ATTENTION: POUR EVITER LES RISQUES DE CHOC ELECTRIQUE, NE PAS ENLEVER LE COUVERCLE. [. . . ] Since these two inputs are in parallel, you shouldn't connect more than one source to the INPUT A or INPUT B jacks. However, you can use the unused input jack as a "Thru" connector, to daisy-chain the signal to another amplifier. See "Input Wiring" on page 10 for information on input connection wiring. GENERAL PRECAUTIONS AND CONSIDERATIONS Rack Mounting The Juice amplifiers are designed to be mounted in a standard rack. They also require 15. 75" depth inside the rack, including the rear support brackets. When designing your rack, put the heavier items at the bottom and the lighter items toward the top. Secure the front panel of the amplifier to the front of the rack using four screws with soft washers to prevent scratching the panel. In addition, because of the weight of the amplifier, you must secure the rear support brackets of the amplifier to the back of the rack. You could use a support rail or shelf across the back of the rack, or angle brackets attached between the rear support rails and the rear rails of the rack. This is recommended for all components mounted in a rack that is going to be moved frequently (or thrown in the back of a pickup truck and transported down a bumpy gravel road to that outdoor festival!). 9. SUBSONIC FILTER Turn this switch on to engage a low-frequency cutoff (high-pass) filter at 30 Hz. The Juice amplifiers can amplify signals below 20 Hz, but most speakers can't reproduce frequencies that low. By engaging the SUBSONIC FILTER, you allow the amplifier to power only the frequencies that you can hear. In addition, this filter can remove low-frequency stage noise (footsteps) and accidental microphone pops that could damage a loudspeaker. 9 Thermal Considerations The Juice amplifiers are fan-cooled with two separate fans. One fan brings cool air in from the back and the other fan blows the warm air out the front of the chassis. Make sure that cool air is available at the back of the amplifier, and that there is room in the front for the warm air to exit from the amplifier and dissipate. As the power output increases and the amp warms up, the fans gradually increase in speed to provide additional cooling. use a high-quality 2-conductor shielded cable. Your TAPCO Dealer can recommend a suitable cable for your application. When connecting a balanced signal, the connectors are wired thusly, according to the AES (Audio Engineering Society) standards: XLR Pin 2 Pin 3 Pin 1 TRS Tip Ring Shield SHIELD HOT Hot (+) Cold (­) Shield (Gnd) 2 AC Power Considerations Be sure the amplifier is plugged into an AC outlet that is able to supply the specified voltage. Be sure the AC outlet can supply enough current to allow full power operation of all the amplifiers plugged into it. The outlet should be a three-prong socket that matches the power cord. WARNING: Bypassing the plug's safety ground pin can be dangerous. Don't do it!
