Dual Channel LED Sound Level Meter Stereo Music Spectrum Home/Car Audio Display

Item description

Features
  • Dual 24-Level Stereo LED Display: Dual 24-segment RGB LED columns respond to left and right channel levels, bringing music to life with vivid real-time movement. In DB mode, the digital dB display lets you monitor the 3.5mm input signal level in real time.  
  • MIC Pickup & 3.5mm Line Input: Choose built-in microphone pickup for a simple cable-free display, or connect your audio source through the 3.5mm input for more direct and stable signal visualization. Line Input supports both AGC and DB modes, while microphone pickup operates with automatic AGC adjustment.
  • AGC & DB Modes for Different Uses: AGC automatically adapts the LED response as signal level changes, helping maintain a clear and lively display over a wide input range. Switch to DB mode with Line Input to monitor the actual input signal level more directly.
  • Rich Colors & Adjustable Display Effects: Choose from 10 preset color combinations and 4 display effects. Brightness, main-bar falling speed, peak hold time, and peak falling speed each offer 15 adjustment levels, while power-off memory keeps your preferred settings after restart.
  • USB-C Power & Solid Aluminum Build: Upgraded USB-C power makes connection more convenient, while the sandblasted anodized aluminum-alloy housing and black acrylic front panel give the meter a clean, durable finish that fits naturally into desktop and HiFi setups.

Warm Tips
  1. The digital dB readout is available only in DB mode with the 3.5mm Line Input. MIC pickup operates in AGC mode only.
  2. For devices with a 3.5mm headphone/audio output, a wired connection is recommended for a more stable signal and better display response. Keep the source volume above 50%; around 85% or higher is recommended for best results.
  3. When using a 3.5mm splitter, do not split the same output between the level meter and headphones.
  4. For speaker-level car audio signals, use a suitable high-to-low level converter before connection.
  5. Independent USB power is recommended to help reduce possible ground-loop noise.
