3.4. Audio output connections
The amplified outputs (OUT L (A) and R (B)) are equipped with Euroblock connectors.
The cable that connects the CA200z outputs and the speakers should be of good quality,
with a suitable cross-section and as short as possible.
The outputs can operate in stereo mode, mono mode (same L+R signal in both channels),
bridge mode (L+R signal amplified through both channels, linked together as one) or ZONES A and
B independently (each output receives a set combination of active audio sources and volumes).
Modes are selected from the unit's SETUP menu (see section 4.2 Special setup mode for more
information) or from an external device using the serial or RS-232 port.
In bridge mode, the output signal is connected through the terminals marked BRIDGE +
and - on the rear panel.
Remember that the minimum operating impedance for the amplifiers in mono or stereo
mode is 4 , and 8 when working in bridge mode. For the correct operation of the CA200z, under
no circumstances should you work with impedances lower than those specified above.
Attention: only the terminals indicated as BRIDGE on the unit's serigraph can be used for
connecting the speakers in bridge mode.
Additionally, the CA200z has an unamplified auxiliary output (AUX OUT) which makes it
possible to connect it to amplifiers or other external devices. The auxiliary output AUX OUT supplies
a line signal level (0 dBV) which is an unamplified replica of the signal delivered to the terminals
OUTPUT L and R.
3.5. Remote control options
 REMOTE1 and REMOTE2 ports: each RJ-45-type REMOTE connector can be
connected to a WPmVOL or WPmVOL-SR wall control panel (control 0-10 VDC).
In STEREO, MONO and BRIDGE modes, the panel connected to the REMOTE1
port actuates on the 2 amplifier outputs and the REMOTE2 port is disabled. In
ZONES A and B mode, the panel connected to the REMOTE1 port is associated
to output A, and the panel connected to the REMOTE2 port to output B.
The following can be controlled from each panel (*):
o the general volume adjustment of the associated output (A, B, or both),
depending on the operating mode selected,
STEREO/MONO/BRIDGE/ZONES
o the selection of the LINE source for the associated output (OFF, LINE1,
LINE2, LINE3, LINE4)
o the selection of a preset, from 1 to 5 (**), which, when selected,
recovers the configuration that was stored in memory when the preset
was saved (source selection, updating adjustments, volumes, etc.)
(*) WPmVOL can only control the volume, whereas WPmVOL-SR can control
the volume and select sources or presets
(**) In ZONES (A and B) mode, only one of the two remote panels can
recover presets (when this function is activated in one panel, the option
automatically disappears from the SETUP menu of the other)
The connection is made with a standard CAT5 cable between the WPmVOL
or WPmVOL-SR wall panel and the CA200z's REMOTE connector.
