Introduction

The DATEQ BCS50 mixer-series is especially developed to be used in a broadcast­environment. The large number of built-in automations makes this mixer ideally suited in any
self-supporting studio.

Frame

The BCS50 mixer is a modular system existing of a frame, a master module and free to
choose input-modules. The frame can contain up to 16 input modules and a master module.
The power-supply is built into the frame.

Input modules

A large number of input modules is available:

BCS53 Telephone module with built-in analogue telephone

hybrid

1x XLR
1x XLR-M

BCS53T Telephone module to connect an external (digital)

telephone hybrid

SUB-D-15

The position and the number of modules is variable. The only limitation is the number of
analogue telephone hybrids that can be used simultaneously (maximum 2 or 3, depending on
the quality of the subscriber line).

When digital telephone hybrids are used more than 2 lines can be on the air simultaneously.
This is because digital hybrids have a better trans-hybrid attenuation.

Mastermodule

The BCS50 mastermodule has all the mix,- and output amplifiers and various volume­controls. This module is placed at the most right position in the frame.

Meterbridges

The BCS50 meterbridge can house the following readouts:

• BCS121: DCF77 atomic-clock/ timer/ stopwatch

• Analogue moving-coil meter, or 2x 50 segment digital horizontal LED VU meter with peak

indicator

• BCS68: dual 2x 30 segment digital vertical LED VU meter with peak indicator

4 Introduction DATEQ BCS50 user manual EN

Outputs

PGM (program) output

The PGM-output is the main-output of the mixer. All channels with the PGM-switch
pushed feed their signal to the PGM-buss. The PGM-signal is available on three XLR­connectors: mono, left and right. All these outputs are electronically balanced. Besides
these outputs the BCS50 has three unbalanced PGM-outputs on 6.3mm stereo jacks
(PGM1/PGM2/PGM3). These connectors can be used link to other equipment located
inside the studio, like amplifiers etc.

AUD (audition) output

All modules with the AUD-switch pressed will be audible on the AUD-output. The AUD­output can for example be used to connect to various recorders. The AUD-volume
control on the master will adjust the overall audition-volume. The unbalanced AUD-output
is available on a 6.3mm stereo jack.

AUX (auxiliary) output

The auxiliary output can be used for a director-link. All channels can feed their signal to
the AUX-buss. With an internal PRE/POST-jumper the signals source can be switched
to pre-fader (independent of the fader) or post-fader (signals volume is dependent of the
fader). The master-modules AUX-volume controls the overall AUX-level. The unbalanced
AUX-output is available on a 6.3mm stereo jack.

The AUX-buss may also be used to connect effect-equipment. The effect-return signal
can be inserted at any normal input-module. You will have to turn off the AUX-switch at
this channel to prevent a feed-back!

CR (control room) output

At this output the amplifier for the technical-room can be connected. The selection
switches on the master determine the signal-source that will be heard on this output. All
sources can be monitored.

This output can be muted automatically when a microphone in the technical-room is
active to prevent an acoustical feedback.

STUDIO output

Connect the amplifier for the presentation-room here. This output can have the same
signal as the CR output. It is also possible to switch to the AIR or the PGM signal.

ON-AIR 1 and 2 outputs

External ON-AIR indicators (like the DATEQ OA-1) can be connected to the ON-AIR­outputs. These two outputs are freely programmable with jumpers on the input modules.
When ON-AIR1 is activated the studio output is muted. When all the microphones in the
studio are switched to ON-AIR1 an acoustical feedback will be prevented!

ANNOUNCER

The announcers headphones can be connected here. When the technician pushes the
TALK-button he will be audible on this output, otherwise the program signal or the CR
signal (depending on the CR-switch on the master) can be heard.

EN DATEQ BCS50 user manual Introduction 5

GUEST

The guests headphones can be connected here. This output contains the PGM-signal,
except when the PGM/TALKBACK switch on the master is pressed; then the output has
the same signal as the ANNOUNCER-output. The guests will also hear the technician
when he presses the TALK-button.

By switching the PGM/TALKBACK to PGM the guests will not become confused when
the technician uses the TALK button.

Inputs

AIR/ SPARE1/ SPARE2 inputs

The AIR signal is to be used to connect the program-signal after it has gone all the way
from the studio to the listener, for example with a tuner. At the SPARE inputs the
processed studio signal can be returned, or the signal of a secondary studio can be
connected. Keep in mind that these inputs are not electronically isolated.

When using a tuner connected to a cable-network earth-loops are created. To prevent
earth-loops an isolation-transformer can be used in the audio-wires, or at the RF­connector.

TALKBACK IN

The external talkback-input can be used to connect a (to line-level amplified) director­microphone. When the contact is made this microphone is routed to the PFL-buss, and
the CR signal will automatically switch to PFL, so that everyone listening to the CR will
hear the director. When the announcer must hear the director, the CR-switch on the
master has to be pressed.

POWER

Mains input (115 or 230 VAC; internally selectable, 100 Watts).

DCF-ANT

Input for the active aerial supplied with the BCS121 clock-timer.

BCS53 Telephone modules

An analogue subscriber line can be directly connected to a BCS53 module. This module has
a built-in analogue hybrid. When more than two BCS53 modules are on air simultaneously
the program-signal will get coloured. It is possible to have more than two lines off-hook when
they are not on-air. When more than two phone-lines must be on-air simultaneously the
BCS53T modules in combination with a digital hybrid should be used.

GAIN Input-sensitivity control. When the gain is turned CW the

incoming signal will be amplified and the return signal will be
attenuated.

RINGER The LED flashes on an incoming call.

ADJUST R-balance adjust for tuning the internal hybrid for minimal return

signal. This control has to be adjusted so that a minimum of sound
coloration will occur during the telephone conversation.

TEL. ON By pressing the button the phone-line will go on,- or off-hook.

AUX Routes the signal to the AUX-buss.
AUD Routes the signal to the AUD-buss.
PGM Routes the signal to the PGM-buss.

PAN Panorama control. Places the mono-sound in the stereo image.
OVERL. This LED illuminates when the signal in the module is too high,

and in danger of becoming distorted.

PFL Pre-Fader Listening. By pressing this switch the signal will be

audible on the head-phones. The hybrid will automatically go off­hook.

ON Switch to activate the module. When the ON-lamp lights up the

signal can be heard on the selected busses (AUX, AUD, PGM).
When faderstart is configured the lamp will automatically light up
when the fader is opened.
When the module is activated the PFL function will reset.

FADER With the fader the signal-level can be controlled. The nominal level

is 0dB.

To a BCS53T module an external digital (Telos) hybrid can be connected. A digital hybrid has
a superior trans-hybrid loss than an analogue hybrid. The advantages are a better sound­quality and the fact that more than two lines can be active at the same time. The exact
amount of possible active lines depend on the quality of the subscriber lines and the trans­hybrid loss per module.

GAIN Input sensitivity control. When the gain is turned clockwise the

incoming signal will be amplified and the return signal will be
attenuated.

TEL. On and off switches to remote control the Telos hybrid.
ON/ OFF The lamps alternately blink on an incoming call.

AUX Routes the signal to the AUX-buss.
AUD Routes the signal to the AUD-buss.
PGM Routes the signal to the PGM-buss.

PAN Panorama control. Places the mono-sound in the stereo image.
OVERL. This LED illuminates when the signal in the module is too high,

and in danger of becoming distorted.

PFL Pre-Fader Listening. By pressing this switch the signal will be

audible on the head-phones. The hybrid will automatically go off­hook.

Jumper settings

The jumpers in a BCS53 and BCS53T module have the same functionality and the same
position. That is why only the BCS53 PCB is shown below.

Jumper name Possibilities Description

CUE (1) FADER (D) The channel is activated when the fader is opened.

SWITCH The channel is activated when the ON-key is pressed. When the fader

is opened and the ON-lamp does not light up no audio will be fed
through.

AUX (2) POST (D) The after-fader signal is routed to the AUX-buss. Both jumpers (P6

and P7) have to be in the same position!

PRE The pre-fader signal is routed to the AUX-buss. Both jumpers (P6 and

P7) have to be in the same position!

ON-AIR (3) OFF (D) No ON-AIR outputs will be activated when the channel is switched on.

ON-AIR1 When the channel is switched on ON-AIR1 will be activated. The

studio output will be muted to prevent an acoustical feedback.

ON-AIR2 When the channel is switched on ON-AIR2 will be activated.

MSTR (4) ON (D) When the PFL-switch is pressed the CR will switch automatically to

PFL. This makes the signal directly audible for the technician.

OFF The signal is mixed to the PFL-buss, but the CR-selector will not

automatically switch to PFL.

DJ (5) ON When the module is activated all PFL-buttons will reset and the CR

output will be muted to prevent from an acoustical feedback with the
DJ-microphone. It is also possible to let the CR-selector switch to AIR
or PGM. This will be explained later.

OFF (D) This function is disabled.

Operation of the BCS50 master
AUX This control adjusts the volume of the signal on the AUX-output.
METER The VU-meter has the possibility to monitor the PGM signal, but it is also possible to

monitor the C.R. signal. All available signals in the BCS50 can be monitored. This
makes it possible to monitor the PFL signal of a channel so that the gain-setting can
be tuned (0dB is the nominal level).

AUD This control adjusts the volume of the signal on the AUD-output.
C.R. The C.R. selector selects the source that can be heard on the C.R. speakers and

SEL. the technicians headphones. Due to the built-in automations another LED than the

LED underneath the selected key can illuminate. The monitored source is the source
indicated by the LED.

C.R. Volumecontrol for the C.R. speakers. When the DJ-microphone is active
MUTE the C.R. will be muted. The mute LED illuminates.

T.B. MIC With the built-in microphone the technician can talk to the announcer and the
TALK studio output. The microphone is activated by pressing the talk-button. It is also

possible to talk to the guest. To do so the PGM/TB switch has to be pressed.

GUEST Volumecontrol for the guest headphones.
PGM/TB When this switch is pressed the guest headphones will be linked to the same source

as the announcer headphones. When the switch is not pressed the program signal will
be heard.

ANN. Volumecontrol for the announcer headphones.
STUDIO Volumecontrol for the studio speakers.
PGM/AIR These two keys determine the source for the studio and the announcer outputs.

C.R. When the C.R. key is pressed these two outputs will be linked to the C.R. source.

When the key is not pressed the outputs will be linked to PGM or to AIR.
By activating this function the announcer can talk to a guest on the telephone while

he is off-air. To do this the announcers microphone and the telephone module must
be switched to PFL. The technician can also talk to the guest by switching his own
microphone to PFL.

PGM/AIR When the DJ-microphone is active the BCS50 master can automatically switch to the
+PFL AIR or PGM signal. With the PGM/AIR switch you can select between these two

sources. When the mixer is used as a recording unit over the AUD-buss while the
normal radio-signal is fed through the PGM-buss this function is unpractical. That is
why this function can be disabled. The +PFL key makes it possible to monitor the
program or the air signal (depending on the PGM/AIR switch) when listening to PFL,
so that the technician can monitor the current program. The signal is added at a

-20dB level.

Jumper settings

With two jumpers the AutoPFL function can be configured. The jumpers are situated on a small
add-on PCB at the left PCB of the BCS50 master unit.
By default the mixer is configured to disable the AutoPFL function when the C.R. selector is
switched to audition. In all the other cases the C.R. selector will automatically switch to PGM or
AIR when the DJ-microphone is activated. It is also possible to disable this function when AUX is
selected or to disable all AutoPFL functionality. See the table below:

BCS121 clock/timer module

The BCS121 clock/timer-module receives its time-of-day­information from the German DCF77-transmitter at
Mainflingen (near Frankfurt). The range of this transmitter is
approximately 1000 miles. Besides extreme accuracy, the
BCS121 keeps track of daylight-saving-time etc. Unique is
the infra-red remote control for selecting operation mode
and entering time.

Timer

The timer can be used counting up or down. The [MODE]-key selects the desired mode:

TIMER COUNTING UP

In the initial mode the BCS121 counts upwards from 0:00.0. This mode can be useful for
keeping track of the elapsed time since the last record, jingle or other item was started.
Triggering the timer with a microphone-channel can be useful to monitor the length of the
‘spoken’ parts of a radio-program.

TIMER COUTING DOWN

To indicate the (approaching) end of a pre-recorded item, for example, the BCS121 can be
set in the countdown-mode. The timer will count down from a set point to 0:00.0. This time
can be entered with the remote control, for example:

[1] [2] [ENTER]

The timer will start counting down from 0:12.0.

TIMER COUNTING UP/DOWN

During an intro of a (music-) item the timer will count down to indicate the (approaching) end
of the intro. When 0:00:0 is reached, the timer switches to indicating the elapsed time from
the point where the timer was triggered. The intro-time can be set from the remote control the
same way, for example:

[1] [2] [ENTER]

The timer will start counting down from 0:12:0 to 0:00:0, then counting up from 0:12:0.

36 BCS50 Technical specifications DATEQ BCS50 user manual EN

TIMER COUNTING DOWN TO A SET TIME

In this mode the timer indicates the remaining time until a set time is reached, for example
the starting-time of commercials and/or news. Enter this time from the remote control unit,
for example:

[1] [7] [5] [7] [3] [4] [ENTER]

...to count down to 17:57:34. There is an important distinction between this mode and the
other modes. This mode can be run in ‘background’, independent from the other timer­modes. Once the set-time is programmed, the timer can be started, stopped and reset in all
other modes, while the countdown timer keeps running. If you switch back to this mode, the
remaining time will be displayed again.

In case the set time is approaching with the timer in a different mode, a small blinking dot is
displayed on the left of the timer-display for the last 30 seconds, to draw the users attention.

INPUT-MASK-MODE

For external triggering of the timer 8 switch-signals can be connected to the BCS121. Since it
is not always desired to trigger the timer with all connected signals, each signal can be
individually blocked out with the mask-option. In the initial situation all inputs are enabled, so
the display will show ‘1234/ 5678’. With the [1] .. [8] - keys of the remote control unit each
channel can be disabled or enabled. For example by pressing

[3] [5] [6]

the display will show ‘12-4 / --78‘. This means channels 3, 5 and 6 are disabled. Inputs 1, 2, 4,
7 and 8 are enabled.

Please note that the BCS70 uses input 1 and 2 to control the timer, so only inputs 3 through 8
are available for user-specific signals. You should always have input 1 enabled. Input 2 can
be enabled or disabled to use the timer in two different operating modes. If you enable input 2,
each channel on the BCS70 which is configured to control the timer (by means of the RES
setup-option) will restart the timer as soon as the channel is opened. If you disable input 2,
the timer will run as long as there is at least one open channel on the BCS70 with the timer
control setup-option selected.

Setting the time

During normal reception-conditions the clock will be synchronised within 2 minutes, and the
right time will appear on the display. It is also possible to use the clock with the antenna not
connected (‘free running’). In this case setting the clock to the right time can be done by
entering the time from the remote control unit, by pressing [0] [0] [0] when in input mask
mode. When this is done, ‘ / SEt ‘ will appear. For example:

[1] [7] [2] [8] [0] [0] [ENTER]

The clock starts running from 17:28:00.
When the clock is a little slow or fast it can be synchronised by pressing the [C] key at the

whole hour when the timer is in counting-up-mode. This function is only available when no
valid DCF-signal is received and the time-deviation is less than 3 minutes.

This function is available when your clock has firmware version 1.5 or higher. To check your
firmware version go to the input-mask-mode and press the [C] key!

Address 3 remote control

BCS121 antenna

The cable of the supplied DCF77-antenna can be extended without any problem (up to a
maximum of 100 meters, 300 feet). Mount the aerial in a position where reception quality of
the DCF77-transmitter is good. Be aware of the fact that the direction of the antenna is
important. If the reception of the transmitter is good, the LED on the aerial will blink every
second on a regular basis. If the LED doesn't blink, or blinks irregularly, reception is bad. The
cause for a bad reception can often be found in computer-equipment nearby, or steel
constructions in the building, blocking the long-wave signal of the transmitter.

CAUTION: The supplied antenna is not suitable for outside-mounting. The antenna is not
waterproof, and the built-in electronic circuit will not operate properly below the freezing point
and above 50 degrees Celsius.
