Overview

900W at 4Ω from each of four channels with bridgeable pairs: a single L4350 is good for powering a complete little bi-amped stereo system, a 3-way mono stack of decent size, a variety of floor monitors.

All at a quality level as can be expected from KernelS. Optimized for 4Ω loads, the L4350 is a fantastic value, practically as well as commercially.

In use worldwide by leading touring and event sound companies, KernelS amplifiers are preferred among the top ranking system designers, sound engineers, and contractors for providing reliable premier-grade power and headroom in the smallest possible package size.

Maximum efficiency warrants minimum current draw, heat dissipation, and power consumption, resulting in “green” products, saving the user a substantial amount of money over time.

Description

Power supply

  • Advanced switch-mode power supply technology for high performance and compact size
  • Fixed frequency switch mode output
  • Patented output filter with ripple cancellation network

 

Protections

Fully protected circuit design with:

  • AC protection: shut down power supply when AC mains voltage is outside the operating range
  • Clip limiter: prevents severely clipped waveforms from reaching loudspeakers, while still maintaining full peak power output
  • DC protection: protects against infrasonic signal at the outputs
  • VHF protections: protects the loudspeakers against non-audible, strong, non-musical high-frequency signals
  • Short circuit protection: protects the amplifier from short circuit or other stressful events for the output circuits with automatic protection reset
  • Long term limiter: protects the loudspeaker against steady long term RMS (non-audio) signals reducing maximum output
  • Thermal protection: output stages operating temperature up to 75 °C (167 °F)
  • Temperature controlled continuous variable speed fan, front to back airflow

 

General

  • Direct drive constant voltage, 70V Hi-Z distributed lines*
  • Compact size – all models only 1 RU for reduced rack cost and space
  • Lightweight – all models only 7.4 kg (16.3 pounds) for easier racking and shipping
  • Neutrik XLR balanced inputs and Speakon outputs connectors
  • Recessed stepped attenuators
  • Modular construction
