is still available; the dynamics modules can be configu-
red to be installed pre the module insert output or post
the insert input. Once the necessary frame PCB‘s and
the additional wiring are installed on particular module
slots, these modules can be upgraded with dynamics mo-
dules at any time. Apart from the TKC-DN, a Compres-
sor-Expander, and combined modules; Compressor-Ex-
pander with PPM meter are available. An upgrade with
the necessary frame PCB‘s and wiring is possible at the
location; however it is more expensive.
Meters
Several different meter versions can be used with all BC4
Broadcast Consoles. While each standard console has a
set of ADT high resolution PPM LED meters included,
which read the program master outputs, the control room
source select and the group outputs, almost any other
signal in the console can be assigned to a meter.
Sources
All modules have configurable meter outputs. With in-
put and group modules, there are usually 4 jumpers that
determine the source signal for an external, additional
meter. Channel ouput, pre fader and post fader signals
and the input signal can be selected. With stereo mo-
dules, stereo or mono, external meters are possible. In
addition to the source selection by jumper blocks per
channel, a separate matrix can be used to add a mono
signal for the meter.
The master modules have meter sends for the auxiliary
outputs, the program masters, the control room source
selectors and the PFL master. If no separate PFL meter
is installed, the control room meter can display the PFL
master as soon as PFL is active by automatic switching.

module with the meter frame boards in the bridge.
The location of the meters is not fixed and can be se-
lected by the customer. All meters use a single 24 V
DC supply voltage. A separate supply for the meters
with appropriate capacity is available with each of the
power supply units.
Meter Versions
adt-audio hi-res LED PPM
The TK-PS and TK-PM ADT high resolution LED me-
ters are the standard system for the BC4 consoles. The
meters use 40 LED‘s in a range from +15 dB to -40 dB
with a resolution of 1 dB in the range from +15 to -10
dB and 2 dB down to -30 dB. The release time is line-
arized and can be adjusted to the standard value of
1.5 sec per 20 dB. The attack time is below 1 ms for -1
db display with an burst input signal of 10 ms @ 5 kHz.
The meter is available in stereo and mono versions and
fits into the meter bridge frame boards. It can be used
for all channels and masters of the BC4 system. A corre-
sponding phase correlation meter is also available.
A different scale plate with a display range from + 10
dB to - 45 can be installed alternatively. The level ad-
justment range is more than sufficient to use both sca-
les with all possible nominal levels.
adt-audio 10-LED PPM
An additional, low resolution version with 10 LED‘s
and a total of 30 dB range is available. This is the sa-
me meter that is used with the BC4 input channels in
a format that fits into the meter bridge. These meters
are low cost and can be used for auxiliary send or any
other purpose, alternatively. They are available in mo-
no and stereo configurations.
