20. LINE OUTPUTS 1 to 8 – eight balanced analogue line outputs on a 25-pin female D-sub
connector. This connector is always active, and normally carries the outputs of Channels 1
to 8, enabling the Clarett OctoPre to be used as a stand-alone, high quality 8-channel analogue
mic pre. In ADAT
>
LINE mode, the connector carries the signals applied at the OPTICAL IN
ports [19]. The pinout of the connector follows the common “Tascam” standard for 8-channel
analogue interfaces:

21. WORD CLOCK OUT – a BNC connector carrying the Clarett OctoPre’s word clock; this may be
used to synchronise other digital audio equipment forming part of the recording system. The
source of sample clock synchronisation is selected by the SYNC switch [10].
22. WORD CLOCK IN – a BNC connector for the connection of an external word clock signal;
select by setting SYNC to WORD. Use this input if you have a master reference clock which
provides synchronisation for all the digital audio devices in your studio.
23. AC mains – standard IEC receptacle. The Clarett OctoPre is fitted with a “Universal” power
supply, and will run from any AC mains voltage from 100 to 240 V, at 50 or 60 Hz.
