3. INSTALLATION

Non-compliance with the instructions or neglecting warnings may cause malfunction or even
damage the unit:
1. Avoid turning on the device without the speakers connected to its outputs and
without having previously set the volume/gain controls to minimum level.
2. Always use shielded cables to make connections between devices.
3. In an amplifier, avoid placing the speaker output cables close to other signal cables
(micro, line...). This may cause the system to oscillate, damaging the amplifier and speakers.

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:
