Drawmer DMS-1 M-Clock Master Clock Generator and Multiple Sample Rate Converter - Manual (Page 8)

8
The Drawmer M-Clock supplies word clock, S/PDIF, AES 11
grade 1, as well as Digidesign’s superclock (256x) allowing
you to synchronize Digidesign Pro Tools™, and a host of
other digital audio equipment through one stable and very
accurate unit.
The M-clock provides a wide range of sample rates from
44.1k upto 192k, as well as Superclock, all set using the front
MASTER CLOCK GENERATOR
OUTPUT SAMPLE RATE The sample rate of the the unit is set using a combination of two switches, with the
resulting sample rate indicated by the corresponding led’s.
RATE The RATE switch sets the base rate - either 44.1k, when the switch is out, or 48k, when in.
Hi (x2) The Hi (x2) switch doubles the sample rate that is set by the RATE switch. i.e RATE is set to
48k (pressed in), Hi (x2) is pressed in - the resulting output sample rate is 96k.
The following output sample rates can be achieved:
RATE switch position Hi (x2) switch position Result
Out Out 44.1 kHz
In Out 48 kHz
Out In 88.2 kHz
In In 96 kHz
CLOCK OUTPUT OPTIONS
5/6 The 5/6 switch affects only connectors 5 and 6 on the BNC Clock Outputs on the rear of the
panel, working independantly from the other outputs, and can provide a maximum output
sample rate of 192k.
When pressed in the sample rate that is set by the RATE and Hi (x2) switches is doubled
i.e. Rate/Hi (x2) set the sample rate to 48k (Rate in/Hi out) - with 5/6 switch pressed in the
sample rate at the BNC output 5 and 6 is doubled to 96k even though the other outputs on
the M-Clock are still 48k. This would allow the user to have a workstation working at 48k
whilst similtaneously recording a DVD quality backup.
Output Sample Rate 5/6 Switched IN (x2)
44.1 kHz 88.2 kHz
48 kHz 96 kHz
88.2 kHz 176.4 kHz
96 kHz 192 kHz
panel switching. In addition upto three different sample rates
can be output at the rear of the unit, simultaneously, i.e. 96k
output from Word Clock outputs 1 to 4, 192k output from 5
and 6, and 256x superclock from 7 and 8. This feature allows,
for example, a DVD quality backup to be made whilst working
on Pro Tools™ simultaneously, making studio
synchronization easier than ever before.
