4 stereo system input monitors
4ch external mix
DIM level control
Low noise, high-quality sound
19 inches 1U size

CSP331 is a monitor system of the stereo input of 4 systems.
It can use it for the insertion such as the talkback by a function to mix an external source of 4ch to the source which it chose.
It provides a super low noise and no coloring sound by parts selected carefully and superior circuit configuration.

“Source input”
It can choose one of the stereo sources of 4 systems.
It enables it to connect meters to the through output that a male and the female of the Dsub25 connector are connected to parallel.

“EXT input”
The external source of 4ch can set a mix level with front panel individually.
In addition, the external source chooses it in a GPI port.
When it does not use a GPI port, it can always turn it on with a switch of the rear panel.
In addition, as for the connector, maile and female of Dsub15 is linked to parallel.

“DIM”
It can use the DIM level of 0dB to -30dB continuous variables together with a monitor level to do a fine monitor level.

“Monitor level”
It can cut the L and R individually or together.
