SpeaKa Professional SP-WLME-400 is an HDMI wireless transmitter/receiver set that enables cable-free transmission of Full HD video signals at 1920 x 1080 resolution over the 5 GHz band. Designed for short- to medium-range wireless video distribution, the set supports a maximum line-of-sight range of up to 180 m and includes a loop-through HDMI output on the transmitter for local monitoring or daisy-chaining to additional displays. The kit is suitable for installing a flexible AV link where running HDMI cables is impractical or undesirable, and it operates with a focus on straightforward connectivity between source and screen.

Advantages

The SP-WLME-400 provides wireless 1080p transmission over the 5 GHz frequency to reduce interference common on lower bands, while the included loop-through HDMI output allows a source to feed both the wireless transmitter and a local display simultaneously. Setup requires only basic cable connections and power to the two units, enabling rapid deployment in presentation spaces, meeting rooms, classrooms or retail environments. The product combines a compact form factor with a practical operating range suitable for many indoor and semi-open indoor scenarios.

How to use

Connect the HDMI source (such as a laptop, media player or set-top box) to the transmitter HDMI input and connect the transmitter to power. Use the loop-through HDMI output on the transmitter to connect a local monitor if required. Place the receiver near the target display, connect it to the display's HDMI input and power the receiver. Power both units and allow them to pair according to the included instructions; pairing and link status are indicated by the unit LEDs. Adjust placement to maintain a clear line of sight or reduce obstacles between transmitter and receiver when possible.

Usage recommendations

For reliable operation, use the 5 GHz band free from heavy Wi‑Fi traffic and position units with minimal obstructions. Avoid placing the transmitter or receiver behind large metallic objects or inside enclosed metal cabinets. For installations approaching the maximum range, perform a site test to verify signal stability and quality before final mounting.
