Description: The input power is 5VDC.Dedicated VFD spectrum display, Resolution 25×15.Support 32HZ-16KHZ frequency sweep,Ensure the accuracy of each band.The falling speed of the light bar, the holding time and the falling speed of the peak can be adjusted separately.Real output and smooth outputⅠ/ smooth output Ⅱselection.Clock brightness can be adjusted 3 levels.Extended function interface Infrared, sound source selection, volume motor control, volume key, volume display, standby control.Accurate clock display function. SD2405AL built-in crystal oscillator, the chip can ensure that the clock accuracy is +5ppm (at 25+1 degrees Celsius), the annual error is less than 2.5 minutes.Software AGC + custom output curve, in order to ensure that the input signal in a large range of output effect is ideal.Custom frequency band display to ensure that even the 25 segment, can fully display the audio frequency range. Specific operation:Normal mode:1. Single clickUP - Mode change DOWN - Mode changeOK - Bottom line display or no in spectrum mode2. Double-clickOK - Switching real / smooth I/ smooth II output3. Three-clickOK - Menu effect switch, right -left transition / up - down transition / mid folding open4. Four-clickOK - Volume display function on or off5. Five-clickOK - Switch the extended port output level, high or low level6. Composite keyUP+DOWN -2 SecondsA. (In the spectrum mode)The external ports are switched on or off (including infrared interface, audio source selection interface, volume motor control interface, volume key interface, standby control interface).B. (In the clock mode )Switch the clock display effect.UP+DOWN+OK -2 Seconds，Enter the screen self-test program, press the OK button 1 second to exit.UP+DOWN+OK -5 Seconds，Enter infrared learning function, press OK button to exit in 1 secondUP+DOWN+OK -10 Seconds，Infrared code recovery factory settings (the default is Tmall infrared remote control).7. Long press buttonUP - Clock mode (or standby mode) Brightness increase(Note, if you need to increase to the brightest level, press for about 10 seconds, if the standby brightness is too high, it will cause uneven of VFD, the highest brightness level is not recommended).DOWN -Clock mode (or standby mode) Brightness reductionSpeed setting mode: (In normal mode, press the button for 2 seconds to enter, press the button for 2 seconds to exit).OKa. The falling speed of the light bar (15 optional)b. The holding time of the peak (15 optional)c. The falling speed of the peak (15 optional)d. Output selection (Real output / smooth I output/ smooth II output) Loop in these functions.UP - Time increases, Speed decreasesDOWN - Time decreases, Speed increase Clock Setting mode ：(In normal mode, press the button for 5 seconds to enter, press the button for 2 seconds to exit) .Single clickOK - Switching hours / min / sec / year / month / dayUP - Hours / minutes / sec / year / month / day increase.DOWN - Hours / min / sec / year / month / day decrease. Other function operation：Factory default.OK -10 Seconds. Notes：1. Because of the working conditions of VFD, there is a DC high voltage of about 38V, so don't touch the VFD pins when it is working.2. Because of the characteristics of VFD, long working brightness will be attenuated, so it will become uneven, is a normal phenomenon.3. Because the clock module is selected parts, if there is no clock module installed, then the relevant clock function instructions are invalid.4. When there is no clock function, no signal input and button operation, will enter standby state and display standby characters, in the external port closed setting , after 1 minutes it will close the filament power supply and VFD high voltage. Enter deep standby status. Auto wakeup when there is a signal input or press button operation.The spectrum center frequency band is shown in the figure.
