Rosette Acoustic DI Preamplifier


Overview:
Capture Your Acoustic’s Tone with Detail and Clarity Like Never Before.

Introducing the new Rosette™ Acoustic DI Preamplifier for home, studio or stage.

When we turned our eyes and ears toward amplifying acoustic sounds, one thing more than any other stood out as an objective; Do No Harm. In its sincerity and perfection, there is no reason to “enhance” the sound of the acoustic guitar, or any other acoustic instrument for that matter, but rather… just reproduce it.

Introducing the Rosette™ DI, an Acoustic Instrument Direct Interface that puts accurate reproduction at the top of the list, and yet, also offers comprehensive shaping power for enhancement when you might need it.

We start with the same Front End and EQ circuitry used in our Rosette™ 300 Two:Eight Combo, minus the Mic Input. Both products’ circuit design is derived from high end recording console design. This no-compromise approach ensures the purest signal path and lowest noise specs while at the same time insuring detailed, rich musicality and unrivaled accuracy.

As you would expect on any pro console, both Input Gain and Phase are addressed in the INPUT control and PHASE switch. A wide range of high impedance pickups are handled easily with the optimized, current source-biased FET input stage. The Phase relation between pickup output and whatever speakers are being driven can be addressed by flipping the PHASE switch on the Rosette DI for easy comparison to decrease or eliminate feedback or even improve your overall tone.

From there we’ve included two additional sweep-able Filters to assist with feedback elimination in the live performance environment. NOTCH FILTER cuts a chosen frequency in a narrow band to remove resonant frequencies that cause feedback. This Filter removes those frequencies as it is rotated clockwise. The HI-PASS is also a Filter that cuts frequencies in the sub-harmonic range as it is turned clock-wise. This is very helpful in both eliminating unwanted low frequency feedback on stage as well as tightening up the low-end for specific instruments or musical styles.

A footswitchable BOOST is incorporated for increasing the level of certain musical sections like solos or anyplace a level increase is needed. The BOOST LEVEL sets the amount of BOOST when the BOOST switch is engaged. Additionally a footswitchable MUTE is also included which mutes the signal at the Rear Panel outputs but does not mute the side TUNER Output, enabling you to employ silent tuning between songs.

The fully professional EQ Section incorporates fixed shelving BASS and TREBLE controls plus two semi-parametric MID bands covering LOW and HIGH midrange frequencies. These can overlap for finite control over adjacent midrange frequencies or one might be used to combat feedback while the other is applied for Tone shaping duties.

Experience the new Rosette DI Preamp. The result of 48 years of definitive amp design and a focus to deliver the most accurate reproduction of your instrument’s acoustic sound possible in amplification.

Rosette 300


The Home of Tone®
Few can deny the intrinsic beauty of Acoustic Instruments. The visual beauty of the Tonewoods, curvaceous shapes with elegant lines and delicate artwork of inlay all in harmonious interplay with a pure sound unique to stringed instruments. It is this purity in sound that we set out to capture in the Rosette™ Acoustic Amplification Series.


Overview
Capture Your Acoustic’s Tone with Detail and Clarity Like Never Before.

Introducing the new Rosette™ 300 / Two:Eight Acoustic Combo Amplifier with 300 Watts of portable power, 2 Channels and a professional grade feature set for home, studio or stage.

The new MESA/Boogie® Rosette™ 300 / Two:Eight Acoustic Amplifier shown in standard finish British Tan Bronco with Cream & Tan Weave Grille and new Dark Brown Leather Corners and Dark Brown Handle

Few can deny the intrinsic beauty of the Acoustic Instrument, especially the Acoustic Guitar. The visual beauty of the Tonewoods, the curvaceous shapes and elegant lines of body styles, and the delicate artwork of inlay all coalesce in harmonious interplay with tensioned strings to produce musical promise.

So when we at MESA® turned our eyes and ears toward amplifying these sounds, one thing more than any other stood out as an objective; Do No Harm. In its sincerity and perfection, there is no reason to “enhance” the sound of the acoustic guitar, or any other acoustic instrument for that matter, but rather… just reproduce it.

Unlike electric guitar amplifiers that offer myriad enhancements and often complete re-voicings, the acoustic instrument has all the complex harmonic content it could ever need, on-board. All that is required is the accurate reproduction of that beauty.

While staying true to the concept of Do No Harm, few products or companies seem to share this perspective for Acoustic Amplification. And when it comes to the electronic and mechanical components and design needed to fulfill that order, it’s easier said than done. It requires a commitment to using the absolute best components and circuit design dedicated to uncompromising accuracy, purity of sound and the lowest possible extraneous noise.

The ROSETTE line is a dedicated acoustic instrument platform designed not just for acoustic guitars, but also for mandolin, ukulele, violin/fiddle, dulcimer, cello, upright bass and other uniquely acoustic instruments.

Our reverence and appreciation for acoustic instruments guides the designs of the Rosette Series products. Our commitment to produce innovative, reliable and inspiring musical instrument amplification for nearly 50 years, finally includes the incredible world of acoustic instruments. Introducing the Rosette 2x8 combo and the Rosette DI Preamp/Pedal.
