Product description:
You have a line level signal source (TV audio, MP3 player, Video game, mobile phone, tablet, computer, record player), but desire louder sound or bigger volume?
A powerful signal amplifier receiver or volume control, you may need a long line connecting TV audio and the receiver on the other side of the room to provide high gain through any line level signal source, allowing longer cable operation or requiring “buffer” to amplify the lower volume. You may use it between the line level signal source and power amplifier as a signal amplifier, 3.5mm + RCA port matches almost all product interfaces.
The product improves the sound amplification and reduces ground noise by controlling the signal, and it has large dynamic range without produce cracking. It controls output volume through a sensitive volume knob, the output of the headphone interface can drive 16Ω-600Ω headsets, and uses AC9V transformer for power supply to ensure full power.
