Too much bass

No.
The RP-280F is just a passive floor standing speaker.
Passive means it does not produce any type of audio/sound itself. It must be powered by an external amplifier or other source of power outside from itself.
Therefore it cannot/does not adjust or modify the power & or frequencies provided by another product.
Usally your adjustments for bass & treble are located on the receiver/amplifier/stereo/whatever your power source is & is adjusted by the product that is producing the power.
Hope this helps.

The record deck is played through a separate pre-amp to all other functions, so it therefore could be a fault in that pre-amp, but I doubt it. You can fit a wide verity of cartridges in record decks that will each give a different response to the sound. But first check that the cartridge connections are correct. Try swapping them around, it might change what you get. But it could simply be that you have a cartridge that produces a lot of bass. Changing the cartridge to a high quality recommended type - by say some hi-fi buffs website or magazine, might solve the problem.

I've got the same problem. When you put therecord on, spin it from the centre, and it will release the mechanism inside,this is what I do, and it works fine. I think the problem is that there are twoplates under the turntable, and there was grease between them, after a few goesthe grease disappears, causing the problem.

Please make 100% certain the needle is still in place... To test this *GENTLY* rub your fingertip over it and you should hear noise from the speakers when you do. If there is NO noise then there is likely no needle.
Did you put the protective device on the needle/arm for the move? Is it still on there?
Sorry Mate, that the only thing I've got to help....

There could be several reasons why your Fender 25R amps are not producing the tone you expect. Here are a few things to check:

1. Make sure the tone controls are not bypassed: Some amps have a switch that bypasses the tone controls. Check the manual or look for a switch on the amp to make sure the tone controls are engaged.
2. Check the speaker: If the speaker is damaged or wired incorrectly, it can affect the tone. Try connecting a different speaker to the amp to see if the tone improves.
3. Check the EQ circuit: There could be a problem with the EQ circuit that is preventing the tone controls from working properly. This would require opening up the amp and checking the circuit with a multimeter.
4. Try using different guitars: Different guitars have different tone characteristics, and some may sound better with different settings on the amp. Try using different guitars to see if the tone improves.

If none of these solutions work, you may need to take the amps to a professional technician for further diagnosis and repair.

READ your quick start booklet. You need to go to control panel, open sound, there are three tabs- choose playback and make sure that the selected speaker is not USB Audio Codec-choose your speakers. In the Record Tab selcect USB Audio Codec.

As you probably know, the Bose 901 Active EQ is there to modify the frequency spectrum fed to the 901's so they will produce a flat response. Without it, they sound acceptable in the midrange but lacking in bass. Since they have no woofers or tweeters, the modification is drastic and should never be applied to non-Bose-901 speakers or they could be damaged.

This setup should work for mixing and playing but I'm not sure if recordings directly from the unit's REC Out or Line Out would have the Active EQ effect on them. You'll need to perform a few tests to see how it all works for playback AND recording.

Remove the jumpers for Pre In >> Out

Insert the Active EQ in their place by running:

1. RCA cables from Pre Out to the Active EQ In (From Aux, Tape Out)
2. RCA cables from the Active EQ Out (To Amp, Tape In)

Use ONLY 901's on this amp with the EQ.

The Bose Active EQ has its own Tape Rec/Monitor loop to replace the one it normally occupies in a typical receiver application, so if you wish to record your mix you should use those connectors for your tape deck and there will be no problems with the Active EQ effect being recorded. The Monitor Tape/Source switch on the EQ functions just like a typical Tape Monitor. For playback of the recording, switch it to Tape.

The manual, available at http://lib.store.yahoo.net/lib/acekaraoke/MA3000K.pdf
doesn't get into any detail on the innards of the mixer.

In a typical integrated amp or receiver, the jumpers removed are between the Preamp Output and the Main Amp input, but BEFORE the amp's volume and tone controls, so manipulating them would not affect a recording. You should experiment with it by making recordings through both and adjusting speaker volume to see if it changes.

I would be curious to know what the functional difference is between the designated LINE Out, REC Out and PRE Out jacks in that regard. Normally, Line Out and REC Out will not vary with amp volume, but I expect in this mixer it does, or you wouldn't be able to control the volume from it. Experiment.

Of course, you probably want the mixed effects to be recordable, so I assume they'll appear at all outputs. Play back the test recording (at an initial low level, just in case) and see if you can detect an exaggerated low end (due to the 901 bass boost being applied in recording AND playback through the 901's. If the recording volume doesn't vary with speaker volume and the playback sounds as flat as the recording you're good to go.

If there is are volume variations or an additive effect, you may have to draw the REC Out to the deck's input and run the deck's output to the Tape In on the 901 Active EQ, monitoring only on deck playback.

If you can't hear the difference maybe the bass frequency which is moving the speakers is below your hearing range.

I think you may have a "loudness" button on that amp -- if you do, turn off the loudness -- this is a bass booster.

But, in general, bass speakers are designed to move in & out a lot. They have to move a lot of air to produce the bass sound.

The transport screw is just for stabilising the suspension for moving the turntable. Just put it in the position that allows the turntable to bound up and down a bit when you poke it.

As for the skating of the tonearm, it's just that the tracking force is set too high. I don't know your turntable, so can't tell you quite where the tracking force adjustment is, but it's likely a dial close to where the tone arm pivots. A test record (with test tones) is a great way to adjust that, but otherwise repeated listening to a record will help you - make sure that the loud parts of a track distort equally on both speakers.

Could be a bad patch cord, a setting on the mixer, a faulty mixer (unless it works ok with other amps), or a dirty control on the Sony amp if it has analog controls. Have you tried connecting other sources to the Sony?
