[ Field reports ]

Judged on the load-out, not the spec sheet.

Every unit is bought by someone who has to carry it, rig it and answer for it at 2 AM. This is what they came back and said.

Using 2 pcs MX-1600 since last Diwali. Around 40 functions till now, mostly outdoor. Heat sink gets warm but no cut-off till now. Packing was proper, double box.

Good product. Customer only asks for this now.

AJ6 is doing the job for small setups. Gain is clean, no hiss at half volume. Only issue is the aux send is single, so monitor and effects both cannot go together. Manage kar liya but keep in mind before buying.

Third monsoon on the same cabinets. Corners are still tight, no rattle. I load in and out 3 times a week so this matters more than sound quality honestly.

Ordered 14 nos for a college auditorium. All 14 came tested, output matched within a hair. Delivery took 9 days to Kochi which is slightly long, but not a single RMA. Will order again for the next site.

Mic is good for the price, no doubt. Handles a loud singer without distorting. The mic clip that comes with it is cheap plastic, mine cracked in a month. Bought a separate clip, otherwise no complaint.

Asked for dealer rate on WhatsApp, got the rate card same day. The person actually knew what I was asking about. Rare.

Fitted D518 on my existing tops. Crossover sorted the overlap in one go, did not need to tune much. Highs are clear at high volume, not paining the ears after 3-4 hours.

Rohit KalraClub DJ · Delhi

Took 1 amp first to check quality. Took 5 more next month. One fader became loose after 2 months, they replaced it, no argument. Sunday ko bhi reply kiya. Only thing, courier packing could be better.

[ 02 — Origin ]

From a workshop in Chandni Chowk, we move air across India.

Desire Electronics has traded in audio since 2004. PRO1st is the professional line: imported drivers, transformers and DSP boards mated to housings, chassis and crossovers built on our own floor at Moti Cinema Compound.

That split is deliberate. We buy the components nobody should improvise, and we build the parts that decide whether a cabinet survives a monsoon load-in. Every unit is bench-tested before it leaves the compound.

Installers and AV contractors: send us the room and the headcount. We will return a chain that interlocks, from mic to cabinet, with load figures.
