NTL 1 Linietransformator 1:1
Professional studio transformer 1:1 for PCB mount, fully shielded.
Applications: line input
General Description
NTL1 is a line transformer intended to balance amplifier outputs for line driving up to
+24 dBm.
NTM1
and NTM4 are input transformers intended to match mic-level lines to
active micinput amplifiers. Existing center tap for phantom powering.
All types are designed for direct PCB mounting and are featuring electrostatic shielding
between windings and heavy Mu-metal shielding/housing.
