What You Will Need

Step 1: Connect the Fire TV Cube to Your TV

Place the Fire TV Cube near your TV. The 3rd Gen model is a compact cube that sits next to your entertainment center rather than plugging into an HDMI port directly.
Connect the included HDMI cable from the HDMI port on the back of the Fire TV Cube to an available HDMI input on your TV.
If you want to control your cable box, soundbar, or A/V receiver with the Fire TV Cube, connect the HDMI output of those devices to the Fire TV Cube's HDMI input port. This enables HDMI pass-through so you can switch inputs with voice commands.
Plug the included power adapter into the Fire TV Cube and connect it to a wall outlet.

Turn on your TV and switch to the HDMI input where the Fire TV Cube is connected.
The Fire TV Cube will boot up and display the Fire TV logo.
The Alexa Voice Remote (included) should pair automatically. If it does not, press and hold the Home button on the remote for 10 seconds to initiate pairing.
Select your language using the remote's navigation ring.

The Fire TV Cube will scan for Wi-Fi networks. Select your network and enter the password.
The 3rd Gen model supports Wi-Fi 6E, so if you have a Wi-Fi 6E router, you can take advantage of the 6GHz band for the fastest, lowest-latency streaming.
For the most reliable 4K streaming, consider using the built-in Ethernet port on the back of the Fire TV Cube. Connect an Ethernet cable directly from your router to the Cube.

The setup wizard will prompt you to sign in to your Amazon account.
You can sign in directly on-screen using the remote or use the faster method: visit amazon.com/code on your phone or computer and enter the code displayed on the TV.
Once signed in, the device will sync your preferences, apps, and purchased content.

The Fire TV Cube (3rd Gen) can control your TV, soundbar, and other devices using built-in infrared (IR) blasters and HDMI-CEC.

During setup, the wizard will guide you through configuring TV controls. Select your TV brand from the list.
The Fire TV Cube will send a test signal. Confirm whether your TV turned off and on correctly.
If you have a soundbar or A/V receiver, set it up as well so Alexa can control volume and power for your entire entertainment system.
Once configured, say "Alexa, turn off the TV" or "Alexa, volume up" to control your devices hands-free, even when the TV is off.

The Fire TV Cube comes with Amazon Prime Video pre-installed. Navigate to the App Store to install additional services.
Popular streaming apps include Netflix, Disney+, Hulu, HBO Max, YouTube, Apple TV+, and Paramount+. Search for each by name and select Download.
Sign in to each streaming service with your existing account credentials.
The Fire TV Cube supports 4K Ultra HD, Dolby Vision, HDR10+, and Dolby Atmos audio when available from the streaming app and your TV supports it.

The Fire TV Cube has built-in far-field microphones, allowing you to use Alexa hands-free without the remote.

Say "Alexa, play Stranger Things on Netflix" to launch content by voice.
Say "Alexa, show me the front door camera" to view compatible smart home cameras on your TV screen.
Say "Alexa, what's the weather?" to display weather information even while watching content.
The built-in speaker lets Alexa respond even when your TV is off, effectively making the Fire TV Cube a standalone Echo device.

The Fire TV Cube (3rd Gen) features an octa-core processor, making it the fastest Fire TV device. Apps and menus load noticeably faster than previous models.
Use the Super Resolution Upscaling feature to enhance HD content to near-4K quality. Enable it in Settings > Display & Sounds > Display.
If you use a USB webcam, you can make Alexa video calls on your TV screen.
Press the microphone off button on top of the Cube to disable the built-in microphones for privacy.
