(f) LINK
Links input channels 1 and 2 as a stereo pair. When linked, preamp control adjustments 
are applied to both channels. 
Note: Only the same type of inputs can be linked (Mic+Mic or Line+Line). The 
Hi-Z input cannot be linked to a Mic or Line input.
Monitor Options 
When in MONITOR Mode, the Option Buttons control the monitor options (described 
as g – h below). Press the MONITOR button (11) to enter Monitor mode and enable the 
monitor options.
A monitor option is active when its indicator in the lower row of the Options Display 
(12) is lit, and inactive when the indicator is dim. If the indicator is unlit, the option is 
unavailable.
The TALK, DIM, ALT, and FCN functions are configured in the companion Console 
software application. See the Apollo Software Manual for details.
Note: In Preamp mode, the monitor options cannot be modified and the lower row 
of the Options Display is unlit.
