CONTROL DESCRIPTION

DISPLAY A Blue/White LCD display wth three switchable modes of operation: FREQ, ±PPM and ±%.

The mode that is displayed during power down is saved for the next session.

The display accuracy is 2ppm at all sample rates up to 768kHz, or 0.1Hz increments @

48KHz sample rate

MODE A switch controls the mode of display enabling you to read the incoming sample rate in your

preferred manner. Pressing the switch toggles through the three modes of FREQ, ±PPM and

±%, with led indication.

FREQ

Displays the actual frequency to four decimal

places upto >768kHz.

±PPM

Displays the nominal sample rate with +/- ppm

(part per million) error indication for 32, 44.1, 48,

96 & 192KHz

±%

Displays the nominal sample rate with percentage

pull up/down indication for 32, 44.1, 48, 96 &

192KHz

INPUT SOURCE CLOCK PRESENT

Sets the input source

to be used - either AES

or BNC as connected

on the rear panel - with

led indication.

The two LED’s indicate the status of the input

sources. When a led is lit continously a strong

signal is being recieved by that input source and

the D-Clock is “locked on”. If a led flickers, the

signal for that particular input source is weak or

unstable - in this case the source of this weak

signal should be located and improved.
