GET GST INPUT
Ever wondered why speakers, amplifiers, projectors etc. come with a slightly heftier price tag in India compared to their overseas counterparts? Well, part of the answer lies in our country's Goods & Services Tax (GST).
But here's the kicker: Don't let that GST input slip through your fingers! Especially when some of the products we supply carry a GST rate of 18% and 28%.
At AVStore, we provide you with a GST compliant invoice for every purchase.
Simply put in your GST number during the checkout to avail an offset.

Parasound 12-Zone Audio Power-Compact, Precise, and Ready
The ZM12 packs twelve channels of powerful amplification into a compact 2U rack unit-perfect for delivering music or voice across multiple rooms without taking up space. It combines robust power with flexibility, making it ideal for home or commercial multi-room sound systems.
The ZM12 powers 12 channels across 6 zones, with Zone 1 at 120 W/ch into 8 Ω (150 W into 4/2 Ω) and Zones 2-6 at 60/100 W. A Class‑AB input stage feeds premium Class‑D modules that are stable at 2 Ω, while A/B speaker outputs per channel (24 total) and stereo/mono per‑zone switching simplify real‑world wiring. Integration is painless with per‑zone audio‑sensing and 12 V triggers plus a speaker‑level input for systems without pre‑outs.
