NOTE

1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25 of ambient temperature.
2. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1uf & 47uf parallel capacitor.
3. Tolerance : includes set up tolerance, line regulation and load regulation.
4. The power supply is considered a component which will be installed into a final equipment. The final equipment must be re-confirmed that it still meets EMC directives.
5. Derating may be needed under low input voltages. Please check the derating curve for more details.



The Spectra i.Net® Sound Masking System must provide the following:

  • All masking/paging units must be UL Listed for air handling space
  • System must confirm following ANSI standards: ANSI S1.4, ANSI S1.6, and ANSI S1.11
  • System must meet ASTM 1130-02, ASTM E1573-02, ASTM E 1374-93, and ASTM E 1041-85 standards
  • The Sound Masking system must use a unique integrated sound masking, music and paging system that uses the power of network technology, web appliances, internet access, infrared remote controls and digital signal processors (DSPs)
  • The Sound Masking system must be capable of separately and independently configuring zones for sound masking, paging and music via the network empowered through its central control
  • The Sound Masking system must produce 20Hz through 20,000Hz from its source
  • The masking must be random and provide a minimum pattern of no LESS than 25 hours.
  • The sound masking devices must provide both a 1/3 octave band equalizer for a minimum of 30 bands and a parametric equalizer to adjust the sound masking
  • The paging devices must have a minimum of a 1/1 octave band equalizer to shape sound
  • The masking volume shall be adjustable via digital means for ½ dB steps for a range of 36-84 dBA as measured 1m from the center of the speaker

  • System must be capable of reporting entire settings for each zone for masking, paging and music indicating at a minimum the volume, contour, 1/3rd band octave equalization, parametric equalization, diagnostics, and groupings
  • System must be an open platform system. Proprietary software systems are UNACCEPTABLE.
  • System must be capable of using off the shelf browser software for full manipulation
  • System must be capable of being used as a stand-alone system or a system tied into an intranet IT spine or manipulated through the internet
  • Speaker housings/enclosures must be damped to avoid undesirable resonance
  • System shall be designed so that individual speaker or component failure will have no impact on the balance of the system
  • Security: Central control must only be able to be accessed via an authorized computer access point with the use of a password
  • Sound masking equipment must be comprised of at least 50% recycled content
  • A 10 year full warranty from the manufacturer must be provided for all sound masking equipment
  • The system must be manufactured in the USA
