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
• Sound masking system must be able to provide music muting capabilities to allow paging to smoothly override masking
• Spatial uniformity of sound must be no more than ±½ dBA
• Sound masking, paging and music must have individual identifiers located in an integrated LCD screen
• Plenum mounted network locations must have a lighted LED for visual inspection.
• System must be a multi-drop network system. Point to point systems are unacceptable
• System must be capable of being tuned through a network and a hand-held remote
• The system must be capable of being independently zoned on both a global and local level for sound masking, paging and music. All zoning must be controlled from a network appliance
• Generation and integration of multiple random sound masking sources and by using E-sound® technology equates to the best sound and effective sound masking
• System must be capable of performing a complete diagnostics of its entire functions including diagnostics of the network, hubs, nodes, routers, dsps, memory, circuitry, amplifiers and power
• 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
