Chapter 5: S3 Audio I/O Connections 47
To sum an output to mono:
1 Press and hold Multi-Select/SHIFT.
2 Press the Encoder for the output pair you want to sum to mono. Mono appears in the corresponding display. Mono signals are
sent equally to each physical output in the pair.
3 Repeat to return to stereo operation.
Changing the Monitor Source
You can change the monitor source for the outputs on the S3 using the Monitor Preferences (Mon Prefs) encoder.
To change the monitor source:
1 If necessary, access Audio Control.
2 Under the display showing Mon Prefs, press the encoder Sel switch to select an available monitor source as follows:
AVB 1–2 When AVB 1–2 is selected and appears in the display, Out 1-2 from Pro Tools and Core Audio are routed to Outputs 1–4
on the S3 (and the Headphone output if
MON to HP is selected). This is the default monitor source setting for the S3.
In 1–2 When In 1–2 is selected and appears in the display, Inputs 1–2 on the S3 are routed to Outputs 1–4 on the S3 (and the Head-
phone output if
MON to HP is selected). Use this to monitor an external source such as an audio interface or other playback device.
In 3–4 When In 3–4 is selected and appears in the display, Inputs 3–4 on the S3 are routed to Outputs 1–4 on the S3 (and the Head-
phone output if
MON to HP is selected). Use this to monitor an external source such as an audio interface or other playback device.
Connecting Hardware Inserts
Inputs 3–4 and Outputs 3–4 can be used to insert external hardware on tracks in your application. When inserting hardware, be sure
to connect the device to matching inputs and outputs on S3. For example, to insert a mono device, connect the input of the device
to Output 3 on S3, then connect the output of the device to Input 3 on S3.
Connecting and Adjusting Headphones
Use the front panel Headphone volume control to control overall Headphone volume. By default the stereo Headphone output mir-
rors the other outputs on the S3, but this can be disabled.
To toggle Headphone output mirroring:
1 If necessary, assign I/O controls to Channel Control.
2 Under the display showing Mon Prefs, press the corresponding encoder In switch. When Mon to HP is unlit, the Headphone out-
put no longer mirrors Outputs 1–4.
Mon Prefs encoder and display
In Pro Tools, inserts are defined in the IO Setup. Go to Setup > IO..., then click the Insert tab to define the session insert paths.
