Line Outputs
By connecting the line outputs of the Scarlett OctoPre Dynamic to the analogue line inputs of a
mixing console (or any other device), the unit can be used either as a purely analogue, 8-channel
microphone pre-amplifier, or as an analogue “break-out box” for ADAT signals when in ADAT
>
LINE
mode.
The line outputs are balanced: for a balanced connection use ¼” 3-pole (TRS) jacks, or ¼” 2-pole (TS)
jacks for an unbalanced connection.
The maximum output signal level is +16 dBu (balanced), or +10 dBu (unbalanced).
Digital Outputs
Use the ADAT OUT optical port(s) [16] to connect the Scarlett OctoPre Dynamic to the ADAT input(s)
of an audio device using TOSLINK optical cable(s).
The right-hand port (as viewed from the rear of the unit) can transmit eight channels of audio at
44.1 kHz or 48 kHz sample rate via a single optical cable.
At 88.2 kHz or 96 kHz sample rates, each port can transmit four channels of audio. The right-hand
port carries Channels 1 to 4, the left-hand port carries Channels 5 to 8; thus two TOSLINK cables
are required to transmit all eight channels.
At 176.4 kHz or 192 kHz sample rates, each port can transmit two channels of audio. The right-hand
port carries Channels 1 and 2, the left-hand port carries Channels 3 and 4. The Scarlett OctoPre
Dynamic is restricted to four channels of digital audio at these sample rates; the outputs of Channels
5 to 8 are not available via the ADAT ports.
Use the SAMPLE RATE switch [9] to select the desired sample rate frequency. It is essential that the
sample rate selected on the Scarlett OctoPre Dynamic matches the sample rate set on the receiving
digital device.
Digital Inputs
Use the ADAT IN optical port(s) [17] if you need to convert digital audio (e.g., the output of a DAW) to
analogue, using the Scarlett OctoPre Dynamic’s ADAT
