ich habe den Ausgang der Bose L1 compact verwendet, um das Signal über Cinch Out auf eine HiFi-Anlage zu geben. Die Bose war so eingestellt, dass beim Line In die grüne LED Dauerlicht hatte.

Das Signal war so schwach, dass die HiFi-Anlage mit Maximalpegel gerade mal eben so zu hören war. Sollte in einer Seniorenfreizeitstätte einen 2. Raum ergänzend beschallen, aber reichte nur, um eine in der Nähe sitzende Person zu nerven.

Als ich mit der Bose L1 compact über den Klinkenausgang eine weitere Anlage speiste, musste ich diese auch weit aufdrehen, damit sie ungefähr gleich laut ist.

Gleichzeitig erinnere ich mich daran, dass ich schon mal die Bose mit ihrem Ausgang an einen Verstärker anschloss und dort nicht den Eindruck hatte, diesen besonders aufdrehen zu müssen.

Nun meine Frage, ist es normal oder ist es ein Defekt? Hatte ja diese Funktion nie genutzt und nie ausprobiert und komme eigentlich auch gut klar damit, wenn der Ausgang ein schwaches Signal liefert.

Hi Ronny,

I'm sorry I can't reply to you in German.

Let me check in with you. Are you using a splitter cable from the Bose L1® Compact 1/4" LINE OUT to connect to the HiFi system?

That probably won't work.

You should have better results with a cable like this.

I hope that I've understood your post correctly.

Best regards,

It was so, that I used a twin cable with RCA cinch on both sides to feed the HiFi system and the RCA cinch output. Level was so low, that it began to be audible, when I turned the volume on the HiFi to maximum volume.

When I did another test, I used a mono 1/4" jack, like the cables used for electric guitars, had to set the volume of the other sound system much much higher, than needed with line level from a CD player.

In both cases, Bose L1 compact's level was so, that the green LED was permanent on.

I remember, that years before I plugged Bose's output to a powered speaker and hadn't to set the volume much higher.

It's important for me to know, is something wrong with my Bose. I made the failure, no to test the outputs after getting back from service.

HI Ronny,
I read your first post too quickly. I thought you were connecting from a Bose T1® (not an L1® Compact). I have corrected my reply above.

If I'm understanding you correctly, you connected the L1® Compact to the HiFi.

using a cable like this

Is that correct?

What input were you using on the HiFi?

I know it and when I had set Bose L1 compact's level so, that the green LED may flash, instead being nearly permanent, I would understand, that the output level is pretty low.

But I thought, that the RCA cinch levels would be standarized.

I remember the 5 pin DIN connectors, now used for MIDI, where radio's recording output has a lower level, than tape's playback output.

The HiFi was a unit with CD, radio and amp and I used it's tape input. 

Later I tested another sound system (LD Systems MAUI 5) and used Bose's RCA out and MAUI's RCA in and after this Bose's jack out and MAUI's jack in and noticed, that the level was low, compared with another source.

It differs to my last application some years before, where Bose L1's output level seemed to be normal to the little powered speaker's line in.

Hi Ronny,

On the recording devices I have used, there has been input level control. 

I have only seen a few HiFi sets that have an input sensitivity control. Does yours have one?

I think the output may be higher if you use the 1/4" output if you use a cable like this.

It's too late here for me to turn up my L1® Compact right now. I can try some tests tomorrow.

Hi Ronny,

I did some testing and it sounds like you and I are having a similar results.

I connected my L1® Compact RCA Line Outs to a HiFi system. The output level is relatively low unless I turn up the volume on the Compact all the way up. The output of the L1® Compact Line Outs is controlled by the volume control. 

I think both of our L1® Compacts are operating as they were engineered to perform..


Ich werde noch mal die Aussage von ST auf deutsch zusammenfassen.

Bei der Bose L1 compact, ist der Pegel, der am Klinkenausgang anliegt, abhängig von den Lautstärkeeinstellungen, beim Cinch-Ausgang nicht. Aber es ist normal, dass beide Ausgänge ein schwächeres Signal haben und man bei nachfolgenden Geräten weiter aufdrehen muss, also kein Defekt.

Eine normale HiFi-Anlage zu speisen, dürfte nicht so gut gehen, man bräuchte einen Aufholverstärker oder müsste es an einen eventuell vorhandenen Mikrofon-Eingang anschließen.

Bei anderen Anlagen gibt es eine gewisse Flexibilität.

Hi Ronny,

Thank you for doing the translation in German. Someday, when I master the guitar and singing,  and then all things related to music, sound, and acoustics, I will learn German.

Google translate tells me your post says.

I will summarize again the statement of ST in German.

With the Bose L1 compact, the level that is applied to the jack output depends on the volume settings, the RCA output is not. But it is normal that both outputs have a weaker signal and you have to turn on further devices, thus no defect.

A normal hi-fi system to dine, should not go so well, you need a catch-up amplifier or would have to connect it to a possible microphone input.

For other plants, there is a certain flexibility.

If Google is correct then I would re-write this part

With the Bose L1 compact, the level that is applied to the jack output and the RCA output depends on the volume settings.

It is important to understand: The L1® Compact channel volume controls affect the signal sent to both the jack output and the RCA outputs.

When you turn the L1 Compact channel volume UP, the signal at the jack output and the RCA outputs goes UP too.

Does that help? Maybe Google got it wrong.


Ich hatte vorher ST wohl falsch verstanden, darum bat er mich, es noch mal zu ändern.

Bei der Bose L1 compact, ist der Pegel, der am Klinkenausgang und Cinch-Ausgang anliegt, immer abhängig von den Lautstärkeeinstellungen beider Kanäle.  Aber es ist normal, dass beide Ausgänge ein schwächeres Signal haben und man bei nachfolgenden Geräten weiter aufdrehen muss, also kein Defekt.

Bei Geräten aus dem Beschallungsbereich, wie Aktivboxen, Akkulautsprechern und ähnlichem ist der niedrige Ausgangspegel meist kein Problem, es gibt genug Leistungsreserve.

Die meisten Aufnahmegeräte dürften auch mit diesem niedrigen Pegel noch klar kommen.

Aber eine normale HiFi-Anlage dürfte mit diesem Pegel Mühe haben, ein hörbares Signal von sich zu geben, man müsste wohl einen kleineren Aufholverstärker oder Booster zwischen schalten oder es an einen eventuell vorhandenen Mikrofon-Eingang anschließen.

And now in English again.

I missunderstood ST, so he asked me, to change my statement.

On Bose L1 compact the level on jack and cinch output depends to the volume setting on both inputs. It is normal, that the level on both outputs is pretty low and you have by the following units to set volume much higher, this is no malfunction.

When you use units made for live music and PA, like powered speakers, mobile battery speakers and comparable, the low output level is in most cases no problem, there is enough capacity.

Also most recorders may manage this low level.

But a usual consumer HiFi system is challenged, to play an audible sound signal, so you may need a booster or to use microphone inputs if available.

I am surprised, that Google translate did well in this case. Usually, Google translate has much problems, when languages are related, because German and English are Germanic languages.

But the main question is answered, my system works fine, it's not a bug, it's intention and when I know it, I can manage it easily.
