• LINE 1: only LINE 1 input is sent to the mix bus to be amplified and delivered to the L
and R OUT outputs
• LINE 2: only LINE 2 is sent to the mix bus to be amplified and delivered to the L and R
OUT outputs
• MIC: only microphone (MIC) input is sent to the mix bus to be amplified and delivered
to the OUT L and R outputs
• LINE 1 + MIC: the LINE 1 and MIC inputs are mixed, amplified and delivered to the L
and R OUT outputs. If the TALKOVER function is active, the microphone signal
attenuates to that of the line when it exceeds the activation threshold
• LINE 2 + MIC: the LINE 2 and MIC inputs are mixed, amplified and delivered to the L
and R OUT outputs. If the TALKOVER function is active, the microphone signal
attenuates to that of the line when it exceeds the activation threshold
Select one of the 5 work modes in special selection mode with the rotating knob on the
front (see section 4.2. Special selection mode of active sources and adjusting settings for
details of the full procedure).
3.4. Audio output connections
The amplified output (OUT L and R) have Euroblock connectors.
The connection cable that connects the CA40 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, mono (same signal L+R and both channels) or
bridge (signal L+R amplified by both channels linked as one). These are selected using the micro
switches STEREO-BRIDGE-MONO on the rear panel (see section 7. DIAGRAM OF FUNCTIONS
for more information).
In bridge mode, the output signal connection is made through the positive terminals of
each of the L and R connectors, the positive terminal corresponding to the L channel of bridge.
Remember that the minimum work impedance for the amplifiers in mono or stereo mode
is 4, and when working in bridge mode it is 8. For correct operation of the CA40, under no
circumstances must you work with impedances lower than those specified above.
Attention: in bridge mode only the terminals indicated on the serigraph on the equipment
must be used for connecting the speakers.
Additionally, the CA40 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 y R.
3.5. 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
(LINE 1, LINE 2, MIC, LINE 1 + MIC, LINE 2 + MIC). The connection is made by a
standard CAT5 cable between the WPmVOL or WPmVOL-SR wall panel and the
REMOTE CA40 connector.
Because there is a CA40 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,
