Outline L3000 – Introducing The World’s Toughest Compact Power Amplifier!

L3000 is a ready-to-use and ultra-light 3000-Watt Power Amplifier. It’s compact, practical, smart, and freestanding.

Its four channels of amplification combined with the internal DSP provide the perfect solution for many applications. The flexible two-, three- or four-channels format is ideal for installations but also for portable systems.

L3000 is transportable and installable everywhere, and features the same attractive and durable finish as Outline’s touring loudspeakers.

This amplifier offers small dimensions, light weight (just 3.4 kg / 7.5 lb) and the traditionally amazing sound quality and reliability of all Outline products. The L3000 can deliver up to 750 W per channel at 4 Ω or 1500 W in bridge mode at 8 Ω. Outline amplifiers deliver crystal-clear highs and a tight, well-defined low end.

Proven design features ensure extremely high performance in terms of super-low total harmonic distortion, optimal frequency response and damping factor across a vast number of application scenarios. The PWM output stage allows to transform all the energy drawn from the mains into usable power and offers maximum performance, high predictability and immunity from intermodulation artifacts.

All output connections are made via speakON connectors. Both bridge and single channel output connection modes are available. The channels A, B, C and D can be set in single-ended mode, E and F in bridge mode. The amplifier offers 4 presets, which change the routing of the signal.

L3000 comprises a range of functions that can be setup manually using ArmoníaPlus, amplifier management software, which offers control of parameters such as levelsdelaypolarityEQ and limiter settings.

L3000 amplifier can be mounted in two rack units (19” x 3.5”, 483 mm x 88 mm) with the appropriate hardware. Using the accessory shown in the figure it is possible to mount two L3000s side by side or just one amplifier, if preferred.
