SIAP Mark V – Electronic Architecture of the 21st century

A comprehensive concept but user friendly

SIAP Mark V is built with a vision that technology needs to be flexible and has the potential to expand and improve anytime and anywhere. The design is elegant, simple. You only see what you need to see, it does what it should. It talks Dante and easily integrates with Dolby Atmos. With instant preset switching you can build unique performances. The iPad executes your wish with the beautiful control app. The power consumption is low, which makes our technology green and energy efficient.

Matrix Flexibility

Route what you want

With all independent channels you can route every input to every output, simultaneously with the acoustic preset active (processed and unprocessed).  Let’s have a piano concert, combined with anouncements and some vocal soloist. 1.) An acoustic preset (e.g. RT = 1.6), 2.) Unprocessed input for announcer and 3.) Processed input for vocal soloist. Enhance the vocal soloist with PA to get a strong (correct) frontal localisation, add the reverberation (wet/dry) to the hall as much as you like.

  • up to 384 independent channels (if stacked, 768 channels)
  • each channel can generate a dedicated reverberation pattern by FIR filters (128 in total)
  • early and late (diffuse) reflections can be used and modified independent
  • for each reflection pattern the following characteristics can be modified independently:
    – length of early and diffuse reflection time (up to 6,5seconds)
    – level of the reflections
    – density of the reflections (up to 20000 per second per signal path = 2,560,000
  • reflections per second @ 48 kHz sample rate; up to 10,200,000
  • reflections per second at 192 kHz sample rate)
  • frequency characteristics in octave bands from 31.5 to 16,000 Hz
  • double or multiple sloped decays can be generated
  • independent dedicated acoustic zones for under balcony or stage areas with own reverberation times, envelopment and frequency depended RT
  • Instant preset switching (no loading times)
  • no compression
  • equalization of multiple filters on inputs and outputs, separately
  • the system does not use any time variant techniques in order to obtain sufficient gain before feedback, so it is fully time constant
  • only a limited number of microphones necessary to pick up the direct sound on stage
  • possibility for extension microphones for congregational enhancement and/or specific situations where more coverage is needed in the hall for picking up the sources on all desired areas
  • additional line inputs/outputs for theatre sound effects, enhancement of (weak) soloists, monitoring showrelay to (dressing) rooms, recordings purposes, filmsurround etc.
  • low noise fan cooled processor, so it can be installed in the sound control room (LAeq< 30dB(A)) without disturbing the work of engineers
  • communication based on TCP/IP, therefore easy to integrate with platforms like AMX or crestron, supports Dante & MADI I/O communication and ready to support other audio protocols
  • multiple control terminals to be connected to one processor
  • can be used as an acoustic server, i.e. one processor for multiple rooms (simultaneously)
  • infinite amount of presets to be stored
  • easy to use control software (one push on a button)
  • all presets stored as factory presets and user presets
  • live monitoring of all outputs and inputs of the processor available
  • the loudspeaker layout is based on acoustic principles
  • Clipping protection system
  • AFRS, optional (SIAP Active Failover Redundancy System, switches automatically to another processor in case of failure)
  • dedicated design concepts for e.g. under balcony areas and / or stage areas
  • scalable by modular design
  • future proof (easy software & firmware upgrades)
  • optimization for small, medium and large roomss: proven results

Taking your moment to listen to the sound check and/or rehearsal before showtime. Sitting on your chair and instantly switching to different presets to select the proper acoustics that does exactly the right justice to the type of performance. 

Listen! You will love it.
