In a recent discussion within the DJ community, a question arose regarding 900 MHz microphones and their relevance in today’s audio landscape. The speaker reminisced about older microphone models, including a Gemini and an SHT brand, both operating on 900 MHz. While 15 to 20 years ago, these microphones were more common, their use has diminished due to several factors. The speaker explained that the 900 MHz band offers limited bandwidth—around 10 MHz—making it less viable for multiple channels compared to other frequency ranges. Additionally, the 900 MHz band is classified as an ISM (Industrial, Scientific, and Medical) band, meaning it is crowded with various license-free devices, further complicating its use for audio transmission.

Despite the challenges, the speaker clarified that 900 MHz microphones are not entirely obsolete; they can still serve as a functional tool in specific scenarios, especially in crowded markets where finding frequency space is challenging. The speaker also highlighted that while 900 MHz may not be the first choice, it remains a useful option for certain applications.

Furthermore, the conversation shifted to the advancements in wireless microphone technology, specifically mentioning new YMAS systems that allow for significantly wider bandwidths, albeit at a high cost. The speaker emphasized that comparing high-end 900 MHz systems to older, less reliable models underscores the evolution of audio equipment. The discussion concluded with a pivot toward visual content, signaling a transition to a new topic.

Highlights
🎤 Historical Context: The discussion began with a reflection on older 900 MHz microphones, such as those from Gemini and SHT, which were popular in the past but are now considered outdated.
📉 Limited Bandwidth: The 900 MHz range is constrained to approximately 10 MHz, limiting the number of channels that can effectively operate within it.
🏙️ ISM Band Complexity: As part of the ISM bands, the 900 MHz frequency range is crowded with various devices, making it less reliable for audio transmission.
⚖️ Trade-offs in Frequency Use: While 900 MHz may not be a primary choice, it can be a practical solution in densely populated markets where frequency space is limited.
💰 Emerging Technologies: Newer systems, like YMAS, are emerging with wider bandwidth capabilities, although they come with a steep price tag.
🍏 Quality Variation: There is a significant difference in quality between high-end 900 MHz systems and older, budget models, highlighting the importance of investing in reliable equipment.
📸 Transition to Visuals: The conversation shifted from audio technology to visual content, indicating a broader discussion about multimedia in the DJ industry.
