Pioneer SA-9500


Pioneer believes in music. And if you do, too, you'll find a faithful friend in the new SA-9500; one of the most musically minded pre/main stereo amplifiers we've engineered.

It combines massive stereo output power with a delicacy of transparency; a rare blend in these days of lots of power at any cost.

In other words, we haven't simply beefed up the power section at the expense of the tonal quality, frequency response or other aspects so important to the sound of a high fidelity component.

The Pioneer SA-9500 does deliver an unusually large continuous power output of 80 watts per channel, min RMS at 8 ohms from 20 Hertz to 20,000 Hertz with no more than 0.1% total harmonic distortion, but it also ensures that even when operated at low volumes the performance retains a crisp, sparkling clarity.

The dynamic response and reliability of the SA-9500 are matched with a flexibility of use you'll rarely find in this price range. Tone control versatility, for instance: both the bass and treble sections have 3-position turnover selection and there's a tone on/off switch for "flat" response at a touch.

The 2-step high and low filters, the extra convenient tape duplicating switching system, multiple input source selection, 2-system speaker switching and much more mean first-class handling.

We believe in music. And we're sure that if you do, too, you'll believe in the all-new SA-9500.

I bought the SA-9500 in 1977 (I was 17 at the time). I've used is most of my life now and have had several other amps and have always gone back to the SA-9500. Maybe it is that good, or maybe it has become the standard that my ears judge all others by.



re: SA-9500 II

Wouldn't it be a simpler connection for an equalizer to patch it in through the tape monitor input?

pioneer amp and graphic equalizer

Hello there , can anybody let me know if i can use the Pioneer graphic equalizer SG 550 with the Pioneer SA 9500 ' 11 amplifier and if so do you also know the wiring set up for it , please and ta mucho

preamp to amp wiring

In the instance you are asking about, your amp has a preamp signal loop that is usually closed on the rear of the amp by a pair of jumpers going from the in to the out rca jacks. You need to remove & save those goodies. Then you can use 2 patch cords to connect the equalizer's line in and out jacks - you hook up your preamp's " line in" to this amp's " main out" rca jacks, and the preamp's "line out" to the amp's "line in" jacks. You should now be able to equalize the output of the amp. If you want to have an equalized signal running to a tape player/recorder simply use 2 more patch cords to hook up the equalizer to the tape unit in the same way using the "tape in" and "tape out" jacks on the equalizer.

re: preamp to amp wiring

hello effectively to connect the graphic equalizer to the sg550 amplifier sa 9500ii you must connect the pre-amp output of the amplifier to the main entrance of the equalizer and the output of this to the amplifier input by removing the connectors that mentioned in the previous response and once you can echo this equalizer any component that you connect in the amplifier is cd,dvd,deck,tuner etc. i have thas apliance an used as well and you get a very good quality in the audio playback
