CineMag CMMI-3.5APC Microphone Input Transformer
1:3.5 Turns Ratio, Mu-metal Magnetic Shielding, PC Board Mount
CineMag CMMI-3.5APC Mic Input Transformer
CineMag CMMI-3.5APC Microphone Input Transformers are ideal for OEM products. The winding turns ratio is 1:3.5. They feature very good bandwidth, common mode rejection ratio (CMMR), and distortion specs. A mu-metal can provides 30 dB of magnetic shielding. Mounting is via PC board pins.
To ensure long-term stability and CMMR, the internal Faraday shield foils are spot welded.
Here are some key specs:
- Economical design for OEM applications
- Good bandwidth (+ 1/4 dB at 20 kHz)
- Very good CMRR: 110 dB at 60 Hz
- Low profile p.c. mount package
With so many once-great American manufacturers selling their brand names and/or moving their manufacturing outside of the USA, we are particularly thankful that CineMag remains dedicated to designing and manufacturing some of the finest products in the world, right here in the USA, and it is an honor to represent their products. The CMMI-3.5APC is made in the USA, and is backed by Cable Solutions' three-year warranty Please ask for details.
About CineMag
Mission
To manufacture the very best audio magnetic components in the world!
History
The company story goes goes back to Edward Reichenbach in the 1940's, where his experience included the design of many audio transformers for Altec Lansing. Following that, Ed formed his own company, making audio transformers, inductors, and power transformers for use in professional audio gear. He eventually formed Reichenbach Engineering, where the transformers he designed became ubiquitous standards in the pro audio industry. CineMag was formed as a part of Reichenbach Engineering in 1979, manage by Ed's son, Tom. The CineMag name reflects the company's early focus upon magnetic tapes heads for cinema; "Cinema Magnetics" was concatenated to "CineMag".
Commitment
In order to obtain the very best results in an audio design, attention to detail is imperative. Even the slightest deviation from the ideal manufacturing process can result in product that does not meet our high standards. For this reason, all manufacturing is done in our own facility in Simi Valley California.
In order to ensure the very best-performing products for our customers, every device that we manufacture must pass a computerized test.
CineMag has distinguished itself as the leader in audio magnetics through dedication to excellence in manufacturing and service. CineMag offers a broad range of audio transformers and inductors, and research and development is still ongoing. Only by keeping all manufacturing in-house are we able to maintain the highest possible standards of quality.
