Linking Preamps
Linking preamps allows you to control two preamps simultaneously using one set of preamp
controls. You can match gain controls for two preamps and enable other preamp controls. This is
useful for stereo recording, for example, a microphone pair, stereo synthesiser, or keyboard.
To link preamps:
• Press and hold the Select button for one second.
When you've made the Preamp Link :
• Both preamp numbers light green and the Gain Halos light temporarily to their preamp
level.
• The preamp gain level is set to the lowest value of the newly linked pair.
• The preamp settings are inherited from the currently selected preamp, e.g. preamp 1 is
selected, therefore Preamp 2 inherits, Air, Safe and Inst settings from Preamp 1.
• Changing any preamp setting changes the state for both preamps.
• Adjusting either gain control changes the gain level for both preamps and is shown on
both Gain Halos.
• 48V disables for both preamps.
Unlinking Preamps
To unlink preamps, hold the Select button for one second. When you unlink a pair:
• The first preamp of the previously linked pair becomes selected and lights green.
• Gain levels and preamp settings stay the same, but you can now change them
independently.

48V Button (Phantom Power)
48V, also commonly referred to as 'Phantom Power', sends 48 Volts from your interface's XLR
connector to devices needing power to work. The most common use is sending power to
condenser microphones, but you may also need 48V for inline mic preamps, active dynamic
microphones and active DI boxes.
To turn on 48V:
1. Connect your microphone, or another powered device, to an XLR input on your
interface using an XLR cable. 48V is not sent to the 6.35mm (1/4") jack inputs.
2. Use the Select button to move the controls to the correct input.
3. Turn down that preamp's gain control to avoid any unwanted pops and clicks.
4. Press the 48V button (or the corresponding software button)
The 48V icon lights green to show it is enabled.
48V phantom power is now being sent to the selected XLR input and to any devices connected to
the XLR input.
