The Clock function, found on Page 14 of Global Edit Mode, determines the sample
clock rate the QSR will use. Normally the QSR uses its own internal clock to
determine the actual number of samples per second. Remember, the sounds in the
QSR are based on digital recordings. These recordings are made up of several
thousands of tiny digital audio “snapshots”, otherwise known as samples. These
samples are played so quickly and run so close together, they all appear to the
human ear to be one sound.
The rate at which samples are played back is determined by the Clock function. It has
four settings: Int48kHz, Int44.1k, Ext48kHz and Ext44.1k. The
default setting is Int48kHz.
When set to either Internal setting, the QSR uses its own internal sample clock as a
reference for playing back the sampled sounds that make up a Program or Mix.
However, if you are recording the QSR to ADAT using the QSR’s [DIGITAL OUT]
connector and the ADAT is using a sample rate of 44.1 kHz, you should set the QSR’s
Clock function to Int44.1k.
If you are recording to an ADAT and also have a BRC Master Remote Controller, the
QSR must receive a clock signal from the BRC in order to maintain perfect sync with
the ADAT system. This requires that you connect a BNC-to-BNC cable between the
BRC’s 48 kHz Clock Out to the QSR’s [48 kHz IN]. When you are ready to record onto
ADAT from the QSR, be sure to set the QSR’s Clock function to either Ext48kHz
(if the BRC is set to 48 kHz) ot Ext44.1k (if the BRC is set to 44.1kHz). By setting
the QSR’s clock to the identical sample rate of the ADAT/BRC, you guarantee perfect
sync between the two units. For more on connecting the BNC-to-BNC cable, see page
