NIGP 28706: Amplifiers and Preamplifiers (Not for Sound Systems or TV Antennas)

NIGP 28706 Amplifiers and Preamplifiers (Not for Sound Systems or TV Antennas), an Item code, covers specialized electronic amplification equipment that state and local governments procure for mission-critical applications including public safety mobile data systems, water utility operational controls, stadium audio infrastructure, and research facilities. Recent solicitations show governments buying replacement amplifier modules and integrated amplification components as part of broader system upgrades or replacement cycles—notably Sierra Wireless mobile data terminal upgrades with onboard amplification for fire rescue fleets, AC drive modules with embedded amplification for water filtration plant automation, lock-in amplifiers for university research, and stadium-scale sound reinforcement system amplifiers. Issuing bodies span county governments (Hillsborough County Fire Rescue, Riverside County Water), city procurement offices (City of Orlando), universities (Texas A&M University System), and cooperative purchasing vehicles serving multi-jurisdictional needs (Sourcewell representing participating counties across Washington state and beyond).

Recent activity concentrates in Florida and California, with outlier opportunities in Texas and Minnesota-coordinated regional purchasing. Representative recent solicitations include the City of Orlando's RFP 260476 (posted June 30, 2026; due July 31, 2026) for main bowl sound system amplification as part of a turn-key Camping World Stadium upgrade, Hillsborough County Fire Rescue's ITB 26-00212 (posted March 25, 2026; due April 15, 2026) for SemTech/Sierra Wireless Mobile Data Terminals including embedded amplification across 225 fire rescue vehicles over five years at $987,240, and Riverside County's RFB 3918 (posted March 3, 2026; due March 25, 2026) for an ABB ACS880-04 AC Drive Module replacement at Perris Water Filtration Plant. Sourcewell's RFP 061626 for Law Enforcement Equipment (posted May 12, 2026; due June 16, 2026) establishes a cooperative contracting solution available to multiple jurisdictions across Washington and participating entities nationwide, though the full scope of amplifier-specific equipment is not detailed in available documentation.
