sounds superior - or vice versa. Trust your ears! You will not cause damage to your speakers or the TIGRIS by mismatching. Experiment to obtain the most pleasing results! Spades or steel spring bananas, gold- or rhodium plated, are the preferred cable terminations. Spades may be stacked for bi-wiring, or you can use spades and bananas simultaneously. Bare wire should be dressed with solder to prevent strays and offer the binding post lugs a firm and even contact. Biwiring requires two pairs of binding posts on the speakers and runs separate leads to either set. Both leads connect at the amplifier, while the shorting straps or bars at the speaker terminals are removed. In theory, seperating the high- and low frequency driver elements in the loudspeaker reduces possible inter- ference caused by back EMF from the bass driver to the treble unit, but not all speaker designers agree. A definite side benefit is the increased current capability of doubling the amount of conductors. Before you spend extra money to add second runs of speaker cable, use your existing pair of speaker cable to run one speaker in mono and compare single- and bi-wire hook-up - testing speakers monaurally is actually the most exacting method to determine tonal changes and distortion artifacts because you remove the distrac- tions of stereo effects and imaging.

Hand-tighten the lugs first, then add a quarter turn with a small wrench if necessary. Do not overtighten! The threads on these posts are very fine, and automobile tire-like torque will strip them.

3-4 HOOK-UP OPTIONS:

A:Line Level Inputs - The TIGRIS offers four line level RCA single-ended inputs, with corresponding positions on the front- mounted input selector - CD, Tape, Aux 1, Aux 2. For convenience’s sake, these inputs have been labeled. Remember, however, that with the exception of a turntable, these inputs are fully interchangeable to accomodate the components that you wish to hook-up.

For example, if you do not presently own a CD player but have two tape decks, a tuner and a TV, you may connect those components without worry. You will only have to remember that the CD input now corresponds with the TV, tape II with Aux 1 - or however you have arranged your connections.

The inputs and outputs are arranged in two horizontal rows, with the left channel jacks, marked white, in the lower row and the right channel jacks, marked red, in the upper row. The two output terminals are the outermost left and right pairs, with all the input terminals inbetween. Each pair is clearly marked.

If you are not sure whether you have accidentally reversed channels, use a classical recording to check the location of the violins and double basses- the violins should be to the left, the double basses to the right.

Due to its minute output ( Millivolts as opposed to the .5 or 2 Volts of a tapedeck or CD player ), a turntable is NOT a standard line level input and needs its signal preamplified and equalized for RIAA before the TIGRIS can amplify it properly. Turntable preamps, also called phono stages, are available from a variety of manufacturers such as McCormack, Parasound, Creek and others. A turntable connected to such a phono stage may now be connected to any of the inputs of the TIGRIS. Do NOT connect a turntable DI- RECTLY to a line level input!

The Tape Output is a unity-level output and not controlled by the TIGRIS Volume control. Whatever incoming signal has been selected via the rotary input selector on the Front Panel, is fed through to the Tape Output. You could also consider a tape output a

Vacuum Tube Audio specifications

Mesa/Boogie is a revered name in the world of vacuum tube audio, renowned for its high-quality amplifiers that have shaped the sound of modern music. Founded in 1969 by Randy Smith in California, Mesa/Boogie began by transforming Fender amplifiers into customized, high-gain models, ultimately gaining a reputation for producing powerful, versatile, and low-noise amplifiers. The signature sound of Mesa/Boogie is characterized by a complex harmonic richness, warmth, and clarity that resonates with guitarists and audiophiles alike.

One of the standout features of Mesa/Boogie amplifiers is their all-tube design. Utilizing vacuum tubes as the primary amplification source, these amps deliver a dynamic range and tonal complexity that solid-state amplifiers struggle to match. The quality of the tubes used, often hand-picked or specifically designed by Mesa, contributes to the unique audio characteristics of each model. The use of EL34, 6L6, and 12AX7 tubes in various configurations allows for a range of tonal options, from lush cleans to searing leads.

Mesa/Boogie amplifiers are also distinguished by their innovative technologies. The brand pioneered the dual rectifier system, which allows players to switch between tube and solid-state rectification. This feature gives musicians the ability to tailor their sound to preference, enhancing the responsiveness and feel of the amplifier. The Contour controls found on many models further exemplify Mesa’s commitment to versatility, allowing for fine-tuning of EQ settings that adapt to different musical styles.

Another hallmark of Mesa/Boogie designs is their attention to build quality. Each amplifier is crafted with robust materials, ensuring durability and reliability even in demanding performance environments. The custom cabinets and speaker selections are optimized to complement the amplified tone, providing a cohesive sound that resonates in live settings.

Mesa/Boogie’s reputation is enhanced by their extensive lineup, including the Mark series, the Rectifier series, and the Lone Star series. Each line caters to different playing preferences and styles, from jazz to metal. The versatility of these amplifiers makes them suitable for diverse genres, allowing musicians to explore their sonic identities.

In conclusion, Mesa/Boogie remains a leading force in vacuum tube audio, combining traditional craftsmanship with cutting-edge technology. Their dedication to quality, innovation, and tonal versatility ensures that they remain a favorite among guitarists seeking the ultimate sound experience. Whether in the studio or on stage, Mesa/Boogie amplifiers continue to inspire musicians to push the boundaries of creativity.
