INTRODUCTION
The ART SMS226 is a two input, six output speaker management system with a number of advanced
functions and easy setup. The unit combines mono or stereo processing, a flexible crossover with speaker
protection and an automated setup facility. A graphic LCD display and LED meters allow control and
monitoring of the SMS226.
The speaker processor architecture is comprised of mono/stereo linkable processing modules on the two
inputs and mono processing blocks that apply to each output. Possible configurations are 2x2, 2x2 +sub, 2x3,
1x4, 1x5 and 1x6.
Input processing blocks include 1/3 octave graphic EQ, RMS compressor, noise gate, phase, feedback
suppression and sub-harmonic generator.
Output processing blocks include crossover filters, delay, parametric EQ, Limiter, level and phase control.
The Graphic EQ can be set up by an Auto-EQ function utilizing the measurement mic that comes with the unit.
The output processing blocks can be set up by the auto-configuration function, where the user selects
components from various manufacturers. Output Limiters can be linked in pairs for keeping stereo balance or
all tied together to additionally maintain the spectral balance.
The unit is controlled by a front panel interface that includes a graphic LCD, an array of mute switches located
under the LED meters for each input and output, an encoder knob and an array of switches.
The switch array allows the user access to all of the processing blocks directly. The encoder selects between
parameters and values through an integral switch. The LCD display shows parameter name and value
information plus a graphical representation of the value change.
Over 200 speakers and amplifiers are recallable from the setup wizard. Multiple custom speakers or entire
setups can be stored and recalled. When the system setup is complete, you can run an Auto-EQ function to
tweak the system using an external mic.
A PC-supported USB interface allows even quicker access to all of the functions of the device as well as
providing a backup storage mechanism. Factory presets can be updated through this interface insuring that
you have the latest fine tuned speaker crossover and amplifier data.
