Drawmer DMS-5 M-Clock Plus AES Grade 1 Master Clock / Dual Sample Rate Conv. - Manual (Page 7)

7
MODE With the sample rate set to EXT 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 192kHz.
±PPM
Displays the nominal sample rate with +/- ppm (part
per million) error indication for 32, 44.1, 48, 88.2, 96 &
192KHz.
±%
Displays the nominal sample rate with percentage pull
up/down indication for 32, 44.1, 48, 88.2, 88.2, 96 &
192KHz
MASTER CLOCK GENERATOR
SAMPLE RATE
The outgoing sample rate for all outputs of the DMS-5 can be set using the two sample rate
switches - the left moving down rate and the right moving up, with a corresponding LED being lit to
show the current sample rate. The DSM-5 generates six Ultra Low Jitter sample rates - 44.1k, 48k,
88.2k, 96k, 176.4k and 192k, all stable to <1ppm, and in addition can also operate at the sample
rate generated by an external source.
EXT SOURCE With the Sample Rate set to EXT the EXT SOURCE switch
toggles between either AES or Wordclock (as located on the
rear panel). As with the “Source” section a lock LED is
provided on the front and operates when the EXT clock signal
is strong.
