DC-3Operating Instructions

Overview:

Your DC-3amplifier was designed to deliver maximum performance in a format based on simplicity. Its easy to dial nature allows each of the two channels to deliver a wide range of sounds in both clean and overdrive styles. This Dual Caliber uses four EL-84 power tubes to fuel its healthy thirty-five watt power section. We are pleased by its surprising headroom, yet truly musical “clipability” when pushed. The DC-3’spre-amp was no afterthought as you may have deduced by the six 12AX7s tucked snugly away under the swing away tube clamp. Two separate sets of tubes are used to accomplish the Rhythm and Lead channels. It’s really like having two separate amplifiers built into one chassis. Ultimate flexibility is achieved by providing two complete sets of Tone and Master controls as well as the channel assignable 5 Band Graphic Equalizer. Two different sounds can be switched between without compromising tone or levels.

Looking to the Rear Panel assures that all your interfacing needs are covered. A parallel effects loop with a mix control provides tone insurance for even those questionable effects. A recording circuit dialed for direct to board sessions provides accurate reproduction of the DC-3’spre-amp. When the session goes late into the night, the silent recording Speaker Mute switch comes in real handy. To use the DC-3in larger rack systems, or to interface to other power sections, the Slave Jack and Level Control are welcome features. Three speaker jacks (one 8 ohm, and two 4 ohm) are provided to ensure the proper impedance match to many types of speaker enclosures. An auto assign EQ rotary control lets you decide whether the 5-Band graphic enhances the Rhythm Channel, the Lead Channel, both, or even allows footswitching of the EQ independently. The Reverb can also be footswitched in or out.

As you can see, the DC-3provides all the features any demanding pro could need and at the same time remains simple to operate.

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.
