6.5 Speaker Cable Gauge
AMP-2500 DSP speaker connection cable gauge
should be chosen appropriately to reflect the type
of installation. The adjacent tables specify the
appropriate cable gauge and maximum cable length
for less than 0.5dB cable loss in Lo-Z mode and
less than 1.0dB cable loss in Hi-Z mode.
6.6 GPIO Connections
If any AMP-2500 DSP GPIO functionality is
required, cables will need to be connected to the
supplied GPIO connector. Connecting cables to
the GPIO connector is illustrated in
Diagram 6F
.
6.7 Network Connections
The AMP-2500 DSP amplifier is a TCP/IP network
connected device that is configured via a web page
based interface. Wired (Ethernet) and wireless
(WiFi) connection options are available. Connecting
the AMP-2500 DSP amplifier to a TCP/IP network
is described in
Section 5
of this manual.
NOTE
The supplied “Euro Block” speaker connectors can
accept up to 2.5 mm
2
/ 14 gauge speaker wire.
The exclamation point printed next to the output terminals of the amplifier is, in addition to the
“CLASS 2 WIRING” text, intended to alert users to the risk of hazardous voltages. Output
connectors that could pose a risk are marked with the exclamation point. Do not touch the output
terminals while the amplifier is switched on. Make all connections with the amplifier switched off.
