Midas - A Brief History

Since 1969 Midas has been the premier console brand throughout the world of professional audio. Midas consoles have been on the road with acts like Pink Floyd, Paul McCartney, Rolling Stones, Madonna, U2, Coldplay and Kylie just to name a few. From the famous Pro Series, the benchmark XL3 and XL4, and onto the current industry standard Heritage 3000, Midas remains the first choice for the most discerning of professional live sound engineers and has set the standard in the industry. The Midas sound is a commonly heard phrase in the world of pro audio and refers to the sonic performance of Midas consoles the mark by which others are judged. It comes simply from a unique combination of a superb dynamic range, very low noise floor, flawless audio path transparency and a beautifully warm EQ and the industries finest microphone pre-amp - plus thirty years of experience from a design team that not only understands audio but also loves music. Sonic performance is only part of the reason behind Midas success; there is also the outstanding product reliability. Midas consoles are able to handle thousands of gruelling events and hundreds of thousands of miles of punishing touring without major fault. To back up our impeccably solid construction and proven roadworthiness there is a three year global warranty, so our support network of dealers and distributors are on call at all times should any of our products need any kind of after-sales service. Midas proven technology and track record has made it an essential tool in numerous applications. Countless theatres, broadcasting suites, Houses of Worship, conference specialists and installation
companies entrust their live sound requirements to Midas. The reason for this confidence is simple. It is founded on the fundamental philosophy behind Midas: totally uncompromising research, design, engineering and manufacturing which results in a product synonymous with excellence.

Siena - Introduction

Siena brings all of Midas knowledge and experience in building dual-purpose consoles, such as the industry-leading Heritage 3000 and the now-legendary XL3, and offers all of these benefits in a compact package. Siena has been designed to both compliment and expand the ground-breaking Verona concept. Built on the highly successful, proven Verona platform, the Siena represents a combination of superb audio performance, and increased functionality, creating a new, class-leading, dual-purpose console. Siena is more than a Verona with extra auxes. The buss structure has been redesigned to be more appropriate for monitor use. Sophisticated engineering solutions have been employed, such as the advanced Solo Tracking System, switched inserts on outputs, and a powerful logic controlled solo system. Siena has a comprehensive control surface, however, it still maintains the familiar ergonomic layout of all Midas consoles, making navigation around the control surface quick, easy and intuitive. Siena will appeal to the discerning audio professional, be they working in Concert sound, Theatre, Broadcast, House-of-worship or Audio-Visual, and at either end of the multicore.

Siena Overview

Unique Module Construction

Semi modular construction in 8 channel blocks based on the proven Verona platform. Modules blocks feature a structural sub chassis carrying 2 PCBs and a separate (non structural) dress facia. This construction eliminates the need for long ribbon cables or expensive back planes and improves both reliability and crosstalk without sacrificing serviceability. The sub chassis provides electrical screening under the PCBs protecting busses from noise pickup and allowing the use of internal power supplies without interference. PCBs are produced with all surface mount components on the underside so that they are not affected by the build up of debris after years of use. Electrolytic capacitors are mounted conventionally on the top of the board, which provides them with a high degree of thermal protection increasing reliability and lifetime. The non-structural front panel can be easily removed allowing direct access to the PCBs for service. All major circuit nodes are marked as test points on the top of the board to simplify fault diagnosis at system level or down to component level in situ.

Input Module

Switched insert points on every channel. 4 LED input metering on every channel. Highly accurate and musical swept 4 band EQ on every mono channel. Soft mute circuit with silent operation and led indication. 16 Mix busses with individual Pre/Post Fader switches. Pre fade Mix EQ bypass switch. 100mm monorail faders.

Input Connectors

The main XLR input is for use with balanced Mic or Line level signals. The line jack is for use with balanced or unbalanced line level signals and is protected from 48V phantom.

Midas has been designing and manufacturing live performance mixing consoles for the worlds most demanding sound engineers, performers and production rental companies since the early 1970s. The evolution of Midas consoles throughout the 30-year history of this classic marque has always paralleled, and often led, increasingly sophisticated audio innovations for the world-wide entertainment technology industry. Raising the standards of sonic quality through continual research and development has always been - and still remains - our overall aim. Equally important to us is the design and implementation of many new areas of control functionality and user-friendly desk operation to anticipate and accommodate the rapidly changing and expanding needs of audio professionals who specify Midas consoles for their major tours, festivals, international events, broadcast projects and prestigious fixed installations. The Midas design pedigree has, since our birth, been founded upon a track record of achieving a unique symbiosis with working sound engineers around the planet - engineers who respect and endorse our proven technology in the light of their responsibilities to their internationally-based clients who are themselves the leading lights of our industry.
