NOTE TO CATV systems installer: This reminder is provided to call the CATV system installer's attention to Article 820-22 of the NEC that provides guidelines for proper grounding and, in particular, specifies that the cable ground shall be connected to the grounding system of the building, as close to the point of cable entry as practical. NOTA PARA EL INSTALADOR DE ANTENAS DE TELEVISION COLECTIVAS: La presente advertencia se provee para llamar la atenció n del instalador al Artí culo 820-22 de NEC (Có rdigo Elé ctrico Nacional) donde se facilitan las directrices para la pertinente puesta a tierra y que especifica en particular que el condutor a tierra del cable debe connectarse al sistema de conexió n a tierra del edificio, lo m á s proximo posible al punto de entrada del cable. The lightning flash with arrowhead, within an equilateral triangle, is intended to alert the user of the presence of uninsulated" dangerous voltage" within the product's enclosure; that may be of sufficient magnitude to constitute a risk of electric shock to persons. The exclamation point within an equilateral triangle is intended to alert the user of the presence of important operating and maintenance (servicing) instructions in the literature accompanying the appliance. Warning: This speaker shall not be placed in the close area during the operation so that the mains switch can be easily accessed by the user. Introduction Thank you for choosing the Studiophile DX4 professional desktop audio monitoring system. Top recording engineers and producers in studios around the world use M-Audio's Studiophile Series monitors. [. . . ] We recommend grounding the unused negative input, which can be done by wiring the ring and sleeve of the TRS plug together. 5 For balanced wiring, a three-conductor TRS plug is necessary. The input wiring of the TRS input connector is as follows: TRS TIP Signal positive (+) TRS RING Signal negative (­) TRS SLEEVE Signal ground (Shield) Note: Input from the TRS and RCA connectors is summed together, allowing both inputs to be used simultaneously. MID-BOOST SELECTOR SWITCH: This 2-position switch selects the Mid-Boost mode setting. The "Out" position setting produces a flat frequency response curve, while the "In" position provides an added boost in the mid-range frequencies. SPEAKER TERMINALS: The rear panel of both Left and Right Speaker enclosures contains a spring-action speaker terminal. The included speaker wire should be used to connect the terminal on the left speaker to the terminal on the right speaker. POWER RECEPTACLE: Accepts a detachable 2-circuit line cord in order to power the DX4 system. PRODUCT LABEL: Contains your DX4's model and serial number information. POWER SWITCH: This switch turns the DX4 system on and off. The On position is indicated by the white dot on the switch. SUB FREQUENCY PORT: This port aids in the reproduction of very low frequencies by discharging the frequencies below 60Hz. Installation In order to ensure optimal performance your DX4 system, please read carefully the following instructions before beginning installation. Precautions Handling: The DX4 speakers are packaged tightly within the box, so your attention is required when removing them. To avoid possible damage to the speaker, hold both sides of the unit (not the front or the back) in order to pull it out of the box. The speaker cones (the Woofer and the Tweeter) should not be touched in order to avoid damage even after they are removed from the box. Please do not touch the speaker cones (the Woofer or the Tweeter). Connections: Connect the RCA or TRS inputs of your DX4 unit to the corresponding computer sound card or game console outputs. We recommend that you use high-quality cables for input connections. Be sure the power of the DX4 is off and turn the volume of the DX4 down to a minimum before making the necessary connections. 6 Correct Power Operation: Since the DX4 contains amplifiers; it must be connected to a power outlet using the detachable AC cable that is provided. Before connecting power, please make sure that the voltage of the DX4 corresponds with the voltage you are going to plug the power cord in. - Use of improper voltage may result in hazardous conditions and/or damage to speaker components not covered by speaker warranty. Speaker Wire Connection Use the speaker wires included in the DX4 package to connect the Right and Left Speakers via the spring terminals. Connecting to a Computer Sound Card or Game Console Before connecting the DX4s, make sure that the device to be connected to the DX4, and to the DX4 system itself has been powered off. Plug the appropriate RCA, TRS or TS cable to the corresponding output connectors of the computer sound card or game console. 7 Setting the Mid-Boost EQ Switch This 2-position switch allows you to select either the "In" or "Out" Mid-Boost mode. The Out mode produces a flat midrange response for normal monitoring and listening conditions. The In mode will move the sound stage forward toward your listening position. 'Mid-Boost In' Placing the DX4 Placing the speakers is one of the most important considerations in accurately monitoring sound. [. . . ] CLEANING The appliance should be cleaned only with dry cloth. POWER SOURCES The appliance should be connected to a power supply only of the type described in the operating instructions or as marked on the appliance. POWER CORD PROTECTION Power-supply cords should be routed so that they are not likely to be walked on or pinched by items placed upon or against them, paying particular attention to cords at plugs, convenience receptacles, and the point where they exit from the appliance 13. POLARIZED PLUG Do not defeat the safety purpose of the polarized or groundingtype plug. [. . . ]
