003 Family Setup Guide76
When connecting to a stereo system, connect 
the left channel to Main Monitor Output L, and 
right channel to Main Monitor Output R.
Main Monitor Outputs L and R play the audio 
that is routed to analog outputs 1 and 2 within 
Pro Tools. 
The Monitor Level knob (located on the top 
panel of 003, and on the front panel of 003 Rack 
and 003 Rack+) adjusts the volume level of the 
Monitor Outputs. 
You can also connect a sound system to any of 
the Analog Outputs 1–8, although you will not 
have Monitor section controls available.
Mirroring the Outputs on S/PDIF Out
When using your 003 family interface with 
Pro Tools, you can send any pair of outputs 
(such as outputs 1–2) to the S/PDIF digital out-
puts at the same time by assigning the stereo 
mix to multiple output destinations. This is 
commonly known as mirroring the outputs.
Output mirroring is useful for recording to mul-
tiple media, creating separate monitoring mixes, 
or for output to digital effects processors.
To mirror 003 family interface Outputs 1–2 on the 
S/PDIF outputs: 
1 Open the Pro Tools session whose channel 
outputs you want to mirror. 
2 In the Mix window, click the Output selector 
of any audio or Auxiliary Input track to select 
the main output destination, for example, Ana-
log 1–2. 
3 Control-click (Mac) or Start-click (Windows) 
the same Output selector and select an addi-
tional output pair from the same pop-up menu.
The newly selected destination is indicated by 
an additional check mark in the output pop-up 
menu, and a plus sign in the Output selector.
Monitor Outputs (all models)
Home stereo systems often use RCA 
connectors for analog audio connec-
tions. You can use an adaptor or a spe-
cial cable to convert from the TRS or 
TS connectors used by and 003 Rack to 
the RCA connectors on your home ste-
reo.
If you plan on connecting Analog Outputs 
1–8 to –10 dBV gear, you may want to 
place a transformer-based line level attenu-
ator between your 003 family interface’s 
output and the input of the destination de-
vice to compensate for level differences.
