LAB GRUPPEN C 5:4X เพาเวอร์แอมป์ High continuous output power of 125 W per channel  at 70 V, 4 ohms, 8 ohms, and 16 ohms เครื่องขยายเสียง 

 

• Four channels in 2U - High channel density reduces space 

requirements and installation time

• High continuous output power of 125 W per channel 

at 70 V, 4 ohms, 8 ohms, and 16 ohms*

• All channels individually selectable for lo-Z or hi-Z 

Loudspeakers (2 ohm – 16 ohm) and distributed systems can be 

connected to the same unit

• Bridged operation – Channel pairs bridgeable for increased 

output or for driving 100 V systems 

• Patented output stage based on Class D topology

• High efficiency for lower thermal stress

• General Purpose Input/Output (GPIO) – Compatible with 

third-party control systems

• NomadLink® network ready

• Universal Power Factor Corrected PSU with IEC inlet 

• Efficient cooling – Dual variable speed, intelligent fans and 

parallel airflow over output devices provide uniform cooling

• Comprehensive circuit protection and fault indication

• Phoenix-style input connectors and barrier strip output 

connectors

 

An Installation Amplifier without Compromise

Lab.gruppen amplifiers have earned an enviable worldwide reputation for sonic excellence and rock-solid durability in touring sound applications. These same qualities are now available for a broad range 

of installed sound applications in the C 5:4X amplifier. By offering an 

unmatched combination of channel density, operating efficiency and 

configuration flexibility, the C 5:4X presents convincing performance 

and cost-saving advantages. Applications include primary systems 

for theme parks, shopping malls, airports, hotels and restaurants as 

well as auxiliary systems for performance venues, houses of worship 

and numerous other installed sound applications.

To achieve higher channel density without compromising performance, Lab.gruppen engineers developed a new output stage 

design. Based on a patented Class D circuit topology, these output 

stages produce sustained high power levels with very low distortion 

while maintaining efficiency levels of near 90%. A new universal 

switching power supply employs Power Factor Correction (PFC) 

to stabilize current draw, and it accepts any mains voltage from 

100 – 240 V (+/- 10%) @ 50 Hz or 60 Hz through the appropriate 

IEC cord.

The C 5:4X includes include unique features which enable each unit 

– or even each channel – to be configured for a specific application 

or load condition. Input gain is selectable in two-channel groups, and 

a 35 Hz high pass filter may be inserted. All channels are bridgeable 

in pairs, and Lab.gruppen’s exclusive Voltage Peak Limiter (VPL) feature allows each channel to be individually optimized for the reactive 

characteristics of the connected load. 

For comprehensive remote monitoring and control, the C 5:4X 

includes NomadLink® network ports for connecting to an optional 

NLB 60E NomadLink® Bridge & Network Controller and an Ethernetlinked PC. With NomadLink®, key amplifier parameters are displayed 

via DeviceControl software, and remote control of channel mute 

and power on/off is under network control. Alternatively, the GPIO 

facilities allow access to key amplifier functions via third-party 

remote control systems.

To ensure a long and trouble-free service life, the C 5:4X incorporates 

extensive features to safeguard internal circuits and connected loads. 

Protection and warning circuits prevent damage or service interruptions due to excessive current, DC at output, over-temperature, 

non-musical VHF (very high frequencies), and open load conditions. 

In addition, soft-start and PSU current limiting protect the mains 

supply from interruptions due to tripped circuit breakers or blown 

mains fuses.
