Nikko TRM-800

Nikko TRM-800 is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Nikko TRM-800 rather than just read about it. In short: The TRM-800 was a high-end solid state integrated stereo amplifier made in Japan, using NEC power transistors, by Nikko. It was the top-of-the-line model in the Nikko amplifier range of TRM's series; housed in a wooden walnut-finished cabinet and a brushed aluminum front panel, was introduced in 1975 the same year as the Marantz 2235.

Key takeaways

Nikko TRM-800 belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Nikko TRM-800 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Nikko TRM-800 from memory before moving on to harder problems.

Reference excerpt

The TRM-800 was a high-end solid state integrated stereo amplifier made in Japan, using NEC power transistors, by Nikko. It was the top-of-the-line model in the Nikko amplifier range of TRM's series; housed in a wooden walnut-finished cabinet and a brushed aluminum front panel, was introduced in 1975 the same year as the Marantz 2235. It was a two-channel amp; however, it had three sets of speaker connections; those powered selected by buttons. At 8 ohms, the amp could put out 65 Watts per channel RMS (90 Watts per channel RMS at 4 ohms), delivering superb high fidelity sound with exceptional tone quality. Unlike many amps of this time, however, the TRM-800 was stable at lower impedances than 8 ohms; down to 4 ohms. The TRM-800's frequency response ranges 10Hz to 40.000 Hz ±1 dB with T.H.D. less than 0.1% at rated output. Its preamplifier and main amplifier were separable for multi-channel amplifier systems. The amp has internal circuit breakers which prevent it from clipping or overheating. Its power consumption is 250 watts (according to label). For equalization it has only a bass and a treble knob; however the frequency of these are selectable; between 250 and 500 Hertz for the bass, and between 2.5 and 5 kHz for the treble. It also has a high, low, and a subsonic filter. There are two phono stages; phono 2 is provided with impedance matching selection, for using different types of cartridges (MC/MM).

Worked examples

Example 1 — a first encounter with Nikko TRM-800

Start with the simplest possible case. Write down what Nikko TRM-800 claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Nikko TRM-800 before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Nikko TRM-800 ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Nikko TRM-800

In research: Nikko TRM-800 appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Nikko TRM-800 in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Nikko TRM-800 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Audio amplifiers, so understanding it makes those chapters shorter.
In everyday life: Look for Nikko TRM-800 outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
