In the world of location sound, two fears haunt every mixer: losing the perfect take to RF dropout and wasting precious production time on technical adjustments. What if you could eliminate both concerns simultaneously?
We spoke with Zulhafis Mohmad, a location sound professional known for Narko Integriti (2024), Blood Brothers: Bara Naga (2025) and J Revolusi (2017), who discovered how Deity’s combination of intelligent wireless control and robust internal recording is transforming the way sound departments work – giving them both security and speed.
The Double Challenge: Distance and Time
Every sound mixer faces the same fundamental obstacles. First, there’s the RF challenge:
“My primary audio challenge is RF drop out especially when the actor is far away”
Wireless transmission is inherently vulnerable to distance, obstacles, and interference – factors that intensify during dynamic performances and large sets.
Second, there’s the time pressure. Adjusting transmitter levels traditionally meant physical access to each unit, interrupting workflow and potentially missing critical moments. In fast-paced production environments, these interruptions compound into significant time loss. Deity’s approach tackles both challenges head-on through two complementary technologies: the Sidus Audio app for remote control and the Theos system’s internal recording for bulletproof backup.
Internal Recording That Saves the Day
Let’s talk about the feature that changes everything: internal recording.
“Internal recording is my life saver”
The Theos transmitters record audio internally while simultaneously transmitting wirelessly. When RF signals weaken – whether due to distance, obstacles, or interference – the internal recording continues capturing every word, every breath, every nuance of the performance. “It’s saved me a few times when the actors are far away and the RF signal is lost,” the professional shared.
Think about what this means in practice: Your lead actor delivers an emotionally charged performance at the far end of a massive warehouse set. The wireless signal struggles, but it doesn’t matter. The internal recording has captured everything flawlessly. No need to ask for another take. No need to explain to the director why the audio wasn’t clean. The moment is preserved, perfectly.
Internal recording also proves invaluable for extreme audio situations. “Theos internal recording is super useful for very hot signal such as shouting, screaming and pyro,” the mixer explained. When actors project intensely or work near explosive effects, internal recording captures these challenging dynamics without the complications of real-time monitoring and adjustment.
The Sidus Advantage
While internal recording provides security, the Sidus Audio app delivers unprecedented efficiency. Managing multiple Theos transmitters becomes remarkably simple when you can control everything from your mobile device.
“It is faster and easier to adjust the transmitter input level and timecode setup using the Sidus Audio App,” the professional noted. Instead of navigating through talent, crew, and equipment to physically access each transmitter, adjustments happen in seconds from wherever you’re positioned. This remote control capability transforms your relationship with the gear – you’re orchestrating a system, not managing individual components.
“I like how easy it is to set up the timecode and control all transmitters using Sidus apps.”
The ability to configure multiple units simultaneously means faster call times and more responsive adjustments during takes. When a director calls for level changes or technical modifications, you’re ready immediately.
The real revelation? You rarely need to make those adjustments at all. “I don’t have to ask for one more to adjust the transmitter level,” the mixer explained, “because internal recording” provides the flexibility to work with challenging audio without constant real-time intervention.
Timecode That Never Drifts
Audio reliability extends beyond capturing sound—synchronization matters just as much. The TC-1 timecode generator earned specific praise for its unwavering accuracy. “Consistent timecode, no drift at all,” our sound professional confirmed.
Ask any post-production team about their technical concerns, and timecode drift ranks near the top. Even minor synchronization issues create hours of additional work in post-production. The TC-1 eliminates this concern entirely, providing “zero timecode drift” that the team “really love.”
This reliability isn’t just a technical achievement – it’s peace of mind. When you know your timecode is absolute, you eliminate an entire category of on-set anxiety and post-production headaches.
The Complete Package
What makes the Deity approach particularly effective is how these features work together. Internal recording provides the safety net that lets you work confidently in challenging RF environments. The Sidus app control gives you the speed and flexibility to manage complex setups effortlessly. Rock-solid timecode ensures everything syncs perfectly in post.
Combined with accessible pricing – “The cost of Deity product is affordable compared to other location sound brands” – this technology becomes practical for a wide range of productions, from independent films to larger commercial projects.
Innovation You Can Trust
“I’m satisfied with Deity products and I know Deity will keep improving their products”
This confidence reflects not just satisfaction with current capabilities, but trust in Deity’s commitment to solving real production challenges.
At Deity Microphones, we understand that location sound professionals need two things above all: security and efficiency. The Theos Digital Wireless System’s internal recording ensures you never miss a critical moment, while the Sidus Audio app and TC-1 timecode generator streamline your workflow from call time through post-production.
