My amp turns on good but after a while of too much bass causes a ugly sound too loud what could it be? Can it be repaired?


If you have over driven the amp by playing it real loud with the bass control turned up, it is very possible that you have toasted the output stages of amp.
Every time you boost a tone control by 3 db you have doubled the output power at that frequency. So if you are "coasting" along at a nominal 75 watts, the moment you boost the bass by 3 db the amp has to put out 150 watts at that low frequency.. Go to +6db and now the poor amp has to kick out 300 watts! And so on.

Rule of thumb - you never use your tone controls at very loud levels. Tone controls are there to compensate for the poor frequency response of the human ear at low volume levels - the Fletcher Munsen effect. At low volumes our hearing with the lows and high frequencies so when you play something at low volume you boost up the bass and treble to compensate for poor hearing. At loud volumes our ears respond properly.

Sound bass


Laptops are notorious for poor sound performance, the issue is the speakers used on any laptop are not big enough to convey the deep rich bass some users require.

A workaround to this is to buy a good set of headphones when utilizing the sound system on a laptop.

Otherwise you need a better quality laptop; Some are made with premium sound speakers but again they too are limited due to the speaker sizes used in laptops. Not to mention the cost of getting one of these types of laptops.

I'm not quite satisfied with color and black tone. What settings would you recommend.


You do not say what exact model of printer you are using so any answer will be generic rather than specific.

Poor colour and black tone can be as a result of various factors:
1. Poor paper quality that you are printing on.
2. Poor ink or toner quality being used.
3. Use of Ink / Toner saving modes or software.
4. Worn or damaged printer components such as the fuser roll on a laser printer and other similar consumables with a limited page use life.
5. Poor quality content being printed, i.e. low quality images being printed at too high a print resolution.

In most of the Amplifiers we have only Bass and Treble control (Bass works on 100 HZ and Treble works on 10KHz - approximately). In some Amplifiers we have Mid range control also. What is the frequency...


The frequency of mid range control is about 1KHz. The bass and treble are usually enough to set the tone of sounds and music, and if the customer has high quality speakers connected to the amplifier it is almost unnecessary to modify any tone. In my opinion you are right that x-band equalizer became less important now.
Thank you.

My Video ipod has poor quality sound. Kinda lacks bass.


If you've messed with the EQ settings and it still sounds horrible you may want to have the jack/hold switch assembly replaced. You can get a jack/hold switch assembly on eBay for around $7 for your model of iPod.

GETTING BETTER SOUND QUALITY


An equaliser is, put simply, a more complex tone control, giving you the ability to cut or boost more specific frequencies than a tone knob, or bass & treble controls.

It comes in handy for tweaking the sound from your hi-fi to just the way you like it. But beware, as it can make your hi-fi produce sounds that are so bass or treble heavy, that you can damage your speakers if you're not careful.

Adding another compnent into the chain (like a graphic EQ) can add a little background noise but this Technics EQ is a pretty quiet one & you probably won't notice the noise apart from when there's no music playing & you've got the amp turned up high.
