Pioneer SX-6: One of the 'infamous ones'


'Infamous' because it marked the end of the glorious and fabled "Silver Era" as the 1980-81 line went out the doors.


'Frustrating' because all the hallmarks of traditional receiver design were tossed, including the taut pull and play as the large knob turned with one's hand, hell even spun wildly if you had a daredevil fling at it to launch the pointer across the dial and there you had it...it was precise and did as told while feeling just perfect while doing so.


Colored lights told you which functions were engaged and needles twisted like an itchy back against the corner light pole telling you to anticipate the program and properly tuned stations. Your parents and grandparents might have had mostly the car radio with a light in the dial or some old home set with a 'magic eye' tube, maybe a suitcase radio-phono or a console. Still, YOU the children of the late 50s and 1960s, YOU got the really neat stuff, from Voice of Music maybe up through Bell, Fisher. Marantz, Sansui, Harman Kardon...


*And never get me wrong...I adore antique radios a ton as well...


Moving at warp speed we reach 1980 again and then one more year for the Pioneer SX-6. "What the hell happened", you were thinking, "I almost bought an SX-1250 once and it's TOO LATE"???


I hear you. Even with 30 years gone by and all the others designed like and after SX-6 and it's line it still seems to be from the planet Ork to me. Still, it was the Mother of most 80s stereo gear.

 
"Computer Controlled" it says in the left top corner of the faceplate. Roland was using those very words on its percussion machines at the time, the famous TR-series of which TR-808 would become the absolute legend. Everybody wanted you the consumer to know that logic and memory were a large part of your products, whether it was done well or not. Or course, the technology was so marginal them that the baby steps might not actually matter, still the door was wide open to 2011.
 

That having been said, let's see how this all worked out as I've seen but 2-3 of them in my life and this one is the only one I've been able to operate.
 

I have an example of the first Dolby Surround audio/video receiver they sold in America, the VSX-5000 and it tells me as well as this that somebody at Pioneer thought very hard and deeply about the end product. Even if some features seem not quite developed and odd the experiences of the buyers were considered before and after. Pioneer products create their genres as much as genres create Pioneer products.

 
Without a long look and maybe the manual you can poke about and learn your receiver's controls with a little time. Intuitiveness pays off as both the VSX-5000 nor the SX-6 are not conventional sets you can instantly grasp at first use (certainly useful, and helpful in the long run). Both suffer from really hard to read labelling and tiny buttons on the bottom row. They end up running seek/manual tuning switch, phono (magnetic only), A/B outputs (tucked away on the left side, thank you), tape 1 and 2, mono/stereo, subsonic filter (Rumble) and loudness switches down there in almost Fantastic Voyage size. Other controls are two large volume pads, preset scan, muting (is that ever weird, it kinda fades out like a hung digital audio signal, a flat ring that falls off rapidly like reverb, phono, aux, 8 presets per band (AM and FM), power and three conventional pots for bass, treble and balance. A standard 1/4" stereo headphone jack is provided for personal listening.


Unique features (for 1980s Pioneers as they don't appear on other brands) include an AM stereo out jack so that if you ever had seen one you could plug into the one RCA and stereo out in to the adapter section or something (if you've seen this AMS adapter of theirs or anybodies EVER that was how you would convert the AM to stereo, through Tape 2), and AM stereo is more or less gone after 30 years as well. Pioneer continued the handy FM step/flag graphic display in the LED signal meter with only THREE this time and a horizontal 6 LED per side display for output metering, MPX stereo lamp, AM and FM lamps and a red lamp for each of the 8 presets (AM and FM shared).


When you turn the set on the last volume level in 2 digits flash briefly as it finishes powering up. Changing the volume raises and lowers the count and if you are tuning in the radio the display switches back and forth as such. If you are in SCAN mode and tune up or down the preset lamps chase like a scanner until you stop tuning or use manual. If you press any preset button while in scan this way you can set the presets! That is mindblowing just a bit.

 
Tuning steps switch on the back for US and foreign channel widths. a full complement of inputs and outputs (tape 1 and 2/adapter), phono with grounding post, aux, AM 9/10 kHz channel step, AM stereo composite out (single RCA), AM ferrite bar, external AM terminal post as well as 3 for FM 300 and 75 ohms, A and B speaker terminals (push toward the connection to lock) and two AC non-polarized convenience outlets 50W switched and 200W unswitched.

 
The ID tag on the back carries the E-P diamond indicating military sales qualification, however there is no outward indication there of any mutliple power adaptor. Lest I forget, there is a second grounding terminal between the ferrite bar mount and the memory's 2 AA cell compartment (a common setup in those days--see Technics 3 AA especially).

 
I will be back with part two featuring a run with speakers and technical information I can gather and not just headphones, tape loop, and my Philips GA-202...and PICTURES, plus my summation of this 30 year old agent of cranky change.

I got 'em...The world demands my beauty sleep at some point in time.

(Not like Woody Allen had but he's not beautiful neither)

Scribbling as well.

If they had demanded the Bible in three days, they would still be dead!

I could take pics of my SX-8 if that would help.

I have an A-7 amp from the "Communication Series" as well.

I know...I'm not slow or whatever. It boils down having troubles what involve my Presario losing the video and having to reboot too much and I had to temporarily shut it down then move to this laptop. I was my birthday Sunday, I really had to get some help with groceries Monday and I haven't had much time to try and retrieve a few of the newer files no saved to CD or DVD yet.

I have 30GB of archived programs and photos, saved music. Obviously it's not going to even ghost with only a 30 GB laptop drive.

I know the outputs run but maybe the A speaker switch needs some TLC (as I about took my left ear out when I got the speakers)

Maybe I'll have to do a 40th anniversary story about bringing an SX-525 back to specs as well as my old 525 came back to me yesterday as well.

Meanwhile if I don't pass the HUD inspection of the 5th I can't rest until the Congress defaults on our loans and leaves me in the street anyhow.

I'll get it. Just hang on.

It's all good Steven. Things will work out for you. *yes*

Anyway, here's a picture of my SX-8 I promised. It's not really a great picture, but it's a placeholder for now. This just gives an idea of how it generally looks.

Oh, and it's a bit beat up looking. I got it like that from eBay 8 years ago. It was to replace a receiver I had bought new 4 years prior. It was acting up badly, and I figured why not get one that was a tank and sounded great. I fell in love with the design of the Communication Series components right away and wanted one.

Whatever was wrong with my old computer seems to have been resolved...whether an OS update did it or what...we shall see and I will retake some photos today as I simply cannot find them.

I have a lot of people and bills to pay today, groceries too! I'll get finished this weekend and see about answering any questions.

I think the finish doesn't hold up well, maybe some Marantz users could comment on their golden/champagne finishes.

My all time favorite is my SX-525. It's straightforward and the layout is classic like the ham gear and communications receivers I so love (Hammarlund, Hallicrafters, Lafayette, Realistic DX-160)...plus it's got a great tuner and the nicest 17 wpc amp. It was my first Pioneer receiver well over a decade ago. My first (and second as well) cars made the same visual impressions on me-1969 Dart sedan and a 1972 Plymouth Duster Twister. Something about being 5 or six taught me what classic design meant to me.

Hey Bezel, thanks for the review. The SX-6 was my first receiver right out of college. I was never one for all of those knobby recievers of old, but I'm not putting them down for those of you who love them. Like Melon, I fell for the Communication Series. I now have all of seperate components, i.e amps, tuners, receivers, cassette decks, etc., except for some of the lower end. I find the cassette decks real easy to work on, because, for the most part, their problems usually are solved with a belt change and a good cleaning/lubing on the autoreverse head. The companion deck to the SX-6 receiver, the CT-6R, is a real workhorse, and value. I see them all the time on ebay, and from what I read, they just need a cleaning and a belt to get them up and running. I would buy them, but I already have too many!

Hey Melon, I like your SX-8. *Hi5* I too have one, and use mine at work, along with the matching CT-8R deck, and the accessories, such as the RG-9, SR-9, and SG-9. I get a lot of positive comments from my coworkers. I love the convenience of changing stations to one of the presets. Much easier than rotating that big dial. I finally adjusted and cleaned mine this past winter, and it is sounding and working better than ever.

Thanks for that review Bezel. The SX-6 was my first purchased receiver right out of college, when I finally had some money. I wasn't into the knobby receivers of previous years. Not that I am putting those down, but they weren't my preference. Besides, I liked the convenience of pressing a button to change stations to a preset one. I still have that receiver. Only now, thanks to epay, I have almost all of the other Communication Series components, such as the amps, tuners, decks, etc. Except for a few of the lower range ones. I still to this day like their style. I've found that the decks in this series are easy to work on, and usually a belt change, and a cleaning/lubing of the reverse head is all that is required to get them up and running. I have as yet to experience the drive issues that some who used to repair these units often bring up. But, then I try not to let my units get too hot. I believe heat is the primary reason for the failures of the drive units.

The matching deck for that SX-6, the CT-6R, is a good deck that is a bargain. I see them all the time on epay, and from the descriptions, they usually need a belt and a cleaning/lubing of the reverse head to get them up and running. I would buy them, but I have too many already! Mine always works, even after sitting for long periods. A real workhorse.

Hey Melon, I like your SX-8. *Hi5* I too have one. I use it at work, with the matching CT-8R deck, and the add on accessories, such as the SG-9, SR-9, and RG-9. I get a lot of positive comments from my coworkers when they see my setup. The younger ones don't know what to think, as they aren't used to that type of stereo setup! I finally got around to adjusting the amp section this past winter, and it sounds and operates better than ever. I have a few more that I need to work on, but this one is the work horse. It replaced my A-8/F-9, which I brought back to clean and adjust. I'll get around to that one day.

Sorry for the late response.

The finish on every one of my Communication Series components held up quite well. Even my daily used A-7 amp looks (and sounds) great. They surely are some of my favorite looking components along with the Akai GX-F31/51/71/91 cassette decks.

I'll probably get to work on the rest of this by fall as well. It's gnarly when you have to wonder if you'll live in a tree, even if your predicament is still a distant 5th or so. I have a friend who's bought from me for his classrooms for a few years and I needed the help badly so he's looking over the SX-6 and VSX-5000. Once in a while he brings stuff back when it's no longer needed so I can resell it (or in the case of my Betamaxes, use them). He also supervises the student cable TV station and is in the coaching staff for two sports. I used to do lawn work going back 15 years or so when his oldest was about 3. He usually asks me for gear, and really I haven't had to ask myself much really once I've sold once until recently. I was asked about an old CD changer two days back and it was looked over and sold yesterday.

Yep, it came with the returned Betas last year. $5 was fine, a 5-disc Kenwood from '95.

Many of my friends aren't rich, some live in group homes and are on an allowance and I've furnished them with gear on a few bucks at a time. It's cool to see them trade it around and then I see how they hold up and can keep them up some etc. When I find my old stuff in a pawn I can smile because I know the owner approved of my work.

Sometimes I buy it back and use it or send it back around. It all comes to how I got the free pair of Pioneer CS-A31 (a nice guy I met through CL and along the way he bought a Hallicrafters, traded E-V Aristocrat cabs for 150w Pioneer PA 12s and sent the lone Knight KN-800 through TH to complete somebody's long search).

Something works.

So, now that I'm beginning to add the King back to Burger...*flame*

Thanks for the keen review, Mr. Shalit!*wink**grin*

the sx-6 is a intresting receiver, nice review btw, this is one of the receivers i love to hate, i hate it cause its cheap as it is ugly, but love it cause it sounds decent, i found my sx-6 in the trash a few years back, it marks the beginning of the bpc death that has casted misery and blight on the hi-fi gear of today. but still for what it is, all in all, a decent receiver..
