(21) Line Outputs 1 – 16

The 16 analog outputs are accessed via dual female DB25 connectors. Each DB25 jack

carries eight balanced line-level channel outputs using standardized Tascam wiring. The

Line Outputs are DC coupled.

Note: See DB25 Wiring for connector pinouts.

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 Thunderbolt 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. Refer to the Apollo Software Manual for details.

ALT Outputs 1 – 4

Apollo x16 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 (#12). ALT

monitoring is enabled in the Hardware panel within the Console Settings window by

increasing the ALT COUNT setting to a non-zero value.
