The Philex SLx4P is an aerial amplifier and signal booster that is designed to increase and improve TV, DAB Digital Radio, Cable, Satellite and FM signals. The SLx4P has one input and four outputs, so you could use if to boost a signal to up to 4 TVs elsewhere in the house.
The Philex SLx4P is mains powered and it plugs directly into a mains power socket. You can connect it to a Freeview Box, a satellite receiver, plug your digital TV aerial into it or connect to a DAB or FM aerial. The SLx4P then enhances any signal passed through it. It has one input (which can be used either for a TV signal or for a radio signal) and four outputs. The SLx4P has a variable gain control which allows you to adjust the gain (amplification strength or boost) of the unit from 10 – 20dB. The SLx4P can also just be used as a DAB booster.
