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.

An immature take on Peter Parker only suitable for the most immature reader
Format: Kindle
Someday, Marvel Comics won't be controlled by white male Boomers/GenXers who make Peter Pan look well adjusted and who incessantly try to recapture a childhood that never actually existed while believing women have cooties and adult relationships are icky. But until then, we get Amazing Spider-Man by Joe Kelly, whose writing is the living embodiment of the Steve Buscemi "How do you do, my fellow kids" meme. This run is boring, trite and cliched. You could probably get a more insightful and original story by asking ChatGPT to write one for you. The only thing going for the run - so far - is that Kelly at least isn't outright aggressively antagonizing the reader unlike the previous writer. It's just...bland and mediocre.

Great delivery, great price, great book!
Format: Hardcover
Must have for any Batman/DC comics fan. I’m not much of an art snob, but the pictures in this book are stunning. The story is wonderful.
