L1 system power consumption and setup distances

I'm interested in knowing about how much power (in watts and/or amps) that an L1 classic (single bass module) system draws from the wall, reproducing just electric guitar and vocals at half max and max output potential for the classic system?

Also, does the new L1 II systems make it possible for the musician to stand closer to his/her system in smaller venues with more consistent sound over the original system? I'm asking because I noticed that the recommended "out front" distance in the new owners manual was less than the original system, for adequate monitoring.

Hi DHurley,

With respect to the recommended "out front" distances - the difference seems to be one of orientation, not distance.

Here is an excerpt from the L1™ Classic Manual



An excerpt from the L1™ Model II Manual

Hi DHurley,

Here's a note about the power consumption:

Same wattage??


The total acoustic output (what matters) of the Classic and model I is functionally identical.

First, this disclaimer: Smile
Wattage can be misleading on an integrated system like the L1(tm). Acoustic output is what matters. As Steve-at-Bose likes to say, 'What's brighter, a 75W incadescent bulb, or a 15W fluorescent?' What matters with lightbulbs is the total brightness, not the power consumtion. Same thing with speakers, the sound output is what matters, not power consumption.

That being said, the wattage of the model I is 500W, as opposed to 750W on the classic. We were able to do this by optimizing the total system design and better matching the amplifiers to the speakers. This is part of the reason that the two systems do not have intecrchangable pieces.

The total wattage on the model II is also 500W. We were able to get the same acoustic output as the Classic with light weight using some cutting edge power amplifiers.

But again, the total acoustic output of the three systems is virtually identical. The model I and II are just more power efficient.

See it in context
Thanks for the info, fellas. The reason I'm asking is because I'm powering my bose system and my hundred watt tube amp through a furman (15 amp max output)voltage regulator. My voltage regulator protects against spikes, sags and brownouts all the way down to 97 volts...the furman boosts power back up to 120.

HOWEVER, if my bose stick and my tube amp together are drawing more than 13 amps, or around 1,500 watts from the wall then it diminishes the regulator's ability to correct line sag. Therefore, I'm really interested in knowing how much the classic L1 draws from the WALL. Not output. The stick is plenty loud enough. Output isn't a problem. I need power consumption. What the stick sucks down to perform at around half cruise and full tilt producing mainly just guitar with one b1 sub. We never run them full volume, but it would still be nice to know.

You mentioned the classic being 750 watts...I'm assuming you mean output power. It's gotta be drawing more than that from the wall. So I'm assuming to at least double that for the draw from the wall. Is one 15amp voltage regulator enough for a classic stick and a 100 watt guitar tube amp?
Dhurley,

For the situation you described, a conservative estimate would have you system consuming about ~~~~600W of power from the wall outlet itself at the peaks.

Im assuming you are talking in terms of how many L1's you could have running on the same 20 amp, 120V outlet. I would not sweat it for up to 3 L1 systems.

MikeZ
To echo Mike-Z, you can budget 5 amps for single system and you can easily run 3 systems of a
typical 15 A circuit.

We do not recommend external voltage regulators because we found that in many cases they cause more harm then help. The amps and power supplies in the L1 use highly efficient switching technology, Many voltage regulators are not a good fit for this technology since they are simply not fast enough.

The L1 is designed to be quite resistant against any AC voltage swings and will operate fine even down at 97 Volts.


Hope that helps

Hilmar
