DATA SHEET
General Description
°e MT 4 four-channel distribution transformer is packaged in
a space saving 1U, 19-inch rack-mount tray. °e fully isolated,
high-performance toroid transformers provide flat frequency re-
sponse 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. °e recommended load for the 70 volt tap
is 50 Ω. °e recommended load for the 100 volt tap is 100 Ω.
Convenient Euroblock connectors are provided on the rear of the
chassis.
°e MT 4 comes ready-to-use with four mounted transform-
ers and strain-relief Euro connectors. °e tray with Euroblock
connectors (model KT 4) and individual transformers with
mounting hardware (model TF 4) are available separately, allow-
ing the installer to build a tray with just the number of channels
required. (see the mounting in Figure 4, next page). °is 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). °ermal 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 capabil-
ity quadruples each octave. See the RaneNote "
