3. INSTALLATION

3.1. Location and assembly

The CA120HZ 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 = 30Ω, or lower).
The environment 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 CA120HZ 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 (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 (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 CA120HZ has the following operating modes according to the input sources selected as
active:
• LINE1: only the LINE1 input is sent to the mix bus to be amplified and routed to the OUTPUT in
mono format
• LINE2: only the LINE2 input is sent to the mix bus to be amplified and routed to the OUTPUT in
mono format
• LINE3/MIC: only the microphone (MIC) / line (LINE3) input is sent to the mix bus to be amplified
and routed to the OUTPUT in mono format
• LINE1 + LINE3/MIC: the LINE1 and LINE3/MIC inputs are mixed, amplified and routed to the
OUTPUT in mono format. If the TALKOVER function is enabled, the LINE3/MIC input will
attenuate the LINE1 signal when the activation threshold is reached
• LINE2 + LINE3/MIC: the LINE2 and LINE3/MIC inputs are mixed, amplified and routed to the
OUTPUT in mono format. If the TALKOVER function is enabled, the LINE3/MIC input will
attenuate the LINE2 signal when the activation threshold is reached
