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 CA200z can be installed on a tabletop, in a standard 19" wide rack cabinet or in a
standard 9.5" wide half-rack cabinet. Any of these installation options is possible using the available
rack installation accessories (kit of 2 2UHRMKIT supports, not included as standard).

3.2. Mains connection

The amplifier is powered by alternating current through its internal power source: 90-
264VAC and 47-440Hz.
The amplifier's AC power cable must be earthed through its mains cable (earth resistance
Rg = 30 or lower). The working environment should be dry and completely dust-free. Do not
expose the unit to rain or water splashes. Do not place liquid containers or incandescent objects
such as candles on top of the unit.
Always
connecting/disconnecting the amplifier. 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 audio
cables that transport the signal.

3.3. Audio input connections

The CA200z accepts two types of signals in its input channels:
•
Microphone (MIC): with balanced Euroblock-type connections on the rear panel or
jack (MIC2) connections on the front panel that can accept a signal level between
-20 dBV and –50 dBV with adjustable sensitivity through its ADJ control
Note: The microphone inputs have phantom power to supply condenser microphones, activated
by the internal jumper (see 10. CONFIGURATION DIAGRAM section). This option comes
disabled (OFF) by default or from the factory.
•
Line signals (LINE 1 to LINE 4): equipped with a non-balanced mini jack stereo
connection on the front panel (LINE 2) or double RCA on the rear panel (LINE1 to
LINE4). They can admit nominal signals of -6 dBV and 0 dBV, with input sensitivity
that can be adjusted through internal jumper (see section 10. CONFIGURATION
DIAGRAM). These can be used to connect signals from CD players, radio tuners,
mixing consoles, media players, PC and tablet audio outputs, etc.
Note: Turntables CAN NOT BE CONNECTED directly to this device because none of the inputs
have an RIAA preamp.
