Abs; Meter; D/A Input; Mdm In - Apogee PSX-100 Operating Manual

If the D/A input is AES, D/A INPUT will show AES1 and AES2 illuminated, indicating that 'double wide' AES
format is expected (see 96 kHz AES format table). S/PDIF is inactive for these rates (Note: S/PDIF A/D outputs
at 44.1/48 kHz – every other sample – in FAST mode). If the video card is installed, the system automatically
generates 88.2 or 96 kHz sample rates from video inputs. Press & Hold again to exit FAST mode.

OUTPUT RES

Hold this button down DURING POWER-UP until the power-on display stops to reset the PSX-100 to the fac-
tory defaults (except DIP switches). Otherwise the last-used settings will be recalled.

ABS

If the ABS LED is already lit, Press & Hold to turn on ABS processing for the AES outputs and indicate this by
flashing the ABS LED. Remember, the ABS LED must be lit prior to Press & Hold to enable ABS for the AES out-
puts. Press & hold again to turn off ABS for the AES outputs, the LED will stop blinking to indicate ABS for the
AES outs is off. NOTE: DIP Switch 8 controls ABS on AES INPUTS. At 88.2/96kHz sample rates, ABS is not avail-
able on the AES inputs and outputs as both connectors are used.

METER

Clears clip indications. Clips are held indefinitely unless DIP Switch 2 is set to ON (2 second hold). See DIP
switches.

D/A INPUT

Enters analog monitor mode (see OPERATION). Press & Hold again to return to confidence monitor mode.
If you try to access analog monitor mode while already in digital copy mode, DIG COPY will blink, indicating
that you must return to confidence monitoring mode first.

MDM IN

ABS processing on MDM inputs. LEDs 1-2 and 3-4 will light up. You can then toggle to 5-6 and 7-8 by briefly
pressing the MDM IN button. Press & Hold again to return to simple 1-2. Not valid for 88.2/96K operation.

SOFT LIM

Press & Hold to enter CAL mode ("meter zoom"). The SOFT LIM LED will blink. See Calibration under exter-
nal settings.
MUTE L, R
If the optional Video Sync Module is installed and "VIDEO" is selected as the A/D SYNC, pressing and hold-
ing the L or R button "pulls up" (multiplies) or "pulls down" (divides) the sample rate by 1.001 respectively.

DIG COPY

In Digital Copy mode, the output of the interface used for digital input is normally muted to avoid feedback (eg
you can't copy from S/PDIF to S/PDIF). Press & Hold DIG COPY to enable Loop Mute Bypass. The LED flashes.
In this mode, all digital outputs are active – use with care to avoid feedback. To re-establish muting, exit Digital
Copy mode or Press & Hold DIG COPY again.

Indicators

AD SYNC LEDs
Indicates the source to which the 'main clock' (i.e., the clock of the A/D converter) is synchronized. When on
DIG IN, the particular digital source to which the clock is locked is indicated at DA INPUT.
NOTES:
• DIG IN will normally be indicated when the PSX-100 is in Digital Copy mode. An exception is when doing a
digital copy from TDIF, during which WC will be indicated (DIP switch 1 ON – LRCK).
• A/D sync will skip VIDEO in the toggling cycle unless the optional card is installed.
• ERROR simply means loss of lock. It has been Apogee's experience that CRC checking should not be
employed because some digital sources do not encode it properly, leading to false errors.
x2Fs LED
Indicates that the entire system is running in 'FAST' mode (i.e. at 88.2 or 96 kHz sample rates).
