Midas Siena 400:

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 will appeal to the discerning audio professional, be they working in Concert sound, theatre, Broadcast, House of Worship or Audio Visual industry and at either end of the multicore.

Models:Siena 240 / 320 / 400 / 480 / 560

Three Functions, One Desk: Easy to set-up for monitors: the Mono/Stereo changeover switches, allows the choice of any combination of wedge or stereo in-ear monitor outputs to be controlled via a 100mm fader including switched insert point. This flexibility also extends to FOH operation as mixes 9-16 will act as sub-groups as they can be routed to stereo master outputs and include pan and stereo assign switches. Routing inputs to groups is easily achieved by dialling the appropriate auxiliary to unity gain.

Superior Midas Sound: Siena uses a premium performance mic amp design, with very high CMR performance providing simple, noise free interconnections. High performance audio summing busses are used throughout and all main outputs are fully balanced with high current capability for noise free interconnections.

Equaliser: Highly accurate and musical swept 4-band EQ on every mono channel. The stereo channel is the same variety with swept mids. There is a switched high pass filter on every channel plus swept frequency on mono inputs.

16 Mix Outputs: 16 mix busses with individual Pre/Post Fader switches in mono mode. 8 global master Mono/Stereo switches, which reconfigure the mix busses in pairs to a Pan/Level arrangement with stereo Pre/Post switching. The 16 master mix outputs also include 16 100mm faders and 16 separate meters.

5 Mute Groups: Easy to set up, easy to activate mute scenes. The soft mute circuits have silent operation and LED indication. Mute group 5 also operates on assigned groups.

4 Mute Groups: Easy to programme, easy to re-call mutes created from inputs. The soft mute circuit has silent operation and LED indication

Channel Inserts: Front panel switchable insert points on each mic input.

Unique Module Construction: Semi modular construction in 8 channel blocks. Modules blocks feature a structural sub chassis carrying 2 PCBs and a separate (non structural) dress facia.

Faders: 100mm monorail self cleaning faders

PSU's: The current sharing, voltage sensing, auto-switching PSUs are internally mounted. The "no hum" design saves the need for external racking and cabling. Siena 240 comes with one internal PSU whilst Siena 320, 400, 480 and 560 come with two internal PSUs. Each frame includes an external connection port for an optional external PSU.

Warranty: Midas has confidence in their products resulting in an industry beating 3-year warranty.

"When my fiancé told me he wanted an acoustic guitar for his birthday, I had no idea how I was going to pull it off. However, this site made it very easy for me. It is very easy to find what you are looking for and the "related items" helped me pick out some accessories. I did experience a problem when it came to shipping. One of my items was reported as delivered by UPS. But when I contacted ActiveMusician, they sent out another stand right away, and it still arrived in time! I have nothing but good things to say about this site, and I have already started telling everyone about them!"
