13. Digital Inputs
Three digital coax and 3 TOSLINK optical digital
inputs are provided for connection of legacy
digital sources.
14. Analog Input
Eight RCA inputs are provided and can be used
as 4 stereo pairs or 1 7.1 input. When connected
as a 7.1 input, the channel assignment is as follows
clockwise from top left: LF, CF, LS, LB, RB, RS,
SUB, RF.
15. Amplified Analog Output
Twelve amplified outputs are available to drive
your speakers, being rated 4 or 8 ohms. Astral 16
integrates three individual power supplies each
driving 4 channels (1 to 4, 5 to 8 and 9 to 12). In
order to avoid too early current limit protection, it
is recommended to carefully map the outputs so
that Left, Center and Right speakers are charging
a single power supply module each (such as Left
on ch1, Center on ch 5 and Right on ch9). See
"Output Mapping".
16. Downmix Output
A stereo pair of XLR outputs is provided as a
dedicated 2 channel downmix output. These
outputs produce a stereo downmix of whatever
audio is playing in the selected theater. To
configure, see "Parameters". Downmix may be
enabled for select presets. See "Presets". Pin 2
hot.

17. Amplifier Ventilation
Two electronically thermally regulated FANs are
used to cool down Astral 16 amplifier section.
They will work from time to time depending on
the overall output current load. Do not obstruct
the fan or any airflow vents on the chassis and
the front panel.
18. Analog Output
Four XLR analog audio outputs are provided
which are fully assignable to theaters or zones.
See instructions starting with "Building a Theater
- Defining Channels". Outputs may also be
remapped. See "Output Mapping". Pin 2 hot.
19. Processor Fan
From time to time, Astral 16 may automatically
turn on the Processor fan to draw cool air through
Astral 16. Do not obstruct the fan or any airflow
vents on the chassis.
