    Re: Few Beolab Penta -questions

    Ville Laustela:

    4) Without having a BM7000 I think it will be quite good enough! Cool

     

    I ask this question because I will use BM7000 to drive Penta 1.

    Yesterday, I heard Penta 1, that was driven by Beomaster 6000 as pre-amp, that connected though line-in connection and play by CDP Wadia 850, about 3000$. The sound is very disappointed. And I don't think a speaker like Penta can produce such a terrible sound like that. The sound quality from my Beovox S45-2 driven by Beomaster 2400 is much better, in comparison.

    I am wondering. DO the sound quality change if Penta 1 drived by BM7000?

    Hello everbody,

    I have a problem. I have just bought a Beolab Penta 1, that driven by Beomaster 7000. Connection by 2-pin DIN. After half an hour for listenning, I found that a beolab power amplifier is so hot. another one is normal and cool. Anyone know why and how to solve it?

    I dont know whats wrong with your Penta 1s but I recall I never got my Penta 1 to run relaiable on normal 2-pin DIN. Worked as a charm on 4-pin DIN (called Speakerlink, or a older version of Powerlink). Also used Line Input (normal screened RCA) but that was on a BM5500 wich had pre-amp output. Think you need a special plug for BM7000 to get pre-amp output. 

    Cheers

    Actuallty, there is no problem on connection using both 2-pin, 4-pin speaker link and line-in. The problem I have met is after 5-10 minute playing, the power amplifier on Penta 1 become hot. I think there is problem with some transitor. Anyone can help me?

    Worth pointing out that Penta 1 runs with different cross-over values to Penta 2 and some additional components.

    It may be that for Penta 2 they sorted the mid-range issue. Certainly my Penta 1's are not as bright or accurate as my RL140's. They still have a more fuller sound.

    I'm hoping to pick some cross-over boards from a Penta 2/3 for comparison if anyone has any?

    Re: Few Beolab Penta -questions

    Apologies on looking at the service manual for Penta 2 I can confirm the crossovers changed for Penta 3. I'm working out these changes now so will post in a different thread. The boards are compat so it's simply a case of removing a few components and replacing a few others. It looks like the inductors remained the same. Phew. :)
