How to Tell the Difference Between L1 Models

This is how to tell which L1® unit you have.


 
2020 - Present L1 Pro8, L1 Pro16, L1 Pro32
2020 - Present Sub module for L1 Pro32
2018 - Present 4 channel ToneMatch Mixer (stereo)
2018 - Present 8 channel ToneMatch Mixer (stereo)
2018 - Present Extremely Portable PA Battery powered
2015 - Present Flexible Array Loudspeaker and Subwoofer

2003 - 2007 Classic30.pngRounded front. The Output Panel has Amp1 Out, Amp2 Out, Amp3 Out

Signal/OL LEDs: Channels 1 and 2

SignalOLLED.png

There are two LEDs on the PS1 Power Stand (Classic) / Model I near the Trim knob labelled Signal/OL -- one for Channel 1 and another for Channel 2.

These LEDs indicate when the signal level channel's preamplifier reaches certain important thresholds. The trim controls located near the LEDs adjust the amount of gain in the preamplifier.

The LEDs turn from off → green when the signal level exceeds a small amount.
The LEDs turn from green → red when the signal reaches a level that's about 10 dB below a level that would clip the preamp and cause objectionable distortion.

When the LED is off (but you are playing an instrument you think is connected to the PS1 or singing/talking into a microphone you think is connected): Increase the level of the trim control. If the LED still does not turn green or red, check instrument/microphone and cables to the PS1.

When you see green only: This indicates that there's some signal in the channel but not enough. While singing or playing the loudest you ever plan to in the performance, increase the trim level until the LED is only flickering red. This is the optimal gain.

When you see red most of the time: Decrease the trim level until you see only flickering red. This is the optimal gain.


Phantom Power LEDs: Channels 1 and 2

Phantom Power LED and Switch

The LEDs near the Phantom Power button are either off or red when phantom power is turned on. — more information about Phantom Power

Power / System Status LED

This LED normally is a steady green when the power is on.

Power LED

If it is not lit or if it is yellow/amber, contact Support.

Note: This LED may briefly flicker yellow /amber when the power is first turned on; this is normal. Within a couple of seconds, it should settle to a steady green.


Leaving it in the bag

It is okay to do this if you like (and personally I find it a lot quicker for setup/teardown)

Heat

Hilmar-at-Bose speaks about the heat [1]

The PS1 does have fans, but they are only kicking in when you work the system pretty hard. The power amps are very efficient, and a nice side effect of high efficiency, is that there is a lot less heat to get rid off. So unless you are hitting it very hard, the fans will be off and at that kind of volume level, the fans are pretty much inaudible.

Leaving the system inside the bag is perfectly fine. The vents are above the mixer section and if the bag is open enough so you an insert any cables, than its also open enough to get appropriate ventilation.

If possible you should avoid exposing the PS1 (or any kind of electronics for that matter) to direct blazing sunlight. That can generate enormous amounts of heat inside the system to the point where it actually has to shut down (to protect some of the internal components). As a general rule, if it's too hot for you as the performer, than it's probably also too hot for the system. Finding a little shade will certainly help in a scenario like this.

Access Door / Flip Up Panel

Cliff-at-Bose talks about the door [2]

"I took my cover off right away and couldn't even tell you where it is right now. The carry bag for the PS1 seems to do a good job of keeping things clean in storage, the trunk, in transit. For the upper L1 section, turn it upside down, grab it by the bayonet, lower it into the bag and the bayonet should tuck into the top just fine.

Cover Unused Inputs

To avoid mishaps at a gig cover or plug the unused inputs on your PS1 Powerstand. This picture shows white nylon caps in the lesser used inputs of a L1 Classic Powerstand. The L1 Model I does not have the inputs in the white area near the top right.

Look down the well - Thanks to Joseph for this one [3]

Set up my Bose as usual just before an early gig tonight and except for the sub-woofer (B1 Bass Module), there wasn't any sound coming out from the line array when plugging in the guitar directly (without the usual PODxt Live in front of it).

Whool! I was definitely started to freak... I surely didn't want to pull my van around again and have to get out the Roland Keyboard back-up amp.

The anguish I was going through just imagining having to use anything other then the Bose was excruciating.. to think that I might have to play the next run of back to back gigs (five of 'em to be exact) without my baby Bose...:-(

Trouble shooting all possibilities, nothing-nada was happening ... no beauteous guitar sound whatsoever!...

The one thing I did notice however, was that the pole was wobbling just a tiny bit. Whenever I would take it apart and put it back together again, there seemed to be the slightest, almost imperceptible of wobbles.

Finally, after taking it apart and putting it back together again for the third time I looked into the power base (PS1 Power Stand (Classic) / Model I) fitting and saw one of my picks lying there. Sure 'nuff... the pick was blocking the connection. This thin little pick was just enough to prevent the Bose from making full contact.

So be forewarned guitarists ... stray picks can be a threat to your total Bose sound fulfillment.

Battery Power

Hilmar-at-Bose tells use that battery power is not recommended [4]

A sufficiently sized generator will work with our system although they tend to be fairly noisy.

Car battery converters (so called "inverters") are a little problematic. Most inverters don't work well with our highly-efficient Switch Mode Power Supplies and need to be 2 to 3 times oversized. That draws really big amounts of current from the car battery and the wiring from the battery to the inverter needs to be able to handle that. This is by no means a trivial job, so we recommend against it.
