“Before, at the Bilbao Fine Arts Museum, 40 people had to queue for 8 minutes in front of three hubs just to hear a guide in three different languages. Today, in the same corner of the underground gallery, for the first time, everyone heard the story behind every painting simultaneously.”

That was the reflection of Carlos Ruiz, Operations Director at TourArte Norte, after wrapping up an intense 8-day art tour. From “fighting for a channel” to “synchronized listening for the whole group,” the transformation came down to one essential upgrade: the Wireless Tour Guide System from Richitek — specifically the RC8860 transmitter paired with the RC2402 receivers.

🏆 Client Profile: Cultural Ferrymen of the Iberian Peninsula

TourArte Norte, a fully licensed travel agency based in Madrid, has spent the last eight years curating deep-dive art and cultural experiences across the Iberian Peninsula. Their clientele aren’t casual tourists — they’re art aficionados who can recite Goya’s brushstrokes, discuss Picasso’s Blue Period, and debate Miró’s symbolism over dinner.

In April 2026, Operations Director Carlos Ruiz signed his first contract with Richitek. From June 8 to June 15, he personally led a demanding 40-person art ensemble: 60% Spanish retired art lovers, 40% from Portugal, Italy, and France. Over eight days, the group traveled from Bilbao and San Sebastián in the north to a contemporary dance theater in Madrid — a true stress test for multilingual guiding.

📡 Solution: Dual-Transmitter Engine for 40-Person Linguistic Freedom

To tackle the core pain point of mixed-language commentary, Carlos deployed Richitek’s “dual transmitter + multi-receiver” configuration:

1 RC8860 long-range transmitter — worn by Carlos, covering Spanish and English main commentary.

1 RC2402 secondary transmitter — assigned to local art guide Lucia, handling French commentary for the northern leg.

38 RC2402 receivers — one per guest (the group of 40 minus two guides).

Dual-channel strategy: Carlos locked onto C-12 (channel 1212); Lucia used C-08 (channel 808). Guests simply pressed a button on their receiver to toggle between the two guides, instantly selecting their preferred language.

Itinerary Breakdown: Three Defining Moments

Day 3 (June 10): Bilbao Fine Arts Museum — The “Sound Miracle” in the Underground Gallery

The Bilbao Fine Arts Museum is the most important art殿堂 in northern Spain — and a notorious testing ground for guiding equipment. The underground galleries are a labyrinth of thick stone walls and complex signal interference. In the past, using the legacy RICOM R-10 wired system, guests had to queue for different channel hubs. Over a 4-hour visit, the average wait time per person was 8 minutes.

This time, Carlos stood before a painting by El Greco, wearing the RC8860, while Lucia explained the Basque school in French from a different corner. Forty guests spread across a 100-meter radius — including the most signal-hostile underground hall — heard every word with crystal clarity. One French woman approached Carlos and handed him a handwritten note: “No queue, no missed masterpieces.”

Day 5 (June 12): La Concha Bay, San Sebastián — A Clear Lecture in the Sea Breeze

On day five, the group arrived at the iconic La Concha Bay in the Basque Country. The wind howled off the Atlantic, and the old town’s narrow alleys created a maze of echoes. With conventional equipment, wind noise and reverberation would have swallowed the guide’s voice entirely.

But the RC8860 and RC2402 proved their mettle with exceptional wind-noise rejection and long-distance transmission. Carlos explained the architectural history of the bay from the promenade, while Lucia stood near a Pintxos bar in the old quarter, describing local culinary traditions to the French-speaking members. Even guests wearing sun hats and lagging behind to take photos caught every word about the “tides of the Bay of Biscay.”

Day 7 (June 14): KOR'SIA Dance Company, Madrid — The Silent Guide for Immersive Art

As the tour neared its end, the group entered Madrid to watch a contemporary dance performance by KOR'SIA Compañía. This was an immersive experience — the audience had to follow the dancers as they moved through the space. A traditional “loudspeaker” commentary would have shattered the atmosphere, while paper guides couldn’t keep up with the real-time choreography.

Carlos had everyone wear their RC2402 receivers. He whispered through the RC8860: “Notice the light shifting under the dancer’s feet — it symbolizes the passage of time…” Forty people, wearing lightweight receivers, moved silently through the dim theater, following every cue without missing a single performance detail — and gaining a far deeper artistic interpretation than any ordinary spectator.

“Before Richitek, our 40-person art tour meant 40 different languages competing for 3 channel hubs. Now one transmitter, one channel, all 40 guests hear every brushstroke described simultaneously. In Bilbao and San Sebastián, you gave 40 people 40 private art historians at the same time. That is the meaning of art tourism.”

—— Carlos Ruiz, Operations Director, TourArte Norte

🗺️ Key Takeaways for Tour Operators

Dual-channel strategy for 40+ groups: When the group exceeds 30 people and involves multiple languages, the “1 main transmitter + 1 secondary transmitter” setup is the optimal solution. The lead guide controls the main channel, the co-guide handles the secondary language, and guests switch freely — eliminating queues and congestion entirely.

Penetration power in museums and underground spaces: Art galleries, castles, and churches often feature thick stone walls and complex electromagnetic environments. The RC8860’s stable performance in the Bilbao Fine Arts Museum’s underground hall proves its 100-meter omnidirectional penetration — a must-have for high-end cultural tours.

Ease of use for senior art groups: For retirees aged 60+, equipment must be intuitive. The RC2402 receiver’s one-button channel switching and 2-hour fast charge with 9-hour battery life mean that even the silver-haired generation can enjoy the convenience of technology without any learning curve.

🔮 Epilogue: Repeat Order & Future

The success of this tour led directly to a repeat purchase. At the end of June, TourArte Norte placed an additional order for 1 set (10 units) of RC2402 receivers, preparing for the autumn art festival season in 2026. In October, they will host four more art ensembles — and Richitek has already become the indispensable “41st member” of Carlos’s team.
