SOURCE: low level noise causing sub flutter

Power wires and sound cables running close together can cause this problem. Separate them.

SOURCE: Auto Sub woofer

There are several causes of distortion in an audio setup.

1) Speaker is unable to handle the frequency that it's being fed
2) The volume is too high for the speaker to handle
3) The amp can't provide enough power to drive the speaker adequately.

Either way distortion is BAD & best to be avoided unless you want an excuse to buy a new set of speakers :P

SOURCE: sub rumbles at very low freq that I cannot raise my output level on the sub

Hello,
That rumble could be several things, start by switching your patch cables to see if there is a fault in the sine. If not it could be the amplifier trying to pull a constant source of current through it to operate and is being corrupted by a fault in the circuitry, or a feed back look of some sort. Either way, if you can't find a problem with your input signal, your sub will need repair or replacement. I hope this helps...

Why is my deck not controlling my subwoofer level?


If your Sony receiver has a separate sub output, it probably has a fixed level for application to a powered sub. Your mono amp can only boost the fixed signal level it receives from your receiver. The receiver can't drive that mono amp harder

Htddw7600, brand new, sub amp is not working, only way to get any bass sound is to unplug the sub cable from back of main amp and touch it on side of sub out port.


H?,
You have a very good system...one of the best of SONY..SUB does not get activated automatically especially on STEREO mode.DIRECT STEREO Notes • No sound will be output from the subwoofer.
.your system has Dedicated Power Amplifier for 2 Externally Driven Sub-Woofers (200W RMS x 2)..in order to activate the sub woofer amplifier you need to make a selection on the surround modes while you are switching the modes of the surround you will see the speaker position on the display of receiver as well..if you do not see the sub woofer it wont be activated..Sound Field Program (A.F.D) is a good example to test it..

Hope this helps!

--------------------
Additionally please follow the instruction on your user manual to activate the SUB ,as is follows..

-----------------
BASS-OUT
Low-frequency (bass) signals can be directed to the
subwoofer and/or the front left and right speakers
according to the characteristics of your system. This
setting also determines the routing of the LFE (low-
frequency effect) signals found in Dolby Digital or DTS
sources.
Choices: SWFR (subwoofer), FRONT, BOTH
• Select SWFR if you connect a subwoofer. LFE and
low-frequency signals from other channels are directed
to the subwoofer according to the speaker settings.
• Select FRONT if you do not use a subwoofer. LFE and
low-frequency signals from other channels are directed
to the front speakers according to the speaker settings
(even if you have previously set the front speakers to
SML).
• Select BOTH if you connect a subwoofer and you want
to output low-frequency signals from front channels to
both the front speakers and subwoofer. LFE and low-
frequency signals from other channels are also directed
to the subwoofer according to the speaker settings. Use
this function to reinforce low-frequency signals using
the subwoofer when playing back sources such as CDs.

Too much bass...low end


Hi, have you tried adjusting the "subwoofer level", and or the "subwoofer cut" controls? Every sub I have ever seen has at least the level control on the back. The "cut or crossover" control determines the frequency at which the sub will start to respond. Additionally, you may need to access the appropriate menu on you reciever and adjust the "low frequency effects" (LFE) output level (assuming you have connected your sub to the reciever's sub output jack.

Hope this helps.

What does sub sonic mean on my Kicker kx1200.1 amp? Do it need to be off or on?


Subsonic refers to frequencies too low for the human ear to hear. Generally humans can hear frequencies in the range of 20 to 20000 hertz (cycles per second), but we hear best in the range of 1000 to 4000 hertz. High amplitude subsonic frequencies can cause damage to your speakers so many amplifiers have an electronic filter in them to reduce the amplitude of these very low frequency signals.

Infinity Bass link keeps cutting out.


Tapping into front or rear gets high level signal 3 plus volts at low impedance which is totally unsuitable for the sub's line level input which is more like 300millivolts > A competent tech could make up an attenuator patch or just take it to a professional car installer before you do more damage

ASW1000 sub bass


Auto sensing circuits function when a certain level of audio output is reached but the transition from off to on can be abrupt, annoyingly so. Another problem is that you may have to set the system volume level higher than you would prefer to get the sub to turn on. I am currently using a sub that does not have this "feature" and performance is more predictable.

can you tell me how your sub is hooked to your amp. is it via the speaker cables or using the amplifier source sub wooker rca connections.
i suppose you have checked all your power cables. if the sub is connected to the amplifier rca output then check the bass sub out level if high enough to drive the auto power switch of sub wfr input. subwoofers normally use an auto power cutoff when no signal. if sub vol level is too low it might not triegger the autopower on.

Very low ouput from subwoofer preout


The problem was that some subwoofers (inluding my velodyne model) cannot process the LFE signals through the line level inputs on its amps, so the other way to run your subwoofer is to run the front left and right speaker outputs from your receiver to the speaker-level inputs on your sub, and then plug your front and left speakers into the soeaker level outputs on the sub. you have to set the onkyo receiver to "Subwoofer: No". that way the LFE signals are sent through the front speaker channels and you will get the same BASS output as if using the line-level input. O So yes it does require a bit more speaker cable, but it works fine now.
