6.3. Audio input connections
The CA120 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 (
LINE1, LINE2, LINE3
): 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 CA120 has the following operating modes according to the input sources selected
as active:
•
LINE1
: only LINE1 input is sent to the mix bus to be amplified and delivered to the
L and R OUT outputs
•
LINE2
: only LINE2 is sent to the mix bus to be amplified and delivered to the L and
R OUT outputs
•
LINE3/MIC
: only microphone (MIC) / line (LINE3) input is sent to the mix bus to be
amplified and delivered to the OUT L and R outputs
•
LINE1 + LINE3/MIC
: the LINE1 and LINE3/MIC inputs are mixed, amplified and
delivered to the L and R OUT outputs. If the TALKOVER function is active, the
LINE3/MIC signal attenuates to that of the LINE1 when it exceeds the activation
threshold
•
LINE2 + LINE3/MIC
: the LINE2 and LINE3/MIC inputs are mixed, amplified and
delivered to the L and R OUT outputs. If the TALKOVER function is active, the
LINE3/MIC signal attenuates to that of the LINE2 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 7.2. Special active source selection mode and setting adjustments
for
details of the full procedure).
