User manual TAPCO JUICE E

[. . . ] Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including amplifiers) that produce heat. Do not defeat the safety purpose of the polarized or grounding-type plug. If the provided plug does not fit into your outlet, consult an electrician for replacement of the obsolete outlet. Protect the power cord from being walked on or pinched particularly at plugs, convenience receptacles, and the point where they exit from the apparatus. [. . . ] If you are using unbalanced inputs, 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 Hot (+) Pin 2 Cold (­) Pin 3 Shield (Gnd) Pin 1 TRS Tip Ring Shield SHIELD HOT 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. 2 COLD 3 1 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! 3 1 SHIELD COLD 2 HOT Balanced XLR Connector RING SLEEVE SLEEVE RING TIP TIP RING TIP SLEEVE Balanced 1/4" TRS Plug The AC current demand of an amplifier varies depending on several factors, including the load impedance, the crest factor, and the duty cycle of the program material. Under typical conditions reproducing rock music where musical peaks are just below clipping, the Juice amplifiers require the following average currents. J·800 = 5 A J·1400 = 7 A J·2500 =10 A It is recommended that a stiff supply of AC power be used because the amplifier places high current demands on the AC line. The more power that is available on the line, the louder the amplifier will play and the more peak output power will be available for cleaner, punchier bass. If you have more than one amplifier sharing an AC outlet, you should avoid turning them all on at the same time. Rather, sequence them on, one at a time, to prevent popping the circuit breaker (due to in-rush current). Unbalanced TS (Tip-Sleeve) lines can be accommodated via the TRS jack. Make sure the cord terminates with a TS plug (like a guitar plug), or if it is a TRS plug (like a headphone plug), make sure the ring is tied to the shield, preferably at the source. SLEEVE SLEEVE TIP TIP TIP SLEEVE Unbalanced 1/4" TS Plug If you set the AMP MODE switch to MONO or BRIDGE, use the INPUT 1 input only. 10 Using the 1/4" TRS INPUT 1s a "Thru" Connector Because the XLR connector and the 1/4" TRS connector are in parallel, you can use the 1/4" TRS jack as a "Thru" connector to pass the input signal on to another amplifier's input (see Figure below). Note: If you use an unbalanced 1/4" TS cable to daisy-chain the TRS input jack to another amplifier, you will unbalance the XLR input on the Juice amplifier. This negates the benefits associated with balanced lines and inputs.

This allows you to use INPUT 2 as a "Thru" connector to daisy-chain the input signal to another amplifier. Passive Speakers (Mackie C300s) Wire Length Up to 25 ft. Output Wiring Use heavy gauge, stranded wire for connecting speakers to the Speakon outputs jacks. As the distance between the amplifier and the speakers increases, the thickness of the wire should also increase.
