Audioflow 3S-2Z Smart Speaker Switch

The Audioflow 3S-2Z 2-Way Smart Speaker Switch is a Wi-Fi-enabled solution for connecting two speaker pairs to a single stereo amplifier, perfect for managing zones like indoor and outdoor setups. If you’re familiar with speaker switches, this one steps up the game with smart control via the Audioflow app, Amazon Alexa, or integration into systems like Control4, ELAN, and RTI—eliminating the clunkiness of traditional selectors while keeping your amp count at one.

Compatibility and Impedance Handling

Designed for most stereo amplifiers, the 3S-2Z uses a series configuration to handle a broad range of speaker impedances. When both zones are on, the amp sees the sum of the impedances (e.g., two 8Ω speakers = 16Ω), so double-check your amp’s rating for safe operation. This flexibility suits setups with mixed speaker types without risking overload.

Connectivity and Integration

This isn’t your old-school switch. Wi-Fi connectivity ties it to the Audioflow app (iOS/Android) for remote zone control, while Amazon Alexa adds voice commands. It integrates natively with smart home platforms—Control4, ELAN, RTI, Crestron Home—via provided drivers. Prefer hardwired control? It’s got contact closure inputs for manual switches or automation tie-ins.

Wi-Fi Control: Toggle zones from your phone, anywhere on your network.
Voice Control: Tell Alexa to switch zones hands-free.
Smart Home Ready: Plug-and-play with pro-grade systems.
Wired Option: Hook up physical switches for direct access.

Setup and Control

Hook it to your amp, join your Wi-Fi, and configure zones in the app—it’s that simple. The interface is clean: tap to flip zones on or off. For anyone upgrading from a manual switch, this is a night-and-day improvement in usability.

Quick Install: Wired and running in minutes.
App Simplicity: No fumbling—just tap to control.
Remote Access: Manage it from your couch or across the house.

Control Options

You’ve got choices:

App: iOS/Android, intuitive and fast.
Voice: Alexa integration for hands-free ease.
Smart Systems: Native support for Control4, ELAN, RTI, etc.
Manual: Wire up switches via contact closure.

Audio Performance and Protection

Rated for 300W at 8Ω, it delivers clean power across zones. The series wiring keeps impedance manageable, and a 200Ω dummy load kicks in when all zones are off, shielding your amp from open-circuit damage—a must for peace of mind.

Power Capacity: Up to 300W at 8Ω.
Impedance Flexibility: Series setup adapts to your speakers.
Amp Safety: Dummy load protects when idle.

Standout Features

What sets it apart:

Wi-Fi/App Control: Ditch the manual switch for smartphone precision.
One-at-a-Time Mode: Lock it to single-zone output via the app—great for tricky impedance setups.
Expandability: Stack multiple 3S-2Z units on your network for bigger systems, all app-controlled.

Design

Made in the UK, it’s compact and light, slotting into AV racks or tight spaces with ease. The build is solid—reliable for years of use.

Small Footprint: Fits anywhere.
Lightweight: Easy to mount or move.
UK Quality: Durable and well-crafted.

Why You’d Want It

If you’re wrangling multiple zones, this switch saves you from extra amps while adding smart control. Flip zones via phone or voice, tie it into your smart home, and scale it up later—all without breaking the bank. It’s the modern fix for multi-room audio hassles.

FAQ

What impedances work?
Series wiring sums the zones (e.g., 8Ω + 8Ω = 16Ω when both active). Match it to your amp’s spec.
Wi-Fi optional?
Yep—use contact closure for manual control without a network.
Smart home compatibility?
Full drivers for Control4, ELAN, RTI, Crestron Home.
Multiple units?
Absolutely—add more switches, control them all from the app.
Zone disabling?
Tap off in the app or set one-at-a-time mode for single-zone focus.
