C SERIES Operation Manual rev 2.0.0
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 amplier on when closed, off when open. (See section 5.5).
GPI (- NomadLink) - Disables the amplier’s connectivity to the NomadLink network.
4.3. NomadLink / Ethernet network setup
The amplier 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.
NOTE: 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 xed TCP/IP address of the NLB 60E is 192.168.1.166. The subnet mask is 255.255.255.0. For further
system conguration details, please refer to instructions supplied with the NLB 60E unit.
The NomadLink connections between ampliers use standard “straight” Cat-5/RJ45 equipped cables.
NOTE: US National Differences cl.16.3 requires that NomadLink network cables must be rated VW-1.
The OUT port from the NLB 60E must be connected to the IN port of the rst amplier. The OUT port from the rst
amplier in turn connects to the next amplier’s IN port to form a daisy-chain The OUT port on the last amplier is
connected to the IN port on the NLB 60E to close the loop.
