Hollyland Spares - Walkie-Talkie Converter-Box

The Hollyland Walkie-Talkie Converter-Box (Model: HL-CB01) is a high-performance audio interface hub engineered to bridge traditional analog two-way radios (walkie-talkies) with modern Hollyland digital wireless intercom networks.

On large-scale broadcast sets, security operations, and live industrial events, production crews are often split between wireless headsets and analog radios. This converter bridges that gap, seamlessly routing two-way radio channels into the master intercom loop so security, medical, and production personnel can talk to camera operators and directors on a unified network.

Core Integration & Audio Management

The converter interfaces natively with any base station or audio ecosystem featuring standard 4-wire configurations, functioning as an external expansion box for the following master hubs:

• Solidcom C1 & Solidcom C1 Pro Hubs

• Syscom 1000T Intercom System

• Mars T1000 Wireless System

Key Capabilities

• Dual Communication Modes (PTT & VOX):

  • PTT (Push-To-Talk): Integrates directly with the physical transmitter mechanisms on connected walkie-talkies to lock open a directional lane when initiated.

  • VOX (Voice-Activated Exchange): Automatically opens the audio gate when the user speaks, featuring an adjustable internal threshold logic frame (>-23dBu) to filter out ambient room rumble before broadcasting voice loops.

• Acoustical Level Balancing: Features built-in signal matching attenuation. Audio signals transferring from the 4-wire interface down to the walkie-talkie lines are padded down by -4dB, while signals coming out of the walkie-talkies up into the intercom loop are boosted by 4dB to ensure level uniformity across different equipment profiles.

• Comprehensive 4-Wire Backplanes: The input panel provides versatile I/O breakout paths, including 3-pin XLR Male & Female inputs, alongside an RJ45 multi-channel data terminal connection port.

Understanding the Cable Variant Profiles (2C, 8C, K)

When purchasing this converter box or sourcing specific spare kits, the baseline converter remains identical, but the suffix designates the precise radio connection wire packaged inside:

• Converter-K: Ships with a K-LEMO walkie-talkie connection cable designed primarily for Kenwood-style 2-pin connector configurations.

• Converter-2C: Includes a specialized 2-Core walkie-talkie cable for specific commercial multi-pin radios.

• Converter-8C: Includes an 8-Core aviation-style cable for interfacing with heavy-duty Motorola-style or professional legacy radio infrastructure.

Deployment Optimization Warning: Because walkie-talkie communication relies on half-duplex transmission (only one person can speak on a channel at a time) while Hollyland wireless headsets operate on full-duplex transmission (everyone can talk simultaneously), you must carefully calibrate your VOX threshold setting if using hands-free voice triggers. Setting the VOX threshold sensitivity too low in a loud environment will cause the ambient noise to constantly trigger the walkie-talkie, locking the channel open and blocking the rest of the crew from using that radio frequency band.
