=== In the Box ===

 

Your first adjustment for any input to your {{T1}} is the Trim setting. The exact position of the Trim will vary depending on signal strength of your input source. The correct setting for any particular source may be different from your other sources.

 

 

Set your source at the maximum that it will be when performing.

:Sing directly into the microphone using close microphone technique (lips just brushing the windscreen). Sing as loudly as you will sing during your performance. You want to set the Trim to work at your maximum volume.

 

{{T1 Gain Microphone}}

 

:Turn your input as high as it is likely to go during performance.

 

Turn the Trim setting up until the Trim Light is solid green with occasional flickers of yellow. Use the Trim lights as your guide. (The exact position of the Trim knob is not important).

 

 

If you see flickers of red (below), turn the Trim down. You are definitely nearing or in compression. Turn the Trim down until there are no red flickers.

:One difference in gain staging the T1 and the Classic is that the T1 has a three-stage trim LED. It lights up green when a signal is present, yellow when you are getting pretty loud (8 to 10 dB of headroom left), and red when you dangerously close to or at full scale.  

:In a way, the yellow trim on the T1 is similar to how you treat the red on the Classic. Some yellow during peaks is good on the T1, just like some red on the Classic is good.

 

 

 

 

== Inputs ==

 

 

The following notes about Channels 1,2,3, 4/5 are from Hilmar-at-Bose spread out over several posts in [http://bose.infopop.cc/eve/forums/a/tpc/f/7521050644/m/5031050644?r=2981027944#2981027944 Information on the new T1 ToneMatch audio engine]  

 

The Tip-Sleeve 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. Input impedance on Channels 1,2,3 is about 1 MOhm. Channels 4 and 5 have an input impedance of about 10 kOhm.  

 

[http://bose.infopop.cc/eve/forums/a/tpc/f/7521050644/m/5031050644?r=7571094084#7571094084 Bill-at-Bose gives us the following insights into Channels 1,2,3 and 4/5]  

*For inputs 1-3, you can physically plug a TS or TRS 1/4" plug into the jack, and get perfect fidelity.  

*If you have a balanced line source and TRS cable, and plug into an unbalanced input (1,2,3), you may not get as much resistance to induced noise or potential ground loop hum as you will if you plug into the balanced inputs (4,5).  

*Our Master and Aux outputs are actually balanced, so you will have an advantage on noise if you use a TRS, but they accept a TS also. So there we also wrote that they "accept" both TS and TRS.

MikeZ-at-Bose tells us:<ref>MikeZ-at-Bose [http://bose.infopop.cc/eve/forums/a/tpc/f/7521050644/m/3651093054?r=1711028154#1711028154 talks about the preamps in the L1 Model I and the T1® ]</ref>

... (the preamps on the Model I are)... exactly the same as the Classic.

On the {{T1}} they're different, but are designed to the same standard as the {{Classic}} preamps.

The difference comes in how we get there. I'll try not to go into horribly boring detail. The name of the game is trade-offs, and in the end the design constraints dictate the *best* type of circuit used for *this* particular situation. Here are a couple of the many factors that dictate the differences:

Gain structure. The internal components of the {{T1}} are different that the {{Model I}} / {{Classic}} and need to have signals fed to them in certain ways. Different designs are more suited to the levels needed than others.  

Physical layout of the circuit on the board. There are four channels in a tighter space in the {{T1}}. Again, certain designs lend themselves to be better at this than others.  

After evaluating all of the factors that go into the design of a preamp we are using another proven circuit that relies more on discrete transistors rather than op-amps. It fits our needs better for this design situation. The preamp design itself is not necessarily any better or worse. There are *many* ways to skin the cat of preamp design to achieve a desired performance.  

Will it sound different? No...I certainly cannot hear a difference playing through it. Can't measure one either.  

Hope this sheds some light on it.

Here are the specifications for the Model I Preamps.

This means that these are post-trim, and nothing else (e.g. Muting) has any effect on the signal at the preamp outs.

5 foot of cord from the T1 to the switching power supply, and a removable 6 foot cord from the power supply to the wall. This is very similar to a laptop power supply.

Q: Please talk about using the {{T1}} outdoors. Will I be able to see /read the display? A: Should be no problem. The LCD display on the T1 is "transflexive". In dark conditions the blue backlight will shine through the "transmissible" part so everything is easily visible. In bright sunlight, it becomes "reflexive" just like a piece of paper. The backlight may wash out (i.e. it will not look really blue anymore) but it's still clearly visible. <ref>Hilmar-at-Bose talks about the [http://bose.infopop.cc/eve/forums/a/tpc/f/7521050644/m/5031050644?r=4091059454#4091059454 transflexive display on the T1®]</ref>
