Douk Audio Nobsound Preamplifier Equalizer with VU Meter

This is a listing for the Douk Audio B1 Mini 5-Band EQ Equalizer & Bluetooth Receiver Stereo Audio Mini Preamplifier with VU Meter.

I purchased it new from Amazon and used it occasionally.
I am now selling it due to an upgrade.

I have confirmed sound output with both cable and Bluetooth connections.
The VU meter needle movement is also good. The outer box has some scuffs.

Thank you for your consideration.

⭐︎Description
1. 5-Band EQ Equalizer and Preamplifier Function: Adjust individual frequency bands with 5 bands: 75Hz/400Hz/800Hz/4KHz/10KHz. Each band is processed by an independent operational amplifier to compensate for speaker and sound field deficiencies, and to adjust the balance of high, mid, and low frequencies to optimize various sound sources.
2. Adjustable VU Meter and Bluetooth Input: Dual large VU meters (45mm) driven by a dedicated VU driver chip. The backlight, needle speed, and gain are adjustable, dynamically coloring your audio environment and providing an incomparable visual effect. Added Bluetooth 5.0 input makes it easy to enjoy HiFi music wirelessly.
3. Bypass Design and Balance Adjustment: Features a bypass mode that allows you to turn off the EQ preamplifier, outputting the audio signal directly from IN to OUT without processing. This makes it easy to enjoy the original sound. It also has a left and right channel balance adjustment function to keep the sound field centered.
4. Attractive and Powerful Design: Metal case and aluminum knob processing provide excellent shielding performance. All I/O interfaces are gold-plated to ensure smooth transmission of the original audio signal and minimize signal loss. Mini size and DC 5V operation make it highly portable and easy to use in many scenarios.
