What do the buttons do on my Platinum ADC card (Penta, Trak Master, VoiceMaster Pro, TwinTrak Pro, TrakMaster Pro)? What do I need to press in?

These buttons select the sample frequency. The button on the left swaps between 44.1 and 48 kHz. When the button on the right is pressed in it multiplies the sample frequency selected by two (hence the X2 marking) so now the button on the left swaps between 88.2 and 96KHz. As an example:

For 96KHz - left button out, right button in
For 48KHz - left button out, right button out

Can I stop the Platinum OctoPre from defaulting to the same digital card settings every time I turn it on?

The OctoPre does not have a memory chip in it, so it will always turn on with the same bit rate and sample frequency settings. We advise that the OctoPre is the first thing to be turned on in a studio set-up. Set the freq and bit settings before turning on other gear to avoid noise which could potentially damage monitors.

Pinout for the Platinum OctoPre full-spec AD card

The Pinout for the 9-pin D Sub connector on the OctoPre AD card can be found

Platinum OctoPre LE, where do the connectors go when fitting the ADAT card?

This applies to the legacy OctoPre LE

Please see our Installation Instructions for fitting the card.

This is how the card should look if installed correctly.

Platinum ADC R2 (MH444) card installation problems - what are jumpers and which ones do I remove?

This applies to the Digital Card for the Legacy Platinum Series

The jumpers are small black rectangular clips on the PCB itself. You can remove the top, which leaves two small wires poking up. Removing the jumper breaks the connection at that point in the circuit. There are six jumpers in total:

• J1 - this selects whether the word clock-in is terminated or not. If you are syncing the unit to an external source, and it is the last device in the word clock chain, then J1 should be left fitted. If it is in the middle of a word clock chain, then J1 should be removed for high impedance.
• J2 - this selects whether the S/PDIF output is professional or consumer format. Virtually all pro and home-studio equipment will use professional S/PDIF. Some cheaper CD burners and sound cards use consumer format. J2 should be left fitted for professional formats and removed for consumer formats.
• J3, J4, J5 and J6 - the MH444 A/D card can be used in the Focusrite Penta, TrakMaster, VoiceMaster Pro, TwinTrak Pro and TrakMaster Pro. These jumpers alter the signal level going to the converter, and for use all units apart from the Penta should be removed.

If you cannot find where the jumpers are on the card, then check the picture below. J2 is marked in blue and J3, J4, J5 and J6 are circled in red. J1 is located behind the word clock connector.
