EXCLUSIVE M3 - Power Amplifier by PIONEER (1973)


EXCLUSIVE BY PIONEER M3 / C3


The "soul of audio" combined with the advanced art of high-fidelity electronics is behind the unique concept of the EXCLUSIVE M3 stereo power amplifier by Pioneer. Analyses of both the "dynamic" and the "pulsive" characteristics of audio were studied carefully in the creation of the M3. These include transient response, crossover distortion and many other critical aspects of performance. Such static characteristics as power bandwidth and frequency response were also closely examined. The results are as brilliant as they are daring. To illustrate, consider the problem of providing stability versus the question of assuring wide frequency response and minimum distortion. Pioneer designed an entirely new type of circuit for the M3 to achieve both: it features the reliable circuit design and high-quality parts for stability, yet allows a small amount of negative feedback to be applied to improve frequency response and assure low-distortion performance. 

Sophisticated features like peak-power level meters, a front sub-panel providing access to speaker selector and function of the M3. Individual technical-data sheets giving the exact test information for each unit is packed with every M3 as it leaves the Pioneer factory. The EXLUSIVE M3 is the perfect blend of technology and musicality, the stereo amplifier you can depend on to deliver the "soul of audio" without compromise. As a quality power amplifier for musical reproduction, the M3 has no peer. It offers you RMS 150 watts+150 watts of continuous power (both channels driven at 8 ohms) within critical 20-20,000 Hz frequency range, with both harmonic and intermodulation distortion held to less than 0.1%. There are two large, very precise peak power level meters on the front panel of the M3. The peak transient levels as high as 20dB contained in any audio signal are indicated instantly and acurately. Compared with ordinary VU meters, the power indication range of this peak meter is exceedingly wide: 0.01W to 200W on a logarithmic compression scale, operating from built-in circuits, thus, you can read the power level without changing meter sensitivity.
