Dateq BCS25 manual Introduction
EN
Introduction
The BCS 25 is specifically designed for applications requiring a full-featured mixing console while being
restricted by dimensional and/or financial limits. Post-production rooms, OB vans, on-location transmission
studios and secondary studios are only a few of the possible uses for the BCS 25.
The BCS 25 frame is supplied with 8 input channels (optional with or without equalizer), the build in power
supply and an extensive mastersection with LED PPM's.
Input modules
The universal BCS25(E) input channel features 3 inputs (line 1, line 2 and mic), a gaincontrol, a 3-band
equaliser (option: without) and a balance control. The input signal can be routed to two stereo mix-busses
with the audition and program select buttons. This enables the engineer to set up two different output mixes
or to use the console for two different jobs running simultaneously.
The auxiliary 1 is pre-fader and has a volumecontrol on the module. The auxiliary 2 bus sends the signal
directly to the master section, the signal may be selected pre or post fader.
The cue button enables pre-fade listening of the input source. A fader/button start feature is standard (fader
or button function is set by an internal jumper). The 100 mm fader is not in the audio signal path but only
controls the VCA; this prevents any signal distortion and increases reliability.
Telephone hybrid
There is also a special telephone channel available with integrated analogue telephone hybrid. This channel
can also be used as a remote for an external hybrid. The ON/OFF buttons can be used for the remote
control for the external hybrid.
The BCS26(E) is equipped with an intelligent electronic circuit to generate a mix-minus signal (Dateq’s
unique TDM2). This makes it possible to have more than one hybrid in the mixer.
BCS27 Master module
The master section is extremely well equipped. It has a 40-segment LED VU-meter with peak hold function
that can be linked to PGM out or each of the other sources. In addition the BCS27 has a master fader for
PGM out, an adjustable headphone output for monitoring any signal, level controls for other outputs such as
aux, audition, etc.
Any signal can be selected to the monitor outputs (control room or headphone) by means of the switching
matrix.
The dedicated guest and the presenter outputs have a very practical feature. The engineer is able to send a
different signal mix - than the actual PGM - to each of those two outputs. This enables him/her to perform
simple timesaving 'post-production-during-transmission' type of operations!
Communication between engineer, guest and presenter is completely handled by the console, offering
numerous possibilities. The most interesting one is the ability to rout the communication signal to the PGM
output. This option has been specifically implemented for live on-location (OB) transmissions: it presents a
direct and easy communication channel with the studio engineer while news and commercials are broadcast
from the home base studio!

Phantom power
Non-dynamically microphones usually need an external power supply for its built in pre-amplifier.
If this power has to be supplied by the BCS25, place jumper J1 in the ‘ON’ position. +48Vdc will
be supplied to both signal wires related to the cables shielding.
Jumper J1 is situated on the left side of the bussconnector. The factory default setting for this
jumper is ‘OFF’. See picture below:
Dynamically microphones don’t need a phantom power supply. When the correct cables are used
it will not damage the microphone when the phantom power supply is turned on. So it is not really
dangerous to turn the phantom power on for all types of microphones.
Faderstart/ buttonstart
The BCS25(E) module is able to remote start connected equipment by faderstart, buttonstart or a
combination of these two options. By changing jumpers you easily select one of these settings.
The jumpers for remote start settings can be found at the main PCB above the bussconnector
(jumper J8 and J9, see drawing).
Jumpers J8 and J9 select the type of operation. It is possible to choose between faderstart (figure
1), buttonstart (figure 2) or the fader-switch combinaton (figure 3).

FADER, SWITCH COMBINATION
When the fader-switch combination is selected the connected equipment can be started in two
different ways:
1. Pushing the startbutton when the fader is closed. The connected equipment will start as soon
as the fader is opened.
2. Opening the fader. The connected equipment will start as soon as the button is pressed
To start the connected equipment 2 conditions have to be fulfilled. When just one of the
conditions is fulfilled the LED in the button will light up dimmed to indicate that the equipment will
be started as soon as the fader is opened/ the ON is pressed.
The equipment will stop as soon as the button is pressed or the fader is closed.
Remote control output
The BCS25(E) module can generate a continues or pulsed start/stop signal. Jumper J13 at the
main PCB (above the bussconnector in the middle) selects between a continue- or pulse signal at
the remote output.
In the pulse position the remote outputs will generate a pulse of 100msec. When the continues
mode is selected the on-output will provide a high level signal when the channel is switched on
and a low level signal as soon as the channel is switched off. The remote outputs only work when
line input 1 is selected.
On-air channels
The BCS25 has two on-air groups. This makes it possible to drive an indicator to indicate that the
microphones are opened. The output will be activated when one or more channels that belong to
the on-air group are opened.
With jumper J12 a channel is configured as on-air 1 or on-air 2 channel. When a channel is
configured as on-air 1 the studio output will be muted when the channel is active. The on-air 1
output on the master also will be activated. A channel configured as on-air 2 will not mute the
studio, but only activate the on-air 2 output on the master.

Master-cue
Each channel can activate the master-cue function. When the cue-button is pressed the master
module automatically selects the CUE-bus as input. This function can be activated with J10.
DJ-Mode
In a self-support configuration the control room has to be muted when the microphone is opened.
The announcer has to use a headphone, so that acoustical feedback is impossible.
When jumper J11 is set to DJ, the control room will be muted when the channel is activated, all
CUE-functions will be turned off and the master module will select program or audition,
depending on the routing switches.
Cleanfeeds en Auxiliary bus
The BCS25(E) module contains 2 (mono) bus outputs which can be used to create a return signal
to, for example, an ISDN codec. The signal at these busses is post-fader. At each individual
channel of the console can be selected if they belong to one or both of the cleanfeeds by setting
jumpers J4…J7 in the right position.
In the example below the signal of this channel is send to cleanfeed bus 1 only.
Beside the cleanfeeds the BCS25(E) module has 2 auxiliary busses. The first auxiliary is always
pre-fader. Auxiliary 2 can be switched between pre- and postfader by jumper J2 and J3.

BCS26(E) telephone input module
The BCS26(E) telephone input module is available with or without 2 band equaliser. The module
is equipped with a built-in analogue telephone hybrid. Telephone lines can be directly connected
to this channel. Besides the built in hybrid an external hybrid or talk-show system can be
connected. In that case, the BCS26(E) channel operates as remote control only.
On/Off Switches the (external) hybrid on or off. The green LED will
light up at an incoming ringer signal.

The BCS26(E) module contains 2 (mono) bus outputs which can be used to create a return signal
to, for example, an ISDN codec. The signal at these busses is post-fader. At each individual
channel of the console can be selected if they belong to one or both of the cleanfeeds by setting
jumpers J4 and J5 in the right position.
The first example shows a channel that doesn’t belong to a cleanfeed. The second example
belongs to cleanfeed one and not to cleanfeed two.
The BCS25 had two auxiliary busses. The first bus is always pre-fader; the second bus can be
configured to be pre,- or post fader. This is done with J2 ad J3.

Internal or external hybrid
The BCS26(E) module handles incoming telephone calls over the built-in hybrid, but is also able
to remote control an external (digital) hybrid or talk show system.
With jumper J6, J7 and J1 it’s possible to select the type of operation. Jumper J6 and J7 are used
to switch between the internal or external hybrid, J1 switches the bandpass filter on or off. When
a hybrid with built in band pass filter is connected J1 should be placed in the OFF position.
(The drawing below only shows J1 and J7. J6 can be found above the transformer; see the
autogain drawing at the bottom of this page).
Autogain
The BCS26(E) is equipped with a special feature that reduces the signal from the hybrid by 6dB
when audio is sent from the mixer to the hybrid. This means that the caller is dimmed by 6dB
when the announcer in the studio speaks. This feature improves the side tone reduction with 6dB,
so creating the best possible speech intelligibility. The consequence of this auto-gain feature is
that when the caller and announcer are talking at the same time (“double talk”), the announcer in
the studio will slightly drown the voice of the caller.
This function can be disabled with jumper J13. In the first example the autogain function is
enabled.

TDM²
The hybrid automatically gets the correct N-1 return from the CUE, PGM or AUD bus. This is the
so-called Triple Dynamic Mix-Minus system, shortened to TDM2. Since the BCS26 generates the
N-1 signal itself, separate cleanfeeds are not necessary. The number of BCS26 modules which
can be used at the same time is therefore theoretically unlimited. In practice, the number of
telephone lines which can be used at the same time is limited by the quality of the telephone
hybrids being used.
If AUD is selected as well as PGM, the return from the PGM bus has priority over the return from
the AUD bus.
CUE has the highest priority when the channel is off. As soon as CUE is selected on a BCS26
module, the hybrid gets the return from the CUE bus.
