A
practically-prieced, medium-power solid state stereo amplifier with wide power
bandwidth and frequency response.
This
handsomely styled unit from Pioneer is perfect for the serious stereo
enthusiast who is building his system within a stipulated budget. At a very
practical price, the SA-600 provides a
host of imortant features and a lot of professional performance that will do
musical wonders for any home stereo system. Its circuits use only long-life,
low-noise silicon transistors, and thus the frequency response and
signal-to-noise ratio are superb. The unit is also very versatile, in keeping
with the Pioneer audio philosophy of giving the most for the consumer's money.
You may use up to two tape decks or two speaker systems with the SA-600, and
you may also adapt the unit for multi-amp use.
More for yo
our money? The SA-600 is probably the finest value in a medium-power amplifier
now available. Take a listen.
Direct
Coupling Preamplifer Section
The
equalizer circuit of the SA-600 uses two-stage direct-coupling negative
feedback circuits with low-noise silicon transistors. Use of these circuits
means that the amplifier delivers an extra-wide dynamic sound range. Then the
tone control section of the SA-600 employs low-noise silicon transistors. You
may increase or decrease the audio signal delivered to the amplifier step by
step with each click-stop. Rate of attenuation is indicated on the front panel.
Finally, harmonic distortion with this amplifier is negligibly small, while
signal-to-noise ratio is excellent and stable.
Stable Power
Amplifier Section
The power
amplifier of the SA-600 is quasi-complementary design, single-ended push-pull
circuit that insures virtually distortionless sound reproduction and a wide
frequency response. Music power output of this unit is big compared to
similarly-priced units, upp to 100 watts at 4 ohms, IHF. With both channels
driven, continuous power output is 19 watts each channel at 8 ohms. And in the
critical 20 to 20,000 Hz frequency range, both channels driven, the unit
delivers 13 watts plus 13 watts at 8 ohms with THD measured less than 0,5%.
Two Sets of
Input Jacks and Output Terminals
The SA-600
is equipped with two pairs of Tape, Phono and Aux input terminals to permit
ease of tape-to-tape duplicating and to allow comparison of different phono
cartridges. You may use any two tape decks - open reel, cassette, 8-track
cartridge, etc. - connected simultaneously with the amplifier. Additionally,
you may use one microphone connected through the Mic input jack located on the
front panel. The SA-600 is equipped to handle two sets of speaker systems which
may be played simultaneously if desired to enable you to compare the tonal
qualites of each system.
Pre/Main Amp
Separator Switch
The
preamplifier and main amplifier sections of the SA-600 can be used separately
by using the pre/main switch. By adding an electronic crossover network
(Pioneer model SF-700 or SF-500) and one or more power amplifiers, you may also
adapt your music system to a multi-amplifier stereo system.
Other
Features
The SA-600
has both high and low filters to eliminate unnecessary noises without tonal
deterioration. The unit is also equipped with a loudness contour switch and
mode switch.
