| − | == Gain Staging ==
| |
| − | | |
| − | 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.
| |
| − | | |
| − | [[Image:T1TrimPots.png|T1® Trim Pots]]
| |
| − | | |
| − | === Set Up Your Source ===
| |
| − | Set your source at the maximum that it will be when performing.
| |
| − | * Microphone
| |
| − | :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.
| |
| − | * Instrument
| |
| − | :Turn your input as high as it is likely to go during performance.
| |
| − | | |
| − | === Set Input Trim ===
| |
| − | 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).
| |
| − | | |
| − | [[Image:TrimlightsOK.gif]]
| |
| − | | |
| − | 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 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.
| |
| − | | |
| − | :If the T1 trim is going red, you should back off, you are definitely nearing or in compression.
| |
| − | | |
| − | :A really helpful feature on the T1 is to go to the Prefs/Output Level menu, and see where you are relative to maximum output.

| − | 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]
| |
| − | | |
| − | Channels 1,2,3 support
| |
| − | | |
| − | *Balanced XLR
| |
| − | *Unbalanced Tip-Sleeve
| |
| − | | |
| − | 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.
| |
| − | | |
| − | :Choosing the "best" input impedance is a little bit of a trade off and matching the pickup's impedance is not necessarily the best choice.
| |
| − | | |
| − | *Piezo pickups are also somewhat of a capacitor and together with the input impedance of the preamp, this forms a low pass filter.
| |
| − | *If the impedance is too low, then the low pass filter is in the audible range and the guitar looses sparkle and gets a little dull.
| |
| − | *If the impedance is too high, the system gets noisy and somewhat sensitive and finicky. For example, stepping on or simply moving a cable changes it's capacitance which creates clearly audible artifacts with a very high input impedance.
| |
| − | *We feel, that 1 MOhm is a very good compromise for a life application.

| |
| − | | |
| − | *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.

We have a recommended trim setting for connecting the T1 to a {{Model I nl}} input Ch 3 or Ch 4
| |
| − | | |
| − | Note: New recommendation is '''3''' see below.
| |
| − | | |
| − | With this setting you will not distort or clip the Model 1 no matter what you do on the T1. You can even use the Model 1 without the remote.
| |
| − | | |
| − | The {{T1}} controls are a heck of a lot faster then the R1 controls. There is no perceivable lag.

| |
| − | | |
| − | For these conditions:
| |
| − | {{Classic icon}}{{Model I icon}}
| |
| − | * {{T1 nl}} going into {{Model I nl}}/{{Classic nl}} into Channel 3/4
| |
| − | * Balanced OR Unbalanced 1/4" cable
| |
| − | * {{Remote}} unplugged, OR, master volume on {{Remote}} at 12 o clock
| |
| − | * Proper gain staging required on the T1® itself
| |
| − | | |
| − | I'm going to revise the original recommendation of '''2''' for Ch 3/4 to '''3''' - under the above conditions.
| |
| − | | |
| − | This will give you the same gain going into the {{Model I nl}}/{{Classic nl}} as if you were going through the [[ToneMatch® Cable|ToneMatch®]] input on a {{Model II}}.
| |
| − | | |
| − | If you are using the {{Remote}} on your {{Model I nl}}/{{Classic nl}}, then you will need to compensate a bit. If you running the {{Remote}} master volume at max, then stick with '''2''' on Ch 3/4. I would recommend against running the master volume below 12 o'clock when using a T1®.

| |
| − | | |
| − | Without getting too deep into technical stuff, with regards to the T1 the two ways to interface with a {{Model I}} are:
| |
| − | | |
| − | 1.) The way we generally recommend - 1/4" out from the T1 into Ch 3/4 with the Level at '''4'''.
| |
| − | | |
| − | 2.) 1/4" balanced {{TRS}} from the T1 to XLR input of Ch 1/2. Of course this requires a TRS to XLR cable which most folks don't have lying around - but is a common studio connector available at GC etc.
| |
| − | | |
| − | Both ways are equal as long as your distance from the model I is less than 25 or 30 feet. Longer than that I would lean toward option #2.Method #1 allows you not to use a preset Channel on the model I.

| |
| − |
| |
| − | ... (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.
| |
| − |
| |
| − | Functionally they are basically the same in terms of frequency response, input impedance, noise performance, max gains etc.
| |
| − |
| |
| − | 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.

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>
