2. Amplier Overview
Danley DSA125X4 ampliers are half rack width, 1U format
power ampliers that can drive both conventional low
impedance (Lo-Z, 4Ω to 16Ω) loudspeakers and high impedance
(Hi-Z, 70V/100V) transformer coupled loudspeakers. They
provide four analog inputs, one stereo S/PDIF digital input, and
either two or four outputs (Lo-Z mode), or one or two outputs
(Hi-Z mode). Danley DSA ampliers also incorporate automatic
power sharing technology that enables power to be shared
proportionately as required between pairs of outputs in Lo-Z
mode. Danley DSA amplier model output channel counts and
power outputs are as follows:
DSA125X4
Mode Channels Max Rated Output per Channel
Lo-Z Four 125 Watts
Hi-Z Two 250 Watts
Introduction and Overview
2.1 Connections
Danley DSA signal input and output connections are
accomplished via RCA Phono and Euroblock style connectors.
A GPIO (General Purpose In/Out) Euroblock connector enables
some amplier functions to be controlled, and wireless or RJ45
socket Ethernet network connection options are also provided.
Danley DSA ampliers have no mains power switch and are
operational as soon as mains power is connected via the IEC
60320 mains socket.
2.2 Network Features
Danley DSA ampliers are TCP/IP network connected devices
that require a wired or wireless network connection to access
their conguration menus. The conguration menus are
accessed via the Danley DSA Control web app interface and
cover Input, Zone, Output and General Settings functions. The
conguration menus are fully described in Section 4 of this
manual.
2.3 Dimensions
Danley DSA amplier dimensions and features are illustrated
in Diagrams 1a and 1b. The ampliers are primarily intended
for installation in an equipment rack but can also be under-desk
or wall mounted, or used free standing. They are fan-cooled
and must be installed such that ventilation apertures are not
obstructed.
2.4 Firmware
This manual describes the features, functions and user
interface of Danley DSA ampliers running Firmware Version
1.2.0.
It is strongly recommended that the rmware version

4. Installation
Note: The rack mounting and desk/wall mounting components
described and illustrated in Sections 4.1 to 4.3 are not supplied with
Danley DSA ampliers but are available to purchase as accessories.
Contact your amplier re-seller for more information.
4.1 Danley DSA Mounting
The Danley DSA ampliers are shipped without rack mount
hardware attached but can be congured for rack installation
using one standard rack ‘ear’ and one half-rack extension piece
as illustrated in Diagram 3a. The installation and equipment
rack should be congured to provide appropriate ventilation
airow space around the sides and rear of the amplier as
illustrated in as illustrated in Diagram 1a. Ventilation airow
space of at least 25 mm (1 in) should be maintained along at
least one side of the amplier at all times. Ventilation apertures
are also located on the rear panel of the amplier and must not
be obstructed. It is important to retain at least 80 mm (3.1 in)
free space for airow behind the amplier rear panel.
In addition to rack mount ears, optional rack mount rear
support hardware is available and can be attached to the
amplier. Rear support hardware may be appropriate if
the amplier is to be used in a mobile rack or potentially be
subject to signicant movement. Diagram 3b illustrates the
use of rack mount rear support hardware.
Multiple Danley DSA ampliers can also be mechanically
connected using accessory connecting plates. Diagram 3c
illustrates the use of connecting plates.

4.2 Free-standing
If not installed in an equipment rack, Danley DSA ampliers can
be placed free-standing on a at surface. Adhesive rubber feet
are supplied for this purpose.
Danley DSA ampliers can also be attached to the
underside of desks or wall mounted using connecting
plate hardware. The adhesive rubber feet should
also be used in these circumstances to minimise
the possibility of vibration between the amplier
and mounting surface. Wall and desk mounting is
illustrated in Diagrams 4a and 4b.
It is important in any free standing installation that
airow through the amplier’s side panel mounted
fans and rear panel ventilation apertures is not
compromised by adjacent items. At least 80mm of
free space behind the amplier and 25mm along at
least one side should be retained at all times. Mounting Plate +

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 and 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 switched mains supply.
Danley DSA ampliers have no mains power switch and are
operational as soon as mains power is connected.
5.2 Network Services
Danley DSA ampliers are congured via a web page
interface called Danley DSA Control. Before the
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 access.
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 Danley DSA 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 Danley DSA 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.
