Douk Audio VU22 Dual Analog VU Meter Review

The Douk Audio VU22 is a dual analog VU meter and sound level display priced at $89.99, built to decorate a home, office or studio system with two 45mm moving-needle meters behind a DB-style panel. It comes in black or silver with a CNC-machined all-metal case, measuring 177 x 115 x 59mm at 661g.

Inputs cover both worlds: stereo RCA and 3.5mm AUX for a wired signal from a phone, computer, CD player or speakers, plus a microphone pickup for wireless listening to the room. A 100K high-impedance input circuit ensures line signals pass through cleanly with no audio rendering, and stereo RCA and 3.5mm outputs are provided for pass-through. Backlight color is switchable and its brightness adjustable, so the display can match different audio devices and environments.

The display logic uses an AGC algorithm that keeps the visual effect ideal whether the input signal is small or large, avoiding the no-display-at-low-volume and full-screen-at-high-volume problems. Gain adjustment lets you set the swing range of the pointers for the best beating effect on most input signals, and the accepted input voltage range is 0.1-2Vrms across a 5Hz-20kHz response. Settings are saved after power-off, and all interfaces are gold-plated for tight connections and minimal signal loss.

Douk Audio offers two operating notes. The VU22 needs a separate USB power supply at DC 5V / 1A or more over Type-C, and should not be powered from a computer's USB port or share its supply with the audio source, as that causes common-ground noise. The RCA and 3.5mm inputs are wired in parallel, so do not connect both at once or the signals will mix. The company also notes that though the VU22 is compatible with most audio devices, if common ground noise does appear, an isolation module between the VU22 and the source is the fix.

Specifications

How it compares

At $89.99 the VU22 is one of the group's two analog-needle meters, with two 45mm meters and a case in black or silver, and the one whose page lists the most connections: stereo RCA, 3.5mm AUX and a microphone in, stereo RCA and 3.5mm AUX out, a 100K input impedance and a 0.1-2Vrms input range. The Douk Audio VU360 costs $99.99, which is $10.00 more, and is the other analog meter: one oversized 75mm dual-needle meter, a 3.5mm AUX or microphone input and a 3.5mm AUX output, in yellow or white versions with preset color families; its page lists no input impedance or input range. The Douk Audio VU56PRO costs $69.99, which is $20.00 less, and swaps needles for 56 LED segments per channel with switchable PPM and VU scales, RCA and 3.5mm AUX in and out plus a microphone, and a maximum effective input of 1.8Vrms.

Who it suits: the VU22 fits a desk or rack that wants needle meters and a pass-through between a source and an amplifier, or the microphone to follow the room. The page says it works with most, not all, audio devices and suggests an isolation module if you hear common-ground noise. Skip it if you want a power supply in the box: the page lists a USB cable and no adapter.

Shipping, returns and warranty

• Shipping: Douk Audio's current shipping page says orders are generally processed no later than the next business day and arrive in 2-8 business days, with duties, taxes and customs fees included in the checkout price unless noted otherwise.
• Older shipping terms are still online: airmail at 10-25 days for parcels under 2 kg, DHL, UPS or FedEx at 5-8 days above that, and a line saying the store is not responsible for import duties. Check the delivery estimate and any duties at checkout.
• Returns: ask within 30 days of delivery and wait for approval before sending anything; an approved return has to ship within 7 days. Items need all packaging and accessories and no excessive wear, or the store can refuse them or refund part of the price. Refunds go to the original payment method after inspection.
• Not refunded: original and expedited shipping, duties, taxes and customs charges, unless the law requires it or the store made the error. The return page does not say who pays return postage, and the older refund page excludes mistaken orders and change-of-mind returns from free after-sale service.
• Warranty: 24 months from purchase for manufacturing defects, with free repair, a replacement unit and free shipping both ways for covered repairs. Drops, liquid, DIY repairs, lightning, extreme temperatures and misuse are excluded (partial fees may apply), and damage from weak packing on the way back may not be covered. The older refund page still says 1 year.
• Seller: the site is run by Shenzhen Anba Technology Co., Ltd (Shenzhen, China) and HONGKONG LONGSHENG Import and Export Trading Co., Limited (Hong Kong); support is by email at [email protected]. These terms cover orders placed on doukaudio.com; other sellers apply their own.

For this product, the page lists shipping to US, UK, EU, AU and Other, offers Black and Silver, and shows Free Shipping, 2-8 Days Arrival, 30-Day Return and 2-Year Warranty badges near the price.
