Description

Tube Indicator Driver Kits 2 Channel Level Indicators Amp for Audio Fluorescents 1. the audio input signal amplitude can be adjusted, VR1 and VR3 to change the input signal amplitude 2. This board is not a preamplifier and has no power amplification. It only uses the way of fluorescent column to show the change of the amplitude of the audio signal, so that the audio signal is changed from auditory to visual (visual effect). 3. The parameters of the two tubes are inconsistent due to the individual differences of the 6E2 tubes. After the lighting, the fluorescence heights of the two tubes are not the same. Therefore, two trimming resistors are set on the driving board, and VR2 and VR4 are used to adjust the fluorescence height of the left and right tubes to achieve Highly consistent fluorescence of the two tubes 4. Pipe connection: The extension of the socket pin has been soldered out, and it is connected to the corresponding terminal number of the driver board according to the color of the lead wire (the delivery is accompanied by a wiring instruction) Model Number: 8286229333 Package Include: DC12V 6E2 Tube Driver Kit x 1 Set
