Conguration
5. Conguration
Before making input, output and GPIO connections,
an initial Danley DSA amplier conguration should
be established. It is particularly important that the
amplier output format is congured appropriately for
the speakers that are to be connected.
Conguration requires that Danley DSA ampliers are
connected to mains power, switched on and connected
to network services. These connections are described in
the following two sections.
5.1 Mains Power Connection
Danley DSA ampliers incorporate a power factor corrected
power supply and can be used with mains input voltage from
100V AC to 240V AC, 50/60Hz. Use the mains cable supplied
with the amplier and connect it to a mains supply.
Press the front panel power button to switch on the amplier.
After a short delay the front panel Status indicator will
illuminate green.
5.2 Network Services
Danley DSA ampliers are congured via the Control
Web App interface. Before the Web App conguration
menus can be accessed, Danley DSA ampliers must be
connected to the same TCP/IP network as the computer
or mobile device that is to be used for conguration.
5.2.1 Wired (Ethernet) Network Connection
To connect a Danley DSA amplier to a TCP/IP network using a
wired connection (Ethernet) follow the steps below.
1. Use an Ethernet cable to connect the Danley DSA amplier
rear panel Network Control socket to a free socket on a
network router or switch, or directly to an Ethernet equipped
laptop or desktop computer.
2. Connect the Danley DSA amplier to mains power using
the supplied mains cable. Wait for the front panel Network
indicator to illuminate green to indicate that the amplier has
network connectivity.
3. The Danley DSA amplier default LAN IP address is
192.168.64.100. Congure the laptop or desktop computer
for a xed IP address in the same IP range; eg. 192.168.64.10,
with Subnet mask of 255.255.255.0 (or prex 24) and set the
Gateway to 192.168.64.1.
4. Open a laptop or desktop web browser and enter the address
http://192.168.64.100. The Control Web App interface will
open to enable amplier conguration as required.
Note: Danley DSA ampliers can be congured to use DHCP for
network connection if required. However, if a Danley DSA amplier
using DHCP is power cycled, it is possible that the TCP/IP network
router will assign it a different IP address, leaving its conguration
page inaccessible via the previous address. If this occurs, a network
scanning app can be used to identify the new IP address. DHCP and
Fixed IP address option settings can be found in the Settings Tab
menu described in Section 5.3.
5.2.2 Wireless (WiFi) Network Connection
To connect a Danley DSA amplier to a TCP/IP network using a
wireless connection (WiFi) follow the steps below.
1. With the Danley DSA amplier connected to mains power,
wait for the front panel WiFi indicator to illuminate green.
2. Use a mobile, laptop or desktop device to search for available
WiFi networks. Connect to, Danley DSA (product serial
number)’ using the password, ‘password’. The amplier serial
number can be found on its rear panel.
3. Open a computer or mobile device web browser and enter
the IP address: 192.168.4.1. The Control Web App interface
will open to enable amplier conguration as required.
4. Select the Web App Settings Tab followed by WiFi > WiFi
Mode > Client to congure the amplier to connect to the
required WiFI network. The WiFi network name and password
will be required.
It is strongly recommended that the Danley DSA amplier
Access Point WiFi password is changed following initial
wireless connection.

5.3 Conguration Menus
Opening a web browser that is network connected to a
Danley DSA amplier initially displays the Control Web App
Dashboard illustrated in Diagram 5a. The Dashboard is the
‘home’ page from which all other conguration options can be
accessed.
The Dashboard displays the amplier status, output zones and
the conguration menu tabs. It also enables immediate access
to zone volume control The functions available under each
conguration menu tab are described in the following sections.
Conguration
5.3.2 Zone Tab
The Zone Tab enables installation zones to be dened and
named, and provides access to further sub-menus. Zones
might be bar or restaurant areas for example, or different
rooms in a home. For all Zone Tab menus, the installation zone
under conguration is selected by highlighting one of the zone
identiers (A, B, C or D) at the top of the page. Diagram 5c
illustrates the Zone Tab.
• The Source menu option enables inputs to be assigned to
zones.
• The GPIO Volume Control option enables external volume
control to be applied to individual zones. The GPIO
conguration menu can be found under the Settings Tab.
• The Compressor option enables default or custom signal
compression to be applied to individual installation zones.
Note: Compression can be useful to reduce the volume difference
between loud and quiet audio material. The lower the compression
threshold is set, the more the difference between loud and soft will
be reduced. The overall zone volume may need to be increased
when compression is used. The default compression parameters are
appropriate for most installations.
5.3.3 Output Tab
The Output Tab enables amplier outputs to be named and
provides access to further sub-menus. For all Output Tab
menus, the amplier output under conguration is selected
by highlighting one of the output identiers (1, 2, 3 or 4) at the
top of the display. The Output Tab also enables Speaker Preset
congurations to be created, exported, imported or cleared.
Diagram 5d illustrates the Output Tab.
Note: The number of individual outputs available for conguration
will depend on the Danley DSA amplier model and the input, zone
and output mode conguration.
• The Routing menu enables zones to be assigned to amplier
outputs.
Note: Routing for zones specied as stereo will automatically offer
three output options: left channel, right channel or summed mono.
The summed mono signal can potentially be used to drive a mono
subwoofer.
• The Delay menu enables delay to be applied to individual
amplier outputs.
• The Equalizer menu enables parametric equalization to be
applied to individual amplier outputs. Equalizer settings
congured for one amplier output can be copied and
applied to other outputs.

Conguration
• The Speaker Preset menu enables a set of speaker
parameters to be adjusted, and preset congurations to be
created.
• Speaker Presets can be simply applied to the selected
amplier output or imported, chosen from a library,
exported or cleared. The preset congurations can include
any or all of the parameters described in Section 5.3.4
and can be locked to prevent inadvertent modication.
Diagrams 5e to 5h illustrate the application of speaker
presets.
Speaker Preset data provided by third parties for use with
specic speakers can be imported and applied to amplier
outputs. To import speaker preset parameters follow the
steps described below and illustrated in the diagrams.
1. Select either the IMPORT PRESET FROM FILE or
SELECT PRESET FROM LIBRARY option from the
Speaker Preset menu. If no import option is visible,
select CLEAR to delete any existing speaker preset
data.
Note: The SELECT PRESET FROM LIBRARY option will be
unavailable if no speaker preset libraries have been created. Speaker
preset library creation and management is described in Section
5.3.5.
2. Select the appropriate ‘.zcp’ format speaker preset
data le to import from either a Library or a
computer folder. The preset data will be applied
to the selected amplier output as soon as the le
import is complete.
3. If the Speaker Preset data requires modication it
can be customized by selecting the CUSTOMIZE
PRESET option.
Note: If an imported Speaker Preset data le includes locked
parameters, they will be unavailable for modication.
5.3.4 Speaker Preset Menu Parameters
• The Crossover & Gain preset menu enables high or low-
pass crossover lters and gain adjustment to be applied to
individual amplier outputs.
• The Speaker EQ preset menu enables parametric
equalization to be applied to individual amplier outputs.
• The FIR preset menu enables FIR (Finite Impulse Response)
based equalization lter coefcients generated by external
speaker measurement software to be imported and applied
to individual amplier outputs.
Note: FIR coefcient les in either .csv or .txt format can be
imported.
