No amplification Got this unit second hand. Little history. The output volume sounds as if there is no amplification. Same on any input

If the amplifer doesn't have a PHONO input, then you will most likely need an external phono preamplifer. Most vintage turntables and cartridges have too low a signal level to connect to todays modern amplifers that don't have phono inputs. An external preamplifier will also have the correct RIAA response curve for records. Without this curve, the recordings will sound awful.

Possible that the AUDIO OUTPUT SECTION is faulty. You need to use a audio signal tester to check and verify the section of amplification failure.
Check for dry soldering on the output IC, is so resolder the IC.
Also the Audio input/output must be checked with an external source to confirm the input and output stages.

The Marshall is a super clean acoustic amp.

The POD is overloading the amp.

Try the electric guitar input and keep the gain on the amp down, keep the EQ level and use the POD and the end volume to adjust the final volume.

The normal inputs is for a low output acoustic pickup - the POD is a high output electronic source.

Start with the Marshall gains low and get the clean sound good, then work on the gritty sound.

The amp is voiced for a sweet clean sound - if you want grit'n'ball change to a 50w Marshall valve head and a 4 X 12 cabinet.

Horses for courses

1. Do you have power to the unit. I assume yes.
2. Ensure the fader and balance is set to neutral to ensure you have output going to all the speakers.
3. Ensure the speakers are connected.
4. Ensure the speakers are not out of phase, if they are they will cancel each other out, and sound muted
5. Always test new model head units with a cd. not fm radio. Using fm radio on some head units will mute the sound if the station is not coming in clear enough.
6. Set your volume up a little, like on 15 or 20 (using the digital 40 level radios) (halfway in plain language)
7. Ensure the mute isnt on
8. If running through and amplifer, ensure the power, ground, remote, gain and phase are all correct.
9. Ensure rca input is going into the correct place on the amp
10. Ensure speaker output is actually connected to speakers.
hope this helps

Generally speaking of course, you would never direct the signal from an amplified output into a line level input, however with headphones the level of amplification required is so small that the signal will typically be even less what a line level input is expecting. So do you want to headphone output signal further?

Basically, if you connect a headphone output signal to a several thousand ohm line level input it will behave pretty much like a line level signal.

Therefore, I would try it as is first to see if your results are acceptable. The output level should range somewhere within what a line level range should be although you might have to turn the volume up more than you would have to if it were a line level out.

Just start with the volumes all the way down, then turn your monitor levels somewhere in the middle and then turn up the keyboard level and see how good the sound is.

You may be perfectly happy with the results, otherwise you could try a headphone amp, but be careful with the volumes

Here's a good article on this topic which should address any concerns:

This sounds like a power supply problem. The high voltage for the tubes is not right. Either you are missing an amplification stage because this or one of the coupling caps is faulty. I'd have to see the unit itself to give you any more details.

You could do a couple things if your head unit has all three outputs, then take them and hook them into the inputs. If you have just the front and the rear outputs, hook those to the inputs front and rear. Then hook the output of the 4 channel to the input of the mono block. I hope this helped

Eltax AVR-200 will start up in protection mode if the amplifer went into protection mode due to high volume before it was turned OFF and it will start at the same volume level as it had before power OFF.

To correct this you must shift to another input without signal, then turn the volume down before it goes into protection mode again.

The easiest solution to use your subwoofer is to buy an amp for it. Any old stereo receiver from a garage sale will probably do just fine.

1. Connect the mono RCA subwoofer output from your Sony with a 1xRCA-to-2xRCA splitter to both the left and right input of the cheap reciever's tape or aux input
   
2. connect both speaker outputs of the cheap reciever to the speaker input on your subwoofer. make sure both black (-) outputs on the reciever connect to the black input on the sub, and the red outputs (+) on the reciever are both connected to the red input on the subwoofer.
3. make sure the cheap receiver's volume is all the way down. turn your Sony up to about the loudest you'll listen to it. turn up the subwoofer amp until it's loud enough to sound good.
4. leave the subwoofer amp alone, the Sony volume will all you ever need to touch from now on.

You can even now turn off your subwoofer / adjust the volume easily now!
