Jensen Transformers JT-11SSP-6M 1:5 Microphone Step-Up Transformer

With its Faraday-shielded input transformers, the Jensen Transformers JT-11SSP-6M can eliminate hum and buzz in line-level signals.  Ultra-low DLP (deviation from linear phase) and time-domain distortion are the result of Bessel-tailored high-frequency and extended low-frequency responses.  The internal Faraday shielding ensures unmatched immunity to hum, buzz, and RF interference (high CMRR).

Whereas transformerless inputs suffer “breakthrough” noise in electrically-hostile environments, inputs using these transformers are unaffected. Ultra-sonic “hard digital edge” artifacts are removed from signals by the controlled high-frequency response of the transformers, resulting in a unmatched sonic clarity.  The JT-11SSP-6M is enclosed in a MuMETAL® magnetic shielding can to further reduce hum caused by nearby magnetic fields.

Several turns ratios are offered to optimize noise performance with various input stage designs. Extremely high dynamic range can be delivered, up to 140 dB, in real-world system environments. 

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-11SSP-6M 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-11SSP-6M




  • Ideal for use with low input impedance circuits
  • Wide bandwidth: -3 dB at 0.4 Hz and 220 kHz
  • Recommended for levels up to +19 dBu at 20 Hz
  • Insertion loss only 1.9 dB in 600 Ω to 600 Ω application
  • High common-mode rejection: 110 dB at 60 Hz

This transformer has split primary and secondary windings which can be connected for either 1:2 (150:600 Ω), 1:1 (600:600 Ω), or 2:1 (600:150 Ω) operation. Distortion, although specified for 600 Ω sources, will be further reduced by lower impedances. A 30 dB magnetic shield package is standard..
