Stereo Reverberation Amplifier (1980-82)
The Pioneer SR-303 is an all electronic reverberation amplifier which incorporates an audio-use delay element known as a bucket brigade device (BBD).
Unlike conventional mechanical reverberation amplifiers this particular unit is not in the least affected by external vibration or fluctuations in the reverberation effect.
Furthermore, the delay element features a C Mos IC semiconductor which contributes greatly to yielding such impressive characteristics as a high signal to noise ratio of 90dB and a low total harmonic distortion.
Input sensitivity: 150mV
Frequency response: 5Hz to 70kHz
Total harmonic distortion: less than 0.05%
Signal to noise ratio: 90dB
Reverberation time: 0-3s (effect 1), 25-100m/s (effect 2)
Output level: 150mV
Semiconductors: 8 x IC, 1 x FET, 14 x transistors, 16 x diodes
Dimensions: 420 x 99 x 336mm
