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.

Go big
Color: Black
I had a very small holder that barely held anything, the I stumbled on this in the small size, which I almost bought because it was a little bigger than what I had. Then I saw this one and I'm glad I bought the larger one because it holds everything! I even bought a glass container for the dish soap. Fits perfectly in the space. I also like the idea of the stone to absorb water instead of it dripping in a tray that runs through a spout into the sink.

Less mess, more style!
Color: Gold, Color: Gold
So happy with this purchase! I was a tiny bit wary buying an item without any reviews yet, however I saw that the other caddies from this brand all had many positive reviews and seemed to be good quality. The diatomaceous earth base of this caddy elevated this option to me, so I went for it. I've had it out for a few days and am extremely happy that I went with this option! It absorbs water super quickly, so there are no more rings and residue left on the top of my sink, and it makes my countertop look that much more cute and put-together. Heads up it is a little deep compared to some other trays/caddies; I knew this ahead of time so planned to put it directly to the side of my sink so that it did not overlap. I think the size is worth it, since it accommodates about 2 soap products and has plenty of adjustable room for bottle brushes, sponges, drain stoppers, and whatever other items you need. Overall, I highly recommend!

Sturdy and does the job well.
Color: Black
Very stable. Have a narrow ledge on my sink and it balances great without falling. Holds all my sponges and brushes and dish soap. Hasn’t rusted and I’ve had it for a while now. Looks nice on my sink. Keeps my counters dry and my sponges mold free.
