Wireless Box E Wireless Streaming Amplifier for Passive Speakers The Wireless Box E is a compact streaming amplifier designed to transform traditional passive loudspeakers into modern wireless active audio systems. By connecting directly to speaker terminals, it eliminates the need for a separate amplifier while delivering efficient and powerful audio performance. Powered by WiiM OS™, the Wireless Box E integrates seamlessly into modern streaming environments and supports wireless multiroom playback. Setup is simple through the Pro-Ject Home App, which automatically detects the device and guides users through the installation process. Featuring Pro-Ject True Wireless Receiving technology, the Wireless Box E can receive audio wirelessly from compatible Pro-Ject streamers including the Uni Box S3 and Stream Box E. This allows analogue and digital sources such as turntables, CD players, radios and televisions to be distributed throughout a multiroom audio network.   KEY FEATURESProduct TypeWireless Streaming AmplifierStreaming PlatformPowered by WiiM OS™InstallationConnects Directly To Speaker TerminalsFunctionTurns Passive Speakers Into Active Wireless SpeakersWireless Audio ReceptionPro-Ject True Wireless Receiving TechnologyWireless Vinyl StreamingCompatible With Pro-Ject T2 WMultiroom AudioSupportedApp ControlPro-Ject Home AppStreaming ServicesAccess To Multiple Music Streaming PlatformsConstructionAluminium Front Panel & Metal ChassisAvailable FinishesSilver Or BlackCompatibilityUni Box S3, Stream Box E, Wireless Box E & WiiM Devices   AMPLIFIER PERFORMANCEOutput Power1 × 25 W @ 8 Ω1 × 50 W @ 4 ΩFrequency Response20 Hz – 20 kHz (< -1.5 dB @ 4 Ω)Signal-to-Noise Ratio96 dB (100 dB A-weighted)Channel Separation-67 dB @ 10 kHzTotal Harmonic Distortion< 0.12% @ 5 W / 4 Ω   WIRELESS CONNECTIVITYWi-FiDual-Band Wi-Fi 802.11 a/b/g/n/acSupported Bands2.4 GHz & 5 GHzBluetooth VersionBluetooth 5.0Bluetooth CodecsSBC, AACStreaming TechnologyWiiM OS™   SPEAKER CONNECTIONSpeaker Outputs4 mm Banana Plug ConnectorsSpeaker CompatibilityPassive SpeakersOptional ExtensionConnect it LS Flex Cable (Sold Separately)   POWER SUPPLYPower Supply22V / 1A DCMains Compatibility100 – 240V, 50/60HzStandby Power Consumption< 0.5 W
