Jensen Transformers JT-DB-EPC 12:1 "Direct Box" Transformer
The Jensen Transformers
JT-DB-EPC ISO-MAX 12:1 "Direct Box" Transformer features a double Faraday shield and a 30 dB magnetic shield.
These Jensen Direct Box Transformers are the ideal choice for coupling guitar pickups, musical instrument and other line level outputs to low impedance microphone inputs. They also give excellent results when used as an output transformer for Tube type condenser microphones. Direct Box transformers provides ground isolation and allow long cable runs from high impedance sources without excessive bandwidth loss.
It may also be worth mentioning that the JT-DB-EPC is a direct replacement for the CT283 transformer, as used in the Rode Classic II microphone.
Here are some specs:
Impedance ratio: 200k : 1.5k
Turns ratio: 12:1
Maximum 20 Hz input: +22dBu
THD @ 20 Hz: 0.036 %
THD @ 1 kHz: < 0.001 %
20 Hz re:1 kHz: -0.08 dB
20 kHz re:1 kHz: -0.07 dB
With inferior products coming from all over the world, we think it is a genuine treasure to find a company like Jensen Transformers, actually designing and manufacturing some of the finest products in the world, right here in the USA, and we are proud to be able to offer their products. The JT-DB-EPC is made in the USA, is backed by the manufacturer's comprehensive one-year warranty, and has a remarkable 20-year warranty on the transformer device itself.
Jensen Transformers' Description
Jensen Transformers JT-DB-EPC
12:1 "DIRECT BOX" TRANSFORMER
DUAL FARADAY SHIELDS FOR HIGH ISOLATION
Converts unbalanced line levels to balanced mic level output
Stops "hum and buzz" problems in musical instrument hook-ups
Allows use of long cables without high frequency loss
High common-mode rejection: 100 dB at 60 Hz
Excellent frequency response and time domain performance
When loaded by the 1 kΩ input impedance typical of mic preamplifiers, this transformer has a 140 kΩ input impedance, making it ideal for high impedance sources. It can be used with or without an active buffer as a "direct box" for electric guitars or synthesizers. A 30 dB magnetic shield package is standard.
This picture shows the bottom of the  transformer.
The JT-DB-EPC is packaged in a small cardboard box as shown here, and we include a printed copy of the data sheet.
