Headphone Speaker Amplifier and Stereo Signal Preamplifier with Volume Control

Description

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. 【Product parameters】 Input impedance: 100K Ohm Maximum input level: +14 dBV Output impedance: 47 Ohm of each output channel Frequency response: 20 Hz – 20K Hz Signal to noise ratio: > 107dB Total harmonic distortion: < 0.08% Intermodulation distortion: < 0.01% Input port: stereo 3.5mm socket and RCA port Output port: stereo 3.5mm port and RCA port Power supply: AC9V Net weight: 0.51 kg Gross weight: 0.61 kg Product size: 109 X 79 X 39 mm Packaging size: 185 X 135 X 65 mm Package Contents 1 * stereo signal preamplifier 1 * AC9V power adapter (AWG) line length 100cm Only the above package content, other products are not included.
