IMPORTANT
NOTE
In order to ensure a good operation of BC-2000 D system a simple maintenance must be done.
In the case of the BC2000DF type chassis, there are 10 fans located on the top that must be
kept clean. We recommend to check fans operation at least once a year.
In the case of using ventilation units combined with BC2000DF-3 type chassis, we also
recommend to keep fans clean and check their operation at least once a year.
It’s also important to keep clean the air holes of rear boards and front cover, as well as the
boards connectors.

1. Introduction: Organization of BC-2000 D system manuals.
More than just a product, the BC-2000 D is a System that must be known at different levels by
different types of technicians and users. This is why the information we are providing you is
structured in different documents, oriented to different professional profiles.
1. BC-2000 D console catalogue. For all professional profiles involved in the purchase
and use of the BC-2000 D as a mixing console: prescriber, installer, technical manager,
administrator and user.
2. BC-2000 D matrix/multiplexer catalogue. For all professional profiles involved in the
purchase and use of the BC-2000 D as a switching matrix/audio and data multiplexer:
prescriber, installer, technical manager, administrator and user.
3. Hardware Manual (this manual). For the professional profiles involved in the installation
and technical knowledge of the BC-2000 D as a mixing console or switching
matrix/audio and data multiplexer: prescriber, technical manager, installer and
administrator.
4. ARENA DM control surface User’s Manual. Aimed directly at the user of the BC-2000
D as a mixing console, although this manual should also be known at a more basic level
by the rest of the professional profiles involved with the BC-2000 D as a mixing console:
prescriber, installer, technical manager and administrator.
5. Configuration software for the BC-2000 D mixing console User’s Manual. This is
the fundamental tool for the administrator, and is also highly useful for the mixing
console prescriber, installer and technical manager.
6. Firmware upgrade software User’s Manual. This is a tool meant specifically for the
installer and maintenance technician, it can also be used by the administrator under
technical department supervision.
7. Configuration software for the BC-2000 D matrix/multiplexer User’s Manual. In the
use of the BC-2000 D as a switching matrix or audio and data multiplexer, the
demarcation of roles between technical and user profiles is not that clear. Therefore,
this manual and the next one should be known by the various technical profiles
involved; in some cases, some material can be extracted from the user’s manual for the
benefit of low-level users.
8. Real Time Control software for the BC-2000 D matrix/multiplexer User’s Manual.

2. BC2000DF / BC2000DF-3. System rack.
General description.
This is the chassis that houses the BC-2000 D system printed circuit boards. It is 4 units high
and 19” deep. The backpanel and the TDM bus terminal board are integrated into the rack, as
well as the system cooling fans (only for BC2000DF chassis).
Composition of the supply.
•Rack with the relevant boards.
•4-meter speakon/speakon power supply cable.
•1-meter flexible, shielded, uncrossed local network cable (for connection through
switch).
Description of the panels.
The front section has 21 slots. The first of these (“A“in the figure below) must be occupied by
a load termination board, and the next 20 slots (“B“) can accommodate up to 20 DSP boards
(BC2221). At the right-hand end of the rack (“C“) a BC2250 front control panel could be placed:
when this front module is mounted in the system, the rack can accommodate up to 18 DSP
boards.
The rear section offers 21 slots (“D“ in the drawing below) to house up to 16 input/output
boards (BC2201, BC2202, BC2203, BC2204, BC2205, BC2206, BC2207, BC2208, BC2209,
BC2210, BC2211, BC2212, BC2312, BC2213, BC2214, BC2224, BC2215, BC2216, BC2217 or
BC2219) and 1 or 2 power supply modules (BC2292). When there are no BC2292 modules in
the system, the rack can accommodate up to 21 input/output boards. There are two slots at the
left end of the chassis (“E“) to house one or two BC2240 controller modules.

While the boards can be inserted in any position in the rack, we recommend, whenever
possible, leaving an empty slot between each pair of boards inserted in the rear panel to
facilitate connection and disconnection of the cables and ventilation (by convection in
BC2000DF-3 chassis).
Other characteristics and features.
In the case of a BC2000DF-3 chassis, the ventilator fans are mounted so that they can be hot-
swapped. To be able to hot-swap the fans, the rack must be mounted on extractor rails.
The backpanel or connection board is completely passive, which eases maintenance.
Backpanel breakdowns or failures are highly improbable and can only occur for mechanical
reasons.
General characteristics.
-Dimensions: 4 U x 19 “ (482 mm x 176 mm x 450 mm).
-Approximate weight: 10,500 grams.
2.1. Ventilation units.
For dense setups with several BC2000DF-3 type racks, it’s necessary to install forced
ventilation units for a better system cooling. There are 3 kinds of ventilation units, depending
on if there are 6 frontal ventilation fans (BC 2000 FAN DOWN), 6 rear ventilation fans (BC 2000
FAN UP) or 6 frontal and 6 rear ventilation fans (BC 2000 FAN MIDDLE).
In a system with several racks placed vertically, one unit of first type (as indicated by its name)
will be placed in the lower part of the system for air insertion and one unit of second type will be
placed at the top of the system for hot air extraction; in addition, between each pair of racks one
unit of third type will be placed in order to extract hot air from the lower rack and insert cold air
in the upper one.
Each ventilation unit has 1 unit high and is feeded with 48 volts DC through a connector with
SPEAKON type interlock. Approximate consumption is 2 watts for simple units and 4 watts for
double units.

LED*:
this LED will turn on when the
system starts and, depending on its status, it will indicate
during normal operation:
- Configured and active board: fast blinking.
- Not configured board: slow blinking.
- Board start error: LED on and fixed.
- Board configured in backup mode: LED off.
'1' RJ45 type connector: 4 analog monophonic inputs
with mic or line level, balanced by transformer.
'3' RJ45 type connector: 4 independent inputs
configurable as general purpose inputs (GPI).
'4' RJ45 type connector: 4 independent outputs
configurable as general purpose outputs (GPO).
* This operation way of 'HW ERROR' LED is valid for 2.23 microcontroller
module firmware version (and later versions).

Other characteristics and features.
-Internal warning signal indicating a failure in one of the power supplies. If a failure occurs, the
“ALARM” LED on the BC2240 controller board will light up.
-Power feed circuit designed to support hot-swapping operations.
-Digital adjustment of analog gain (±12 dB) in the 4 inputs.
-Digital adjustment of digital gain (-40/+24dB) in the 4 inputs.
Programming jumpers.
This board has a series of internal programming jumpers (PJ). However, these jumpers are
configured at the factory and, in normal operation, do not need to be changed.
Firmware modules.
At the firmware level, this board is made up of the following modules:
- PIC microcontroller: manages board communications and start-up.
- FPGA programmable device: manages the converters and the TDM bus.
The firmware versions can be brought up to date by using the ”BC2000D Firmware Upgrade”
software application.
Signal layout in the RJ45 connectors of the board.
NOTE: Pin layout corresponds to T568B standard.

3.5. BC2203MHL. Analog MIC/LIN inputs and headphone outputs module.
General description.
The BC2203MHL board is capable of managing four TDM IN bus time-slots to insert four analog
mono signals into the system with mic or line level, and can furnish 48 volts of PHANTOM
power to the microphones that require it. It also manages four TDM OUT bus time-slots to
extract two signals from the system for two stereo headphones.
This board is inserted into the rear part of the BC2000DF rack, where it occupies two slots.

Programming jumpers.
This board has a series of internal programming jumpers (PJ). By default, this board is
configured to work with high impedance headphones (higher than 150Ω). If you use low
impedance headphones (below 150Ω), you will need to pull the board out and change the J1,
J2, J3 and J4 jumpers on the board marked "472-001-311" to position 2-3.
