It features a frequency response of 20Hz-20KHz and an adjustable bass gain knob, making it ideal for integrating aftermarket amplifiers with factory car audio systems lacking RCA outputs. ## Description Functions: 1. Efficient audio conversion. Lossless output. 2. Eliminate the electricity. Enhance the bass. Improve sound quality. 3. Easy installation. See the pictures for the installation tutorial. Voting options: 1. Adjust the input level of the amplifier to the minimum value. 2. Adjust the input level of the 2-channel line output converter (H-2) to the minimum value. 3. Increase the volume of the host. When the speaker system has the maximum undistorted performance, the system is the best tuning program. 4. If you adjust the volume of the host to the largest, but the speaker system does not reach the maximum undistorted performance, simply increase the level of H-2 until the speaker has the maximum undistorted performance. 5. If you adjust the level of the H-2 to the largest, but the speaker system does not reach the maximum undistorted performance, simply adjust the level of the amplifier until the speaker system has the maximum undistorted performance. Note: When you do not use the REM control, you do not need to connect the red, black and blue cables. Review: Parfait - Dépanne bien sans trop de perte sonore Review: Tut was es soll. - Bei mir im Polo habe ich die Fahrzugbatterie hinten drin und das ganze anschließen geht einfach. zuerst die Signale der hinteren Lautsprecher abgreifen und alleine das reicht aus um ein Chinch Signal zu bekommen. Die anderen 3 sind nur Plus und Minus anklemmen an der Batterie der letzte ist das "simulierte" Ein und Ausschaltsignal vom Radio das zum Verstärker geht. ## Features - Package Content: 1 x 2 Channel Power Output Converter and 1 x Cable - This converter has the function of RCA high to low.
