6.4. Audio output connections
The amplified output (
OUT L
and
R
) have Euroblock connectors.
The connection cable that connects the CA120 connectors and the speakers should be
good quality, with a suitable cross section and as short as possible.
The outputs can operate in stereo mode or mono (same signal L+R and both channels).
These are selected using the micro switches
STEREO-MONO
on the rear panel (
section 9 DIAGRAM and LIST OF FUCNTIONS
Remember that the minimum work impedance for the amplifiers in mono or stereo mode
is 4
. For correct operation of the CA120, under no circumstances must you work with
impedance lower than specified above.
Additionally, the CA120 has an unamplified auxiliary output (
AUX OUT
) which makes it
possible to connect it to amplifiers or with other external devices. The auxiliary output
AUX OUT
has a line level signal (0dBV) which is an unamplified replica of the signal
delivered to the terminals
OUTPUT L

6.5. Remote control options
•
REMOTE
port: the RJ-45
REMOTE
type connector allows the connection of a
WPmVOL or WPmVOL-SR (control 0-10 VDC) wall control panel to adjust the
general output volume and/or to select one of the five active work source modes
(LINE1, LINE2, LINE3/MIC, LINE1 + LINE3/MIC, LINE2 + LINE3/MIC). The
connection is made by a standard CAT5 cable between the WPmVOL or
WPmVOL-SR wall panel and the REMOTE CA120 connector.
Because there is a CA120 WPm type control as well as other types of control (front
knob, infrared control and serial port control) the most recent adjustments by any
of these methods will prevail. For example, if an active source is selected and/or a
volume adjustment is made using the WPmVOL-Sr wall panel connected to the
REMOTE
port, and then these settings are adjusted using the front control, the
adjustment made with the frontal control will prevail. In this case, when the wall
panel position is adjusted again, the CA120 will change to the values indicated,
and so on and so forth.
•
MUTE
port: The
MUTE
connector makes it possible to connect a power free contact
to totally silence the CA120 if an external device works on it (example: a
emergencies and centralised evacuation warning system).
