[. . . ] Whether you need a small powered mixer for your Saturday afternoon "jam" or a professional full-size concert system, Fender has the sound reinforcement gear to meet your needs. Likewise, your decision to purchase quality Fender Professional Audio Equipment is one you will appreciate with each performance for years to come. Wishing you years of enjoyment and a heartfelt thank you, Bill Schultz Bill Schultz Chairman of the Board Fender Musical Instruments Corporation MK III PROFESSIONAL LOUDSPEAKER SYSTEMS INTRODUCTION All Wood Construction with Sturdy Dado Joints High Current 1/4" Phone Jacks and Neutrik SpeakonTM Connectors Titanium Diaphragm Horn Active / Operation Passive Crossover Thank you for purchasing a Mk III Series Loudspeaker System from Fender® Pro Audio. We are sure you will find it both a unique and effective sound reinforcement product, providing years of troublefree service day in and day out. [. . . ] Mk III Series Loudspeaker Systems are professional, fullrange, two-way, compact loudspeakers designed for the most demanding permanent or portable sound reinforcement requirements. Moreover, these speakers are ideal for use as a two-way system or as the mid / high pack in a three-way set-up incorporating a Fender subwoofer loudspeaker system. With a wide response, low distortion and controlled directivity, Mk III Series Loudspeaker Systems are designed to form the basis of everything from a small public address system to the nightly rigors of a "working band's" sound system. After moisture sealing, the Mk III Loudspeaker cabinets are covered in tough black indoor/outdoor synthetic carpet covering. Likewise, Mk III Loudspeaker cabinets also feature metal corners and rubber feet for a longer life and lasting looks. Only the finest components are used to provide maximum efficiency and response. In order to more fully understand the operational characteristics of your Mk III Series Loudspeaker enclosure, please read through this operational user's guide. Metal Corners and Rubber Feet Tough Indoor / Outdoor Synthetic Carpet Covering CAUTION: Almost all speakers produce strong magnetic fields which may interfere with the normal operation of nearby electronic devices, including televisions and computer video monitors. To reduce or eliminate interference, increase the distance between this product and other nearby electronic devices. 3 SPEAKER WIRING AND CONNECTIONS Parallel or series are the two basic ways which multiple speakers can be connected to a single power amplifier. When speakers are connected in parallel, their combined impedance decreases. For speakers wired in series the opposite is true, their combined impedance increases. Thus, an external crossover must be used with the speaker and two channels of power amplification will be required: one for the low frequencies and another for the high frequencies. In bi-amp mode, the connections are as follows: Phone Jacks Frequency Lows Lows Highs Highs Polarity Positive (+) Negative (-) Positive (+) Negative (-) Left N/A N/A Tip Sleeve Right Tip Sleeve N/A N/A Speakon 1+ 12+ 2- I Mk II et bin Ca Stage Mk CabinIII et Audience Two speakers arranged as a mono or stereo pair requiring maximum horizontal coverage 30º Mk III Cabinet Mk III Cabinet IMPORTANT: If the crossover switch is set to external, DO NOT plug a full range signal into the High Frequency input. Doing so will destroy the compression driver. Two speakers in a "loose pack" array requiring maximum horizontal coverage NOTE: When setting up your Mk III Series enclosures, be sure to place the cabinets in such a way as to minimize overlapping radiating patterns. A second consideration is for feedback and bass performance. If the speaker is placed near a large, flat wall, the bass output will increase by approximately 6 dB. A third consideration is to what degree the speaker should be "heard and not seen", especially in permanent installations. Remember, where the speaker cabinets are placed will effect both their tone and radiating patterns. 5 BI-AMP OPERATION For versatility and increased headroom, some users may choose to use an active electronic crossover / processor, such as the Fender PCN-2 or PCN-4, with the system. The electronic crossover takes the place of the internal crossover of the speaker system. The "Normal / Bi-Amp" switch on the back of the cabinet must be set to the "Bi-Amp" position. Always check to ensure the internal/external crossover switch which selects passive or biamp operation is in the correct position prior to use. [. . . ] The "Normal / Bi-Amp" switch on the back of the cabinet must be set to the "Bi-Amp" position. Always check to ensure the internal/external crossover switch which selects passive or biamp operation is in the correct position prior to use. For those situations requiring a subwoofer, Mk III loudspeakers can still be used if a three-way electronic crossover is used. It is strongly recommended that a fourth-order "Linkwitz-Riley" or a digital FIR fourth-order active crossover be used. [. . . ]
