Pro Tools | Carbon Front Panel Operation
14
24 DIM button — Press to dim (attenuate) the signal level of the selected monitor set by the amount (in dB) configured in the Pro Tools
Hardware Setup (see Main Page). The default Dim value is –15 dB. When enabled, the button lights amber. When disabled, the button
lights white.
DIM does not apply to Headphone outputs.
25 Headphone outputs 1–4 (stereo 1/4-inch).
Configuring Inputs
You can select the input (microphone, line, or instrument) and configure the input settings for channels 1–8 (front panel instrument in-
puts or back panel mic/line inputs) on the front panel of Carbon.
To select the input source for any analog input channel:
1 Press the Input Encoder (7) to cycle though and select any of input channels 1–8 as the source.
2 Press the INPT button (10) to select MIC (back panel), LINE (back panel), or INST (front panel, input channels 1–2 only) for the se-
lected channel.
To adjust the input gain for any analog input channel:
1 Press the Input Encoder (7) to cycle though input channels 1–8 and select the desired channel you want to adjust.
2 Turn the encoder (7) to boost or attenuate the input gain for the selected channel.
To link (or unlink) input channels:
1 Press the Input Encoder (7) to cycle though input channels 1–8 and select one of the channels you want in the linked pair. Input chan-
nels can only be linked in adjacent odd and even pairs (1 and 2, 3 and 4, 5 and 6, or 7 and 8).
2 Press the LINK button (9) so that it is lit (linked) or so that it is unlit (unlinked).
The selected input channel and its neighbor are linked. For example, if you selected input channel 3, channels 3 and 4 are linked; or if
you selected input channel 8, channels 7 and 8 are linked.
To select the impedance for Instrument input channels 1–2:
1 Press the Input Encoder (7) to cycle though and select input channel 1 or 2.
2 Ensure that the selected input channel is set to INST.
3 Press the Z button (11) to cycle through and select the desired impedance for the selected channel.
To select the impedance for the selected MIC input channel (channels 5–8 only):
1 Press the Input Encoder (7) to cycle though and select an input channel (5–8 only).
2 Ensure that the selected input channel is set to MIC.
3 Press the Z button (11) to cycle through and select the desired impedance for the selected channel.
To switch polarity for the selected input channel (1–8):
1 Press the Input Encoder (7) to cycle though and select an input channel.
2 Press the Ø button (12) to toggle polarity for the selected channel.
To enable phantom power for the selected input channel:
1 Press the Input Encoder (7) to cycle though and select an input channel.
2 Ensure that the selected input channel is set to MIC and that an XLR cable is plugged into the physical input.
3 Press the 48V button (13) to toggle phantom power on and off for the selected channel.
INST is only available if a 1/4-inch cable is connected to the corresponding INST input jack on the front panel.
It is not possible to adjust input gain for LINE inputs if the preamp gain is bypassed for that input (see Line Input Gain).
It is expected to have higher input gain levels with higher impedance settings.
