Lab Gruppen PLM 20K44 BP 20,000W 4-Channel Amplifier with Lake DSP and Network (Binding Post) - PLM20K44/BP

Product Overview

The Lab Gruppen PLM 20K44 BP is a 20,000W four-channel touring power amplifier with Lake Digital Signal Processing, Dante/AES67 digital audio networking, and binding post speaker outputs. It delivers 4 x 5,000W across impedance loads from 2 to 16 ohms and 70/100V, making it well-suited for both touring applications and permanent installations where binding post terminations are the preferred wiring method. The PLM 20K44 BP shares the full PLM+ architecture with the SP variant, differing only in output connector type.

Product Description

The Lab Gruppen PLM 20K44 BP is the binding post-equipped version of Lab Gruppen's flagship four-channel touring amplifier, offering the same 20,000W Class-TD output stage, Lake DSP engine, and dual-redundant Dante networking as the SP model. Binding post outputs are favored in permanent installation contexts where bare wire or spade-lug terminations are standard practice, and in some touring rigs where technicians prefer the flexibility of non-locking connections. Four pairs of binding post outputs are provided on the rear panel, one pair per channel. The amplifier accepts four balanced XLR analog inputs and two AES3 digital inputs, providing a full 4-in, 4-out signal architecture. Lake Controller 6.3 software enables complete remote configuration and monitoring of DSP parameters including FIR linear-phase crossovers, parametric EQ, delay, limiting, and 100 stored presets. Dante networking via dual etherCON ports with AES67 support allows the PLM 20K44 BP to integrate directly into any IP audio network. The Class-TD topology delivers high output efficiency and low thermal load, enabling the unit to maintain stable performance in demanding live sound environments. Selectable gain and per-channel Voltage Peak Limiter (VPL) give engineers precise control over output levels and loudspeaker protection. The 2 RU chassis includes rear rack support brackets and ships with a power cord for immediate racking.

Frequently Asked Questions

Q: Why choose the BP (binding post) version over the SP (speakON) version?

A: The binding post variant is preferred in permanent installation environments where cables are terminated with spade lugs, banana plugs, or bare wire ends. It is also used in some touring systems where the flexibility of non-locking connections suits the workflow. For touring rigs where quick cable locking is required, the PLM 20K44 SP with speakON connectors is the more common choice.

Q: Does the PLM 20K44 BP support 70V and 100V distributed audio?

A: Yes. The amplifier is rated for 70V and 100V high-impedance operation, allowing it to drive distributed ceiling or line-array speaker systems in addition to low-impedance touring loudspeakers.

Q: Is the PLM 20K44 BP compatible with Dante networks?

A: Yes. Dual redundant etherCON Dante ports with AES67 support are included. The amplifier can be configured and monitored via Dante Controller and Lake Controller software over a standard Ethernet network.

Q: What software is needed to configure the Lake DSP on this amplifier?

A: Lake Controller 6.3 software, available from Lab Gruppen, is used to access all DSP parameters including crossovers, EQ, limiting, delay, and preset management.

Q: How much rack space does the PLM 20K44 BP require?

A: The unit occupies 2 rack units (2 RU) in a standard 19-inch equipment rack. Rear rack support brackets are included.

Q: What mains power requirements should be planned for this amplifier?

A: Due to its 20,000W output capacity, the PLM 20K44 BP requires a dedicated high-current mains circuit. Reference the Lab Gruppen technical documentation for exact current draw specifications and comply with local electrical installation codes.

Q: What is included with the PLM 20K44 BP?

A: The amplifier ships with a power cord and rear rack support brackets. Lake Controller software is available as a free download from the Lab Gruppen support portal.
