Jensen Transformers DIN-PB Install Guide

LINE INPUT/OUTPUT TRANSFORMER

1:1 SPLIT WINDING "REPEAT COIL"

M Ideal for patch bay applications
M Wide bandwidth: !!!!3 dB at 0.4 Hz and 200 kHz
M Recommended for levels up to +21 dBu at 20 Hz
M Voltage loss only 1.9 dB in 600 SSSS to 600 SSSS application
M High common-mode rejection: 125 dB at 60 Hz

This transformer has split primary and secondary windings which can be
connected for either 1:2 (150:600 S), 1:1 (600:600 S), or 2:1 (600:150 S)
operation. Distortion, although specified for 600 S sources, will be further
reduced by lower impedances.
