LL1545A is a general purpose audio transformer with a variety of connection alternatives. The transformer is
built up from two coils, each with a secondary winding surrounded by shields and two primary windings. This
results in an excellent frequency response.
The LL1935 is a transformer design for DI "Direct Input" applications, matching high impedance guitar pickups to low impedance microphone preamp inputs, but it is recommended for 1:10 microphone input applications as well. Turns ratio: 1 + 1 : 5 + 5.
