SX-1600 + KD-491F

Thank you for your quick response. Just so you'll know, I also have 4 S-DF1-K speakers: 15-100W, 8 ohms....a PD-F407 CD player....a Pioneer CT-300 dual tape deck. Want something that will run all of these plus the KD-491F. Thanks again. KB

Appreciate the additional information.

To recap what you need is a receiver that can accommodate:
4 - Pioneer S-DF1-K (15-100W, 8 ohms)
1 - Pioneer PD-F407 25 Disc CD Player
1 - Pioneer CT-300 dual tape deck
1 - Kenwood KD-491F turntable

Possible choices are (keeping in mind that the power output should be less if not equal to 100 watts and a turntable/phono input):
i. Onkyo TX-8522 Stereo Receiver;
ii. Yamaha RX-397 100 Watt Natural Sound AM/FM Stereo Receiver;
iii. Sony STR DE695 AV receiver;
iv. Teac AG-790 200 Watt Stereo Receiver;
v. Denon AVR 888 - AV receiver - 7.1 channel.

Some of the above also includes feature(s) to hook up to your video system. Some may even require a fifth speaker (subwoofer).

Incidentally, you can also choose another brand/model even without a turntable/phono input. As initially posted, a turntable/phone to line level pre-amplifier is only required. Here are some examples:
a. XP200 Turntable Preamp - Nano Series;
b. Pyle® Pro PP999 Phono Preamplifier;
c. Pro-Ject Phono Box Turntable Preamplifier;
d. Radial J33 RIAA Turntable Preamp Direct Box

Good luck with your project.

Hello, I have an old SX-1600 stereo receiver that has a short in it. Shipped off once already to be fixed. It worked ok for about a year. Now, it's doing the same thing. Don't know where to send it...


Hi,

Most current receivers no longer include a PHONO input. Perhaps what could be done is to purchase a phono to line level pre-amplifier to go along in your purchase for a new receiver.

Will scout around for receivers and post back additional information.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

Is it totaly ok to just connect one pair of JBL Control 1 speakers to this receiver? Here are some of the specs. Frequency Response: 120 Hz to 20 kHz Power Capacity: 150 W Sensitivity 87 dB SPL Nominal...


The only relevant speaker spec is the impedance. As you probably realize the Pioneer SX-255R recommends 8 - 16 ohm speakers.

Four ohms is on the hairy edge of too low. You could certainly try it but if any strain or excessive volume is used you could see something go poof!

The low end of 120Hz says don't push the bass to them.

How to fit 2 more additional speakers to a standard 2 speaker stereo system each speaker has only 2 wires + & - , is there a anything avalible to branch the 4 existing wires to 8 wires .


You'll either double or half the ohm load if you do this. If you double the ohm load, you'll half the volume. If you half the ohm load, unless your receiver is rated for that load (very unlikely), you'll overdrive the amp and blow it.

Look on the back of the receiver. It will tell you what ohm load it's rated for. Usually, it's 8 ohms. If you are using 8 ohm speakers (virtually all home speakers), putting more than one speaker on a channel will kill the poor thing.

If you want more speakers, add another amp, or get a receiver capable of running the number of speakers you want.

Pioneer sx-255r can i connect 6 - 8 ohms


Yes, you can use them but be careful. These are not necessarily robust speakers. If they sound strained, back off.

When I turn on the player...the "PROTECT" message comes up... I would like to know how to start this player...or how to bypass this message so it pplays. Hope somebody out there knows the...


protect means that the speakers are improperly hooked up or just not compatible with the amp.

ensure that the speakers are 8-16 ohms, that no wires are crossed, and no wire strands are loose, which could touch and short. a 4 ohm speaker or a short in the wiring is almost always the cause of a protect error.

if all of this is checked, and it still says "protect" then it is fried.

Run 4 ohm on yami 1600


The manual says...

"If you are to use 6 ohm speakers, be sure to set the "SP IMP" to "6 ohm Min" before using this unit (see page 30). 4 ohm speakers can be used as the front speakers (see page 118)." ... which basically says the same thing in a table.

Set it for 6 ohms and try ity out. If it exhibits any problems like the amp cutting off you might want to lower the volume or analyze it to see if the 4 ohm guys are the problem.

BTW: That spec is just a nominal value. At various frequencies every speaker's impedance changes. The proof is in the pudding. The Yami won't self destruct unless you crank it to the stops and ignore the audible warnings of stress.

Pioneer sx-205 gives a overload warning and cuts in and out when tuner or cd is playing


Does it play normal on any sources, or do you only have the tuner and CD for available sources?

There are many different things that can cause this type of problem.

It could be bad solder connections on in the amplifier circuit or power supply, it could be a bad speaker or a bad output channel inside the receiver if this happens only when it gets turned up loud.

The overload warning happens when the amplifier circuit has excessive current or DC voltage on the outputs. Unfortunately the only way to determain if it is the speakers is to change them with other known good speakers and see if it still happens. But before buying any speakers you need to have the receiver ruled out as the source of the problem.

It can also go into overload if you have the wrong type of speakers connected, or too many speakers connected. Each speaker jack should only have one speaker connected toit. If you are using for example, 4 speakers connected to the "A" speaker jacks meant for just 2 speakers, it will create a load to the amplifier that the amplifier is not rated for.
Look on the back of the receiver and it will have listed the proper impeadance for your receiver. Most will say:

8 ohms or more "A" or "B" speakers
16 ohms "A" and "B" speakers

That means you must use 8 ohm or higher ohm rated speakers if you are using only speakers"A" or only speakers "B", but can not use 8 ohm speakers if you are using speakers "A" and "B" at the same time. Then they must be 16 ohm speakers.

Two 8 ohm speakers in one speaker jack is a 4 ohm load, that is why you can not use more than 1 speaker per speaker jack.

I hope you found this information useful, and if I can be more help just let me know.

This is not a pioneer vsx-454 receiver problem


I would not recomend doing this because the 4 ohm speaker is not enough to offset the 32 ohm speaker and the amp will have problems keeping up with the power consumption of the speakers and will eventully overheat and cause damage! (it will work but not well and not without risk to your amp!)
Please rate this quick response
Thank
You!

SX-1600 + KD-491F


Hi again,

It would seem that you posted the problem here also. With your kind permission, I will repost my excerpts of my responses that others may benefit on similar concerns.

A. Most current receivers no longer include a PHONO input. Perhaps what could be done is to purchase a phono to line level pre-amplifier to go along in your purchase for a new receiver.

I was made to understand that the Pioneer SX-1600 is prone to speaker output problems which could either be:
1. the speaker relay (protection); and/or
2. the amp, STK4191II Stereo Module.

Either should be relatively easy to work on and perhaps you can try the services of a locally available qualified electronic technician since the repairs would not be too specialized. The service manual may be of help (or at least a schematic , they may be downloaded from here and here).

B. To recap what you need is a receiver that can accommodate:
4 - Pioneer S-DF1-K (15-100W, 8 ohms)
1 - Pioneer PD-F407 25 Disc CD Player
1 - Pioneer CT-300 dual tape deck
1 - Kenwood KD-491F turntable

C. Possible choices are (keeping in mind that the power output should be less if not equal to 100 watts and a turntable/phono input):
i. Onkyo TX-8522 Stereo Receiver;
ii. Yamaha RX-397 100 Watt Natural Sound AM/FM Stereo Receiver;
iii. Sony STR DE695 AV receiver;
iv. Teac AG-790 200 Watt Stereo Receiver;
v. Denon AVR 888 - AV receiver - 7.1 channel.

Some of the above also includes feature(s) to hook up to your video system. Some may even require a fifth speaker (subwoofer).

Incidentally, you can also choose another brand/model even without a turntable/phono input. As initially posted, a turntable/phone to line level pre-amplifier is only required. Here are some examples:
a. XP200 Turntable Preamp - Nano Series;
b. Pyle® Pro PP999 Phono Preamplifier;
c. Pro-Ject Phono Box Turntable Preamplifier;
d. Radial J33 RIAA Turntable Preamp Direct Box

Good luck with your project.
