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.

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 for 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 connecting 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 types such as XLR plugs and TSR jacks. Breakout boxes should be connected to
the BCS70 using shielded Sub-D cable.
Installation into the cabinet
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 f ind a set of DIP-s w itches 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 equipment-
specific 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 function 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 suffice for most equipment. In
order to be able to connect up equipment w ith non-standard operation or tally outputs, it is
possible that other control softw are w ill be required, for example, or that any tally outputs w ill
have to be combined. In case of doubt or for special requirements, please contact Dateq.
BCS73 DIP-sw itch settings
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 from 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 type 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 on-
air situation. You can use DIP-sw itch 4 to select talk-back w hen on-air. If you use passive
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).

The BCS78 master (monitor) module has a number of connectors for audio inputs and outputs
and on-air indicating on the connector board.
AIR / SPARES 15-pin female Sub-D connector to w hich the balanced audio signals
for AIR, SPARE 1 and SPARE 2 can be connected. These inputs are
not electrically isolated. If a tuner w hich is connected to a cable
netw ork is connected up this can lead to an earth loop. To prevent this
it is advisable to have an isolating transformer in the aerial or audio
cable(s). These inputs can, for example, also be used for post-tape
check w ith recordings.
ANN / GST 1 / GST 2 15-pin female Sub-D connector w ith three independent stereo outputs
to w hich headphones of Announcer, Guest 1 and Guest 2 can be
connected directly. Also unbalance stereo Studio output.
INSERTS Balanced insertion points in the stereo PGM signal.
CR-L / CR-R Electronically balanced male XLR-3 outputs. These are used for
connecting the amplifier to the speakers in the Control Room. The
Control Room selector sw itches are used to select w hich signal can
be heard via this output. The volume of this output is determined w ith
the C.R. volume control. The Control Room output is automatically
sw itched off to prevent acoustic feedback.
AIR- L / AIR- R T RIM The level of the AIR input can be trimmed. Use a small screw driver to
adjust the trimmers.

BCS70 Connector board
At the back of the script space there are, in addition to the audio outputs of the BCS70,
various other connectors. There is also space f or expansions such as extra audio outputs or
special accessories.
PGM-L/R/M ProGraM outputs (Left, Right and Mono). The PGM output is the mixer
unit's main output. These balanced outputs are electrically isolated
using transformers and are therefore suitable for carrying signals to
cable modulators, transmitters and music lines, for example.
AUD- L /R/M AUDition outputs (Left, Right and Mono). All channels for w hich the
AUD sw itch is pushed in can be heard on the AUD output. The AUD
output can, f or example, be used as decor output, as post-fader
effect send, as extra output f or a second edition of a programme, or to
quickly record a telephone interview w hilst the broadcast carries on
normally over the PGM output. The AUD control on the master module
controls the total A UD level.
AUX-L/R/M AUXiliary outputs (Lef t, Right and Mono). These outputs can be used
to connect special-effects equipment, for example. Whether a channel
can be heard on the output is dependent on the setting of the AUX-
routing sw itches. In addition, the PRE / POST jumpers can be used to
select w hether a channel must be mixed independent of or dependent
on the fader status on the AUX output. The AUX control on the master
module controls the total AUX level. Return signals from effects
equipment can be sent to the PGM output via a normal input module.
CL OCK ANT ENNA If a Dateq BCS81 clock / timer is used, the external DCF-77 aerial can
be connected here.
TOP CONSOLE 25-pin female Sub-D connector for the meter bridge.
MCA-100 Connector for Dateq MCA-100 headphone amplifiers so that more
