APPENDIX 4

So you can use Pro Tools LE with the Digi 002 to record, edit, process, mix, and

master your projects in your home studio, then put the Digi 002 under your

arm, take it to a gig, and use it as a digital mixer on-stage. Whoopee! It’s your

 exible friend!

The Digi 002 lies somewhere in that grey area between an entry-level product

and a professional product that is sometimes referred to as ‘prosumer’. It is

de nitely going to give you better audio quality than an Mbox, for example,

but it is not quite in the same league as Digidesign’s TDM systems that o er

much higher quality converters and analogue electronics and much more

choice when it comes to building systems with many inputs and outputs.

Nevertheless, the Digi 002’s analogue inputs and outputs support all the

most important sample rates that you are likely to encounter, with A/D and

D/Aconverters allowing sample rates of 44.1, 48, 88.2, or 96 kHz. The co-axial

S/PDIF connectors support up to 24-bit, 96 kHz audio. If you use the optical

connectors in ADAT mode then these can only support the original 44.1

and 48kHz sample rates that they were designed for. But if you use these in

Optical S/PDIF mode, they will also support the higher sample rates of 88.2

and 96 kHz.

TIP

Don’t forget to select the appropriate I/O format as the Clock Source in

the Hardware Setup dialog when transferring material digitally into Pro

Tools using ADAT or S/PDIF formats.

Rear Panel

The Digi 002 has similar connectors on its rear panel to those on the Digi 002R

(see Figure A4.10 ).

At the lower right-hand side, there are four Microphone Inputs via balanced,

three-conductor XLR connectors. If you are using condenser microphones that

need to take their power from the microphone cables, you can switch on the

48-volt so-called ‘phantom’ power for inputs 1 & 2 or for inputs 3 & 4 using two

small push-button switches located above. This 48-volt power is then supplied

to the microphone via its own cable.

Also located above the microphone inputs, there are four Line/Instrument

Inputs that use balanced, 1/4-inch TRS jacks for line-level or instrument-level
