Using This Manual
Please Read This! - Using This Manual
This manual has been written to make the understanding and
operation of the FPC-900 Remote as easy as possible. Because the
FPC-900 is a relatively sophisticated software product, we have
included several ways to find the information you require in this
manual, some of which are new. You will have already found a Quick
Reference on the previous page to get the user going from scratch.
These instructions are by no means all there is to know and references
are made to the main body of the manual for extra detail.
The Contents now begins on Page 3, opposite this one. The chapter
and section names are generally those of the important Keys and
Controls on the Remote. This is a good place to find whole sections,
for example Events or Recall.
Once you have found the appropriate chapter there is often a Quick
Reference section. This will give abbreviated instructions for the use of
the key or control. These can remind the user of a control’s operation
if the section has already been read.
Throughout the text there are references to other areas in the following
form.
Refer to Section 3.1 ‘Basic Controls’ - Display.
These will help to tie together different places where the same keys are
used for different purposes. They are also used heavily in Section 3.0
‘Basic Controls’....
Section 3.0 has several drawings of front and rear panels of both the
remote and the Interface. Each are annotated and reference to the
appropriate letter will give a brief description of the item and usually a
reference to the section in the manual where the item is detailed at
greater length.
Finally, when you need to refer to a particular feature quickly, the
Index may be the quickest way. The Index can be found at the end of
the manual, after the appendices.
Please feel free to give us your comments on this manual and any
ideas you may have for further improvement. Although we make every
effort to ensure that this manual is correct, there may have been recent
improvements made in the software which are not reflected in this
release.

1.0 Introduction
The FPC-900 is a portable, wireless remote controller for the FCS-926
and FCS-920 Varicurve Equaliser units and the FDS-388 Omnidrive PA
controller. It offers sound engineers and contractors unparalleled
flexibility and efficiency in the calibration and control of distributed
array systems, and programmable multiband parametric EQ for up to
32 audio channels.
Communicating via a supplied multiway cable, a standard radio-mic
link or an XLR tie line, the FPC-900 allows the operator to address a
network of up to 16 FCS-926/920 Dual VARICURVE Equaliser
Analyser units and FDS-388 Omnidrive PA controller and crossover
units from anywhere in an arena, stadium or installation venue.
The intuitive control surface provides familiar rotary control of EQ and
RTA parameters in real time with instant selection of functions via a
unique Speed Strip touch pad.
The FPC-900 can control all of the features of the VARICURVE units
and, in addition, can Group several VARICURVE units to be controlled
simultaneously.
The FPC-900 can control the gain, mute and delay variables within an
FDS-388 Omnidrive controller.
For show time, an Events system can command user-defined
sequences of Midi program changes mapped to VARICURVE
Equalisers or other non-BSS Midi controlled equipment such as effects
processors and routing matrices.

2.0 Installation
As part of BSS Audio’s policy of quality control, this product is
carefully checked before packing to ensure flawless appearance and
that it reaches you in first class condition.
After unpacking the two units, please inspect them for any physical
damage. If any damage has occurred, notify your dealer immediately.
A written claim for damages can then be initiated. The Warranty at the
end of the manual gives more information (see section 18.0).
Please retain the shipping carton and all the packing materials for use
should the unit need to be transported or returned for any reason.
The FPC-900i interface requires a vertical rack space of 1U (1.75" or
44mm). The unit should be supported at its rear by additional bracing
or shelving if it is to be used in a transportable system. Failure to do so
will impair the reliability and may possibly invalidate the warranty.
Figure 2.1 details the relevant dimensions and fixing centres for the
FPC-900i.
Adequate ventilation must be provided by allowing sufficient space
around the sides and rear of the FPC-900i to ensure free circulation of
air. Forced cooling is not required.
The FPC-900r remote is intended to be portable and has no particular
mechanical requirements. Care should be taken to ensure that the
remote is properly cushioned in transit. The unit should be kept in the
carry case provided and transported securely to prevent movement and
heavy impacts. Figure 2.2 details the overall size of the FPC-900r.

Before connecting the FPC-900i interface to an AC power source,
check that the voltage selector switch on the side panel is correctly set.
If a change is necessary then ensure that the mains fuse is changed for
one of the correct current rating
Refer to Section 2.6 'Installation' - AC Power and Fusing.
2.3 Mains Power
As the colours of the wires in the mains lead may not correspond with
the markings identifying the terminals in your plug, proceed as follows.
!The wire which is coloured Green and Yellow or Green must be
connected to the terminal which is marked with the letter ‘E’ or by
the Earth signal or which is coloured Green and Yellow or
Green.
"The wire which is coloured Blue must be connected to the terminal
labelled ‘N’ or coloured Black or Blue.
#The wire which is coloured Brown must be connected to the
terminal labelled ‘L’ or coloured Red or Brown.
Those units supplied to the North American market will have an
integral moulded 3 pin connector which is provided to satisfy required
local standards.

The mains voltage selector switch provides a simple external adjust-
ment to allow operation on all international AC power standards.
Newer units are supplied with 115/230V selector switches. The allow-
able ranges for the supply voltage are:
90VAC up to 132VAC on the 120V or 115V position and
190VAC up to 264VAC on the 240V or 230V position.
Outside these voltages the unit will not work satisfactorily, if at all.
Voltages in excess of the maximum will probably cause damage.
Voltages below the minimum will cause the power supplies to drop out
of regulation, degrading the performance of the system. The battery
pack in the remote will preserve all data in the event of a power failure.
The Green and Yellow wire of the mains cord must always be con-
nected to an installation Safety Earth or Ground. It is essential for per-
sonal safety as well as the correct operation of the system, and is inter-
nally connected to all exposed metal surfaces. Any rack framework into
which this unit may be mounted is assumed to be connected to the
same grounding circuit.
The incoming mains power is fused within the FPC-900i by the fuse
holder mounted on the rear panel. Should it be necessary, the fuse must
be replaced by one of the same size and current rating.
20mm T200mA for the 240V o r 230V setting
20mm T315mA for the 120V or 115V setting
It is most important for continued safety that this specification is strictly
adhered to. Spare fuses of the correct rating are supplied with the unit
from new.
It is unlikely that the AC fuse will fail during normal use and caution
should be exercised if it does. The most likely reason at first power up is
the incorrect setting of the mains voltage switch on the side panel.
Another reason may be the connection of the unit across two lines of a
three phase supply. In both of these cases the internal transient suppres-
sors may have been damaged and will continue to blow replacement
fuses, even if the supply is now correct. The suppressors will have
protected the FPC-900i from damage and need replacing before the
interface can be used again. Refer to section 19.1 for the replacement
procedure.

Quick Reference
Connect MIDI Outs to MIDI Ins in a daisy chain back
to the Interface. Set FCS-926s and FCS-920s to
different MIDI channels, and set FCS-926s to MIDI
XMIT THRU. Connect the Remote - Interface umbilical
then execute UTILS/XFER/DUMP ALLDEV to REMOTE.
The 5-way XLR umbilical cable which normally connects the FPC-900r
remote to the FPC-900i interface provides power for the remote,
charges the internal lead-acid battery, and provides two-way
communication. Data emanating from the remote is passed on by the
interface to the MIDI Out socket for distribution to the various BSS
devices. The remote also requests data back from the devices so that
updated parameter values can be checked to eliminate the chance of a
communications error causing a difference between what is displayed
on the remote, and what is active on the device. For this to happen,
the remote must be able to talk to any device, and any device must be
able to talk to the remote. This is achieved by the Varicurve equalisers
and Omnidrives operating in a ‘soft thru’ mode, where any received
data is passed on to the MIDI Out, but if the device is required to talk,
it can do so by injecting data into the stream.
Figure 2.3 shows how multiple units should connect together on a
MIDI loop. Connect MIDI Out of the FPC-900i Interface to the MIDI In
of the first device, then MIDI Out to MIDI In etc to all the remaining
devices in a daisy chain. Connect the final MIDI Out back to the
Interface MIDI In. Set all the devices to different MIDI channels, and
set their MIDI XMIT mode to THRU. Connect the 5-way umbilical
cable between the remote and interface. When power is applied to the
system, the display of the remote will energise, and a startup message
will appear. If a meteorology probe is used on an FDS-388 Omnidrive
then it should be connected to the first FDS-388 in the loop after the
FPC-900i MIDI Out. Set the METEOROLOGY variable on the FDS-388
to METEOROLOGY AUTO on the unit fitted with the meteorology
probe and to METEOROLOGY MIDI on the following FDS-388s on the
loop.

Since the remote stores within it all data concerned with each
Varicurve unit, it is first essential to dump all data from the Varicurves
to the remote. Data for Omnidrives is only stored in the Omnidrive
itself. To initiate this process, use XFER ALLDEV to REMOTE in the
UTILS menu - see section 15.0 'Xfer (transfer)'. This must be done
whenever any device in the system is added, removed or adjusted in
any fundamental way, such as changing the channel access mode. The
automatic device polling which occurs invisibly to the user collects
current parameters from the currently selected device, but does not
collect program data or configuration information, so the user should
not be complacent and expect the remote to follow any changes made
to the device without its knowledge. Rather, the controls on the
Varicurve devices should be left alone once a dump is done, and then
use only the controls on the remote to alter the device settings. In
‘panic’ situations though, the system will tolerate filter parameters
being adjusted on the device controls, which the remote will get to
know about on the next poll, which occurs approximately every 10
seconds.
Up to three series-connected 6m umbilical cables may be connected
together to extend the radius of operation before power losses become
a problem. With a heavier cable however, the cable length may be
increased. A four-core screened cable with 0.5 square mm conductors
will allow a length of up to 50m to be used. If a greater distance is
required, then use the FSK communications (see section 2.8) and the
internal battery.

FSK
2.8 FSK An FSK (Frequency Shift Keying) communications channel is included
for operation over long microphone cables, or over a standard
musicians wireless link. One-way data transmission is then possible,
although the user may notice that the lower data rate results in slower
reaction of the devices to commands issued by the remote.
Using standard microphone XLR cable, lengths of several hundred
metres are quite acceptable. A wireless link however allows not only a
greater operating range, but also more freedom since it is not necessary
to drag cables around. The signal level from the remote is around
0dBu, compatible with the guitar input of a wireless transmitter. The
FSK input of the interface will accept a similar signal level, although
any signal level which lights the SIG LED, but does not light the PEAK
LED will be acceptable. If this is not the case, then adjust the signal
level from the receiver to suit. If the ERROR LED lights, then the signal
may be too noisy or intermittent.

Quick Reference
Connect the umbilical between the remote and
interface so that the charger can keep the battery
charged. Any flashing LEDs on the interface indicate
charge to go. All four LEDs light when fully charged.
Keep the display brightness lower when working
remotely via FSK, and always re-charge immediately
after.
The battery in the FPC-900r remote is a lead-acid type designed for long
life, when subjected to proper charge cycling. Unlike Nickel-cadmium
cells, lead-acid batteries will tolerate frequent light discharges. The
shallower the discharge, the more the life will be improved. The battery
charger in the FPC-900i interface is an intelligent processor controlled
charger which takes care of the battery charge management transpar-
ently to the user. Leave the umbilical connected to the energised Inter-
face all the time the remote is in use if possible. Only disconnect it
when FSK communication is essential, and then only for as long as
necessary. As soon as FSK is finished with, put the remote back on
charge. You cannot overcharge the battery since the interface stops
charging when the battery is fully charged. The CHARGE LEDs on the
interface show the charge progress. On an exhausted battery, all four
will flash.
As the battery charges, the CHARGE bargraph will ‘fill-up’ with lit LEDs,
while the top ones flash to show charge to go. When the battery is fully
charged, all four LEDs will be on and none will flash. Whilst connected
to the interface, the battery bargraph meter on the remote will show the
same charge progress as the interface. When the remote is working on
battery power, the battery meter shows life remaining, which are not
the same. If the FAULT LED should light on the interface, then this
could indicate either a battery malfunction, or that the fuse inside the
remote has ruptured.
When working remotely via FSK, the battery is the only source of
power. The main consumer of power in the remote is the display
backlight, so to preserve life, the display brightness should be kept as
low as is acceptable. Typically, a freshly charged battery will give
approximately 40 minutes of use when the display is at full brightness,
whereas at minimum brightness, up to 3 hours can be expected. When
the remote is powered from the interface via the umbilical, it is ener-
gised continuously, and does not switch off. Under battery power
however, the remote is energised by pressing the ON button momentar-

ily. The unit will remain energised for approximately 30 seconds after
which it will switch off automatically, unless a control is moved, which
starts the timer for another 30 seconds.
As time progresses, the battery meter will gradually empty, until ulti-
mately, unless the user recharges the battery, the meter will empty,
soon after which the display brightness will automatically dim to con-
serve power, and ultimately the unit will switch itself off so that suffi-
cient charge is retained to keep the internal memory energised.
Never leave the battery in a discharged condition for long periods
otherwise the memory contents may be lost, and the battery may suffer
irreversible damage. As soon as possible, re-charge the battery. If the
remote is to be stored for an extended period, make sure that the battery
is fully charged.
