| − | The {{T1}} comes with a really nice Pro Ethercon cable, with robust metal connector shells and an almost memoryless 18' black cable.
| |
| − | | |
| − | However, in a pinch, should you forget the cable, or if say a huge Hammond B3 gets dropped on the cable and severs it, YOU CAN USE ANY ORDINARY CAT 5 ETHERNET CABLE and it will work fine until you replace you nice fancy T1 cable.

| − | Later in that discussion Hilmar-at-Bose tells us:
| |
| − | | |
| − | Any CAT5 (or CAT5e, CAT6, or CAT7) cable will work just fine without any degradation at least initially. The downsides are that most ethernet cables don't coil particularly well and that the connectors wear out over time. After a a few hundred uses you may notice the occasional drop out, at which point it's time to get a new one.
| |
| − | | |
| − | It's certainly a quick and cheap way to get a spare for an emergency.

| |
| − |
| |
| − | A 33 or 50 footer will not cause any problems, either with the digital audio (ones and zips) or the power.
| |
| − |
| |
| − | The technical reason follows, for those who are interested : A 24 gauge wire (the size typically used in ethernet cables) has about 2.5 Ohms of resistance per 100 feet. The T1 draws roughly 1/4 Amp on each of two supply wire pairs (+/-18V nominal).
| |
| − |
| |
| − | For a 50 foot run, each pair of wires (made up of a plus and minus lead) totals 100 feet. A quarter Amp of current across 2.5 Ohms gives, per Ohm's law, a voltage drop of less than one volt (V=IR = 0.625 Volts). Because of the margin we built into the system, it can handle this voltage drop easily.
| |
| − |
| |
| − | In fact, although we don't recommend it and can't guarantee it, the digital audio has been tested up to 100 feet in average conditions (for example, no undervoltage on the AC supply at the gig), and quite happily continued to make music.

| − |
| |
| − | Bill at Bose stated you could run 50' of ethernet cable no problem at all. Success at distances longer than that would start to depend on outside factors, for instance the voltage of your power source.
| |
| − |
| |
| − | Another option for you is to run the {{T1}} off of the optional power supply, and then run a balanced line from the Master Out on the {{T1}} to the balanced 'analog input' on the {{Model II}}. This method would be able to transmit over a hundred feet, perhaps much more.

In 23 years at Bose, the L1 Model II and T1 ToneMatch Audio Engine are the most lovingly designed products I have ever had the fortune to work on. More care by more experienced people went into this than anything I've been involved in.
The most minute details were studiously created. As one tiny but important example, a propriety light pipe was designed so that the light from volume knob indicators smoothly wrapped around the knob from top to side, giving the musician a clear indication of volume from any angle.
