3. INSTALLATION
3.1. Location and assembly
The CA40 is suitable for installation on a wall or under a surface (table, shelf, cupboard,
etc.), thanks to its design and layout of its connectors, controls and LED indicator lights.
3.2. Mains connection
The amplifier is powered by alternating current through its external power source: 100-240
VAC and 50-60 Hz.
This apparatus must be earthed through its mains cable (earth resistance, Rg = 30
, or
lower). The atmosphere should be as dry and dust free as possible. Do not expose the unit to rain
or water splashes. Do not place liquid containers or incandescent objects like candles on top of
the unit.
Should any work or connection / disconnection task be done, always disconnect the unit
from the mains supply. There are no elements that can be manipulated by the user
inside the amplifier.
To avoid buzzing, do not allow the power cable to intertwine with the shielded cables
that transport the audio signal.
3.3. 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 (see section 10.
CONFIGURATION DIAGRAM).
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 (see section 10.
CONFIGURATION DIAGRAM). 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
