Quick Answer

Choose the Hollyland Solidcom C1 Pro-4S (avec Hub) if you need a central Hub and a four-headset full-duplex team. Choose the Hollyland Solidcom C1 Pro-6S if you need six headsets and can work without the Hub. Both use DECT 6.0 full-duplex audio with up to 350 m line-of-sight range, so the real decision is team size and whether a Hub is part of your workflow.

What the Hub Changes on the 4S

The C1 Pro-4S (avec Hub) is built around a central Hub unit, which is why it costs more than the 6S despite having fewer headsets. In a DECT 6.0 system, the Hub acts as the coordination point for the team: it manages the wireless link and gives you a fixed piece of hardware to place on a cart, at a video village, or near the director. That matters when you want the intercom anchored to a position rather than relying only on headset-to-headset links.

The 6S has no Hub in the kit. It still delivers full-duplex DECT audio and the same 350 m line-of-sight communication range, but the system is organized around the headsets themselves. For a small crew that moves constantly and has no fixed base, that can be an advantage: fewer boxes, less setup, and no Hub to power or position.

Headset Count and Team Size

The number in each name is the headset count. The 4S covers four users, which fits a compact production team: director, camera operator, sound, and one assistant. The 6S covers six users, which suits a larger floor team or a production that needs separate positions for lighting, grip, and production assistants.

If you are unsure, count the people who must talk continuously during a take, not everyone on set. Full-duplex intercom is most useful for the roles that need to coordinate in real time. Adding a headset later is possible only if the system supports expansion, and the supplied catalog does not list expansion headsets for these kits, so treat the included count as your working team size when comparing the two.

Range, Audio, and Real-World Limits

Both kits use DECT 6.0 in the 1.9 GHz band and are rated for up to 350 m line-of-sight. The 6S adds a stated audio range of 150 Hz to 7 kHz, which is wide enough for clear speech and cues. Line-of-sight is the key phrase: walls, metal structures, and crowded venues reduce practical range, so plan positions with a clear path between users or keep the Hub central when using the 4S.

Neither kit is a long-distance radio system, and the catalog does not state a battery runtime, so check the current manual for charging and runtime details before a full shoot day. For most film, event, and concert work, the supplied range is the relevant figure, and the Hub on the 4S gives you one more tool for keeping that link stable.

Trade-Offs at a Glance

  • Hub vs no Hub: The 4S includes a Hub that centralizes the DECT link; the 6S has no Hub and relies on the headsets. A Hub adds a fixed coordination point but also another device to place and power. Pick the 4S if your workflow has a video village or cart; pick the 6S if the crew is fully mobile.
  • Four vs six headsets: The 4S supports four users and the 6S supports six. The catalog does not list expansion headsets for either kit, so the included count defines your working team. Count the roles that must talk during a take before choosing.
  • Price vs headcount: The 4S with Hub is the higher-priced kit despite having fewer headsets, because the Hub is part of the package. The 6S puts the budget into two extra headsets instead. Decide whether the Hub or the extra headsets solve your bigger problem.
  • Shared range, different setup: Both kits are rated for up to 350 m line-of-sight on DECT 6.0. Walls and metal structures cut that down, so placement matters more than the headline number. Keep a clear path between users, or keep the 4S Hub central.

Product Facts

  • Hollyland Solidcom C1 Pro-4S (avec Hub) – Kit intercom: Full-duplex wireless intercom with DECT 6.0 technology in the 1.9 GHz band, designed for demanding professional environments such as audiovisual production, live events, and concerts, with reliable and secure transmission up to 350 meters. The Hub-based 4S is the choice when you want a fixed coordination point and a four-person full-duplex team with the same 350 m line-of-sight range.
  • Hollyland Solidcom C1 Pro-6S – Intercom: DECT full-duplex wireless intercom with a wide audio range of 150 Hz to 7 kHz and reliable line-of-sight communication up to 350 m, suited to film and TV production, concerts, and similar applications. The 6S gives two more headsets than the 4S and the same range, but without the Hub, so it fits larger mobile crews that do not need a central base.

Which Kit Fits Your Production

Best for

  • Productions that want a central Hub at video village or on a cart
  • Four-person teams that need full-duplex coordination in real time
  • Film, live event, and concert work within 350 m line-of-sight

Not for

  • Crews of five or six who need a headset for every position
  • Fully mobile teams that do not want to place or power a Hub
  • Productions that need coverage well beyond 350 m line-of-sight
