You are “confident” that the signal on tape is OK because you’re listening to the return of the recording

device instead of the straight feed from the A/D converter. Keep in mind that some recorders do not have a

confidence monitoring feature, in which case, you will not actually be monitoring the signal off the tape itself

but rather the signal straight through the recording device. Check with the corresponding manual or manufac-

turer to see whether or not your recorder supports confidence monitoring. The lack of a confidence monitor-

ing mode will not affect the functionality of the PSX-100; that is, the PSX’s D/A will play back whatever is fed

to it.

In Confidence Monitor mode, the A/D section and D/A section are independent of each other – just like

having separate A/D and D/A converter boxes sitting side by side. For example, the A/D section can be clocked

from the internal CRYSTAL at a 48 kHz sampling rate feeding your ADAT while the D/A section is receiving dig-

ital audio from your CD player at 44.1 kHz. The diagram on the previous page shows the PSX in a typical record-

ing application.

To verify that the unit is in confidence monitor mode, the ‘A/D OUT’ LED under the heading ‘D/A INPUT’

and the DCOPY light should not be illuminated.

2. The second mode is

ANALOG MONITOR MODE, where the A/D input is routed to all digital outputs

(including AUX out) as well as the D/A output. This differs from confidence monitor mode in that the feed from

the A/D converter is routed directly to the input of the D/A converter. So what you’re monitoring is not the

return from the recorder as in confidence monitor mode: instead it’s the output directly from the A/D. Below is

a typical recording application using analog monitor mode.

While mixing, for example, it is often convenient to be able to listen to the mix through the A/D and D/A

so you know exactly how it will sound when it is laid to tape (e.g., hear the result of the A/D conversion, Soft

Limit, UV22HR, etc). In Analog Monitor mode, you can do this while not tying up your mixdown deck (i.e., hav-

ing it constantly in record through mode). You can switch between analog monitor mode and confidence mon-

itor mode to compare the direct signal to the signal coming from ‘tape’ (or disc, etc).

To enter this mode, press and hold the ‘D/A INPUT’ button. The ‘A/D OUT’ LED will light (under the head-

ing D/A INPUT) to indicate that the unit has entered ANALOG MONITOR mode.
