The Hollyland 2/4 Wire Converter (Model: HL-WC01) is a rugged, compact system utility designed to bridge legacy wired party-line intercom hardware with modern 4-wire digital communications.

In broad television, theatre, and industrial event grids, matching different audio standards can cause level drops or feedback loops. This bidirectional converter handles the cross-translation automatically, maintaining pristine wideband audio quality in both directions.

Understanding the Conversion

Wired intercom infrastructures generally fall into two categories. This converter acts as an active, real-time translator between them:

  • 2-Wire Systems (Party-Line): Used by brands like Clear-Com, RTS, or Altair. They transmit power and bidirectional (two-way) talk/listen audio down a single pair of wires within a standard 3-pin XLR line.

  • 4-Wire Systems (Matrix/Digital): Used by high-end digital matrix platforms, broadcast consoles, and wireless hubs (like the Hollyland Solidcom C1 / C1 Pro Hub or Syscom 1000T). These split incoming and outgoing audio lines onto entirely independent pairs of pins (one path exclusively for input, one exclusively for output).

Core Performance Features

  • Intelligent Auto-Nulling Circuitry: The biggest hurdle in 2-to-4 wire conversion is line echo caused by impedance mismatches. The converter features a dedicated, front-panel AUTO NULL button. With one click, the device generates an internal test tone, analyzes the connected line impedance, and drops echo levels out of the track automatically.

  • Power-Free Party-Line Drawing: The converter can extract its operational power directly from an active 12V to 36V DC 2-wire intercom line. You do not need to hunt for an external wall outlet on a busy production floor. (Note: If the 2-wire side doesn't provide power, it can also run off standard USB-C bus power).

  • Distance Wire-Length Compensation: Built with internal DIP switches on the chassis to account for high-frequency signal roll-off over long cable runs. Users can toggle distance compensation steps to optimize audio performance for cable lengths spanning up to 656 feet (200 meters).

  • Independent ±6 dB Gain Trimming: Features independent physical gain adjustment switches for both the 4-Wire Input and 4-Wire Output stages. This allows technical directors to balance varying audio volumes between different manufacturer systems.

  • 6-Segment Real-Time LED Level Meters: Dual LED level strips provide instant, scannable visual feedback for signal inputs and outputs, flashing green for optimal paths and shifting to red to warn of audio clipping.

The Auto-Nulling Status Indicator

When initializing a system, click the physical AUTO-NULL button on the front face. The integrated LED color ring provides real-time diagnostic feedback:

  • Cyan (Blue-Green): Idle state / calibration has not been performed yet.

  • Green: Calibration successful. Echo paths have been calculated and suppressed.

  • Red: Calibration failed. The device detected active crosstalk, a terminal short, or open open-ended cables. Check your XLR connectors and re-run.

Ecosystem Integration Best Practice: If you are hooking this up to cascade a Hollyland Solidcom C1 / C1 Pro Hub with an existing wired Clear-Com setup, wire the 4-wire ports of this converter to the 4W RJ45/XLR terminal on the Solidcom Hub, and the 2-wire side to your party-line. Turn off all microphones on the beltpacks before hitting AUTO-NULL, as background room ambient noise bleed can distort the accuracy of the acoustic echo measurement.

Great no shows for people with larger feet
Size: Large, Color: (001) Black / Black / Castlerock
Some of my favorite socks!! Great quality, fit, and material. I love that they don't slip down in my shoes, especially considering I have larger feet. I also love that Under Armour offers larger sizes in their socks considering everyone in our household has much larger feet than others.

Best liner socks EVER
Size: Medium, Color: (348) Silica Green / Silica Green / Hydro Green
I have them in every color and used to get them from Sams, but they stopped selling them and I was lucky to find them on Amazon. Got all colors again. They stay, it's all I'm gonna say! And don't show in any of my tennis shoes. Absolutely love them and wear them until they get holes. They last a LONG time too. They're on the thin side and my foot loves them because they tend to get hot. There's no shrinking, they wash great with exception of the white ones I couldn't manage to keep white - they turned a bit greyish.

Well-made and comfortable to wear. Great for golf and other outdoor activities. Like them because they do not show above shoes.

These ACTUALLY stay put all day long - I was skeptical, but am so glad I took a chance on these
Size: Medium, Color: (014) Halo Gray / Halo Gray / Castlerock
I was so skeptical about whether these would stay on my feet all day without sliding down into my shoe - I’ve tried so many socks in the past with the silicone strip on the heel which failed. I’ve owned these for a couple months now and they have never slipped down - they stay put all day! I love the variety of colors to choose from, and the value per pack is great since six pairs come per pack (I thought it was only three when I first purchased and was pleasantly surprised by the additional pairs). They also have perfect thickness - not too warm to wear during the summer months with sneakers; I live in a tropical climate, though, so I’m not sure how they will do in cooler climates. I’ve washed each pair once or twice and the color and quality of the silicone has stayed so far (knock on wood). Overall: high recommend based on my experience so far!
