EN Dateq BCS70 Manual Introduction 3
Introduction
The Dateq BCS70 is a modular mixer unit which has been designed specially for use in radio
studios. The mixer unit consists of a frame (a split version is also available) with external power
supply, combined master / monitor module and various input modules.
Frame
The frame can take a maximum of 18 input modules, a script space and a master module. The
input modules can be positioned where wished in the frame. The BCS78 master / monitor
module is positioned at the right of the frame and the script space is positioned preferably in the
middle. A meter bridge is positioned on top of the frame. This contains a BCS62 VU, a 50
segment LED-bar meter with peak hold or a 101 segment Neon-bar meter. The meter bridge can
be expanded to include a BCS81 DCF-77 controlled clock / timer and a BCS68-2 extra set of 4
LED bar meters of 40 segments for reading CUE and AUD levels for example.
Pow er Supply
The BCS70 has an external power supply to prevent magnetic interference from the transformer.
The power supply is 19" wide, 2HE high and is connected to the frame via a 7-pin XLR
connector.
Input modules
There are many different modules available. All the modules (mono, stereo and telephone) are
available with and without tone control. The mono and stereo modules have two inputs which
are identical as regards facilities and which are available both with and without gain control.
The telephone module does not have a gain control because it is assumed that the external,
preferably digital, hybrid has an auto-gain function. Every module is equipped with trimmers to
allow the volume of all audio inputs and outputs to be set precisely. These controls are sited on
the modules' connector boards. The use of jumpers for modules is now minimal, most user
functions can be set via the software using a simple Setup function.
Microcontrollers
Each module is controlled by its own microcontroller. This controls all audio connections and
connected equipment. The microcontrollers can communicate with each other to allow 'global'
functions such as the control room mute and the Setup mode. Because all 'intelligent' functions
are contained within the software of the microcontroller, user-specific operation can easily be set
up without hardware modifications. What the user must specify is the type of equipment
connected to an input. There are a maximum of 16 preferred settings from which to choose.
Controls such as pulse/continuous contact, internal or external tally can be changed by this
means. Some 'non-standard' controls are pre-programmed, such as the standard setting for
Nautilus JukeBox automation, 360 Systems DigiCart and Denon CD and MD players.
