                  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.

                  • Distortion 0.035% typ at 20 Hz and +4 dBu output level
                  • Wide bandwidth: !3 dB at 0.2 Hz and 15 MHz
                  • Drives 600 S loads to levels up to +21 dBu at 20 Hz
                  • Excellent time domain pe

                • Jensen DIN-LO-11DM 600 to 600 1:1 Line Output Module

                  Jensen DIN-LO-11DM 600 to 600 1:1 Line Output Module

                  This module is designed for very high performance line output stages. Specially processed 80% nickel core alloy is used for lowest possible harmonic distortion of high level low frequency signals. For best performance, driving signals should be free of DC and source impedance kept as low as possible.

                  • Distortion 0.004% typ at 20 Hz and +4 dBu output level
                  • Wide bandwidth: !3 dB at 0.10 Hz and 15 MHz
                  • Drives 600 S loads to levels up to +22 dBu at 20 Hz
                  • Excellent time domain performance: DLP 0.3E typ 20

                • Jensen JT-11SSP-6M 600 Ohm Line Isolation

                  Jensen JT-11SSP-6M 600 Ohm Line Isolation

                  This transformer has split primary and secondary windings which can beconnected 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 reducedby lower impedances. A 30 dB magnetic shield package is standard.

                  • Ideal for use with low input impedance circuits
                    Wide bandwidth: !3 dB at 0.4 Hz and 220 kHz
                    Recommended for levels up to +19 dBu at 20 Hz
                    Insertion loss only 1.9 dB in 600 S to 600 S application
                    High common-mode
