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 module s

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.

EN Dateq BCS70 Manual Installation 4

Installing the mixer unit

The BCS70 is supplied as standard w ithout a cabinet or connector cables. It is possible to
make cables f or connection to the Sub-D connectors of the various input and output modules
in-house. In that case, metal caps for the Sub-D connectors and cables w ith a separate
screening should be used, as per the CE norms.

Breakout boxes

Another possibility f or c onnecting the mixer unit is to make use of so-called 'breakout boxes'.
All non-standard Sub-D connector on the rear of the BCS70 can be split up into more usual
connector ty pes such as XLR plugs and TSR jacks. Breakout boxes should be connected to
the BCS70 using shielded Sub-D cable.

Installation into the cabine t

The BCS70 frame fits into an opening of 1050 x 547 x 75 mm (W x H x D). Without the meter
bridge the mixer unit projects 72 mm above the table top, w ith the meter bridge the highest
point is 205 mm. See also the dimensioned draw ing below .

EN Dateq BCS70 Manual Installation 5

Setting the type of equipment connected

Each module has a quad DIP sw itch for selecting the type of control of equipment connected
to an input. Therefore, on the BCS71 and BCS72 you w ill find tw o sets of DIP-sw itches (one
for each input). On the BCS73 you w ill find a set of DIP-s w itc hes f or other f unctions.

BCS71 and BCS72 DIP-sw itch settings

For each input you can select from 16 types of operation for the equipment connected.
Whereas previously the only choice w as pulse or continuous contacts, now equipment­specific operation can also be selected. This concerns equipment w hich, in addition to
standard operation, also has special functions or has to be operated in a non-standard w ay.

As standard, a choice can be made betw een continuous or pulse contacts (short or long
pulses), indication of internal or external tally on the ON and OFF buttons, giving a start pulse
again by pressing the ON button (Restart) and activating the CUE f unction by putting the
equipment w ith sw itched off module into the 'PLAY' state (Remote Cue).

Use of non-standard equipment

One of the patterns given in the table on the previous page w ill suf f ice for mos t equipment. In
order to be able to connect up equipment w ith non-standard operation or tally outputs, it is
pos sible that other c ontrol sof tw are w ill be required, for example, or that any tally outputs w ill
have to be c ombined. In case of doubt or for special requirements, please c ontact Dateq.

BCS73 DIP-sw itch se ttings

The BCS73 w as originally designed for use w ith an external Telos ONE digital hybrid.
Therefore, connecting the ‘remote control’ cable is very easy. By default, the Telos ONE is
controlled by pulses. If you w ant to use a hybrid that must be controlled in a non-Telos w ay,
you can use DIP-sw itch settings corresponding to a control-pattern f rom the table below :

Control patterns available:

DIP-switch 1 DIP-switch 2 DIP-switch 3 Description Hybrid On / Off

Off Off Off Telos ONE (default) Pulse 100ms
Off ON Off Long pulses Pulse 500ms
ON - (don’t care) Off Continuous Continuous
Off Off ON DATEQ TH-2 Inverted pulse 100ms
Off ON ON Inverted long Inverted long pulse 500ms
ON - (don’t care) ON Continuous inverted Continuous inverted

The Telos ONE is a digital hybrid. If you use this ty pe of hybrid, the rejection of return audio in
your program material is so high that you may w ant to allow talk-back to a caller during an on­air situation. You can use DIP-sw itch 4 to select talk-back w hen on-air. If you use pas sive
hybrids or active hybrids w ith a low er rejection ratio, it is advisable to disable the talk-back
option. Otherw ise it is possible to hear the talk-back audio in your program w ith possible nasty
consequences...

Talkback if hybrid is on-air:

DIP-switch 4 Description

Off No talk-back if the hybrid’s audio is used in your program
ON Talk-back allowed, even if the hybrid’s audio is used in your program

Phantom power supply

Non-dynamic microphones usually need a 48V external pow er supply. If this pow er has to be
supplied by the BCS70, place jumper P7 in the ‘ON’ position. +48VDC (related to the (0)-input)
will be supplied to both the (+) and the (-) input.

Jumper P7 is positioned next to the bus connector of the BCS71(GE) module. The factory
default for this jumper is ‘OFF’.

Warning: central muting of multiple microphone channels

To prevent the line1/line2-selection of the input-modules from malfunctioning, pins #14
(common Cue / Cough) of the input-connectors can not be connected to each other. When
using a system that mutes multiple microphone channels with the ‘cough’-input (like FlexCom
FXS-D extensions), please note that if this system uses a common ground (like the FXS-D),
don’t connect this ground to pin #14 (common Cue / Cough), but rather use #13 (Frame) or
#25 (Ground).
