OctoPre MkII with Analogue Mixing Desk and Digital Record / Backup (44.1 / 48 kHz)
The OctoPre MkII can output to both analogue and digital devices simultaniously. Here the Line outputs connect to the mixing desk
(live monitor), ADAT output 1 to Saffi re PRO 40 (record device), and ADAT 2 to the second Saffi re Pro 40 (record 2 / backup device).
Note that this will work at sample rates of 44.1 and 48kHz.
At 88.2 and 96kHz the two ADAT cables connect to 1 device (4 channels per cable).
