If you switch the speakers, the sound goes to the right? if yes, your amplifier will be damaged. if not, you speaker or speaker cable is damaged. If you don't have the skills to repair an amplifier, don't even open the thing. Just visit a repair centre, to limit the damage (and costs for repair)
Manrantz often uses components with different (own) codes, so it could be difficult to replace any component you find defective. Without a service manual I even would not start a repair.

SOURCE: scratching sound in speaker conected to left channel

invert the speaker cables if the problem went to right speaker you will find a problem in your left speaker(cable or speaker)-if not you will have a problem in your amp itself.

SOURCE: Muffled/bad sound on 1 channel of Marantz PM4400 amplifier

Go directly to the main amp, follow the leads from the speaker terminals. And you should find something on an heatsink. If there are two transistors see if they are running hotter than the other channel. If you see any damage to them (compare with good channel) replace both!
If all you see is a black box with pins coming out of it you need to replace that. They sometimes have the letters STK on them.
Replace both types with the letters and numbers of the same type. IE 2SC 1220 or STK 589.

SOURCE: qsc 2450 amplifier not putting out equal sound to

First of all , the fault of a unequal volume levels is a fault to be looked in with some expertise. This is because of the fact that there is no failure but a difference in gain in some stages. If you have crossed over the speakers and confirmed that the fault is definitly in the amplifier. Now you will need to check first with a multimeter for diffferent bias in the preamp and power amp stages. If you have evidencce of a difference cross check to confirm. Next apply an audio signal from an injector and test from the preamp to the power amp. The section where the gain was noticed must be looked into and the gain corrected by checking variation of resistor/ capacitor values. You will need to replace fromt he working side- crossing the good part- to confirm the part before you buy and replace. Try this out but do it with caution when the circuit is powered , attempt only if confident and familiar with circuits. Hope I could help. Good day

SOURCE: Poor sound from 1 channel

Hi...
My 1st thought would be a broken contact or 2 inside on the main volume control... Is the balance set to middle?
Is it the same with headphones?

Sound comes through only one speaker at a time.


Is the sound on both channels on a pair of headphones? If it is suspect a faulty headphone socket, especially if the speakers are cut out when the headphone jack is inserted - normally.

Most voices come out of the centre channel. Put your ear to that to see if it is working. If it is not then you might have somehow managed to switch it off. Check the cable connections to the speaker also.

ONLY GETTING MUFFLED SOUND FROM ONE OF MY MACKIE SRM V2 SPEAKERS,HAVE CHANGED DIAPHRAM BUT PROBLEM STILL THERE


If you've changed the tweeter and the sound is still muffled the fault is with the HF amp, or the cross-over. You will have to send the amp assembly for repair as it is all surface mount components in there -nothing you will be able to fix yourself. Sorry for the bad news!

Sounds like a couple of coincidental but unrelated symptoms.

Optical cables need precise seating and no tight bends.

Muffled, channel-specific sound is usually on the analog end. Speaker connections maybe.

Both left and right speakers play audio for right speaker


I think you mean the left channel is out but when you use test tone, the sound comes from left and right channels through the right channel speaker. If this is case, the switching IC is malfuncting. Unit needs service
