About the [Pre-Sale]Douk Audio MC303 3-In 3-Out XLR Audio Switcher with Actual Level VU Meter
From the product page on doukaudio.com.
· 3-In 3-Out XLR Switching: Keep up to three balanced XLR sources and three output devices connected, so you can switch setups without repeatedly swapping cables. Select one A/B/C input and route it to Output 1, 2, or 3—or run three outputs simultaneously for a more flexible HiFi system.
· Read the Signal Behind the Swing: Calibrated dual VU meters with purpose-built driver circuitry support precise response. For actual readings, use 0 or -10 dB gain; at 0 dB gain, 0 dB corresponds to 0.775 Vrms. Gain adjusts continuously from -10 to 0 dB for different signal levels, while 35 colors and five brightness levels to shape the look from a warm vintage glow to a cool modern vibe.
· Preserve Your System Sound: Relay-based mechanical switching routes the balanced XLR signal without added amplification, attenuation, or processing. A 47 kΩ VU branch keeps loading low, while gold-plated XLR contacts support stable, clean signal transfer with minimal impact on your system sound.
