OT-600

Output Autoformer

Basic Description

The OT-600 is a heavy-duty step-up autoformer accessory that adapts any power amplifier output with a maximum voltage of approximately 40 to 50 volts to drive a 70-volt distributed line with up to 600 watts. Three voltage taps let you choose the one most appropriate for the amplifier. The OT-600 can also be used to drive a 100-volt line when used with an amplifier with a maximum output level of 55 to 70 volts.

Conversely, the OT-600 can be used as a high-power speaker transformer, driving loudspeakers with up to 600 watts from a 70-volt distributed line.

The OT-600 autoformer is compatible with any amplifier rated at approximately 350 to 650 watts at 4 ohms. It has built-on brackets for convenient mounting on a panel or in an equipment rack.
