Apollo x8 Hardware Manual Rear Panel 28
Analog I/O
Apollo x8 rear panel (analog portion)
(34) Line Outputs 1 – 8
The individually addressable line-level analog outputs use balanced ¼” TRS phone
jacks. Unbalanced ¼” TS cables can also be used. The Line Outputs are DC coupled.
Line Output Headroom
By default, the operating level of the line outputs is +20 dBu. The line
outputs and inputs can be globally configured to operate at +24 dBu
signal levels with the HEADROOM menu in the Settings>Hardware
panel within the Console application.
+24 dBu operation is typically used for interfacing with professional
audio equipment such as large format consoles, analog tape machines,
and similar devices that require higher signal levels. For additional
details about +24 dBu operation, see the Apollo Software Manual.
Line Output Reference Levels
The Line Outputs can be configured in adjacent pairs to use either –10 dBV or +4 dBu
reference levels. This function is configured in the Hardware panel within the Console
Settings window. See the Apollo Software Manual for details.
ALT Outputs 1 – 4
Apollo x8 features ALT (alternate) monitoring capabilities. ALT monitoring can be used to
control up to two alternate pairs of monitor speakers.
When ALT monitoring is enabled, the output level and muting of line outputs 1 & 2
(ALT 1) and 3 & 4 (ALT 2) are controlled by the Monitor Level & Mute knob (#23). ALT
monitoring is enabled in the Hardware panel within the Console Settings window by
increasing the ALT COUNT setting to a non-zero value.
