1. Understanding the Basics of Wireless Audio

How Wireless Audio Works

Wireless audio systems use radio frequencies (RF) or infrared (IR) to transmit sound from a source (your phone, TV, or PC) to a receiver that feeds the signal into the speaker’s terminals. The most common standards are:

• Bluetooth: Short‑range (up to 30 ft), low‑latency, ideal for phones and tablets.
• Wi‑Fi (AirPlay, Chromecast, DLNA): Longer range, higher bandwidth, excellent for multi‑room setups.
• RF (2.4 GHz or 5.8 GHz): Similar range to Wi‑Fi, often used for outdoor or garage installations.

Each method has its own pros and cons, which we’ll compare later.

What You Need to Know About Your Speakers

Before you buy an adapter, check the speaker’s specifications:

• Impedance (Ohms): Most home speakers are 4‑8 Ω. The receiver’s output must match this range.
• Power handling (Watts): Ensure the adapter’s amplifier can comfortably drive the speaker without distortion.
• Connector type: Most wired speakers use binding posts or spring clips for speaker wire; a simple pair of banana plugs or screw terminals will do.

If you’re unsure, the speaker’s manual or a quick online search (e.g., “Can you make wired speakers wireless”) will usually list these details.
