DALI PHANTOM CI AMP-2500 DSP amplifier rear panel
connections are illustrated in

.
6.1 Mains Power Connection and
On/Off Switch
The AMP-2500 DSP amplifier incorporates 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.
Press the power button on the front panel once to switch
the amplifier on or off.
6.2 Amplifier Input Connection
The AMP-2500 DSP amplifier provides four balanced or
unbalanced analogue 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 DALI PHANTOM CI AMP CONFIGURATOR web
interface. See
Section 8
of this manual.
Analogue Inputs
AMP-2500 DSP analogue 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 AMP CONFIGURATOR web interface
[Input] Tab
.
See
Section 8
of this manual.

AMP-2500 DSP rear panel connections.
Balanced input connections to the amplifier are made via
male “Euro Block” connectors. Connecting cables to the
supplied female
input
connectors is illustrated in
Diagram
6D
.
Unbalanced input connections to the amplifier are made
via RCA phono sockets connected in parallel with the
balanced inputs.
Digital Inputs
AMP-2500 DSP S/PDIF stereo digital audio input
connections are made via the [DIGITAL IN] RCA Phono
socket. The S/PDIF input is connected by default to
amplifier installation Zones 1 (left) and 2 (right).
Digital Outputs
AMP-2500 DSP S/PDIF stereo digital audio output
connections are made via the [DIGITAL OUT] RCA Phono
socket. The S/PDIF output signal by default reflects
the input to amplifier installation Zones 1 and 2 and is
intended to be used for daisy-chaining AMP-2500 DSP
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.
