ohm
Ohm (symbol Ω) is a unit of electrical resistance named after Georg Ohm.
Ohm or OHM may also refer to:
People
* Georg Ohm (1789–1854), German physicist and namesake of the term ''ohm''
* Germán Ohm (born 1936), Mexican boxer
* Jörg Ohm (1 ...
s, 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 breaker
A circuit breaker is an electrical safety device designed to protect an Electrical network, electrical circuit from damage caused by current in excess of that which the equipment can safely carry (overcurrent). Its basic function is to interr ...

Clipping may refer to:
Words
* Clipping (morphology), the formation of a new word by shortening it, e.g. "ad" from "advertisement"
* Clipping (phonetics), shortening the articulation of a speech sound, usually a vowel
* Clipping (publications ...

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).
