The CA-11DI Transformer is a high impedance, made in the USA instrument direct inject transformer. This custom made transformer is heavily based on the ever sought after UTC A-11, without being a direct clone. Our goal was to capture the tone and vibe of the UTC A-11 while only bringing out the necessary taps specific to direct inject use.

In a vintage direct box with a UTC A-11 it was common to see the UTC A-33 20dB magnetic shield used even though the A-11 has fairly good noise rejection due to its twin coil humbucking design. Our CA-11 is potted in a steel can with a cadmium plated lid. We have a unique internal array of mu-foil covering different planes of the transformer. This mu-foil EMI shielding yields an approximate 28dBs of additional hum reduction.

As a unique DI feature, we have brought out multiple secondary taps. Due to physics, this changes the impedance seen by the bass, guitar or whatever is plugged into the primary. When investigating a few homemade, vintage, pro studio direct boxes...we found the 31.5:1 ratio to be used for some absolute blissful magic.

Primary Impedance: 50k ohms
Secondary Impedance: 31.5:1 = 50 ohms, 10:1 = 500 ohms
Instrument impedance into 1k ohms mic preamplifier: 31.5:1 = 1M ohms, 10:1 = 100k ohms
