G.A.S Twin EC Stereo Adaptor

G.A.S Twin EC Stereo Adaptor — Dual-Signal Splitter

A two-way adaptor that allows a single G.A.S advanced controller to send separate signals to your intake and outtake fans — enabling proper fan balancing from one controller rather than needing two separate controllers. Plug and play compatible with all G.A.S EC controllers.

Why growers use the Twin EC Stereo Adaptor:

• Splits one controller output into two independent signals — intake and extract controlled separately from a single unit
• Enables proper fan balancing — set different max speeds on intake vs extract for tent pressure control
• Plug-and-play compatibility — no wiring, no configuration, just plug in and use
• Compatible with all G.A.S EC controllers — universal across the G.A.S advanced range
• Saves money vs buying two controllers — one advanced controller + adaptor = dual-fan management
• Essential for environmental setups — lets a single climate controller manage both fans intelligently

Who it's not for:

Only works with G.A.S EC controllers and EC fans. If you want full independent twin-fan control without sharing controller logic, use two separate controllers or the dedicated G.A.S EC Speed Controller instead. Pack reference 21.
