== Introduction ==

{{Classic}} is the name now used to describe the ~~original L1®,~~ introduced in the United States, in October 2003.

{{Classic}} is the name now used to describe the first {{L1 CR}} introduced in the United States, in October 2003.

The Classic remained in production until 2007 when it was replaced by the {{Model I}}.

Visually and acoustically the L1 Classic is almost identical to the Model I, with only a few notable differences.

~~Visually and acoustically~~ the L1 Classic ~~is almost identical~~ to the Model I.

==Comparison of the Classic to the Model I==

~~Here are~~ the ~~main differences:~~

* [[PS1 Powerstand Connections|PS1 Power Stand Connections]]

** On the right side of the input/output panel, there are inputs for

*** All Amps In

*** Amp 1 In

*** Amp 2 In

*** Amp 3 In

** There are outputs

*** Amp 1 Out

*** Amp 2 Out

*** Amp 3 Out (used for {{B1}}s)

** Features above support accessing the three amplifiers separately. One application is to drive up to six {{B1}}s from a single Power Stand. See: [[Classic Extended Bass Package]]

* Units that were shipped with the Version 2 [[Presets/Model I and Classic|Presets]] have a blue ring around the Amp 3 output (for {{B1}}s).

~~This is the Input Panel as it appeared in~~ 2003~~-5. Units that look like this were shipped with [[Presets 1.0]] installed. An upgrade to [[Presets 2 Upgrade instructions|Presets Version 2.0]] is available~~ and ~~highly recommended.~~

===PS1 Power Stand Connections===

{{Classic}} '''shipped between 2003 and 2005'''

[[~~Image:ClassicIOPanel1.png~~]]

The L1 Classic had features built into its input/output panel that allowed the three amplifiers to be used separately as power amplifiers. For example, up to six {{B1}}s could be driven from an auxiliary Power Stand. See: [[Classic Extended Bass Package]]

~~In 2006 the Input Panel had a blue background for the B1 connection. These~~ units ~~were~~ shipped ~~with Presets 2.0 preinstalled~~.

The input/output panel as it appeared in units shipped between 2003 and 2005 is shown.

'''Model I'''

:~~Hi Folks,~~

The {{Model I}} uses a simpler input/output panel

* Dropped Amp 1 out, Amp 2 output found on the {{Classic}}

* Identified by orange labels and {{L1 no link}} logo

* [http://en.wikipedia.org/wiki/RoHS RoHS] compliant.

* Shipped with [[Presets 3.0]] installed.

~~:Here and in a few other areas, there's been a good discussion about volume levels in the L1 classic vs the Model II.~~

:I ~~think there are two separate issues:~~

[[Image:ModelI-whole-I-O-panel.png|800px]]

~~:# How LOUD can the Model II play vs~~. ~~the Classic or the Model I?~~

~~:# If you set trim and channel volumes on the T1 similarly to the Classic, will you hear the same sound level?~~

~~:As to Question 1, The Model II system plays as loud as the Classic or the Model I. Moreover, the Model II is no more or less susceptible to microphone feedback than the Classic of the Model I.~~

:Question 2 is being answered thoroughly in other threads. My take is that the Model II and the Classic are two different products in the same family. There are some differences in how the gain staging is done. The best course in my opinion is on both units to set the trim levels and leave those alone, then use channel and master gain to bring the level to the desired amount. Again, there's no difference in the maximum sound levels.
