O-Mini P48 Microphone
O-Mini P48 Microphone
The O-Mini P48 is a high-sensitivity, miniature omnidirectional electret microphone that features a natural frequency response and captures usable ultrasonic frequencies up to 90KHz (-10dB at 30kHz). These microphones are a good choice for recording subtle elements and active natural environments yet are also robust enough to be used on louder sources such as guitar cabinets and as drum overheads.
Available in: Stereo-Matched & Quad-Matched sets
The O-Mini P48 requires Phantom Power (24v-48v) to operate and is built using premium components from Neutrik, Mogami and Primo.
Designed and hand-built in Michigan’s Upper Peninsula.
Tech Specs:
Frequency Response: 20 Hz - 30,000 Hz (-10dB)
Sensitivity: -28dBv with 1KHz tone at 94dBA (±2 dB).
Matching: Individual microphones in a set are matched within 1dB at 1Khz, with full-spectrum matching prioritized over 1kHz matching. Between unmatched sets, there can be a ±2 dB variance.
Self-Noise: ~20dBA
Max SPL: 126dB with <5% THD; 120dB with <1% THD
Operating Voltage: 24-48v Phantom
Microphone Diameter: 7mm (See below for Wind Protection Recommendations)
Cable Length: 5’
Output: 100 Ohm, Balanced XLR
Sound Examples:
All examples come straight off the recorder, with no processing done beyond fade in/outs and potentially a coarse gain adjustment on the whole file.
Testimonials
“I've used several O-Mini P48 and PIP mics over the past year and they have quickly earned their place in my regular expedition kit. These mics have survived many humid nights in rainforests without skipping a beat. The self noise is low, they don't clip easily and they reach high in the frequency spectrum. I only hope Chris can ramp up production to keep up with demand.”

Recommended Wind Protection:
The O-Mini’s exterior diameter is 7mm wide (Click to go to website)
Low Wind: Twin Windbubble Lav Size 2
Moderate Wind: Medium Windbubble Pro
Moderate to Slightly Heavier Wind: Medium Windbubble Pro Extremes
For Heavy Wind, I would recommend using some sort of blimp system to create a more robust air barrier around the microphone.
FAQ

Presently, International orders (outside the USA) are limited to $400 USD per individual order. EU customers must pay their own VAT.
The particulars of international orders are something I am still learning. I am currently using a service that will do all of the requisite customs work and then cheaply send packages worldwide, but they restrict their services to orders no more than $400 USD. For the time being, this lack of flexibility is one sacrifice I am making.
I apologize for the inconvenience. From what I can tell, a single person could make multiple discrete international orders and be fine. While doubling up on shipping costs is less than ideal, ordering twice through this service is still cheaper than the other options I have found.

The reduce the complexity of shipping logistics, the webstore is currently automated to use USPS.
If you need something faster than Priority Mail speed or prefer a different carrier (IE: Fedex or UPS), please either use the contact form here or email me at info (at) chrisatrevino.com and I can create a custom quote for you.
I appreciate your patience with this process. As I scale and learn more of the logistics end of things, I hope to expand the automated shipping service providers.

The current O-Mini P48 version is not compatible with 1/8”/3.5mm inputs.
The O-Mini P48 requires a regulated voltage above what the plug-in power (PiP) on most consumer devices can provide.
