Pioneer - SA-7300 - Amplificatore integrato a stato solido
6 EUR
DESCRIPTION:\r
\r
Hybrid IC circuitry employing dual positive and negative power supplies is incorporated in the power amplifier section of the SA-7300. All stages are directly coupled in the OCL circuit design to provide plenty of power at minimized distortion. Output is 35W + 35W in the range of 20Hz-20kHz at 8 ohms with both channels driven and 0.3% harmonic distortion.\r
\r
The equalizer amplifier also utilizes a dual positive and negative power supply and IC circuitry to assure RIAA deviation within +0.3dB, while a maximum input of up to 200mV (at 1 kHz) can be easily handled (at 0.1 % harmonic distortion).\r
\r
Both relay and electronic circuitry combine to safeguard valuable transistors and speakers in event of malfunction. This special protector circuit also performs a muting function to prevent annoying surge noise when the POWER switch is operated.\r
\r
Advanced CR type tone controls and 2-stage direct coupled amplifier provide highly effective control operation. Regardless of the tone control settings, a flat frequency response can always be obtained by employing the TONE switch. This is convenient for checking cartridge and speaker tone, and evaluating listening room characteristics.\r
\r
The recording and playback jacks of the SA-7300 are provided for two tape decks, in addition to separate Tape Monitor switches. Extremely convenient tape duplication and editing can be performed if two tape decks are available.\r
\r
The clean uncluttered front panel layout avoids a confusing array of unnecessary controls and switches. Modern serene styling is combined with one-glance operational ease.\r
