The Engel MV7127 is an analogue VHF/UHF modulator that enables multiroom audiovisual distribution. It takes the audio and video output from any AV source — DVD player, DTT or satellite receiver, VCR, and similar devices — modulates the signal, mixes it with the antenna RF input, and sends the combined signal through the existing coaxial cable network to additional televisions throughout the home.

Channel selection is performed using push buttons with a display readout, and the RF output level is adjustable. No additional wiring is needed beyond the existing coaxial cable installation.

Key Features

• Accepts RCA audio/video input and RF antenna input simultaneously.
• Single RF output distributes the modulated signal over coaxial cable.
• Frequency range covers 47–862 MHz (VHF and UHF bands).
• Maximum output level of 85 dBμV.
• Channel selection via front-panel push buttons and display.
• Adjustable RF output level (0/−15 dB) and audio input level (+1/±14 dB).

Product Benefits

• Watch content from a single AV source on any television in the home using existing coaxial wiring.
• No need to run new HDMI or AV cables between rooms.
• Compatible with DVD, DTT, SAT, VCR, and other RCA-output sources.
• Weighted signal-to-noise ratio of ≥−55 dB maintains picture clarity on connected televisions.
