CineMag CMLI-15BPC Line Input Transformer

1:1 Winding Ratio, Mu-metal Magnetic Shielding, PC Board Mount

The CMLI-15BPC line audio input transformer is often chosen for use in wideband input amplifiers. This transformer demonstrates good bandwidth, common more rejection ratio (CMRR), and distortion qualities. The transformer is encased in a mu-metal can, providing 30 dB of magnetic shielding.

All the wires connecting the internal foil shields between windings are spot welded for maximum long term reliability, as is done with all CineMag transformers.

The CMLI-15BPC offered here has a PC board mounting style, but it is also available with wire leads as CMLI-15B, which, at the time of this writing, is available as a special-order option in the cart below.

Here are some key specs:

Use to balance unbalanced inputs
High input impedance: 18K? with 15K? load
Good bandwidth (- 3 dB at 72 kHz, 15K? load)
Excellent CMRR: 105 dB at 60 Hz
Maximum input level +20 dBu at 20 Hz

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 CMLI-15BPC 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.
