MIT Output Terminator Series Two A Look at Energy, Efficiency, & Audio Cables
Energy is the ability to perform work; energy is expended when work is done. Power is the rate at which work
is performed. Power is always related to time.
MIT Terminator Technology, Energy & Efficiency
Typical cables store very little energy and have problems
transporting the Energy Component to the load efficiently.
The new MIT Output Terminator Series Two technology stores
more energy and is able to store this energy in a more stable,
noise-free manner than was possible in the 330/750 Series. In
addition, these new Output Terminators transport the Energy
Component to the load with even greater Efficiency.
The music signal, in its electric form, is comprised of voltages and currents. (Each frequency is composed of its
own voltage and current.) On their way between
source and load, these two elements are stored for a
short time in the cable as energy. These stored elements
combined form a final component that MIT calls the
Energy Component. (This Energy Component is to elec tricity what gasoline is to an automobile engine.) The
Energy Component is ultimately released and transported to the load as Transportable Power. In transportation, how well the cable maintains phase relationships between voltage and current MIT quantifies as
Efficiency.

Brief Tutorial on Joules, Watts, & Horsepower
1
(1) Joules. Electrical energy is defined in joules: 1 joule
equals 1 watt in 1 second. (2) Watts. This energy is
released over a specific period of time as power, quantified in watts. In a speaker cable, for instance, this energy will ultimately be converted to power at the speaker
in a stereo system. The speaker draws energy from the
cable (as well as the amplifier’s power supply) and converts it to power. An important concept concerning
power in an electrical circuit is that before true power,
or watts, can exist, some type of energy change or conversion must take place. In other words, electrical energy must be changed or converted into some other form
of energy - heat or mechanical energy - before there
can be power or watts. (3) Horsepower. When James
Watt first began to try to market steam engines, he
needed a way to compare them to the horses they
were to replace. After conducting experiments, Watt
found that the average horse could work at a rate of
550 foot-pounds per second This became the basic
horsepower measurement. Horsepower can also be
expressed in the basic electrical unit for power, which is
the watt: 1 horsepower equals 746 watts.

Figure 1A. (above) Energy Component, Typical Inexpensive Audio Cable. This
is a typical cable sold in audio stores worldwide. Note how little Energy
Component this type of cable stores (rising to 1.3 joules). Also note the non-linear
manner in which the cable stores this Energy Component (dropping down to
about 0.2 joule at 20 hertz). Figure 1B. (below) Efficiency, Typical Inexpensive
Audio Cable. Note how inefficiently the cable transports the small amount of
energy it has stored (reaching the 50% line, -3 dbw down point, at about 2.5 KHz).

Figure 2A. (above) Energy Component, High End Audio Cable. This is a highquality high end cable sold throughout the 1980s. Although this cable stores a
little more Energy Component than the cable in Figure 1A, and stores it a little
more linearly (dropping only down to 0.6 joule at 20 Hz), it transports its Energy
Component more efficiently. As you will see, however, this still leaves much to
be desired see.

Or as Mr. Watt also taught us, 1 HP
equals 746 watts, so MIT’s MH-770
Reference CVTerminator transports
2.001 HP in the same period of time
“just cable” transports .002HP.
Thank you, Mr. Watt!

Remember, electrical energy must be converted into another form of energy
before it can be call “watts.” If 1 joule equals 1 watt in 1 Second , then 1492
joules would develop 1492 watts in 1 second!

A Note on the Measurements
In the calculation of the energy and power figures used in this
paper, voltage and current must be entered into our simulator. When normal line levels are used, the energy actually
stored is quite small - on the order of microjoules. This results in
plots with axis scales in scientific notations that re difficult to
read and understand.
In deference to humans accustomed to dealing with “normal” number, therefore, we increased the voltage and current to bring the energy and power up to comprehensible levels. While the levels were increased greatly, the same line levels were used for all products, and no matter what the levels,
the magnitude of difference between all products remains the
same.
