Questions buyers ask

Before you request a quote

Can you design the sound system for my hall?
Yes — send the room size and use (conference, PA, worship, events) and we specify speakers, amplifiers and microphones to suit.
How long does installation take?
Most indoor walls up to 10 m² are installed and calibrated in one to two days; outdoor boards depend on the structure and permits. We survey the site first and confirm the schedule in the quote.
What warranty do you give?
Official manufacturer warranty on panels and controllers, serviced by our own engineers in Kathmandu with spares in stock. Warranty terms are itemised in every quote.
Do you deliver and install outside Kathmandu?
Yes. We have installed in Pokhara, Butwal, Bhairahawa, Dang, Dhangadhi, Lumbini and across the valley. Delivery and travel are itemised in the quote.
