Audio Output Connections; Remote Control Options - Ecler CA120HZ Bedienungsanleitung

Select one of the 5 work modes in special selection mode with the rotating knob on the front (see
section 4.2. Special selection mode of active sources and adjusting settings for details of the full
procedure).

3.4. Audio output connections

The amplified OUTPUT uses a Euroblock connector.
The connection cable between the CA120HZ output and the speakers should be of good quality,
with a suitable cross section and as short as possible.
The output operates in mono mode only (L+R summed in case of active stereo input).
Additionally, the CA120HZ has an unamplified auxiliary output (AUX OUT) which makes it possible
to connect it to amplifiers or with other external devices. The auxiliary output AUX OUT has a line level
signal (0dBV) which is an unamplified replica of the signal delivered to the OUTPUT terminals.

3.5. Remote control options

•
REMOTE port: the RJ-45 REMOTE type connector allows the connection of a WPmVOL or
WPmVOL-SR (control 0-10 VDC) wall control panel to adjust the general output volume
and/or to select one of the five active work source modes (LINE1, LINE2, LINE3/MIC, LINE1
+ LINE3/MIC, LINE2 + LINE3/MIC). The connection is made by a standard CAT5 cable
between the WPmVOL or WPmVOL-SR wall panel and the REMOTE CA120HZ connector.
Because there is a CA120HZ WPm type control as well as other types of controls (front
knob, infrared control and serial port control) the most recent adjustments by any of these
methods will prevail. For example, if an active source is selected and/or a volume adjustment
is made using the WPmVOL-Sr wall panel connected to the REMOTE port, and then these
settings are adjusted using the front control, the adjustment made with the frontal control will
prevail. In this case, when the wall panel position is adjusted again, the CA120HZ will change
to the values indicated, and so on and so forth.
•
MUTE port: The MUTE connector makes it possible to connect a power free contact to totally
silence the CA120HZ if an external device works on it (example: a emergencies and
centralised evacuation warning system).
•
RS-232 port: the serial communication port RS-232 allows remote management of the
CA120HZ from a computer
external control system supporting this protocol. See the CA-NET protocol manual for
detailed information on the connection and syntax of the commands supported. The
connection has the following specifications:
o Baud rate: 9600 (fixed, without auto negotiation)
o Data bits: 8
o Parity: None
o Stop bits: 1
o Flow control: None
•
Receiver IR: the built-in IR receiver gives general volume control of the CA120HZ and its
MUTE ON / OFF function from the REVO-IR remote control included with the unit.
