The Midas Siena audio mixing console has been introduced to address the needs in the midrange sound reinforcement market. The output buss structure has been redesigned more appropriately for monitor use.
Midas Siena Analog Audio Console Features
Offering six different frame sizes from 24 to 64 inputs, the Siena presents true audio performance and value in an affordable package for dual-purpose (monitor and front of house) live sound applications.
The mixing console is a semimodular construction in eight channel blocks. Its modest dimensions on the 40 input version is 9 inches high x 31 inches deep x 62 inches wide, and at a weight of 143 pounds, is very manageable in setting up.
Each Siena includes as standard 16 mix buss sends, with global master mono/stereo switching in pairs. With one stereo master output, one stereo solo output and separate mono solo output, its solo cueing system is very intuitive for monitor engineers.
At the top of the mono input module are switches for phantom power (48VDC), 15 dB pad, phase, and insert enable. The gain control for the microphone preamp gives continuous adjustment from +15 dB to +60 dB. The Siena microphone preamplifier can handle input levels up to +21 dB. This assures improved RF rejection and low noise performances similar to the Heritage series.
The equalization section features a four-band sweepable EQ with a separate I/O switch; an adjacent switch sends desired signals pre EQ to the auxiliary sends. It provides a range on each band of ±15 dB and a fixed Q of one octave in each bandwidth. Every mono input channel has a variable high pass filter (20 Hz - 400 Hz) with I/O switch for removing handling noise and unwanted low end in the input signal.
The Siena input module has 16 mix sends. Each mix has a separate gain control knob to adjust level from OFF to +6 dB. All 16 mix sends are globally switched mono/stereo in pairs. Its flexibility permits running 16 mono mixes and a stereo mix, or nine discrete stereo mixes, or any combination of mono or stereo mixes desired.
Above the long throw 100mm fader is a four-segment LED meter (18 dB, 0 dB, +12 dB, +18 dB). Completing the mono input module is a mute and solo switch with LED indicator that illuminates to depict when active. The Siena has five auto-mute busses that can be controlled from the center section of the console. Any input channels can be assigned to auto-mute groups 1 - 5 as desired.
The center section of the console contains fader and muting control for all outputs. All output modules have graduated LED bar graphs with 16 segments that provide good monitoring of output signals. All outputs are balanced with XLR connections on the back of the console. Direct outputs on every channel can be used for multitrack recording, or sending to a dedicated effects processor. All direct outputs are post fader as standard but can be modified via internal jumper to provide prefader, pre-EQ/post-mute, pre-EQ/pre-insert or post-EQ if desired.
All Siena consoles (except the Siena 240) come with two internal power supplies. In addition, a multipin connector is provided for interfacing an external linear backup power supply, which is a well thought out design feature to ensure reliability on the road. The power supply units are current-sharing, voltage sensing and auto switching, providing proper assurances that might be necessary to save a show.
