Ventilation -- This product should be situated so that its location or position does not interfere with its proper ventilation. For example, the Component should not be situated on a bed, sofa, rug, or similar surface that may block any ventilation openings, or placed in a built-in installation such as a bookcase or cabinet that may impede the flow of air through ventilation openings. 6. 7. PORTABLE CART WARNING Carts and stands - The Component should be used only with a cart or stand that is recommended by the manufacturer. A Component and cart combination should be moved with care. Quick stops, excessive force, and uneven surfaces may cause the Component and cart combination to overturn. WARNING -- To reduce the risk of fire or electric shock, do not expose this appliance to rain or moisture. 2 18. Exposure to extremely high noise levels may cause permanent hearing loss. Individuals vary considerably in susceptibility to noise-induced hearing loss, but nearly everyone will lose some hearing if exposed to sufficiently intense noise for a period of time. The U.S. Government's Occupational Safety and Health Administration (OSHA) has specified the permissible noise level exposures shown in the following chart. According to OSHA, any exposure in excess of these permissible limits could result in some hearing loss. To ensure against potentially dangerous exposure to high sound pressure levels, it is recommended that all persons exposed to equipment capable of producing high sound pressure levels use hearing protectors while the equipment is in operation. Ear plugs or protectors in the ear canals or over the ears must be worn when operating the equipment in order to prevent permanent hearing loss if exposure is in excess of the limits set forth here.

Before you begin, please make sure you read the Safety Instructions on page 2 and Getting Started on page 4. Your new TAPCO® amplifier is designed to set up quickly and operate easily. We know it's often seen as a sign of weakness to read a manual, along with asking for directions when lost, but maybe you can read the rest when nobody is looking. It is important to keep your receipt in a safe place, and not a bad idea to write your product information here for future reference (i.e., insurance claims, tech support, return authorization, etc.).

All Rights Reserved. 3 Getting Started The following steps will help you set up your amplifier, and get the levels just right. SETTINGS: 1. Be sure the amplifier's POWER switch is off. 2. Turn down both Level controls. 3. On the rear panel, set the SUBSONIC FILTER switch OFF and the CLIP LIMIT switch ON. 4. Determine which AMP MODE is best for your application: STEREO mode is the typical setup for amplifying stereo signals. INPUT A is routed to CHANNEL A output, and INPUT B is routed to CHANNEL B output. MONO mode is used for sending a mono signal to both outputs, with separately adjustable level controls. INPUT A is used in MONO mode (leave INPUT B disconnected). BRIDGE mode uses both outputs to double the power to one speaker (or set of speakers). INPUT A is used in BRIDGE mode (leave INPUT B disconnected and the B Level control turned down). NOTE: 4 ohms is the minimum speaker impedance you should connect to the amplifier in BRIDGE mode. See "Do the Math" in Appendix B for information on calculating speaker impedances. 5. Set the AMP MODE switch according to your application. 4. In STEREO and MONO modes, connect Speakon® connectors to the CHANNEL A and CHANNEL B speaker outputs. · The Speakon connectors are wired as follows: 1+ = hot (+ speaker terminal) 1­ = cold (­ speaker terminal). 5. In BRIDGE mode, use the center Speakon connector. · The BRIDGED Speakon connector is wired as follows: 1+ = hot (+ speaker terminal) 2+ = cold (­ speaker terminal). 6. Plug all the sound system components into suitable AC outlets, properly grounded and capable of delivering adequate current. 7. Make sure your signal source is powered up and delivering signal to the amp. 8. Turn the power amplifier's switch on. Verify that the POWER LED lights. 9. Slowly turn up both Level controls on the amplifier. You should hear music and see the SIG LEDs flashing. If the OL (Overload) LEDs are flashing, turn down either the Level controls on the amp or the source signal's output level controls (i.e., master faders), until the OL LEDs either blink occasionally or not at all. 10. For quieter listening, it is preferable to adjust the amp's Level controls rather than the source signal's output level (unless you have the source's control all the way up!). CONNECTIONS: 1. Using balanced cables, make connections from your mixer (or other signal source) MAIN OUT to your amplifier's INPUTs. 2. In STEREO mode, connect the cables from your signal source to the amplifier's INPUT jacks, either XLR or 1/4" TRS. · The XLR and TRS inputs for each channel are wired in parallel. · The balanced XLR inputs are wired as follows: Pin 1 = shield (ground) Pin 2 = hot (+) Pin 3 = cold (­) · The 1/4" TRS inputs are wired as follows: Tip = hot (+) Ring = cold (­) Sleeve = shield (ground) 3. In MONO mode and BRIDGE mode, connect one cable from the input source to INPUT A, and connect nothing to INPUT B. Things To Remember: · Never plug amplifier outputs into anything except speakers (unless you have an outboard box specifically designed to handle speaker-level signals). · Before making connections to an amp or reconfiguring an amp's routing, turn the amp's level controls down, turn the power off, make the changes, turn the power back on, and then turn the level controls back up. · If you shut down your equipment, turn off the amplifiers first. When powering up, turn on the amplifiers last. · Save the shipping box and packing material! You may need it someday. If not, it makes a great end table or hiding place for your cat. 4 BY J·2500 OL SIG OL SIG ON POWER OFF 0 -0 dB 30 0 -0 dB 30 A B INPUT B INPUT CONNECTION CAUTION TO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK, DO NOT EXPOSE THIS APPARATUS TO RAIN OR MOISTURE.
