LMI8 is a large core transformer that features a split bobbin platform presenting 8.5K(4.25K:4.25K):300R(200R:100R). This transformer is a heavy, large and gorgeous sounding offering that is perfectly suited for the U47 microphone. Wired as a 8.5K:200R transformer it presents a 6.5:1 ratio using large laminations featuring a special brew of metallurgy and winding techniques that present excellent signal handling quality, intense musicality and lush tonal character. Due to the platform utilized for this design, the amount of laminations available are larger than a typical microphone output transformer (nearly ¾” or 17.8mm of actual laminations) and give the end user the advantage of higher signal handling quality and advantageous low frequency response that does not sound artificial. This transformer is recommended for microphones with larger bodies such as U47 style bodies, the GT2B and the SYT5. As standard, this design features split primaries and secondaries, which makes it compatible with other designs such as FET microphone circuits, tube microphones using cathode follower circuits, microphone preamps (solid state and DC coupled tube). Possible alternative ratios include 3.76:1 (4.25K:300R), 4.6:1 (4.25K:200R), 6.5:1 (4.25K:100R), 9.2:1 (8.5K:100R), 5.3:1 (8.5K:300R).
