Different output on preciever CES 1020 and preamp CSQ 1020

[Harmony]

According to the manuals of the CES 1020 and CSQ 1020 both apparates have different outputs:

The CES 0,5V and the CSQ 1V

But the manual of the LV720 says the following:

"Ab Werk ist der -pegel-Steller der LV720 auf dem 0dB eingestellt.
In dieser Position ist die Eingangsempfindlichkeit der Eindstufen auf die Ausgangsspannung des Steurerverstarkers Braun CES 1020 oder CSQ 1020 abgestimmt.
Bei Verwendung diese gerate wird die -pegel-Einstellung also unverandert belassen.'

According to the manual of the LV720 0dB means 1V and +3dB means 0,55V

In this way is it correct to set the LV720 -pegel-steller for the preciever CES 1020 on +3dB ??

My setup with the CES 1020 and LV 720 sounds to my ears to soft with the 0dB -pegel- steller on the LV.

The -pegel-Steller of the CES needs now at least +3dB or more to get the right sound stage and volume.

What is your opinion about it?

The same question but in a short way:

Must the pegel-Steller of the LV 720 connected with the CES 1020 set on +3dB instead of 0dB as stated in the user manual?

Don't ask, just do it! If you get "the right sound stage and volume with +3dB", it will be a sound decision to choose this position.

Hi Harmony,

nominal output of CES 1020 is 0,5 V and CSQ 1020 is 1 V, as you wrote.

But you must consider the value of the Input Signal and the Overall amplification. Let me explain:

if you put the Lautstärkeregler of CSQ and CES at the upper most or clockwise right most Position (0 dB) and the Pegelsteller at the 0 dB position too, then the amplification of the CSQ is 12 dB or 4 times and that one of the CES is 3 dB or 1,4 times.

This means if you connect a 1 V signal (from TG 1000 or CE 1020) to the CSQ you get an output of 4 V! The CES would amplify the 1 V just to 1,41 V at the output.

This means that the Output is not limited to what the technical specs say, but some other Parameters (Input level, Pegelsteller) define how high the Output volume will be.

As Simon wrote, set the Pegelregler etc. to that Position that sounds best to you(r ears).

regards,

Raimund

PS: You should perhaps remember the description in the user Manual to set the Maximum Output volume:

Lautstärkeregler set to Maximum, Pegelregler set to Minimum, then you increase the volume with the Pegelsteller to that position, when it sounds a bit too loud. In the future you should change the volume with the Lautstärkeregler only. That´s the theory, but in practice different devices have different Output volumes and you have to adjust again...

Dear Raimund,


"nominal output of CES 1020 is 0,5 V and CSQ 1020 is 1 V, as you wrote"

But the manual of the Braun LV720 says the following:

"Ab Werk ist der -pegel-Steller der LV720 auf dem 0dB eingestellt.
In dieser Position ist die Eingangsempfindlichkeit der Eindstufen auf die Ausgangsspannung des Steurerverstarkers Braun CES 1020 oder CSQ 1020 abgestimmt.
Bei Verwendung diese gerate wird die -pegel-Einstellung also unverandert belassen."

Is this still (technical) correct after your statement?

Hi Joop,

no, it is technical not correct.

I guess for most people who owned either CES or CSQ with LV 720, it didn´t make any difference between the 0,5 or 1 V. Therefore the manual was right for most people who had no technical background and didn´t think about different volumes.

The difference between 0,5 and 1 V is 6 dB, but you should consider that the source signals (or various CDs) differ much more. For example the tuner in CES 1020/Regie 510 is about 10 to 15 dB louder than a tape connected to band or a turntable connected to phono.

As a result if you want to pay attention to the nominal outputs, you should set the Pegelsteller in the LV 720 to + 3 dB for the CES and -3 dB für CSQ.

But I would prefer (and I do it myself) to adjust the maximum level as described in the manual with Lautstärkeregler and Pegelsteller. If a signal is too loud, I decrease with Pegelsteller or vice versa.

FYI: my standard level setting of the Pegelsteller in the CSQ is -6 dB and the LV 720 are set to 0 dB.

Raimund,

"FYI: my standard level setting of the Pegelsteller in the CSQ is -6 dB and the LV 720 are set to 0 dB."

Is this with the pressed Quadro button and the button 'cod. decr.' (SQ decoder) with four LV's?
I can rembember that in this way it sounds a little bit softer with the pressed 'cod.decr.' (SQ decoder)

But actuallly I do only play stereo (with pressed quadro button!) with two speakers.

Mostly my standard level setting of the CSQ Pegelssteller is -12dB with the LV720 set on 0 dB.

Using the CES 1020 I do set now the LV720 Pegelsteller +3dB

Kind regards,

Joop

Simon and Raimund,

I have tried several LV 720 pegel positions and after all I must say that the 0dB position gives the best sound result on the CES 1020.


"Ab Werk ist der -pegel-Steller der LV720 auf dem 0dB eingestellt." is indeed to my opinion the right pegel position

So you have to take the LV 720 usermanual serious.

Thanks for your very useful reactions!
