### ⭐⭐⭐⭐⭐ Review
*by M***K on 14 July 2025*

I have a Samsung The Frame TV on the wall, connected to a Panasonic PMX-802 mini hifi via a long cable. TV only has digital optical sound out. Using coax extenders, the sound was too low volume through the amplifier with no opportunity to adjust base levels at the TV or amp. Using Optical to 2 x RCA stereo at the TV and the Aux analog input on the amp also led to a low volume since the Aux input is insensitive (2V) and there was a low hum due to the long cable. This pre-amp has solved the problem. Using just a 5V USB power supply (not included) it whacks out enough signal (at near max volume setting) to get decent sound level out of the Panasonic, similar to the radio and other inputs. No sign of hum. Bit pricey, but it's decently built and has solved my problem.
