A Message from the Chairman At Fender, we know the importance of sound reinforcement. From the simple box-top powered mixer to today’s touring concert systems, the need to communicate to make the connection between the performer and the audience is foremost in our mind. Perhaps no other piece of gear can make or break your message or your band’s sound than your sound reinforcement gear. Your sound system is far more than just a combination of dials, wires and speakers. It is an integral part of the audio chain and should be treated with special care and attention to detail. Fender knows what building quality musical instruments and sound reinforcement equipment is all about. In fact, many of the world’s best sounding electric musical instruments and sound reinforcement equipment proudly wear the Fender name. 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 1272X / 1275X 1272X / 1275X1272X / 1275XLOUDSPEAKER MONITOR LOUDSPEAKER MONITORLOUDSPEAKER MONITORSYSTEMS SYSTEMSSYSTEMS INTRODUCTION All Wood Construction with Sturdy Dado Joints High Current 1/4” Phone Jacks Metal Corners and Rubber Feet Level Control for Adjusting Levels at the Cabinet Three Angles of Orientation: 30., 60. and Vertical for Side Fill Use Tough Indoor / Outdoor Synthetic Carpet Covering Thank you for your purchase of a 1272X / 1275X loudspeaker monitor system from Fender® Pro Audio. We are sure you will find it both a unique and effective sound reinforcement product, providing years of trouble-free service day in and day out. 1272X / 1275X loudspeaker monitor systems are professional, full-range, two-way, compact loudspeaker monitors designed for both permanent or portable sound reinforcement requirements. With a wide response, low distortion and controlled directivity, 1272X / 1275X loudspeaker monitor 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 1272X / 1275X loudspeaker monitor systems are covered in tough black indoor/outdoor synthetic carpet covering. Likewise, 1272X / 1275X loudspeaker monitor systems 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 1272X / 1275X loudspeaker monitor system enclosure, please read through this operational user’s guide. 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 SPEAKER WIRING AND CONNECTIONS Parallel orseries 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, when speakers are wired in series, higher impedance speakers in the series draw more power from the amplifier than do speakers in the series with lower impedances. When speakers are wired in parallel, the opposite is true. Higher impedance speakers will draw less power from the amplifier than lower impedance speakers will draw. At Fender®, we recommend connecting multiple speakers in parallel for several reasons. First, if one speaker fails, the others will continue to operate. Second, because in a series connection one speaker affects the Keep in mind, power and audio signal cables are the most common sources of sound system failure. Well made and carefully maintained cables are essential to the reliability of the entire sound system. If long speaker cables are required, it is important to ensure the cable‘s gauge is sufficient to transfer all of the available amplifier power to the speakers rather than absorbing the power itself. As a rule of thumb, larger wires are better as they conduct more power to the speakers (larger wire has smaller gauge numbers). Below are two charts listing speaker wire gauges and recommendations for best results.
