Made in the USA
CineMag CM-DBXPC Direct Box Transformer

CineMag CM-DBXPC 12:1 "Direct Box" Transformer

CineMag CM-DBXPC "Direct Box" Transformers are ideal in applications like musical instrument feeds, where they can solve hum and buzz problems.  Housed in a Mu-metal can, 30 dB of magnetic shielding is provided.  It exhibits excellent bandwidth, very low phase shift, very good common mode rejection ratio (CMRR), and very good distortion characteristics

The CM-DBXPC can be driven by sources ranging from low to moderately high impedance.  As with all CineMag transformers, the internal foil shields between windings are spot welded to the connecting wires to maximize long term reliability.

Offered here in a PC Board mounting style, it is also available with wire leads by special order in the cart below.

Here are some key specs:

  • Converts unbalanced line levels to balanced mic level
  • Feed long cables without high frequency loss problems
  • Helps to eliminate hum problems in musical instrument hookups
  • Very Good CMRR: 105 dB at 60 Hz, 89 dB at 1 kHz
  • Very wide bandwidth and low phase shift
  • PC mount and lead packages

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 CM-DBXPC is made in the USA, and is backed by Cable Solutions' three-year warranty  Please ask for details.

About CineMag


To manufacture the very best audio magnetic components in the world!


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".


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. In order to ensure the very best-performing products for our customers, every device that we manufacture must pass a computerized test.  For this reason, all manufacturing is done in our own facility in Simi Valley California.

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.
