Introduction
Your DC1048 is a 4 input, 8 output audio processor, offering a selection of flexible
features to configure and manage an installation audio system. These include
matrix mixing of all inputs to outputs, input equalisation, output equalisation,
output (speaker) crossovers, delays and speaker protection (limiters).
Input signal path:
Output signal path:
Each of the 4 inputs enters the mixing matrix and
is routed to any of the 8 outputs as required
through the adjustment of the relative levels:
Computer and network connections for remote
control are catered for through a front panel USB
socket and an RS485 multi-drop bus connector on
the rear panel.
The simple user interface on the unit helps quickly
set up the various basic comms options to facilitate
connection to a computer for full, secure access to
all the features and easy programming through
ICORE, the software package designed for use
with this and many more products.
Configurations can be saved within the unit for recall as required, either directly
from the front panel, or via the computer. real time clock is also built into the
device so automated recalls at specific times/days can be set-up for complete set-
and-forget operation.
GPIO port allows simple remote preset recall, as well as connection to the
WP-1048 touch remote wall panel.

Operator’s Manual DC1048 Integrated Audio Management Page 11
Installation
Electrical Considerations
The DC1048 has been manufactured to comply with your local power supply
requirements but, before connecting the unit to the supply, ensure that the
voltage (printed on the rear panel) is correct, and that a mains fuse of the correct
type and rating has been fitted.
If the unit’s GPIO terminals are not terminated with screened cables fast rising
transients from extreme RF fields, or ESD strikes over 4000 volts may cause
disturbance to the status LEDs on the unit. This will not affect audio performance
and will be corrected on the next power up cycle.
Make sure power outlets conform to the power requirements listed on
the back of the unit. Damage caused by connecting to incorrect AC
voltage is not covered by the warranty.
Mechanical Considerations
To ensure that this equipment performs to specification, it should be mounted in
a suitable rack or enclosure.
When mounting the unit in a rack or enclosure, ensure that there is adequate
ventilation. The cooling fan sucks cool air in through the LHS and blows warm air
out of the RHS of the unit through the ventilating grills.
Take care when mounting other equipment in the same rack.
Please also refer to the maintenance section on page 56 of this manual.

Page 12 DC1048 Integrated Audio Management Operator’s Manual
Operation
Read all documentation before operating your equipment and retain all
documentation for future reference.
Do not spill water or other liquids into or on the unit and do not operate the unit
while standing in liquid.
Do not block fan intake or operate the unit in an environment that could impede
the free flow of air around the unit.
If the unit is used in an extremely dusty or smoky environment, it should be
cleaned of any collected debris at regular intervals. (Please also refer to the
maintenance section on page 56 of this manual.)

Front Panel Indicators
1: “System” Menu Button
Press this button repeatedly to cycle through the general menu options concerned
with the general operation of the unit – see page 16 for list of options. Options
are changed with the UP/DOWN keys and confirmed with OK. Menu exits
automatically five (5) seconds after the last key is pressed.
2: “GPI” Menu Button
Press this button repeatedly to cycle through the menu options concerned with
the setting up any General Purpose Interface connected to the unit– see page 16
for list of options and more details. Options are changed with the UP/DOWN keys
and confirmed with OK. Menu exits automatically five (5) seconds after the last
key is pressed.
3: “Comms” Menu Button
Press this button repeatedly to cycle through the menu options concerned with
the remote control operation of the unit – see page 16 for list of options. Options
are changed with the UP/DOWN keys and confirmed with OK. Menu exits
automatically five (5) seconds after the last key is pressed.
4: Input Metering
The input meters read the level immediately post analogue to digital converter
( DC) and pre-signal processing (DSP). s such, they will indicate if the input
level is clipping the DC before any processing has been applied. If the clip LED
is illuminated on any particular channel, reduce its level so that the –3dB LED
lights on peaks. If all four CLIP LEDs illuminate, this indicates DSP clipping –
check for excessive EQ filter boost on all channels.
5: LCD Status Display
By default, the LCD shows the current time and date, along with the name of the
last recalled preset. Brightness of this display is automatically reduced when the
unit is not being accessed after a preset time, adjustable under the “System”
menu, along with the contrast.

Remote Control and Initial Set-up
Overview
s the DC1048 is designed for installation applications, the control and set-up of
all audio related parameters is performed under remote control using a PC or
laptop running ICORE. Please ensure you have downloaded the latest release
of the software from our website, xta.co.uk, and have it installed on the
computer.
There are various methods of connecting the unit to a computer. The simplest is
via the USB socket on the front panel of the unit. Units may be cascaded to form
a network using the RS485 connections on their rear panels. The first unit will
relay information from the USB to the RS485 if required or, if the first unit cannot
be located near the computer, a direct RS485 connection can be made to all
units, using a suitable converter.
These three scenarios are explored in more detail in the following pages.
Direct USB Connection
Using a standard USB cable, a serial link can be established to any individual unit.
This connection is also used for upgrading the unit’s firmware which cannot be
done via an RS485 connection. Attempting to do so may cause your unit to
function incorrectly and result in it having to be returned to the factory!
For more information about upgrading firmware, please see the section on page
43 of this manual.

Set the options in the unit’s COMMS menu according to the diagram, that is
Master, ID 1.
Baud rate in the COMMS menu only affects the RS485 network, and the USB
comms speed is fixed at 115200 (or 115k) so if using USB connection make sure
baud rate at the PC is set to 115200.
The first time the USB cable is plugged into the PC, Windows will recognize the
connection of new external hardware (a USB-Serial device) and prompt for device
driver to be installed.
This may be obtained from our website, or directly from the Internet at this
address:
http://www.ftdichip.com/Drivers/VCP.htm
Choose the virtual COM port (VCP) driver as appropriate to your operating
system.
Note that, due to the nature of the USB protocol and the “hot swapping” nature of
the system, if the unit is not powered up and plugged into the PC, the COM port
connection will not be available.
Please confirm that the connection is made and the unit is on before continuing.

Operator’s Manual DC1048 Integrated Audio Management Page 19
Having physically connected the unit, and installed the driver successfully, we
now need to check the virtual COM port that’s being used so we can match this
with the COM port in ICORE.
With the lead plugged in (the COM port won’t show up if the unit isn’t
connected AND powered up!), use the shortcut of the Windows
TM
key on your
keyboard + the Pause/Break key to bring up the System properties window:
Press BOTH keys together! lternatively you can get to the same place through
start  Settings  Control Panel  System
Press the “Hardware” tab and then “Device
Manager”. This will bring up a window with a list of
all hardware subsections of your computer,
including the COM ports. Expand the section
entitled “Ports” and locate the USB-Serial adapter.
The COM port number it has been assigned is in
brackets after the name.
Make a note of this port number and then start ICORE.

Page 20 DC1048 Integrated Audio Management Operator’s Manual
