2 WELCOME 2.1 Introduction Thank you for choosing Lab.gruppen FP+ Series power amplifiers for your sound reinforcement system. We are confident that you will be pleased with the performance, configuration flexibility, reliability, and long-term durability offered by the FP+ Series products. This manual provides a comprehensive guide to the features and functionality of FP+ Series amplifiers.
WELCOME 2 Following are short descriptions of standard built-in FP+ Series protection features: ▸▸ ▸▸ ▸▸ ▸▸ ▸▸ ▸▸ ▸▸ ▸▸ CPL, (Current Peak Limiter) ensures that the amplifier’s output does not exceed the safe current handling parameters of amplifier components. Temperature protection ensures that the amplifier will not be damaged by exceeding thermal limits. PAL, (Power Average Limiter) limits the maximum average power consumption according to the power supply and mains-breaker capabilities.
3 INSTALLATION 3.1 Unpacking Carefully open the shipping carton and check for any noticeable damage. Every Lab.gruppen amplifier is tested and inspected before leaving the factory and should arrive in perfect condition. If any damage is discovered, please notify the shipping company immediately. Only the consignee may institute a claim with the carrier for damage incurred during shipping. Save the carton and packing materials for the carrier’s inspection.
INSTALLATION 3 3.3 Cooling The amplifier uses a forced-air cooling system with air flow from front to rear, maintaining a low operating temperature within defined limits. Front-to-rear airflow is preferred as cooler air is present at the front in nearly all applications. (This allows higher continuous power levels without encountering thermal problems.) Never attempt to reverse the airflow.

4 QUICK GUIDE OVERVIEW 4.2.1 Network and Configuration section Four-channel model shown. Two-channel versions have VPL and Bridge Mode switches for channels A and B only. All models have different VPL values. Functions are otherwise identical. Gain - Globally set for all channels, from +23 dB to +44 dB in 3 dB steps. Option active - Not currently implemented. Fan Masked - When on, engages the intelligent fan feature; fan speed is lowered when no signal is present.
QUICK GUIDE OVERVIEW 4 4.2.3 Input and Output connectors All FP+ Series amplifiers are equipped with balanced XLR-F input connectors. two-channel models also offer parallel (“loop-thru”) XLR-M output connectors for daisy-chaining multiple amplifiers from the same signal source. All FP+ Series amplifiers except the FP 9000, FP 13000 and FP 14000 offer a choice of either binding post (BP) or Neutrik© NL4FC Speakon output connectors (SP).
4 QUICK GUIDE OVERVIEW The NomadLink connections use standard “straight” Cat-5/RJ45 equipped cables. For a safer mechanical connection it is possible to use Neutrik EtherCon “XLR-type” housings on the cables. 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.
OPERATION AND PERFORMANCE 5 5.1 Introduction The following sections provide comprehensive information on amplifier connection, setup, operation, and performance. The detailed information included here is essential to realizing the full functionality of the FP+ Series amplifiers. 5.
5 OPERATION AND PERFORMANCE 5.3.2 Headroom, sensitivity and VPL / Gain settings The input amplifier and limiter system is designed to accommodate extremes of performance. Typically, exceeding maximum input by much as +10 dB will only result in a 1% increase in distortion. The following schematics illustrate how the adjustable VPL and Gain circuitry affect input sensitivity and output power. The tables to the left of the illustration 7.3.
OPERATION AND PERFORMANCE 5 5.4 Audio Input and Output connections 5.4.1 Balanced Input connections When linking the same source signal to several input channels, be aware that there is a limit to the number of channels an output source can “drive”. A typical output source (e.g. a DSP crossover unit) can drive up to four amplifier channels before external line-drivers might be required to buffer the signal. 5.4.2 Unbalanced Input connections Figure 5.4.1a: Audio inputs and loop-thru Figure 5.4.
5 OPERATION AND PERFORMANCE Two-channel amplifiers – Two-channel amplifiers are wired in the following manner. The right Speakon connector, Channel A+B, provides outputs for both Channel A and Channel B. This output is useful when wiring the amplifier for bridged mono operation. See section 7.4.6. The left Speakon connector provides an output for Channel B only. 5.4.
OPERATION AND PERFORMANCE 5 Never connect an output terminal to ground, or to any other input or output. Observe relative loudspeaker polarity: loudspeakers connected in reverse polarity will exhibit degraded performance, particularly in bass frequencies, and may be damaged as a consequence. Use a high-quality stranded loudspeaker cable, and keep cable runs as short as possible. 5.4.
5 OPERATION AND PERFORMANCE V peak V rms V peak V rms The values for VPL are displayed as maximum Voltage Peak. To translate Voltage Peak into Vrms, you must divide the Voltage Peak values by 1.41 (see table). The VPL allows you to set the correct maximum output peak power for optimum performance with the connected speakers. The correct setting depends on the system type and the specific load connected to the channel.
OPERATION AND PERFORMANCE 5 5.5 Protection, faults and warnings 5.5.1 Introduction The FP+ Series amplifiers incorporate a sophisticated and comprehensive set of protection features. Faults and warnings are indicated on the front panel and reported via the NomadLink network for indication on the DeviceControl GUI. 5.5.
5 OPERATION AND PERFORMANCE 5.5.5 High-impedance warning (open load) A high-impedance (open load) condition is indicated when an input signal above approximately -29 dB is detected and no functioning loudspeakers are connected to the amplifier. The fault in indicated by a orange Sig/Hi-imp LED.

5 OPERATION AND PERFORMANCE 5.6.4 Performance, Warning and Fault indicators Global Indicators: ▸▸ ▸▸ ▸▸ Figure 5.6.4a: Front panel global LED field ▸▸ ▸▸ ▸▸ Power on/off (green) indicates that mains power is switched on. NomadLink (blue) indicates that the network is connected. The NomadLink LED will light up even before the mains power is connected and switched on as it takes phantom power from the network cable.
OPERATION AND PERFORMANCE 5 It is very important that two IN or two OUT ports are NEVER connected to each other. This will cause the NomadLink communication and DeviceControl to exhibit erratic behavior and display inaccurate data. However, this situation will not damage the amplifier circuitry. Up to 60 amplifiers can be connected to one NLB 60E in a daisy-chain or closed loop. When the NLB 60E is powered up, the NomadLink network receives phantom power.
5 OPERATION AND PERFORMANCE ▸▸ ▸▸ 980 feet. Rule 2: In a non-closed-loop daisy-chained subnet the total maximum cable length is 400 meters / 1300 feet. Rule 3: In a closed-loop subnet the total maximum cable length is 700 meters / 2300 feet. 5.7.4 Ethernet network cable lengths The connection between the NLB 60E and your PC is a standard Ethernet network running the TCP/IP protocol. Cable distances between NLB 60E and your PC follow standard rules for Ethernet systems.
APPENDIX 6 6.1 Maintenance During normal operation your FP+ 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.
