Quick Guide Overview
VPL - Voltage Peak Limiter adjustment is provided for 8 individual levels. Select the setting most appropriate
for connected speakers. See Appendix for details.
Mode - Select VPL mode between Hard and Soft. For channels driving sub-woofers and low-end frequencies,
it is recommended to use the Hard setting for optimal operation. For mid- and high-frequency drivers, always
select Soft.
GPI 2 Level Trig - Disables GPI 1; GPI 2 turns amplifier on when closed, off when open. (See section 7.5).
GPI (➝ NomadLink) - Disables the amplifier’s connectivity to the NomadLink network.
4.3 NomadLink / Ethernet network setup
The amplifier includes, as a standard feature, internal facilities for the NomadLink monitoring and control
network. All features of the NomadLink network are accessible via a PC running Lab.gruppen’s proprietary
DeviceControl software. A single rackspace NLB60E NomadLink Bridge & Network Controller, the NLB 60E,
accepts the TCP/IP data stream from the computer and converts it to the NomadLink protocols. Even when no
computer is connected, the NLB 60E can initiate stand-alone power ON/OFF and muting functions, as well as
report any fault or warning condition.
The PC is connected to the NLB 60E using a standard Ethernet interface and a crossed Cat-5 cable (peer-
to-peer setup). If a HUB or switch is in the network, standard “straight” Cat-5 cables must be used. The front
and rear Ethernet connections on the NLB 60E can be used individually, but only one PC at a time running
DeviceControl can access the network.
Many newer laptop computers will allow peer-to-peer
connection with the NLB 60E using a standard
“straight” Cat-5 cable instead of a crossed cable.
The default fixed TCP/IP address of the NLB 60E is 192.168.1.166. The subnet mask is 255.255.255.0. For
further system configuration details, please refer to instructions supplied with the NLB 60E unit.
The NomadLink connections between amplifiers use standard “straight” Cat-5/RJ45 equipped cables.
US National Differences cl.16.3 requires that
NomadLink network cables must be rated VW-1.
