FUSE:

This is the A.C.’s (Alternating Current) main fuse and provides electrical current protection from outside A.C. fluctuations, as well as power tube failure damage. Should the FUSE blow, replace it with the same rating in a slo-blo type package. The domestic U.S. version requires a 2.5 amp slo-blo fuse. A power tube short or failure is often the cause of a blown fuse...Follow the cold start procedure mentioned in the ON/STANDBY switch section and watch the four EL-84 power tubes as you flip the STANDBY switch to the ON position. If a power tube is going bad or is arcing you will see it! Flip the STANDBY switch to Standby immediately and replace the faulty power tube and the FUSE if necessary. If you see nothing abnormal as you lift the STANDBY switch, it is possible that a power tube shorted temporarily and blew the FUSE. If this is the case it may work again normally. To be extra safe you may want to replace all four power tubes in the “shotgun” troubleshoot-

ing tradition and save the replaced set as spares.

NOTE: Like tires on a car, spare tubes are always a measure of good insurance. Your DC-3was carefully constructed with reliability in mind! Given the proper care and maintenance, it will deliver years of trouble free service. However, any pro guitarist who is out there gigging will tell you; spare tubes are a must for the fabled cord bag and may someday be worth their weight in gold. Spare fuses are also a very easy way to insure an uninterrupted performance.

EQ SELECT:

As we mentioned earlier in the Graphic EQ section, this rotary control is used to select the assignment of the 5 assignment of the 5- Band Equalizer. See Graphic EQ section on page 5 for an explanation of the 5 possible positions of this rotary control.

FTSW EQ/REV:

This 1/4" Stereo jack allows you control of the EQ and Reverb remotely when a Stereo cable and Mesa Dual Footswitch are connected. This footswitch is an option and can be ordered by calling us direct, or by contacting your nearest Mesa/ Boogie Pro Center.

DC3 specifications

The Mesa/Boogie DC-3 is a highly regarded guitar amplifier known for its versatility, power, and distinctive tone. Introduced during the early 1990s, the DC-3 has become a staple among musicians who appreciate its unique blend of classic and modern sounds. The amplifier is part of the Mark series, renowned for its innovative design and exceptional sound quality.

One of the standout features of the DC-3 is its all-tube preamp, which contributes to its warm and rich tonal characteristics. The amplifier utilizes three 12AX7 tubes in the preamp stage, providing a dynamic response that enhances the natural tonal qualities of the guitar. This all-tube configuration is complemented by a powerful 2x6L6 power tube setup, delivering a powerful 30 watts of output. This combination allows the DC-3 to produce a wide range of tones, from clean and sparkling to thick and saturated drive.

The DC-3 is equipped with a unique two-channel design, offering a Clean channel and a Lead channel, each with its own set of controls for ultimate tonal shaping. The Clean channel is characterized by its bright and articulate sound, making it suitable for a variety of genres, including jazz, pop, and rock. The Lead channel, on the other hand, offers greater gain and sustain, perfect for heavier styles like hard rock and metal. These channels can be blended together using the shared EQ, allowing for a truly customizable sonic experience.

Mesa/Boogie's innovative graphic equalizer further enhances the versatility of the DC-3. It features a five-band EQ that allows players to sculpt their sound with precision. This feature makes it easy to dial in the perfect tone for different performance environments, whether in the studio or on stage.

The DC-3 also includes a built-in reverb, adding depth and ambience to the overall sound. This is a valuable addition for musicians looking to enrich their performances without the need for additional effects pedals.

Robust construction and attention to detail are hallmarks of Mesa/Boogie amplifiers, and the DC-3 is no exception. It is built to withstand the rigors of touring and the demands of professional musicians. With its impressive tonal palette, reliable performance, and durable design, the Mesa/Boogie DC-3 continues to be a favorite among guitarists, making it a worthy investment for anyone serious about their craft.
