OT-4240/OT-4480/OT-4960: Output Transformer Units

Model: OT-4240 / OT-4480 / OT-49 
Manufacturer: INTER-M - KOREA

The OT-4240/4480/4960 are 60, 120 or 240 watt high impedance transformers. They provide a professional way to install transformers in an equipment rack. The units transform the 4Ω output of any power amplifier to a 70V or 100V level for use with high impedance speakers (distributed systems).The OT-4240/4480/4960 are 60, 120 or 240 watt high impedance transformers.
