APPLICATION Microphone input transformer for matching a 30/50 ohm microphone to a 600 ohm input or desk with any input impedance greater than 600 ohms. Will increase the  level by approximately 12 dB.  For reduction of most kinds of noise caused when equipments are connected. For helping to ensure Electromagnetic Compatibility (EMC) standards compliance. May be used for balanced to unbalanced conversion and vice versa.
FEATURES Mumetal core for minimal harmonic distortion. Internal electrostatic shields for maximum common mode noise rejection at high frequencies. Multiple interleaved windings ensure low leakage inductance for excellent high frequency response. Mumetal can for magnetic shielding. 
RATIO 1:4.5
MAXIMUM INPUT LEVEL 0.5 % THD at 20 Hz (40 ohm source) -6 dBu
DISTORTION at 50 Hz (40 ohm source) 0.05 % at -6 dBu
INSERTION LOSS 30ohm source 600 ohm load 0.75 dBu
INPUT/OUTPUT BALANCE >60 dB
FREQUENCY RESPONSE 40 ohm source 600 ohm load +/- 0.25 dB 10Hz to 60 kHz
