YOUR DIFFERENTIAL AMPLIFIER IN THE FRONT END OF THE POWER AMP STAGE NEEDS TO BE CHANGED.
USUALLY THIS IS A DUAL TRANSISTOR WITH EITHER 5 OR 6 LEGS,OR AN IC WITH 8 PINS(4+4)

No sound out of left channel pioneer vsx1123k

Make sure that you have analogue stereo sources (red & white phono/RCA) connected to any input that you want to have routed to Zone 2.

Check your speaker connections for Zone 2: Correct sockets, and make sure the wires are connected properly and there's no little strands bridging between the black and red terminals on the amp or at the speaker ends.

That's about it.

If there's no sound on one channel then it's most likely to be either a bad speaker/speaker cable connection, or a broken source cable. Try the FM/AM radio (hook up an aerial temporary). That'll be guaranteed to be either stereo or at least dual mono so both channels should work.

My Pioneer PL-990 Turntable only outputs sound through the white wire. Only a quiet buzz comes through the red wire.

The red wire is the right channel, so going back to your amp, get a single phono plug with with the wire exposed, so you can touch the wire. Then remove the turntable connections. With the amp on plug the the lose wire plug into each channel and check if the sound on the right is still low. If it is then there's a problem with the magnetic cartridge pre-amp inside the amp. They are often located near the phono socket on a seperate PC board, but if not just follow the red wire to the main board. Chances are it will be an IC that's failed.
If it has a strong buzz at the back of the amp. Then I should replace the wire between the turntable and the amp. Or the right phono plug that connects to the amp.

White noise in left channel on my Vestax PMC 06 pro-a DJ mixer

try it with nothing plugged in to the inputs, if there is no noise. most likely its the turntable, cd player, or whatever the input is is the problem. or try plugging the mixer into a different area of the house/room. its like if you were to put your cell phone by a mixer, or speakers.

Pioneer pl-200 turntable one channel is dull and muffled

I think we need to do more diagnosis. Did you try swapping the channel cables Left-to-Right so you're sure it is in the TT and not in your Phono preamp?
If it's still in the TT and always on the same channel with two different cartridges you probably have a wire problem in the tonearm/shell or interface between them.

SX-1600 + KD-491F

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.

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).

c. Pro-Ject Phono Box Turntable Preamplifier;
d. Radial J33 RIAA Turntable Preamp Direct Box

Good luck with your project.

Pioneer vsa e06

depends what audio outputs you have on the sky box,analogue (two phono usually red for right channel and white left channel)in which case just use phono leads to the phono inputs,Optical(toslink),connect an optical cable from the output to the optical input on the dvd channel of the pioneer,coaxial (spdif)connect to spdif input on the laser disk input of the pioneer,dont connect to the attenuated spdif.In the unlikeley event of the sky box not having any audio outputs,just use the outputs from the tv to the pioneer.The optical digital input gives the best quality on the vsa eo6

Poor sound

You need to connect most turntables to a PHONO input or buy a PHONO preamp. Many newer receivers do not have a PHONO input. The AUX port you are using would work fine for a device like a CD player, but turntables need to be amplified. You can buy an external Phono pre-amp from Radio Shack. I don't know anything about this site, but something like this device should work for you. http://www.phonopreamps.com/tc400pp.html
