OPTIONAL DIGITAL CONVERTER FRONT PANEL
CONTROLS
CLOCK (non-latching switch)
This switch is used to select the digital clock source. Pressing the switch steps through
the five available sources: Internal crystal (running at 44.1kHz or 48kHz), an external
Word clock source (input on rear panel), an external 256x clock source (input on rear
panel) or the clock embedded within the incoming ADAT
panel). The green LEDs indicate the currently selected clock source.
ADC LOCK (LED)
This LED indicates that the internal A/D chips are correctly synchronised to the
external clock signal entering the rear panel Word clock BNC connector (if Word clock
or 256x are selected) or ADAT
input (if ADAT
with synchronisation then the ADC LOCK LED will fail to light and the
corresponding CLOCK LED will flash. When a Lock is achieved, the ADC LOCK
LED, the selected CLOCK SOURCE and, if an external source is selected, the sample
rate LED will all illuminate.

ADAT
IN (Optical 'lightpipe' connector)
This connector allows an ADAT -type multi-channel digital signal to be fed to the
digital to analogue converter and then on to the Line outputs on the rear panel, if
selected by the relevant switches (see below), for up to 7.1 surround monitoring.
ADAT
OUT (Optical 'lightpipe' connector)
This connector transmits the recorded signals in ADAT -type multi-channel digital
format for sending directly to the DAW or other recording medium. This output can
be used to send all eight of the OctoPre LE's analogue input channels for recording,
whilst simultaneously using the ADAT
WORD CLOCK IN (BNC connector)
This connector provides an input for either an external Word clock or 256x clock
source, from which the OctoPre LE's optional A/D chip can be set to synchronise (see
CLOCK section in OPTIONAL DIGITAL CONVERTER FRONT PANEL
CONTROLS). For further advice on synchronisation in digital setups, refer to the
support section at www.focusrite.com.
WORD CLOCK OUT (BNC connector)
This connector provides a word clock signal from the optional converter card, so that
the OctoPre LE can be the master clock from which another ('slave') device or devices
can be synchronised. If the OctoPre LE is synchronised to an external source and the
ADC Lock is illuminated, the Word clock output will transmit a clock at the sample
rate indicated on the front panel (44.1kHz, 48kHz or 256x if that mode is selected),
from which further devices can be slaved. For further advice on synchronisation in
digital setups, refer to the support section at www.focusrite.com.
DAC TO LINE OUT (Switches)
Since the OctoPre LE can act as a monitoring control for outputs sent digitally from
the DAW or other recording medium, the ADAT
balanced 1/4" jack Line outputs on the rear panel. There are two switches to allow this;
1-4 sends channels 1-4 of the incoming ADAT
5-8 sends channels 5-8 of the incoming ADAT
With both switches engaged, all eight channels of the incoming ADAT
sent to the Line outputs, for 7.1 surround monitoring or analogue subgroup mixing for
example. In this case, the digital ADAT
