General Description

The MT 4 four-channel distribution transformer is packaged in a space saving 1U, 19-inch rack-mount tray. The fully isolated, high performance toroid transformers provide flat frequency response within 1 dB from 40 Hz to 20 kHz. Each transformer is designed for 8 ohm 100 watt input, and 100 watt 70 volt or 100 watt 100 volt output. The recommended load for the 70 volt tap is 50 ohms. The recommended load for the 100 volt tap is 100 ohms. Convenient Euroblock connectors are provided on the rear of the chassis.

The MT 4 comes ready to use with four mounted transformers and strain-relief Euro connectors. The tray with Euro connectors (model KT 4) and individual transformers with mounting hardware (model TF 4) are available separately, allowing the installer to build a tray with just the number of channels required. (see photo below).

While the MT 4 was designed for use with the Rane MA 4 amplifier, it also works with any other amplifier by just ordering the tray and number of transformers needed. This combination works in any application where high performance 100 watt, 100 / 70 volt, isolated distribution transformers are required.
