12 C Series Introduction Welcome Thank you for choosing Lab Gruppen C Series power amplifiers for your sound reinforcement system installation. We are confident that you will be very pleased with the performance, configuration flexibility, reliability, and long-term durability offered by the C Series products. This manual provides a comprehensive guide to the features and functionality of C Series model C 88:4, C 68:4, C 48:4, C 28:4 and C 16:4 amplifiers.
14 C Series Quick Start Guide Product Overview 15 (PWR) Power on (Green) Front Panel Overview (PAL) Power Average Limiter active (Red) PAL Option active (Yellow) NomadLink network active (Blue) NOTE: When no VPL, CPL or PAL indicators are illuminated, and the VPL DIP-switch is set to maximum at the specified nominal load, the amplifier channel is able to deliver maximum rated output power.
16 C Series Quick Start Guide 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 NLB 60E NomadLink Bridge & Network Controller accepts the TCP/IP data stream from the computer and converts it to the NomadLink protocols.
18 C Series NOTE: When bridging two channels, you must add +6 dB to the input sensitivity to achieve maximum output voltage due to the automatic -6 dB gain compensation inserted by the amplifier. Quick Start Guide Output operation and connection Screw-terminal connectors with + and – poles are provided at each channel output for connection of the speakers.
20 C Series Constant voltage 70 V and 100 V systems setup and operation When using C Series amplifiers to drive constant voltage (high-impedance) speaker systems at 70 Vrms or 100 V peak, you can in most cases simply connect the speakers to the amplifier output terminals, select the correct VPL setting, and place the amplifier in service.
22 C Series Quick Start Guide It is not possible to adjust the individual channel attenuation from the NomadLink network or elsewhere on the amplifier. NomadLink LED on the rear panel to light up. NomadLink is active even when the amplifier has mains power disconnected or is not yet powered up. Use fingers or a screwdriver to adjust the potentiometers. The amplifier does not have a stand-by power supply for the network. The network is solely powered from the NLB 60E.
24 C Series Appendix Maintenance During normal operation your C Series amplifier will provide trouble-free service. The only user maintenance required is to periodically vacuum clean the foam dust filters behind the front grille. In some extreme cases it may be necessary for authorized service personnel to clean the inside of the amplifier. These conditions usually occur after prolonged use in extreme environments such as those using “cracked oil” smoke machines.
