Wired and wireless audio inputs: with stereo RCA/3.5mm AUX audio input and microphone pick up, work well with most audio devices such as phone, computer, CD players, or speakers etc., very suitable for home/office/studio to dynamically decorate your auditory feast.
Excellent sound and free settings: with 100K high-impedance input circuit, ensuring clean sound without any audio rendering when using line inputs. The color and light level of backlight also can be adjusted freely, perfectly match with different styles of audio device and environments.
Advanced AGC algorithm and better display: AGC ensures ideal visual effects even the input signal is in a small to large range, avoid that no display when input low signal and display in full screen when input high. With gain adjustment even can set the swing range of pointer, easily to control most input signals and achieve better beating effects.
VU56 PRO is the original and upgraded music spectrum designed by Douk Audio. 56 bit in per channel, 112 bit stereo display, ultra-high resolution, easily to see the music level status in real time, every slight change of sound can be shown visually, with much kinds of display effects to dynamically decorate your listening enjoyment.
Unique and attractive design, besides MIC pick-up, VU56 PRO also can be used as an audio converter / splitter with its RCA and 3.5mm AUX inputs and outputs. All interfaces are gold-plated to ensure the tight connection, effectively reduce the sound transmission loss, provides both visual and auditory feast.
Two display mode, PPM (peak programmed meter, 0dB=1.5Vpp) and VU (volume unit, 0dB=0.775Vrms) mode, to satisfy different display requirements. The color of main bar and peak LED can be switched green or red freely, and it also supports 8 kinds of display effects to get much fun and higher play-ability.
