Douk Audio VU2 Dual VU Meter 4-Way Splitter Review

The Douk Audio VU2 is a dual analog VU meter combined with an audio splitter and switcher box, priced at $179.00 in Light or Blue style. It is an original Douk Audio design that pairs wired stereo RCA input and microphone pickup with a four-channel switchable array, presented in a cool black case with colorful indicators.

As a meter, the VU2 shows music levels on dual analog needles, reading from the RCA input or the microphone. As a switcher, it works two ways: in 4-IN-1-OUT mode it compares the sound quality of up to four sources, such as a phone, tablet, TV, CD player or DAC, and in 1-IN-4-OUT mode it contrasts up to four destinations, like a preamp, headphones, a power amplifier and active speakers. The four channels can also input simultaneously to mix sources or output simultaneously for monitoring and recording, all without re-plugging cables and wearing out connector contacts.

The meter section is tunable in ways most displays are not. Gain adjustment sets the swing range of the pointer and can fix the 0dB position for recording use, handled digitally by the microcontroller so it has no physical contact with the audio signal. Delay adjustment changes the pointer's sensitivity and beating speed to match slow ballads or fast rock, and the ACG and DB modes select the scaling behavior. The USB interface powers only the VU meter's drive board; the meter reads the signal from the I/O path without influencing the audio circuit. All terminals are lengthened gold-plated pure copper with large contact areas for ultra-low signal loss, and a remote control is included.

One compatibility note from Douk Audio: while the VU2 works with most audio devices, compatibility cannot be guaranteed 100%, and if common ground noise appears in a given setup, an isolation module between the VU2 and the device is the recommended fix.

Specifications

How it compares

The VU2 is the original of the Douk Audio VU2-PRO 4-Way Audio Selector review ($199.99, $20.99 more). The PRO keeps the dual analog meters and the 4-IN-1-OUT and 1-IN-4-OUT RCA routing, then adds calibrated meter ranges (0, -10 and -20dB, on a -50dB to +10dB scale), AVE and PEAK response, XLR pass-through, 5-15V trigger jacks and 35 backlight colors, and it lists a USB-C supply of 5V at 2A or more with an adapter in the box. The VU2 page lists gain and delay adjustments with ACG or DB scaling instead, a Micro USB 5V supply and no adapter.

For less, the Douk Audio VFD253-PRO 4-Channel Selector review ($139.99, $39.01 below the VU2) offers the same four-way RCA routing with a 25 x 15 VFD spectrum display and clock instead of needle meters, plus an adapter in the box; the Douk Audio L3 3-Channel Loop Switcher VU Meter review ($109.99) is a three-slot effects loop with two 45mm meters and a bypass. Choose the VU2 for needle meters on a four-way RCA box with a microphone input and gain and delay tuning; choose the VU2-PRO for balanced pass-through or a calibrated scale; choose the VFD253-PRO if you would rather have a spectrum display and clock.
