S/PDIF Mirroring

Pro Tools LE uses S/PDIF mirroring to automatically “mirror” the audio that is sent to 
outputs 1 and 2 on the S/PDIF RCA outputs. This is useful if you are monitoring a mix using 
your audio outputs, and also recording the same source to an external S/PDIF device.

You can disable this S/PDIF mirroring. You might do this if you wanted to use the S/PDIF 
outs to send a separate signal to an external digital effects unit, or if you wanted to send 
only certain outputs to the digital device. If you disable S/PDIF mirroring you are able to 
select the S/PDIF outputs separately, and route tracks or sends to them.

To enable or disable S/PDIF mirroring:

1  

Choose Setups > Playback Engine.

2  

Click Other Options.

3  

Select or deselect the option “Enable S/PDIF Mirroring.”

Connecting Audio Sources

To connect an analog audio source:

■

Plug a microphone directly into Mic/Line Input 1 or 2 on the front of the Digi 001 I/O 

Box. These inputs accept XLR connectors or 1/4" TRS connectors. If your microphone re-
quires phantom power, press the Phantom Power switch (labeled 48V).

▲

Although phantom power can be used safely with most microphones, ribbon mi-
crophones can be destroyed by it. You should always turn off phantom power, 
and wait for the red light to go completely off, before connecting a ribbon micro-
phone.

■

Plug line-level sources (synths, outputs from your mixer, or microphones or guitars that 

have been amplified by an outboard preamp) into the analog inputs on the back of the 
Digi 001 I/O Box.
