There are few technical issues which is very common we found in Marantz PM 6007 that we will discuss here:-
Overheating of Main-amplifier
The defensive circuit is initiated if the temperature of the main amplifier segment transcends a specific level, which can occur on the off chance that the intensifier is ceaselessly utilized with over the top sign stream being input into it. The defensive circuit is additionally enacted when the set working temperature is surpassed, which can occur on the off chance that the vents on top of the speaker are covered, or on the other hand if the enhancer is introduced on a confined sound rack. In these cases, the MUTE pointer in the focal point of the board streaks, and the volume is consequently diminished. Around 15 seconds after the fact, the defensive circuit is delivered, thusly the volume needs correcting to proceed with ordinary use.
In the event that the temperature doesn’t adequately bring down inside a certain measure of time after the defensive circuit actuation, the power turns Down and the STANDBY marker over the POWER ON/OFF button streaks.
In the Event of Amplifier Trouble
The defensive circuit is enacted and the power is naturally shut Down assuming an irregularity is recognized in the power circuit. The equivalent occurs assuming the primary breaker inside the intensifier blows. In these cases, the STANDBY marker over the POWER ON/OFF button streaks.
If excessive ultra-bass signals are input
The defensive circuit is likewise actuated if super bass signals that surpass the base sign reach settings are input.. For this situation, the MUTE pointer in the focal point of the board streaks, and the volume is consequently decreased. Around 15 seconds afterward, the defensive circuit is delivered, in this manner the volume needs correcting to proceed with typical use. If inordinate ultra bass signal info proceeds or on the other hand assuming DC voltage is distinguished due to issue with the speaker, the power stop and the Backup pointer over the POWER ON/OFF button streaks.
In the Event of Overcurrent
The defensive circuit is initiated assuming that current surpassing a certain level is distinguished, which can occur assuming extreme sign stream is contribution to the intensifier or on the other hand assuming the PM7001 is associated with a speaker arrangement of under 4 ohms impedance. The defensive circuit is likewise actuated assuming a speaker link shorts. In these cases, the MUTE pointer in the focal point of the board streaks, and the volume is naturally diminished. Around after 15 seconds the defensive circuit is delivered, subsequently the volume needs rearranging to proceed with typical use. Also, if the overcurrent proceeds, the intensifier’s power stop and the STANDBY marker over the POWER ON/OFF button streaks.
No sound from the centre or surround speakers
The most well-known reason you can’t hear any sound on the middle speaker is that you are playing sound system content. Naturally, most surround sound frameworks will just play sound system sound on the front left and right speakers. To utilize the middle speaker with sound system sound, you should empower an upmixing sound mode on your amplifier like Dolby Surround or DTS Neural:X.
Renewal the automatic setup routine: Most AV receivers have a programmed speaker arrangement process. Go to the setup menu for your gadget and run the routine once more. This will make sure that you have every one of the right speakers associated – and it will generally send a test tone to everyone. On the off chance that you get sound in the middle now, you know the wiring and config are OK, and the issue lies somewhere else.
Ensure the audio is surround sound: In the event that you are playing satisfied with a sound system soundtrack, you will not hear a single thing from the middle speaker. This is likely the most widely recognized justification for hearing nothing from the middle speaker. Play a film that is in 5.1, and check whether you hear anything now
