CS1D Operating Manual (Basic Operation)

MIX buses/MATRIX buses

The PM1D system can send the input channel signals to MIX buses 1–48. The signals sent to a MIX bus is routed
through a MIX channel that provides EQ, comp, and delay, and is output from the respective connector that is patched to
MIX 1–48. At this time, you can choose to either fix the signal levels that are output from the input channels (FIX mode)
or allow them to vary (VARI mode). MIX buses that are set to FIX mode can be used as group buses, and MIX buses that
are set to VARI can be used as AUX buses.
In addition, the PM1D system has 24 independent MATRIX buses. Signals from MIX channels 1–48, STEREO A/B chan-
nels, and SUB IN can be mixed at the desired level and sent to a MATRIX bus. The signal sent to a MATRIX bus is routed
through a MATRIX channel that provides EQ, comp, and delay, and is output from the respective output connector that
is patched to MATRIX 1–24.

Scene memories/Libraries

The PM1D system can store the mix parameters of each channel and the settings of the entire PM1D system in memory
as a scene. Scenes are assigned a number consisting of an integer portion in the range of 00–99, and a decimal portion in
the range of .0–.9, for a total of 1,000 scenes from 00.0 to 99.9. (Ten of these scenes are read-only.)
Independently of scene memory, the PM1D system can store settings such as patch data, EQ data, compressor data, and
effect data in libraries for later reuse.

Word clock synchronization

In order for digital audio signals to be accurately transmitted and received, all components of the PM1D system and the
digital devices connected to the digital input/output units must be synchronized to the same word clock signal.
If any non-synchronized device is present, the input/output signals of that device may be muted, or may generate
click noise.

DSP
In Standard mode, the internal clock of the engine is normally used as the word clock master, and the input/output units
and console will be synchronized to this. It is also possible to use an external clock generator as the master that supplies a
word clock to the engine, console, and input/output units.

DSP
In Mirror mode, you can also switch to the other engine manually if the currently-used engine experiences difficulties. In
order to minimize the clock switching time in such cases, we recommend that you supply a word clock from an external
clock generator to the console and to engines A/B. Of course, switching will occur even without this type of supply
method.
Hint
For details on selecting the word clock master, refer to "CS1D Operation Manual (Start-up)" ( p.24) and to "CS1D
Reference Manual (Software)" ( p.44).
Hint
As an exception, the 2-TRACK IN DIGITAL jacks 1–6 of the CS1D console have built-in sample rate converters, and
will accept digital signals that are not synchronized with the PM1D system.
