VU1 PRO VU meter & audio converter box is originally designed by Douk Audio: As a VU meter, with LINE and microphone inputs, can be matched well with most audio devices such as phone, computer, CD players, or speakers etc. As an audio adapter, easily to convert XLR (RCA) input to RCA (XLR) output and with IN/OUT switch, no need to plug in and out cables repeatedly to avoid wearing the contact point of the sockets.
Multiple practical functions and easy adjustments: Gain adjustment, to adjust the gain of input signal, that is the swing range of pointer to get differnt display effects. Delay adjustment, to adjust the sensitivity of pointer that is the speed of pointer beating to adapt to different music styles.
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.
Powerful design and strong compatibility: all channels adopt fully isolation design, each channel's GND is independent without mutual interference. Supports all kinds of amplifier such as BTL / class A / class B / class D digital amplifier / tube amplifier etc.
As an analog VU meter, with wired stereo RCA input and wireless microphone inputs, can be matched very well with most common audio device such as mobile phone, computer, CD players, or speakers and so on, very suitable for home/office/studio system to dynamically decorate your auditory feast.
As a 4-way audio splitter box, VU2 can work in 4-IN-1-OUT to compare the sound quality of differet audio source among mobile phone, tablet computer, TV, CD player, DAC etc., also can work in 1-IN-4-OUT mode to do contrasts among preamp, headphone, power amplifier and active speakers etc. 4 channel can input at the same time to mixer different audio source, also can output at the same time to satisfy the requirements of monitoring or recording.
【High sensitivity 】Pointer type digital VU meter head is easy to carry and store, the pointer is sensitive, and the measurement is accurate, can directly display the measurement results.
【High performance】The VU meter is stable and reliable performance, high display accuracy, backlight. Easy to install and use, can improve work efficiency, save time and energy.
【AGC mode】: AGC ensures ideal visual effects even when the input signal ranges from small to large, avoiding no display when the input signal is low and full screen display when the input is high. The gain adjustment even allows you to set the swing range of the pointer, easily controlling most of the input signal to achieve better beat effects.
【Material】: All metal housing, CNC machined panel, solid stepless adjustment knob, all interfaces are gold plated to ensure a tight connection to ensure smooth transmission of the original audio signal.
VU Meter Features:Standard conditions temperature: 20 Celsius, humidity 70% . Can also tested under normal temperature and humidity.The degree pointer at the scale to the scale sensitivity of 1000 ± 10% (full scale position);Internal impedance :800 ohm ± 10%;Insulation impedance meter outside plus the electrical with 500V plus 50M ohm meter
Electrical insulation of the impedance is 500V of the insulation . Pointer to overlap with the -scale tolerance of ± 1mm balanced meter using a standard position and 90 degrees to allow the range of ± 1mm;Pointer to mount the current plus three the full scale current, and slowly reduced to the the electric degree 1/2 ,
