What means: BEAT CUT ?

tpr - 2007-11-07 05:37

Quoted by Joe Cool:

---------
The frequency of the bias signal applied to the tape during recording of AM broadcasts interfers with the received signal and causes noise. The switch reduces or eliminates this effect. Most bbx models offer at least some form of beat cancel, (with the exception of the most basic), and many offer two or three position switches for this purpose.



1. BC Beat Cancel
2. BC Beat Cut
3. Beat Program (Position 1, 2)
4. BFC Beat Frequency Cancel
5. BFO Beat Frequency Oscillator
6. OSC Oscillator Control
7. RIF Radio Interference Filter
8. BP Beat Proof Function



Regardless of what it's called, (see a.k.a. list) they all perform the same function.

I still dont' understand what this switch does Confused So all it does is make AM recordings sound good? Who the hell records from AM?

Some countries, especially Australia and the USA have programming on the AM band that is considered of value. This typically is talk-based material like talk shows, current affairs or news broadcasts and people may record some of these broadcasts that are relevant to them as part of an electronic scrapbook.

As far as the BEAT CUT switch is concerned, the function of shifting the bias frequency may be achieved by switching between two or three resistance values.

With regards,

It's not JUST for recording, if two AM (MW) stations are on the same freq and causing that 'whistling' sound the switch can often cancel it out. This occurs when one strong station is being slightly affected by a weaker one on the same frequancy.

I seen this switch for years never bothered to learn what is was used for, thanks.

im glad this was posted as i too always wondered what the hell that switch was for. now being a techy i will explain what i read in different terms for those that got lost in the techno speak.

 

pretend you have two cars with the same engine sitting next to each other revving at the same rpm. there will come a point where the sound of the two engines will synch up and you will end up with a third warbling sound as the engines approach the exact same rpm. you following me so far?

 

ok. BIAS is used in tape decks to get the tape setup for proper recording. its basically a low level high frequency tone thats applied to the tape during the recording process. the problem with boomboxes and such is that the frequency they use for BIAS happens to be very close to frequencies used for AM radio stations. mix the two and you get weird effects on your recordings. the beat cut switch offsets the bias frequency in the boombox since you cant do a darn thing about the AM radio stations frequency.

 

if you dont record AM radio you wont have to worry about this.

 

oh and cman750, you know how hard it is to type with that avatar spinning around?
