Kenwood KR 9340 Receiver

[kwmrlg]

Anyone know anything about this receiver? Is it Quad? I searched AK but couldnt find anything on this specific model. A friend from my work has one and knowing that I was into vintage gear he asked me if I could find out. He says its not working (no sound from any of the speaker outputs) but does light up when turned on. Not being into electronic repairs myself, I suggested he take it to a tech that I've used for some of my Pioneer stuff. I hope he does get it restored, maybe he will get hooked on vintage gear too!

Kenwood KR-9340

RCV 73-76 Kenwood 45 Watts/Channel KR-9340 QUAD $750.

It appears that it was the second to top of the line Quadraphonic receiver that Kenwood made. I have no personal experience with Kenwood 4-channel receivers, but, I would imagine that it would be a good sounding unit when brought back to scratch.

Actually, for its time it was Kenwood's top Quad receiver. A later version, basically the same receiver, was billed as the 9940, but they are pretty much identical.

Nice looking receiver, but quads can be a bear to work on...lots of stuff crammed in there to get 4 discrete channels. I have one that has one channel out, I think - haven't gotten around to working on it yet.

My other Kenwoods are some of my favorite receivers - the tuners are to die for. The KR-6400 I had (now MG196's) was absolutely amazing.

Check the easy stuff - fuses, clean the tape monitor switches, see if you can get an output from the headphone jack, or pre outs (if available) and main ins work, etc.

Congrats, and have fun!

Thanks

Thanks for your replies guys. I'll keep you posted on our progress. I'm hoping maybe he will donate the Kenwood to me!

good luck on the Quad-Kenny

hey Ken :wave:

Hey Greg! It's good to be back - been gone for a while. The HPM's are still belting out the tunes and looking mighty fine with their new grille covers. :thmbsp:

I found one

dropped into one of my regular shops and picked up a 9340 with the KCD-2 module(not sure what significance this is but apparently some). hope to get some pics later.

first picture in a year

I have finally got internet at home agian and can post pics. here is the 9340 I just bought today.

Very nice. Has the same asthetics as my KT-8005 tuner, with the two tone face and beveled sides. c.1973?

Regards,

Ken

Nice! :thmbsp: I think I must have it's little brother, the KR-6340. Sounds great, and looks near mint, other than the wooden sides, but needs the pots & switches cleaned. I just got back from ratshack, and they stopped selling the big cans of DeoxIT, so I got the tiny combo pack, with Pro Gold.

Picked up a 9940 a couple weeks ago. Didn't remember I was given a complete non working unit some time ago. Both have the decoders. The working unit has a very nice sound but then so does my 4200. :yes:

decoder

What is the significance of it? What if I remove it?

The unit has a CD-4 position on the selector switch. what is it for? It appears to use the same inputs as phono 2. Now CDs weren't around in 73 so it must be for something else.

FWIW, I did a completed ebay search and found one unit with decoder for 86US

Does absolutely nothing for 2-channel (IIRC). Nothing happens when removed. Need a ofur channel signal for use. Though I've been told my Marantz 4240 will do 4 channel with the right DVD player.

RCV 73-76 Kenwood 45 Watts/Channel KR-9340 QUAD $750.

Hey, can ya tell me about the KR-6340? I dunno for sure the wattage of the "smaller" one. Thanx much! Also, if anyone happens across an EXTRA CD-4 cartridge for it, can ya please give me a yell? :thmbsp:

Cd-4

The unit has a CD-4 position on the selector switch. What is it for? It appears to use the same inputs as phono 2. Now CDs weren't around in 73 so it must be for something else.

CD-4 was one of the three major four channel disc formats of the quadraphonic era. The CD-4 system used a high frequency (30kHz.) frequency modulated carrier frequency to encode the surround channels information on the vinyl disc. The CD-4 demodulator would demodulate the signal and combine it with the non-frequency modulated signal from the record to produce four fairly discrete channels of sound. In order to use this system one needs:

1. CD-4 encoded record aka Quadradisc
2. CD-4 capable cartridge i.e. one with a frequency response to 45kHz.
3. CD-4 demodulator
4. four channels of amplification
5. four speakers

With a good record, cartridge and demodulator, the CD-4 system can deliver surprisingly good results. CD-4 records, cartridges and demodulators show up quite often on the popular internet auction site.

RCV 73-76 Kenwood 17 Watts/Channel KR-6340 QUAD $390.

It appears that it was the second from the bottom of the line Quadraphonic receiver that Kenwood made. I have no personal experience with this Kenwood 4-channel receiver.

 

[spaceman]

Thanx much, tcdriver. :thmbsp: I also found some other info, I think it was here at AK or maybe a web search. This one is 47watts x2 or 17watts x4. Not a "beast", but I still like it. :yes:

I bought a 9340 new in 1973 or 74. Nice unit. The whole CD-4 business was a bit tricky at times, but sounded nice when working right. 95% of the time I played mine using just stereo records played through the SQ matrix position. Seemed a bit nicer than the RM matrix position.

My original 9340 got away from me many years ago. But nostalgia forced me to dig up another, this time a 9940. Identical with the exception of power output. The 9340 was good for 40watts/channel, and the 9940 was upped to 50 watts/channel.

IIRC, some of the "lesser" model Kenwood quads actually had the advantage of "strapped" output for stereo. -For example-, if the receiver put out 30 per channel in quad, it would put out 60 per channel in stereo. Something like that. The 9340 and 9940 didn't have that advantage.

Kr-5340

I would assume my KR-5340 is the bottom of the rung for Kenwood's quad receivers. I liked the way it looked and got it. Everything works, and the receiver sounds great, just needed some deoxit on the controls. Suppose I should try to locate some quad sources, and besides the receiver, anything else I need?
