[. . . ] DATA SHEET MT 4 MULTICHANNEL TRANSFORMER MULTICHANNEL TRANSFORMER MT 4 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. [. . . ] 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 8 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 8 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.
