The behavior of the bass line out and B1 Bass Module outputs on the {{Classic}} and {{Model I}} are based on the philosophy that adding {{B1}}s should give the user more dynamic range (can play louder) but should not alter the tone of the instrument, including tone adjustments made using the {{R1}}, the {{T1}} or other tone-shaping equipment.

:What happens when you select a channel ‘Bypass’ button on the T1® audio engine?
  
This philosophy is notably different from other manufacturers, who take the approach that it's okay (or desirable) that adding more bass speakers causes the instrument tone to become "bassier".
+
:Pressing the ‘Bypass’ button on a channel will change it’s current ToneMatch® preset to the generic “Utility Flat” preset. This enables you to audition between specific ToneMatch® presets and the ‘Utility Flat’ setting, helping you decide which preset you will ultimately choose.
  
With this philosophy in mind, here is how the bass line out and B1 outputs work.
+
:In contrast, the key frequency adjustments for [[zEQ]] do not change when the ToneMatch® preset is ‘Bypassed’. For instance say that you originally had a ‘Kick Drum’ preset selected and then pressed ‘Bypass’, the key [[zEQ]] adjustment points would still remain focused on fine tuning a kick drum.
  
=== No cable plugged into the Bass Line out ===
 
* If there is 1 x B1 connected to the B1 Bass Module output on the PS1: B1 EQ, bass signal gain = REFERENCE LEVEL
 
* If there are 2 x B1 connected to the B1 Bass Module output: B1 EQ, bass signal gain = REFERENCE LEVEL - 6 dB
 
  
Why? Because when you add a second B1, if you did not change the signal strength you would get 6 dB more bass relative to the mids and highs. This would alter the tone of the instrument. To keep the tone the same, while still allowing the more dynamic range (system can play louder by 6 dB) the signal level must be reduced by 6 dB.

** If you are using  a {{A1 EB}} this is a total of 3 B1s (2 on the A1 and 1 on the PS1)
 
* If there are 2 x B1 connected to B1 Bass Module output on the PS1: B1 EQ on Bass Line Out and B1 Out, bass signal gain = REFERENCE LEVEL - 12 dB

The PS1 does not measure the exact number of {{A1}}s, so there is a slight error if you use anything but 1,2, or 4 B1s.

Introduction to Bypass

Hi Folks,

At the recent L1 users conference in Colorado, we found out that a high percentage of T1 owners did not know about the BYPASS feature that's employed in many places in the T1.

The BYPASS feature is extremely useful in deciding if a particular adjustment is giving you the sound you want. It's a form of an A/B switch.

For example, if you want to hear how a particular ToneMatch preset sound on and off, you would use bypass. If you wanted to hear how a particular reverb sounded you could turn it on and off, on and off. And so on. Most effects have this valuable feature.

As an example, here's the screen after you've chosen a Tonematch preset for Channel 1. In this case, I've chosen the preset for an Audix OM5.

What Happens When You Bypass a Preset?

What happens when you select a channel ‘Bypass’ button on the T1® audio engine?
Pressing the ‘Bypass’ button on a channel will change it’s current ToneMatch® preset to the generic “Utility Flat” preset. This enables you to audition between specific ToneMatch® presets and the ‘Utility Flat’ setting, helping you decide which preset you will ultimately choose.
In contrast, the key frequency adjustments for zEQ do not change when the ToneMatch® preset is ‘Bypassed’. For instance say that you originally had a ‘Kick Drum’ preset selected and then pressed ‘Bypass’, the key zEQ adjustment points would still remain focused on fine tuning a kick drum.
