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

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.

 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.
