World-Class Pro Audio & Stage Technology
Authorized tier-1 supply and integration partners for the world's most rider-friendly acoustic and stage hardware.
The 5 Pillars of High-Impact Auditorium AV
Bad acoustics and weak sound distribution ruin even the most expensive visual setup. Our end-to-end engineering guarantees pristine speech intelligibility and concert-grade musical fidelity.
1. EASE 3D Acoustic Simulation & RT60 Tuning
Before buying a single speaker, our acoustic consultants create a 3D ray-tracing simulation of your venue in EASE software. We analyze surface reflections, flutter echoes, and room resonance to engineer custom acoustic wall paneling, ceiling baffles, and rear-wall diffusers targeting an optimal RT60 between 0.9s to 1.2s.
- Speech Transmission Index (STI) targeted at > 0.68 (Excellent)
- Fire-retardant (Class A / Class 1) fabric acoustic paneling
- Bass trap corners eliminating low-frequency boominess
2. Line Array Sound Reinforcement & Front Fills
Curvilinear flying line arrays (JBL VTX A-Series / CBT column arrays) project sound uniformly across deep auditorium seating. Front-row fill speakers ensure front audience members hear natural sound originating directly from the stage rather than over their heads.
- Uniform SPL across all rows (98 dB to 105 dB headroom)
- Under-balcony delayed fills for covered seating tiers
- Stage subwoofers with cardioid steering preventing stage rumble
3. Dante & AES67 Digital Network Audio Backbone
Say goodbye to bulky analog snake cables. We deploy an uncompressed, zero-latency Dante / AES67 digital audio network running over redundant Cat6A/fiber lines. Microphones, stage boxes, DSP processors, and amplifiers communicate digitally with zero ground hum.
- BSS Soundweb London / Symetrix DSP automated feedback elimination
- Digital stage boxes with remote gain preamps from sound booth
- Multi-track recording output for professional archive audio
4. Stage Active LED Backdrop & Laser Projection
High-brightness Fine-Pitch Active LED walls (P1.8 to P2.5) that stay vibrant under bright stage spotlights. Supports multi-window PowerPoint presentations, convocation name scrolls, keynote video feeds, and immersive stage backdrops.
- 3840Hz high refresh rate for flicker-free camera recording
- Confidence monitors on stage floor so speakers never turn back
- Seamless presentation switching between laptops with zero black freeze
5. Motorized Stage Rigging & DMX512 Lighting
Motorized electric hoists and aluminum box trusses that allow safe ground-level maintenance of stage lights and banners. Complete DMX512 intelligent lighting system with warm white profile spots, moving heads, and LED wash lights.
- Programmable lighting presets (Conference, Drama, Musical, Off)
- Motorized main curtains and side tormentor acoustic drapes
- Certified load-rated rigging hardware compliant with safety norms
6. 4K Auto-Tracking PTZ Broadcast & Streaming
Broadcast-grade robotic PTZ cameras (Sony / Panasonic / Lumens) with AI-powered speaker tracking. Automatically follows the speaker as they walk across the stage, streaming 4K video to YouTube Live, Zoom, or campus overflow rooms.
- Multi-camera video switcher with instant graphic title overlays
- NDI / SDI low-latency distribution across campus networks
- Simultaneous clean audio-video master archive recording

Auditorium Engineering FAQ
Why is RT60 acoustic treatment critical for auditoriums?
RT60 measures reverberation time—how long sound takes to decay by 60 dB. For speech clarity in auditoriums, an optimal RT60 between 0.9 and 1.3 seconds is required. Without acoustic fabric panels, bass traps, and diffusers, sound echoes excessively, rendering speech unintelligible.
Why are line array speakers preferred over standard point-source speakers?
Line array speakers project sound as a cylindrical wavefront that attenuates at only 3 dB per doubling of distance (compared to 6 dB for point-source). This guarantees uniform sound pressure levels (SPL ±2 dB) from the front VIP row to the very last balcony seat.
How do you avoid wireless microphone dropouts in high-interference areas?
We deploy digital wireless systems (Shure Axient Digital / ULX-D / Sennheiser EW-DX) with remote active directional antennas, antenna distribution amplifiers, and automated frequency coordinators that switch channels instantly upon detecting 5G or RF interference.
What display options work best as an auditorium stage backdrop?
For contemporary stages, Fine-Pitch Active LED Video Walls (P1.8 to P2.5) are preferred because they deliver 800+ nits brightness, allowing stage spotlights without washing out presentations. For ultra-wide panoramic backdrops, high-lumen 3-chip DLP laser projectors (20,000+ ANSI lumens) with motorized tensioned screens are also deployed.
Can an auditorium be operated by non-technical staff?
Yes. While a sound engineer console (Yamaha/Soundcraft) is available in the control booth for complex live shows, we program custom Crestron or AMX touch panels with pre-configured scenarios (e.g., 'Keynote Presentation', 'Panel Discussion', 'Cultural Play') that adjust audio, lights, and displays automatically with a single button press.
Are your auditorium installations compliant with GeM and CPWD standards?
Yes, GPSPL complies with CPWD electrical and acoustic specifications, fire-retardant fabric classifications (Class 1 / Class A), and provides complete OEM Manufacturer Authorization (MAF) and BIS certificates for Government e-Marketplace (GeM) tenders.
