Dizengoff Audio D4 Mic Microphone Preamp. The Dizengoff D4 is a tribute to a rare and much loved British tube console from the 1960s. The original circuit was designed by the R ecording E ngineering D evelopment D epartment as a replacement for the Siemens V72S amp cards used in an earlier British console. It featured three gain settings (+36, +40, and +46), and a fine trim knob that allowed the user to trim gain by a few dB.
The D4 has expanded that range from +20 up to +60 using a 12 step rotary attenuator. Like the original design, the D4 trim control allows the user to fine tune the gain by 2-4dB depending upon the gain switch setting. The sound is huge and open heard on albums recorded by The Beatles , Pink Floyd , and The Zombies between 1964 and 1968. It has incredible detail, and the kind of wonderful coloration that only an EF86 pentode can deliver.
Its often considered to be the sound of John Lennons Revolution, which used two console channels in series to achieve an overdriven sound. Signal path transformers are custom wound right here in Chicago. Theyre based on the transformers used in the original, but they take advantage of modern materials.The input transformer is a hi-nickel (80% nickel content) and the output transformer is a lo-nickel (50% nickel) for excellent fidelity. The power supply is internal.
Its built around a Japanese Nippo Steel R-core power transformer. It has extremely high efficiency and low noise compared with traditional E-I core transformers and plays a significant part in achieving the D4s low noise performance.12 position stepped gain control, 20-60dB. Trim control, for fine adjustment of gain. THD+N at 1Khz: 1%, +4dBU, 10-24kHz bandwidth. S/N -90dBA at maximum (+60dB) gain, 10-24kHz bandwidth. We are Dizengoff Audio, home of the new Chicago sound.
