Connections
6. Connections
Danley DSA amplifier rear panel connections are
illustrated in Diagrams 6a.
6.1 Mains Power Connection
Danley DSA amplifiers incorporate a power factor corrected
universal 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 amplifier.
Danley DSA amplifiers incorporate a front panel mounted
power button. Press the button once to switch the amplifier on
or off.
Ensure that all signal, GPIO and output connections are
made before switching on the amplifier.
6.2 Input Connection
All Danley DSA amplifier models provide four balanced or
unbalanced analog audio inputs and a stereo S/PDIF digital
audio input. Any input channel can be routed to any output
channel. Input routing options can be configured via the
Control Web App
Input Tab
. See
Section 5
of this manual.
Analog Inputs
Danley DSA analog inputs are of line level format with a default
input sensitivity of +4dBu (full output voltage swing/sensitivity)
in all output modes. Depending on the selected sensitivity,
the inputs can handle up to +24dBu without clipping. Input
sensitivity options can be set via the Control Web App
Input
Tab
. See
Section 5
of this manual.
Balanced input connections to the amplifiers are made via male
‘Euro Block’ connectors. Connecting cables to the supplied
female input connectors is illustrated in
Diagram 6b.
Unbalanced input connections to the amplifiers are made via
RCA phono sockets connected in parallel with the balanced
inputs.

Note: Two output amplifier model connection sockets differ only in
the deletion of channel 3 and channel 4 output connectors.
Digital Inputs
Danley DSA S/PDIF stereo digital audio input connections
are made via a single RCA Phono socket. The S/PDIF input is
connected by default to amplifier installation Zones A (left) and
B (right).
Digital Outputs
Danley DSA S/PDIF stereo digital audio output connections are
made via a single RCA Phono socket. The S/PDIF output signal
by default reflects the input to amplifier installation Zones A
and B and is intended to be used for daisy-chaining Danley DSA
amplifiers.
Note: 75Ω RCA Phono cables specifically intended for digital audio
should always be used for S/PDIF connections. Standard Phono
cables can be used but may not result in optimal performance.
Note: The S/PDIF output level is by default set at -10dB to reduce
the possibility of downstream input clipping.
6.3 Output Connections
Output connections from the amplifiers are achieved via male
‘Euro Block’ connectors. Ensure that speaker connection
polarity is correct throughout the installation:
In the case of Lo-Z speaker connections, positive (+) amplifier
terminals should always be connected to positive speaker
terminals and negative (–) amplifier terminals always connected
to negative speaker terminals.
In the case of Hi-Z speaker connections, the two speaker cable
conductors should be connected between the positive (+)
terminal of Output 1 and the negative terminal (-) of Output 2,
and likewise for Outputs 3 and 4.
Output mode options (Lo-Z or Hi-Z) can be configured via the
Control Web App
Input Tab
. See
Section 5
of this manual.
Connecting cables to the supplied female
output
connector is
illustrated in
Diagram 6c.
