-inch from the end of the housing. 6. Slide the cable tension clip (D) along the cable and insert into the housing (A), making sure that the large notch lines up with the large groove on the inside of the connector housing (A). The cable tension clip (D) should slide easily into the housing until only 3 /8-inch of the cable tension clip (D) extends from the back end of the connector. 7. Slide the coupler (E) along the cable and screw it onto the end of the housing (A). Before tightening, you may want to test the connector to make sure it has been assembled properly. ©American Audio® - www.americanaudio.com - V5000plus™ Power Amplifier User Manual Page 9 Diagram9 ����������CAUTIONMINIMUMLOADIMPEDANCE2OHMPERCHANNEL4OHMBRIDGE������������������ �������������SPEAKON1+HOT1COLD��������������� � + +1 -1 +2 +2 ++1 -1 +2 +2 Diagram12 Diagram11 4-ConductorSpeakerCableBrassInserts Diagram10 DEBAC
©American Audio® - www.americanaudio.com - V5000plus™ Power Amplifier User Manual Page 10 OPERATING MODES: Always configure your amplifier operating mode before beginning operation. If you want to change it dur- ing performance. 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. 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-clockwise). 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/Diagram 16 details a mono bridge set-up. Be sure your amplifier and all other audio equip- ment is powered down. Flip the Stereo/Mono Bridge switch to the Mono Bridge position. 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 V5000plus™ 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 V5000plus™ 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. Also, set the subwoofer mode switch to the subwoofer position. Use the frequency selector to adjust the subwoofer output frequency from 20Hz to 200Hz. The different subwoofer modes are listed as follows; Bridge Subwoofer - This operation allows you to get the most possible power out of your amplifier for the sole purpose of running a high powered subwoofer loudspeaker in mono. To avoid amplifier overheating, never run the amplifier below 4 ohms in this mode. In this mode you may use the frequency adjustment on the rear of the amp, to control the frequency output level. Frequencies may be adjusted from 20Hz to 200Hz. Page 13/ Diagram 13 details a typical Bridge Subwoofer set up. Stereo Subwoofer - This operation is similar to the Bridge Subwoofer operation but in stereo. This operation allows you to run several subwoofers down to a minimum of 2 ohms. To avoid amplifier overheating, never run the amplifier below 2 ohms in this mode. Set up this mode as you would a standard stereo set up. Be sure both channels are set to “SUBWOOF.” In this mode you may use the frequency adjustment on the rear of the amp, to control the bass frequency output level. Frequencies may be adjusted from 20Hz to 200Hz. Page 13/ Diagram 14 details a typical Stereo Subwoofer set up.
