Jensen Transformers DIN-2LO-11FL User Manual

DUAL LINE OUTPUT MODULE

1:1 BIFILAR WINDINGS

M Distortion 0.035% typ at 20 Hz and +4 dBu output level
M Wide bandwidth: !!!!3 dB at 0.2 Hz and 15 MHz
M Drives 600 SSSS loads to levels up to +21 dBu at 20 Hz
M Excellent time domain performance: DLP 0.3EEEE typ 20 Hz to 20 kHz
M Insertion loss only 1.6 dB when driving 600 SSSS load

This module is designed for high performance line output stages. The 50% nickel
alloy core gives it excellent distortion and level handling at a cost allowing many
applications to enjoy the advantages of an output transformer. Driving signals
should be free of DC and source impedance kept as low as possible.
