VU3 VU meter & audio switcher box is originally designed by Douk Audio As a VU meter, with dual 60*35mm large meter, can dynamically decorate audio environment and provide incomparably visual effects when switching audio signals. As an audio switcher, easily to switch between two amplifiers and 2 pair of speakers, no need to plug in and out cables repeatedly to avoid wearing the contact point of the sockets.

Versatile inputs and preamp output besides Bluetooth 5.1 supports APTX-HD and LDAC, T6PRO with 3.5mm AUX and 2 groups of stereo RCA inputs, multiple devices can be connected and switched at one time and avoid plugging cables repeatedly. Also features its 3.5mm AUX preamp output, another amplifier and active speaker subwoofer can be connected to build 2.1 or multi-channel home theater systems.

Dual VU meter design and balance control based on H7 and helpful advice from our users, H7PRO designed with dual VU meters dynamically swings with changes in the audio signal. Remove the independent volume control of the L R channel but add the balance control, to adjust the balance volume of the left and right speakers for a more even and natural sound.

Simple to Install Exquisite workmanship, easy to install, this pointer VU meter is an important tool in sound equipment, providing users with a user friendly monitoring solution.

Adjustable The VU meter has adjustable horizontal swing and can be compatible with all different types of headboards. The two 500 ohm blue potentiometers on the headboard can adjust the sensitivity of the two headboards respectively, and clockwise rotation can increase the sensitivity.

Multiple inputs and higher compatibility with Bluetooth 5.2 RCA MM phono inputs, compatible with most audio devices such as turntables, phones, computers, tablets, TVs, CD players etc. Besides banana speaker outputs, a 3.5mm AUX output is added to connect another amplifier or active speaker subwoofer to build 2.1 or multi-channel audio system.
