Stereo DC Power Amplifier
The new SE-C01 may be a compact component but puts out the kind power you expect from a much larger amplifier. And it does this in the high fidelity tradition, with virtually flat response over the entire audible range and total harmonic distortion of only 0.03%. It's a true DC amplifier that can handle the nuances and power of a full orchestra.
DC Amplifier for Realism in Sound This DC (direct coupled) amplifier was designed without any coupling capacitors. You won't find any in the signal path nor in the feedback loop. Nor will you encounter DC drift and instability, problems often arising from this type of design. They have been controlled by the following design measures: a current-mirror loaded differential first amp stage using thermally balanced dual transistors; a voltage amp stage with purely resistive load and excellent open loop characteristics; and a power amp stage
20 Hz square wave response
which, by utilizing the diode-like behavior between transistor base and emitter, provides accurate thermal compensation over an extremely wide range of temperatures. Other features of special note are the current limiter and the short circuit protection circuit.
Delivers 50 W +50 W continuous Easy-To-Read, Color-Coded power both channels driven into LEOs to Meter Power 8 ohms, 20 Hz to 20 kHz with no These easy-to-read LEOs let you use the full power and dynamism of the SE-C01 without more than 0.03% THO This DC amplifier illustrates that big things can come in small packages. The SE-C01 has ultra compact dimension but delivers 50 watts per channel minimum r.m.s. power into 8 ohms with no more than 0.03% total harmonic distortion from 20Hz to 20,000 Hz. Except in the most "power hungry" installations, it easily handles the dynamics and detail of a full orchestra.

Well Designed "IF" Stage for Sensitive, Low Distortion Reception
Three LEOs, 2 arrow shaped yellow ones and one thin-line red one, replace the usual signal strength or tuning meters you normally see on tuners. This feature provides super easy tuning. When no FM station is being received, all three are lit. When a station is approached, one of the yellow arrows goes out and the other indicates in

In addition, this diecast cabinet provides ef fective shielding against extraneous, undesired electromagnetic waves.

FM/AM Stereo Tuner
This "Concise Component" tuner complements the preamplifier and power amplifier, both in size and performance, because it can reproduce the signals broad casted by the radio station with striking fidelity. Its sensitivity, selectivity, channel separation, signal-to-noise ratio and frequency response are all of high technical standards. The secret is, of course, in Technics' choice of high performance components and advanced design.
