Connect two RCA splitters to both the AUX channels out of your AMP. Connect the existing cable to one of the output of the RCA splitter and connect another pair of RCA cable from the RCA splitter to the subwoofer. I think this is what the guy meant. You can connect either of the below kind of splitter to each channel. You will need two of each
Wholly krapp. I forgot to ask you what amplifier you are using. Sorry.
"We have to use 2 x 1 RCA cable to use the LPF control of the subwoofer. The subwoofer pre-out of your amp will be connected with the line in of your subwoofer." This is what they are saying. I don't follow what they r saying
Your amp doesn't have subwoofer pre-out. But it has recording out which also will function like a subwoofer out with full range of audio output. The easiest is what @sandeepmohan has suggested. Just connect a simple left and right RCA cable pair from the recording out of your amp to the line in of your subwoofer.
I am confused because I have never connected a sub before and the dealer is saying that if you want to use low pass filter function you will have to do this. if the simple RCA cable would do I would much rather prefer that, as it is easily available online. I Apologise if I am repeating myself but I am being extra careful as the dealer said that I have to make sure that everything is okay on day 1 so I need to get the cable before the sub arrives.
Your amp doesn't have a low pass filter to implement a subwoofer out. Yes. the humble and simple RCA cable will do.
The Dealer thinks you are using an AV Receiver. As is mostly the case. Can you tell them that you're using a Stereo Amplifier!
You were right you, even though I told him it was a stereo amp and the brand and everything he was still thinking about AVR. he said normal 2*2 RCA would do just fine
Isn't connecting rec out direct to sub, going to prevent the sub volume from changing when the amp. volume is changed? So every-time amp. volume is changed, sub volume has to be changed correspondingly to keep the balance.
yes. That would happen whether you use the rec out or the RCA splitter method. Ideally there should have been a output after the volume control as a variable pre-out. But unfortunately his amp doesn't have a variable pre-out and his subwoofer doesn't have speaker level input AFAIK.
I think this amp has a headphone output. If the head phone o/p stays on even when the amp. is powering loudspeakers, then you are in luck. You can use a rca splitter at the headphone output and connect 2 rca cables to you sub. That way, as you very the volume on the amp. the corresponding change will happen in the sub., and all frequencies will be balanced. It is not the ideal method, but it may work.
Are you saying its humming/rumbling even without any audio cables connected to the sub? If Yes, the sub woofer is faulty. Send it back and ask the dealer to replace the unit. Or ask the Dealer to come and inspect the unit.
Or his line out has a problem.
Without any cable - no noise. Pin drop silence. Even when I vary the sub volume.
With the RCA cable connected to sub but the other end not connected you will get a hum because your RCA cable is open and hence high impedance. It will catch the 50 Hz mains noise. Have the other end of the RCA cable connected to your source (not the amp REC out). Keep your amp off. If you just get low frequency sounds without any humming, then probably your amp REC out has a noise problem.
The photos were not clear and most probably there is no capacitor on the speaker terminal. A better photo can be found here
He only replace the power cord and did that in front of me. I'll get in touch with Mr Laxman and proceed upon his recommendation to get it rectified with some proficient local electrician or send it to norge. I unfortunately have no skill when it comes to electrical componentsThe photos were not clear and most probably there is no capacitor on the speaker terminal. A better photo can be found here
It is clear from @Shammi Dang photo that your IEC socket doesn't have a fuse. Did the local repair guy replace your IEC socket too?
Since you mentioned that there was lot of sparking happened inside the amp, you better check the connections on the IEC socket. Maybe the repair guy switched the neutral and earth wires. Also the fuse is missing which can save your amp from such miswiring on the socket side. With a multimeter you should check if there is any connection between the phase terminal and earth terminal and also any connection between the neutral terminal and the earth terminal. Show the photo to Laxman from Norge. He should be able to guide to get the amp connection fixed and have a proper IEC socket with fuse fitted there.
