Calrec Audio has been the UK broadcast console standard since the 1970s. Founded in 1964 in Hebden Bridge, Yorkshire, Calrec built its initial reputation supplying the BBC with custom broadcast consoles. Over the following decades, Calrec expanded into commercial UK broadcasting and sports broadcast worldwide. In 2026, Calrec consoles are used on many major sports and entertainment productions around the world, notably in OB trucks. Part of the UK-based Audiotonix group (alongside Allen & Heath, DiGiCo and SSL) since the group was formed in 2014, Calrec continues to develop the Apollo, Summa, Brio, Argo, and Type R lines.
This guide covers the modern Calrec line from a professional broadcast engineer’s perspective.
Calrec Apollo Plus: the flagship
Apollo is Calrec’s large-format flagship console — up to 1,020 channel processing paths on Bluefin2 DSP, surfaces configurable from 8 to 320 faders, and the Hydra2 networking system; Apollo Plus (Apollo+) combines the same surface with Calrec’s ImPulse IP processing core. Apollo Plus installations are found at the largest broadcast facilities and OB trucks worldwide, particularly for major sports broadcast where its routing scale and reliability are critical. Pricing is project-specific and typically well into six figures for large installations.
The defining technical features:
- Hydra2 networking — Calrec’s proprietary audio network, with an 8,192 x 8,192 router core, up to 512 audio channels per Hydra2 port, and built-in fault detection and redundancy
- Bluefin2 DSP engine (Apollo) or ImPulse IP core (Apollo+) — high-channel-count processing with the headroom for very large broadcast applications
- Direct-bus matrix — every input can route directly to any matrix or aux without intermediate patching
- Surround monitoring — 5.1, 7.1, and Dolby Atmos / 7.1.4 monitoring built into the master section
Calrec Summa, Brio, and Type R
Summa is the mid-tier Calrec console — fixed 12+8, 24+8 or 36+8 fader surfaces, with pools of 128, 180 or (newer generation) 300 channel processing paths, Hydra2 native. Summa is widely deployed in mid-size TV studios, regional broadcast facilities, and OB trucks where Apollo Plus’s footprint and cost are excessive but full Hydra2 integration is required. Pricing is on request.
Brio (launched 2016) is the compact Calrec — Brio 36 (36-fader dual-layer surface) and the smaller Brio 12, with integrated I/O and DSP, designed for smaller broadcast applications (regional radio, small TV studios, university broadcast, corporate). Brio (along with the compact Type RT) is the most accessible entry into the Calrec ecosystem; pricing is on request.
Type R (introduced 2018 as Calrec’s first native IP product) is Calrec’s modular IP console — fully ST 2110-compliant, with a touchscreen-first surface approach designed for radio and TV applications where the operator workflow is largely software-driven. Type R competes with Lawo mc² 36 for new IP-native installations.
Argo is Calrec’s newest flagship-tier IP-native console (introduced 2022), positioned as the ST 2110 successor to Apollo for new builds. Argo (Argo Q, Argo S and later Argo M) runs on an expanded version of Calrec’s ImPulse IP core, with up to 2,496 channels on a single console and up to 96 faders in a modular surface. Pricing is project-specific.
What makes Calrec distinct
Several factors explain Calrec’s dominance in the highest-stakes broadcast applications:
1. Sports broadcast specialization. Calrec consoles are designed around the specific demands of multi-feed sports broadcast — multiple concurrent program feeds (international, host broadcast, world feed, talent isolation), large numbers of intercom channels, and the need for bulletproof reliability under high-pressure live conditions. The direct-bus matrix and Hydra2 routing scale are specifically suited to these applications.
2. Hydra2 reliability. Hydra2 has a strong reputation for reliability in live production. Its built-in fault detection and redundancy options are a key reason it is chosen for major sports broadcasts where any audio dropout would be catastrophic.
3. Operator ergonomics. Calrec surfaces are designed for fast, eyes-up operation in broadcast environments. Channel strips have a consistent layout across the product line; operators trained on a Brio can transition to an Apollo Plus with minimal retraining.
4. UK broadcast incumbency. For UK-based broadcast operations and UK-trained engineers, Calrec is the default specification. This creates a self-reinforcing cycle in which UK broadcast facilities continue to specify Calrec to maintain workforce continuity.

Calrec vs Studer vs Lawo
Among the three European broadcast specialists, the choice typically comes down to:
- Calrec — the right answer for major sports broadcast, UK-incumbent facilities, and applications requiring the largest channel counts with bulletproof reliability
- Lawo mc² — the right answer for new IP-native installations, German-speaking territories, and integrated audio/video workflows
- Studer Vista — the right answer for European public broadcast incumbency, post-production, and applications where the Vistonics interface is preferred
In US broadcast, Calrec is widely used in network facilities and sports OB trucks, alongside Lawo, while Avid VENUE S6L and Yamaha Rivage are common for music performances and entertainment events.
Where Calrec fits in a 2026 facility
Calrec is the natural specification for:
- Major sports broadcast OB trucks (NFL, Premier League, Champions League, Olympics, World Cup)
- UK broadcast facilities at every scale
- Large international broadcast operations (multiple language feeds, world feed production)
- Music and entertainment broadcast where reliability is paramount

Where to buy Calrec consoles
Calrec systems are sold primarily through factory direct (Calrec UK) and authorized broadcast integrators. Smaller Brio and Type R systems are also sold through Calrec’s authorized dealers; general retailers such as Thomann or Sweetwater do not stock them as standard items. Major Apollo Plus, Summa, and Argo installations go through Calrec’s regional offices (Calrec North America in particular) with custom integration and on-site commissioning. For UK broadcast specifically, Calrec maintains direct relationships with virtually every major broadcaster.
Bottom line
Calrec remains the broadcast console of choice for the world’s most demanding sports and entertainment broadcasts. Apollo Plus is the flagship; Argo is the IP-native flagship for new builds; Summa and Brio cover the mid and compact tiers. For UK broadcast and major sports productions, Calrec is often the only correct answer.
