1:1 or 1:2 Ratio, Quadfilar Windings, 50% Nickel + 50% Steel Laminations, PC Board Mount

Made in the USA
CineMag JR-123-FLPC Lline Output Transformer

CineMag CMOQ-4LPC 12:1 Direct Box Transformer

CineMag CMOQ-4LPC line audio output transformers' Quadfilar windings ensure good coupling and excellent bandwidth and with their 1:1:1:1 turns ratio, both 1:1 and 1:2 configurations are possible.  50% Nickel + 50% Steel laminations ensure superior sonic performance. These transformers can be driven with source impedances as high as 600 Ohms.

Shown here with a PC board mounting configuration, it is also available with lead wires.

It may also be worth mentioning some heritage here.  CineMag is the progenitor of Jensen Transformers, and with that context in mind, this transformer could be considered to be an upgrade for JT-123-FLPCH, for PC board layouts that can accommodate its 12-pin footprint.

Here are some key specs:

  • Excellent bandwidth: -0.1 dB at 200 kHz (Rs = 50Ω 80% Nickel (“HiNi”) laminations)
  • Distortion ≤ 0.07% typ. at 20 Hz, Rs = 150Ω
  • +15 dBm at 20 Hz, 1% THD+N Rs ≤ 150Ω
  • Phase Shift -3.52° at 20 kHz, Rs = 150Ω
  • Excellent coupling

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 CMOQ-4LPC is made in the USA, and is backed by the manufacturer's comprehensive three-year warranty.

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. 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.
