Page 5: Dual Caliber Dc
DC-5 Overview: Your DC-5 amplifier 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. The Dual Caliber uses two 6L6 power tubes to fuel its healthy fifty watt power section. -

FRONT PANEL: First familiarize yourself with the layout of the Front Panel and locate the Lead / Rhythm switch on the right side of the chassis, next to the STANDBY Switch. This toggles you between the top (Rhythm) Channel and the bottom (Lead) Channel. If you don’t have the Rhythm/Lead Footswitch connected, this switch will activate the channel switching function. -

CONTROLS: (Continued) GAIN (continued) example, somewhere between Use of moderation here will reduce the likelihood of pesky tube microphonic problems ever occuring, while at the same time making the two channels easier to balance in volume and effects send strength.

CONTROLS: (Continued) BASS This control blends in the lower frequencies and its effectiveness, again, depends on the setting of the TREBLE Control. It should be set with moderation as extreme settings in either low or high directions can produce an unbalanced tone. Be “especially” careful in INPUT PULL BOOST... -

CONTROLS: (Continued) MASTER (continued) When using the direct Recording jack found on the Rear Panel to interface directly to a mixing board or recorder, this control will determine the amount of signal you will be sending via this jack. In this application it is usually best to start with the MASTER Controls set to and gradually increase them to the proper level. -

CONTROLS: (Continued) OUTPUT LEVEL: This lonely knob is the DC-5’s final Output knob or overall master. After the relative balance of the two channels has been set with the channel MASTER controls, use this OUTPUT control to increase or decrease the listening volume. It is also the effects return level RHYTHM OUTPUT LEVEL... -

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. -

4X12 cabinets may be 4, 8 or 16 ohms; if you are not sure of the impedance of your cabinet, you may need to remove the rear panel to see what the ohmage of the individual speakers are. MESA/Boogie 4X12 cabinets come standard wired to 8 ohms. They have four 8 ohm speakers wired in series-parallel. -

Page 16: Tube Noise & Microphonics
TUBE NOISE & MICROPHONICS You may occasionally experience some form of tube noise or microphonics. Certainly no cause for alarm, this quirky behavior comes with the territory and the Tone. Much like changing a light bulb, you don’t need a technician to cure these types of minor user serviceable annoyances and in fact, you’ll be amazed at how easy it is to cure tube problems...by simply swapping out a pre-amp or power tube! First may we suggest that you set the amplifier up on something so that you can get to the tubes comfortably without having to bend... -
Page 17: Diagnosing Pre-Amp Tube Problems
DIAGNOSING PRE-AMP TUBE PROBLEMS: Because your amplifier is an all tube design, it is quite possible that you will at some point experience minor pre-amp tube noise. Rest assured - this is no cause for alarm and you can take care of the problem yourself in a matter of minutes by simply swapping tubes. Let us begin by saying;... - Page 18 BIAS ADJUSTMENT: (Part of a continuing series) NOTE: An article written by Randall Smith that we thought you might find interesting. Here’s a question we often hear: “Why doesn’t Mesa put bias adjustments in their amplifiers?” Well, there’s a short answer and a long answer to this question. The short answer is that during my 12 years of repairing Fenders, one of the most frequent problems I saw was bias controls that were either set wrong or that had wandered out of adjustment due to vibration.

Page 19: Bias Adjustment, An Article By Randall Smith
BIAS ADJUSTMENT (Continued) Voltage and current are NOT the same. Current is the AMOUNT of electricity, the “quantity” — and is measured in amperes. Voltage is the degree of electric charge — like the “pressure” to use the old water analogy. Let me illustrate how different voltage and current are: When you scrape your feet across a carpetted floor in dry, wintery conditions, your body can become charged with 50,000 to 100,000 volts of static electricity. - Page 20 How much money and trouble that has saved Mesa/Boogie players you couldn’t estimate.
