Voltage: double ac15v-18v note: low voltage will have ac sound, high and 15V will do.The method of reducing noise -- connect the input ground with the shortest (as far as possible shielded) thick line, and then introduce the connection to the housing or heat dissipation or large area of conductor;Circuit board size: 117X68MM(excluding potentiometer)Potentiometer function: 3D, bass, high pitch, balance, volumeDistance between potentiometers: 25MMTwo switching functions: 3D switch on the left and equal loudness switch on the right (LM4610 is wide praise audio enthusiasts LM1036 and upgrading of products, the chip quality smooth and natural, simple peripheral circuit, the function is perfect, in addition to the excellent performance of double track dc voltage to adjust the volume, high and low, balance, and other functions, but also has such as the loudness and 3 d surround sound processing functions, and may, according to the user's interests, the three-dimensional (3 d) stereo sound field to the perfect state.1.The main parameters of LM4610 are as follows:Ending zoom: 3 timesLow input impedance to 30 k Ω, low output impedance of 20 Ohm;Ending with 75dB;The balance adjustment range is 1 ~ 20dB.The length adjustment (at 40Hz) is + / - 15dB, and the length adjustment (16kHz) is + - 15dB.The total harmonic distortion is only 0.0003.Ending/ending ratio up to 80dB;Ending frequency response width of 250kHz;The maximum input and output voltage of the terminal signal is 1.5v.Ending balance error less than 1.5db;The common-mode rejection ratio of ending power source is 60dB.colour:blueMaterial:plasticsize:117X68mmPackage Contents:1*Amplifier boardOnly the above package content, other products are not included.Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
