LL1544A is a line input / general purpose audio transformer which can be used in many different applications ranging from bridging input to microphone input applications. The transformer is built up from two threesection coils with interleaved Faraday shields. The core is a two-component amorphous strip core. This core type combines a high sensitivity for very low signal levels with excellent high-level capabilities. In addition, as this type of core does not store energy (unlike conventional
mu-metal cores), at low frequencies phase response is excellent and resonance with a series capacitor is practically eliminated.
The LL1544A replaces previous types LL1544 and LL1554.
