6.3. Audio input connections
The CA40 accepts two types of signals in its input channels:
•
Microphone (
MIC
): has a balanced Euroblock or jack type connection, ready to
accept a signal level between -20dBV y
–
50dBV, with adjustable sensitivity with
the ADJ control
NOTE:
the microphone input has a phantom power supply to power condenser
microphones, activated by internal bridge (
•
Line signals (
LINE 1
,
LINE 2
): they have unbalanced minijack or double RCA type
stereo connections. They are prepared for input of between -6dBV and 0dBV, with
input sensitivity that can be adjusted by internal port (
). You can connect signals from CD players, radio
tuners, mixing consoles, media players, the audio outputs of PCs and tablets, etc.
to these connections.
NOTE:
Turntables CANNOT BE CONNECTED directly to this device because none of the
inputs have an RIAA preamp.
The CA40 has the following operating modes according to the input sources selected as
active:
•
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
