DESCRIPTION
CR-44 is equipped with two pairs of outputs on balanced XLR connectors (monitor A, monitor B), one pair of inputs on balanced XLR connectors (Input A), and on balanced TRS connectors (Input B) or, as an alternative, on 3.5 mm stereo mini-jacks. The passive volume control ensures a transparent dimming of audio signal. The rich set of controls allows input and output selection, muting, 20 dB dimming, and, last but not least, the Side Listen function, which allows the selective listening of stereo mix in its more “side” space zones.
CONTROL PANEL
-
INPUT A/B
Lever that allows selection of input A or input B. -
DIM
Button that enables dimming (-20 dB), useful for example to allow temporary conversation in the control room. -
MUTE
Button that allows temporary muting of the audio signal. -
VOLUME
Allows to adjust the listening volume (range: -∞, MAX). -
MONITOR A/B
Lever that allows selection of listening monitor pair A or B. -
SIDE LISTEN
Button that allows to reverse the L left channel phase (the R channel phase is unchanged). In stereo mix listening, when this button has been pressed, the center (mono) zone is excluded in favour of the “side” zone. If the MONO button is pressed when this function is enabled, the listening output is almost null. -
MONO
Button that allows to play the same left and right audio signal on each of the channels (L, R). -
XLR CONNECTORS, MONITOR A (L, R)
Balanced XLR outputs, for connection of a first stereo pair of Monitors. -
XLR CONNECTORS, MONITOR B (L, R)
Balanced XLR outputs, for connection of a second stereo pair of Monitors. -
INPUT A, XLR CONNECTORS (L, R)
Balanced XLR inputs for connection of a stereo source A. -
INPUT B, TRS CONNECTORS (L, R)
Balanced TRS inputs for connection of a stereo source B. -
INPUT B, STEREO CONNECTOR
Stereo input (parallel to input no. 11) on 3.5 mm mini-jack.
