What LDA Audio Tech does
LDA Audio Tech (legally LDA Audiotech S.L.) is a privately-held Spanish electronics manufacturer headquartered at Málaga Tech Park, where it conducts all in-house research, design, and manufacturing of EN 54-certified public address and voice alarm (PA/VA) systems. Founded approximately 48 years ago, the company was the first in Spain to obtain EN 54-16 certification and now exports to 60+ countries with more than 2,000 projects installed. Its portfolio spans two hardware tiers — the flagship NEO+ system with AES67 Level 3 digital audio-over-IP, redundant controllers, and capacity for 800+ person venues, and the compact ONE system (EN 54-16 and EN 54-4) for 200–799 person venues — complemented by EN 54-24 certified loudspeakers and accessories including the proprietary NEXO AES67 converter, MPS-8Z+ paging microphone, and TFL-2 end-of-line supervision device.
The software layer consists of four tiers: NEO Control (basic local management), EVAC Cloud (remote cloud-based supervision with fault alerts), EVAC Control (advanced local operation with AI-assisted multilingual text-to-speech), and SIME (enterprise-grade management for multi-site deployments with SIP VOIP and redundant server architecture). LDA generates revenue through three streams: hardware system sales (NEO+, ONE, loudspeakers, accessories) sold via project-based quotes; software licensing and subscriptions including cloud-hosted platforms; and professional services through the LDA Academy training program. The go-to-market combines direct enterprise field sales for large infrastructure projects with an exclusive distributor network (Rondo-Sound for the EAEU, Gräf & Meyer for Central Europe) and regional offices in Spain, Saudi Arabia, Qatar, Egypt, and India.
Customers span airports, shopping centers, rail/metro networks, stadiums, hospitals, corporate towers, logistics centers, tunnels, and educational institutions. Integration with third-party security platforms (Genetec Security Center via a San2 plugin, Vigiplus/DESICO via MODBUS, and the Atalaia Alliance co-developed with Detnov and ALCAD Facility) is enabled through open protocols (AES67, IP, RS-485, dry contacts). The company reinvests 10% of annual turnover in R&D, holds EN 54-16/24/4 plus Australian AS 4428 and Middle East Civil Defence certifications, and added ISO 27001, 45001, and 14001 in January 2026.

LDA Audio Tech competitors and assessment
Company assessmentBroad incumbents
- Bosch Security Systems: Bosch's Praesideo and PAVIRO product lines are direct EN 54-16 certified PA/VA competitors to LDA's NEO+ and ONE. As a broad incumbent, Bosch bundles voice evacuation with fire detection, access control, and video into integrated enterprise security stacks, applying significant pricing pressure on mid-sized specialists.
- Honeywell: Honeywell's NOTIFIER and Xtralis (ASEN) lines cover voice alarm, fire detection, and integrated building systems. Comparable to LDA as a global supplier competing for the same airport, hospital, and commercial real estate projects, but with substantially larger scale and broader portfolio.
- Siemens: Siemens Cerberus PACE and Sinteso platforms include EN 54-certified voice evacuation as part of integrated fire safety and BMS offerings. Competes head-to-head with LDA on large infrastructure tenders such as airports, metros, and hospitals across Europe and the Middle East.
- Eaton (Wheelock / Cooper Notification): Eaton's Wheelock and Cooper Notification lines are direct competitors in EN 54 / NFPA voice evacuation systems. Competes with LDA in commercial, transportation, and industrial venues globally, leveraging larger fire-alarm channel reach and bundled life-safety packages.
Direct peers
- TOA Corporation: TOA's VX-3000 and SX-2000 series are EN 54-16 certified IP-based PA/VA systems directly comparable to LDA's NEO+. Targets the same airport, stadium, and large-facility use cases with a similar two-tier hardware and software architecture.
- Zenitel: Zenitel (formerly Phonak Communications) supplies EN 54-16 voice alarm and public address systems with strong presence in tunnels, rail, and marine markets. Closely comparable to LDA's AES67-based NEO+ and to its tunnel and rail customer segment focus.
- ATEIS: ATEIS manufactures IDA8 and PAV8 EN 54-certified PA/VA systems with Dante/AES67 networking. Direct competitor to LDA in the European voice evacuation market, sharing similar target verticals and enterprise project-based go-to-market.
- AtlasIED: AtlasIED (Atlassound / IED) supplies IP-based and EN 54-16 certified mass notification and voice evacuation systems. Closely comparable to LDA in stadiums, transportation hubs, and large commercial venues with a focus on integrated security platforms.
- Biamp Systems: Biamp's Tesira and Vocia lines provide networked EN 54-16 voice evacuation and pro audio solutions comparable to LDA's NEO+. Similar enterprise project motion across airports, universities, and corporate campuses, though Biamp's larger installed base in the US differs from LDA's European strength.
Emerging players
- Riedel Communications: Riedel offers Bolero wireless intercom and PA systems with growing presence in live events, broadcast, and venue communications. Partial overlap with LDA in large venue/stadium communications, but with a stronger focus on intercom and broadcast workflows rather than regulated evacuation.
