5,000 Watt Amplifier with 4 Flexible Output Channels, Lake Digital Signal Processing and Digital Audio Networking for Touring Applications
The PLM 5K44 power amplifier packs 5,000 Watts: 4 x 900 Watts @ 2 Ohms; 4 x 1,250 Watts @ 2.67 Ohms; 4 x 1,250 Watts @ 4 Ohms;
4 x 1,250 Watts @ 8 Ohms, 4 x 700 Watts @ 16 Ohms, into a lightweight (25.1 lbs / 11.4 kg), 2U rack-mountable chassis. Plus, the built-in LAKE DSP ensures the ultimate signal integrity across an extremely broad dynamic range (> 112 dB). PLM 5K44’s proven and reliable IDEEA output stage accompanied with an advanced power supply that provides best-in-class Power Factor Correction (PFC) with Current Draw Modeling, reducing running costs and minimising environmental impact.
Rational Power Management (RPM)
On top of the outstanding performance you have come to expect from a PLM+, the PLM 5K44 also contains Rational Power Management (RPM), a proprietary LAB GRUPPEN technology that gives system designers and techs unprecedented freedom to allocate the output power available among the four channels for optimal performance with specific load conditions. RPM provides the unique opportunity to scale a channel up from its average quarter, to a maximum of 2,000 Watts to match the requirements of a power-hungry low frequency driver – but still have available power for the other channels. This helps to minimize equipment costs, reduce rack space and improve long-term energy efficiency – all without compromising performance.
Dante Digital Audio Network
PLM 5K44 is equipped with Dante, a self-configuring digital audio networking solution from Audinate, based on the newest developments in networking technology. Dante provides reliable, sample-accurate audio distribution over Ethernet with extremely low latency. Dante incorporates Zen, which opens communication between the PLM 5K44 and all other Dante-enabled devices on the network – and automatically configures them. PLM 5K44 seamlessly incorporates any of the eight available Dante input channels into the LAKE Modules, while simultaneously transmitting eight unprocessed Dante channels onto the network. PLM 5K44 supports Dual Redundant Dante with dual networks for insurance against cable or switch faults, as well as multiple inputs for sender redundancy through the automatic failover routers.
Legendary LAKE DSP
The onboard, full-featured LAKE processor provides virtually-effortless group control via its Raised Cosine MESA EQ asymmetric filters – so it can match the response of virtually any loudspeaker system. The included LAKE Controller software provides a unified interface for control and comprehensive monitoring of both amplifier status and connected loudspeaker loads. Optimized for a wireless tablet PC, LAKE Controller is easy and intuitive to operate, with the “feel” of real-time analog faders and controls. LAKE processing also offers classical crossovers (selectable up to 48 dB per octave), FIR (finite impulse response), as well as linear-phase crossovers that are capable of slopes exceeding 180 dB per octave for even greater control.
The PLM 5K44 has a universal regulated Switch Mode Power Supply (R.SMPS) that can connect to any mains suply in the world, and reliably deliver full power despite fluctuations in the mains supply. The built-in Breaker Emulation Limiter (BEL) algorithm prevents the breaker from tripping by modelling the breaker’s temperature using configurable breaker profiles, nominal current, and controlling the mains draw to maintain safe limits. While the Under-Voltage Limiting (UVL) allows continued operation despite severe voltage drops. The design also incorporates best-in-class Power Factor Correction (PFC) to reduce peak current draw from the mains. Additionally, internal energy storage and design-inherent rail regulation maintains stable rail voltages during extended bursts, so extreme low-frequency beats cannot adversely affect mid- and high-frequency headroom.
