I am in the process of acquiring a pre used turntable ( Pioneer/akai/sony type) and start a vinyl setup. But I found that my Yamaha-473 AVR does not have any `phono' option shown anywhere in the front/back panels. The manual also does not have any mention of ` phono' input. So I decided to use my other stereo setup ( BPL Sanyo).The front panel is having a phono selector button but the back panel is having only one `Hole'. I am attaching some snaps. Can anybody help please? Whether a turntable can be connected and how? Any modification/ enhancement required? I am not a computer/electronic guy, so not able to understand this.

does that look like a headphone jack/will it fit one?

but I still wonder if it's a proper phono input, or just another input for a ceramic cartridge

vnmathur57,
Could you post a larger image of these ( 2,3 snaps), else a macro shot/close up.
this can help FM for easy identification.
 
Don't take tension. It's not for phono cartridge. Its 3.5mm mono audio jack. It used to be external microphone input for recording purpose. I have one "tonytone" tape recorder with same pin and label.

I am familiar with this as my very first purchased music system was the CWX79, the next higher model. The CWX59, 69 and 79 came with a phono stage with a headphone socket (wonder why they used the headphone socket). You'd have to wire your turntable through a stereo headphone jack (the regular type one would use with the computer). Another point to note that this phono preamp supported ceramic carts only. So if the TT which you buy comes with a magnetic cart, it wont work anyways. I have played my dad's garrard sp25 with EEI CS2000 ceramic cart through this input and it sounded quite good, though not too great, but listenable. One would have to play around with the inbuilt graphic equalizer to get some listenable sounds out of it. Hope this helps.

On another note, on the CWX79, that entire phonostage board was populated with components and a bar IC. On yours, seems like its kept very basic with just a few impedance loading components.

I am quite well versed with these BPL CWX series systems, please feel free to ask further queries. They were good in their day, mine even had dolby noise reduction on the tape deck. Although the system and its matching cd player are long gone, I still use the floorstanders I got with it.

Yes. It is meant for mono ceramic cartridge and cannot be used for magnetic pick up unless a phono stage is used and the output from phono stage to aux is connected

Was this a rebadged D1000? Know as another model too under the Sanyo badge cause thats what it was underneath. This was a Mini Hi Fi system they came with monster speakers and then later shifted to book shelves.

Stupid of BPL to provide a stereo mini jack as an input when the CD Input is given a RCA. Even more stupid of them to provide a proprietary CD input as well.

However; I do recall their system sounding the best in comparison to Philips Power House, etc.
 
Thanks all FMs for the replies.On the PCB near this jack it is written R Tp Lin L. So I think it is for stereo. The sound system otherwise is a full fledged stereo with Dolby(B) NR and a properly marked separate Headphone jack in the front . So it is unlikely that they will provide a mono input jack in the back. However, it appears that the jack is having limitations w.r.t cartridges and I may have to buy an intermediate device ( phonostage ?). Now can anybody guide me please, what device I should buy( not very expensive pl)? Also, can this device be used to play the TT though the Yamaha-sonodyne setup also?
 
plug a regular audio source into that, play at very low volume. if you can hear it normally, you will need a seperate phono stage. else if its distorting heavily with high volume levels, it should work as a phono stage :)

No, the CWX79 was not the rebadged D1000. BPL had basically 2 series of hi-fi products back in the 1990s. The CWX series which was direct competition for the Philips power houses and the D-series which were essentially combo CD systems. These were the CWX models:

CWX 59 usually sold with book shelf speakers
CWX 69 usually sold with BPL TBSS mini floor standing speakers
CWX 79 usually sold with the 700T symphony series towers

They had essentially the same configuration but different power ratings and the CWX79 came with a motorized volume control (and remote) and with dolby-b on the tape deck. Don't think the CWX59 had a phono input. The matching ACD player was available as a component add-on for theese systems. The CWX 79 was the best of the lot and it was arguably the best system in its class, available in India at the time. I remember opening my CWX79 up and finding PCBs with components which were made in Taiwan (suggesting that these were imported as assembled or semi assembled kits and assembled by BPL). The 700T symphony towers had original Japanese drivers.

The D-series were launched iin 3 models:

D1000 with 1000T symphony series towers (bigger brother of the 700T)
D500
D100

Unlike the CWX series which were assentially ampli-cassette-deck-receivers, the D-series had inbuilt audio CD players as well. The D-series was indeed re-badged Sanyo produce. Just imported, re-badged and sold in India. The D1000 with the 1000T speakers was by far the best audio system available in India at the time.

The 1000T symphony towers were essentially the 700T towers with what BPL called a super tweeter. Both the 1000T and 700T towers are big and packed a solid punch. BPL later packaged the D1000 with bookshelf speakers to make it appealing for use in apartments, nevertheless its sound quality remained. Too bad these baddies faded away with the BPL brand in the early 2000s. Philips powerhouses were no match for these BPL systems. Also the BPL systems were much more expensive than the Philips systems.

Yes, it was stupid to use a stereo earphone jack for a phono input. Can't understand the logic here. My CWX79 also had a CD Input and a Video input (for connecting a VCR, apparently for the rudimentary home theatre setups of those days).

I had the system and used it happily until one day, my NAD106/216thx came home and simply blew it away.

On another note, I worked for BPL Mobile and had access to their entire catalogue of products at factory price (could purchase 1 product per year of employment with a further Rs.5000 discount on factory price). Had done a lot of research on their audio system catalogue as it was my first steps into the world of hi-fi outside DIY and I wanted to make it count. I had researched both the CWX and the D-series extensively before deciding on the CWX79. I would have bought the D1000 but it cost Rs.22000/- in 1995 which was a lot of money for me back then.

The phono socket at the back on the CWX69 and CWX79 is stereo indeed, and for use with Ceramic Cartridges (not magnetic cartridges). There is a separate headphone jack on the front faceplate of the system. Again, it is not a MONO input. You can use it with a stereo ceramic cargridge. You will have to use a phonostage only if you use a magnetic cartridge (on your CWX69).

Phonostages come in a variety of shapes, sizes, price brackets and with a variety of sound signatures and features. It would be a good idea to shortlist the TT first and ascertain if it has a magnetic or ceramic cart and then decide on the phono stage. Phonostages can be made easily if you are a DIYer. If not, I am sure you will get a lot of opinions about which phonostage to buy, out here on our lovely forum. I personal suggestion is to try and start with something basic and inexpensive and upgrade later.
 
^^^ Excellent post. Yes I also did a lot of research and zeroed on to this, though expensive by the prevailing standards way back in '91. It was giving tough competition to other Cosmic/Pulz/imported systems which my freinds erwe having.The system has been opened for the first time by me for taking snaps.

The CWX79 which I used had a stereo phono input. It was stupid of BPL to use a headphone jack (like the ones commonly found on walk-mans and portable cd players for connecting headphones). This "unique" stereo phono input socket was wired to a bar-IC phono stage (for ceramic carts).

On another note, I remember seeing a similar Japanese Sanyo version of the CWX79 in a magazine back then where they claimed that a stereo ceramic cart could be connected directly to this phono input and if one had a magnetic cartridge, one could use an external magnetic phonostage with its output connected into this ceramic phono input (guess the idea was for the user to continue to use the phono selector on the front faceplate :) )

The CWX 79 had lovely selector buttons with fade out and fade in while switching between sources. These were also switchable on the remote.

Very true, my CWX79 and CD79 CD player ran flawlessly from 1995 till 2006 when I gave them away, no breakdowns what so ever. I still use the 700T symphony towers with my NAD rack. These have imported Sanyo drivers and cross overs, the baffles however, are made in India of course. Yes, the whole system was expensive back in 1995 when I bought it, even though I was buying at factory price with a Rs.5k discount. I only opened up the CWX79 out of curiosity and not for any other reason. On another note, the stereo digital tuner was also a gem.

Though the exact make/model of TT is not yet final, in my target price range I hope to get an old model TT with MM cartridge only. Yes I have come across some DIY things on this forum but I know I'll never be able to put it together. So I'll buy only readymade/off-the-shelf stuff. Can anybody suggest a good but inexpensive one?
 
you can probably take a look at this: http://www.hifivision.com/sale-owner/44355-technolink-tc-754-t-preamp-mm-phono-input.html

one piece of advise is that phonostages in India tend to be heavily priced, starting in the 5k range for a simple el-cheapo one, thanks to the revival of interest in vinyl. When I was using my BPL CWX79, I bought a Teac P988 turntable with a magnetic cart during one of my US trips, I also picked up a $5 el-cheapo phonostage on ebay.com, which was something like this: RIAA Phono Preamp Record Player Turntable Amplifier Amp | eBay

It was very basic but it got me off to a good start. I also spent an extra dollar on a 220v to 110v converter from k-mart, for it.
