## Description

Important 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. Package Includes: 1 * Audio Spectrum Board 2 * Acrylic Board 1 * 3.5mm audio cable 1 * Power cable 1 * 3.5mm 1-TO-2 Plug 1 * Instruction 1 Set Matching screws and pillars

## Questions & Answers

**Q: Is this plug and play unit?**
A: Hello. Yes. It is a finished product. You only need to connect signal input and power input.

**Q: The clock is very annoying! Any way to disable it, so it only acts as a spectrum display? Thanks**
A: Disconnect from headphone jack when not in use.

**Q: when plugged in to a audio source, Ii have 2 or 3 bars flickering like there picking up some interference. any solutions?**
A: Got something similar happening with many bands even when there is minimal audio input. The problem appears to be a poor connection between the 1/8" plug and the socket on the analyser. What I have done is remove the plug, clean it, re-insert it and check. If that doesn't immediately solve the issue, I twist the plug in the socket until I get it to a position that zero input registers nothing on the analyser.

**Q: What are the unit's dimensions?**
A: 7"  x  2"   x 1"
