DATA SHEET MT 4 MULTICHANNEL TRANSFORMER MT 4 MULTICHANNEL TRANSFORMER 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 an 8Ω 100 watt input, and 100 watt 70 volt or 100 watt 100 volt output. The recommended load for the 70 volt tap is 50 Ω. The recommended load for the 100 volt tap is 100 Ω. 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 Euroblock 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 the mounting in Figure 4, next page). This makes this ideal for any rack system where high-performance 100 watt, 100 / 70 volt, isolated distribution transformers are required. For 25 volt audio distribution systems, the TF 4 can be used by connecting the 25V loads between its 70V and 100V taps (green and yellow wires). Thermal resistance of the TF 4 is only 1C/W and is lower when mounted in a MT 4 chassis. Other creative combinations are possible. For example, the yellow/green pair can drive 8Ω loads near to the amplifier, with the red/yellow pair being simultaneously used for a 70 V system. Depending on loading of the 70 V system, this arrangement presents an impedance between 4 and 8Ω to the amplifier. TF 4 can be used at power ratings much higher than 100 W, provided that the low-cut frequency is moved up accordingly. Since voltage capability doubles with each octave, power capability quadruples each octave. See the RaneNote "Constant-Voltage Audio Distribution Systems: 25, 70.7 & 100 Volts" available at rane.com.
