B1 is lighter

The B1. The B1 is indeed now a couple of pounds lighter than before. The original B1's had special brackets rated for 'flying' the loudspeakers that were adapted from an earlier product. We now re-did the bracket and made the B1 a couple pounds lighter. The main difference that folks will notice is that handle is now made out of a high strength plastic instead of die cast metal. It is much warmer to the touch for wintertime lugging.

It has the same performance, same drivers, same box, same impedance.

  • Classic B1 is 28 lbs.
  • New B1 is 25.1 lbs.

The new model I manual is indeed incorrect in the new B1 spec. It will be changed...thank you for pointing this out!

Classic / Model I weight approximately the same

Classic vs. L1 model I weight. Both are listed as 35lbs. I made a mistake before by saying the power stand is a 'couple pounds' lighter. In reality it is less than a pound lighter.

Classic / Model I Power Ratings

Input power ratings. These ratings are designated by UL safety standards and in actuality are only loosely related to how the amplifiers actually function.

The UL (USA - 120V,60Hz AC) AC Input power ratings are:

  • Classic : 1400W AC @120V/60Hz
  • model I: 1000W AC @120V/60Hz
  • model II: 500W AC MAX

Our UL Safety fellow here is forwarding me the difference in UL safety ratings and how those specs are arrived at. Again, he stressed it had very little to do with the way the amplifiers actually work.

The max output of the systems is virtually the same.

from Information on new ToneMatch ...

The 1/4" inputs are also balanced, but can be used unbalance as well. So all in all Ch 1,2 & 3 support.

  • Balanced XLR
  • TRS Balanced
  • TS Unbalanced

The TRS and TS inputs are high impedance so you can plug in an acoustic guitar with passive piezo pickup or any other passive instrument directly without a pre-amp.


In other words, it will be hard to find an instrument or microphone that you can't connect directly


Presets

"If a preset from the Classic did not make it into the standard set of a T1™ - it will be available as a download into a ToneMatch™ bank on the T1. We haven't gotten into this much yet, but don't worry, you will be able to access old presets."[1]
