EFFECTS LOOP

Two pairs of Send and Return jacks are provided, one pair on the front and one pair on the back of the D-180. So whether you use effects devices on the floor or built into a rack, patching with your D-180 is convenient and precise. The sophisticated Effects Loop circuitry of the D-180 works extremely well. A low impedance "send" amplifier assures high intercompatibility plus low noise. A unique Blend control located on the upper rear amplifier chassis (where it won't get-broken or damaged) enables you to mix "dry" and effected signals. With the Blend knob set at 10, all signal will pass through the accessory effects; set at 5, about half of the D-180 signal will pass through the effects and half will go direct. Set at 0, the effect patch points are fully bypassed. Zero is the recommended setting when no effects devices are patched into the loop. The Effects Send level has been padded at the rear panel jack to accommodate low-headroom effects devices. The front panel Send jack is unpadded.

The Effects Return jack offers access directly into the D-180's power stage, and about .775 volts (or 0 dBv) is required to drive it to full power when the Master is set at ten. This exactly matches the input sensitivity of the M-180 basic power amplifier (no preamp or control sections) so, by driving the M-180(s) from the Effects Send of the D-180, automatic level balancing will be maintained between all amplifiers. But if distortion from the D-180 is being used, or if heavy effects processing is in the loop, the 600 ohm balanced out or the Slave Output would be preferable. These features are described below.

D-180 specifications

The Mesa/Boogie D-180 is a powerful and versatile guitar amplifier that has captured the attention of musicians since its introduction. Known for its rich tones and robust build, the D-180 is designed to meet the needs of both studio recordings and live performances.

One of the standout features of the D-180 is its all-tube design. Utilizing a combination of 6L6 and 12AX7 tubes, the amplifier produces warm, harmonic-rich sounds that are characteristic of vintage tube amplifiers. This design not only enhances the tonal quality but also provides the dynamic response players seek, allowing for expressive playing that responds to the nuances of their technique.

The D-180 boasts a unique power section with 180 watts of clean headroom. This immense power allows for a wide range of tonal versatility, from crystalline clean tones to fat, saturated overdrives. The amp’s ability to transition smoothly between these tones makes it a favorite among guitarists who require a reliable workhorse for various musical styles, including rock, blues, and jazz.

Additionally, the D-180 features a unique "Simul-Class" technology that combines both Class A and Class AB operation. This innovative design results in a more efficient power usage without sacrificing tone or feel. As a result, players enjoy the punchy response of a Class A amp while retaining the headroom that Class AB provides.

The D-180 also includes a comprehensive EQ section with a three-band equalizer, which allows players to sculpt their sound precisely. The presence and depth controls further enhance tonal shaping, offering substantial adjustment to the overall character of the amplifier. This level of control makes it easy for users to dial in their ideal sound, whether they are in the studio or on stage.

Another significant aspect of the D-180 is its rugged construction. Built with high-quality components and a sturdy chassis, this amplifier is made to withstand the rigors of touring. Its reliability has made it a top choice for professional musicians who need equipment that can handle long hours of performance without any compromise on tone or function.

In conclusion, the Mesa/Boogie D-180 is a formidable amplifier that stands out for its all-tube design, powerful output, innovative Simul-Class technology, and extensive tonal shaping capabilities. Its rugged build and reliability make it a trusted companion for guitarists across genres, solidifying its place in the pantheon of quality amplifiers.
