INSTALLATION AND CONNECTIONS
4.4 Control Inputs
4.4.1 CONTROL INPUTS
The CONTROL INPUTS (16) are eight freely configurable control inputs, which are provided via Phoenix-type terminals on the rear of the appliance. Closing (connection to ground) a control contact switches to the corresponding configuration (preset). Simultaneously closing several contacts selects the preset with the highest priority setting. When all control inputs are open (idling mode), the DRM 4000 is set to its BASIC CONFIGURATION.
As shipped, the configurations of the eight control inputs have been factory-pre-programmed for using the DRM 4000 in a multitude of applications. For further detail, please refer to chapter 8 and to the additional information sheet “DRM 4000 FACTORY CONFIGURATION”.
Employing the optionally available interface boards (NRS 90256 for RS-485 or NRS 90258 for RS-232) together with the “DRM 4000 Editor” software lets you freely configure and store the 8 control inputs according to your personal requirements; accessible parameters are: routing, ducking control, muting and VCA. Additionally, assigning individual priorities to each contact is possible. This allows you to establish security-relevant settings using the “Priority Override” function; e.g. routing for alert announcements. For an exact description of all possibilities and programming examples, please refer to chapter 7.4 “Software Description”.
4.4.2 External VCA-Control
The two VCA-control inputs (17) that are carried out as Phoenix-type terminals on the rear panel of the appliance allow accomplishing voltage-controlled volume setting of the two output channels, which provides the possibility to individually and remotely set the volume levels for different rooms or areas. Volume setting is accomplished either via externally connected potentiometers or switchable resistors or via an externally generated DC-voltage (0V - 10V), where at 0V the output signal is not attenuated and at 10V the output audio signal is attenuated by 90 dB. The following example shows the wiring for remotely controlling the volume via external potentiometer as well as a second example, which shows how to remotely control the volume setting via control voltage that is generated in an external unit (DCS 416).
