Linn Majik 5100 Five-Channel Power Amplifier

The Majik 5100 is Linn's five-channel Exakt power amplifier — 100 W per channel into 8 Ω across five independent output stages, housed in a single compact chassis that simplifies the amplification requirements of some of the most demanding Linn Exakt active configurations available. Five channels in one box represents a genuinely practical solution to a genuinely complex problem: how to drive a multi-way active loudspeaker system — or a stereo active pair combined with a subwoofer — without the physical, financial, and logistical burden of five separate amplifier units. The Majik 5100 resolves that problem with characteristic Linn economy and without compromise to the quality of amplification each individual channel delivers.

In a well-planned Linn Exakt system, the 5100 is most naturally suited to two specific configurations: a two-way active stereo pair — four channels — combined with a single driven subwoofer channel, or a three-way active system on one speaker combined with two channels dedicated to a second speaker. In both cases, five independent amplifier channels are required, and the 5100 provides exactly that in a single chassis with a single mains connection. The alternative — five separate amplifiers — would require five power supplies, five sets of connections, and a rack space commitment that most listening rooms cannot comfortably accommodate.

Exakt Active Amplification at Majik Level

The Majik 5100 enters the signal chain at the amplification stage alone. All signal processing — digital crossover filtering, time alignment, and Space Optimisation room correction — is handled upstream in the Linn DSM, whether that is a Linn Majik DSM 5G, a Linn Selekt DSM Edition Hub, or a Linn Klimax DSM. The 5100 receives a processed digital signal via Linn Link and converts it to the controlled mechanical movement of a drive unit — five times over, simultaneously, with each channel independently driven from its own output stage.

There is no passive crossover anywhere in this signal chain. The frequency division that in a conventional loudspeaker system is handled by capacitors and inductors inside the cabinet — with the attendant phase errors, insertion losses, and timing anomalies those components inevitably introduce — is replaced by precise digital processing upstream. What each channel of the 5100 amplifies is exactly and only the frequency band its assigned drive unit is built to reproduce. The result is the low-level resolution, dynamic precision, and timing clarity that define the Exakt active approach and distinguish it from passive loudspeaker systems at any price point.

Each channel in the 5100 is independently driven, with its own output stage. The power supply is sized for the demands of five simultaneously active channels under sustained programme conditions — not merely for the average load that measurement conditions typically represent. There is no analogue input, no preamplifier stage, and no signal processing within the 5100 itself. Its purpose is amplification, and it performs that purpose across five channels without constraint.

Expanding and Combining

For system configurations where five channels are not quite sufficient, the 5100 combines naturally with other Majik amplifiers via Linn's Linn Link architecture. A Linn Majik 3100 mono block adds a single additional channel to reach six; a Linn Majik 2100 stereo amplifier adds two channels to reach seven. Multiple amplifiers are driven cleanly from a single DSM, and system configuration is managed via the Linn app. For extended bass management, the Linn Exaktbox Sub integrates seamlessly alongside the 5100 in configurations where a dedicated Exakt subwoofer channel is required.

Who Is It For?

The Majik 5100 is the natural choice for Linn Exakt active system builders who need five amplifier channels in the most compact, cost-effective, and straightforward single-chassis solution within the Majik range. It is equally at home as the sole amplifier in a two-way active stereo plus subwoofer configuration and as the foundation of a more complex multi-channel active build supplemented by additional Majik units. For those whose channel requirements sit between the four-channel Majik 4100 and the six-channel Majik 6100, the 5100 provides the precise count needed without redundancy and without compromise.

Buying from Martins Hi-Fi

Martins Hi-Fi has been in Norwich since 1968. Elizabeth Gould runs the business today, and we stock only brands we have heard properly and stand behind.

Planning the amplifier channel count for a multi-way Linn Exakt active system is exactly the kind of conversation we are well placed to have — we have configured these systems across a wide range of loudspeaker types and room situations, and we can help you arrive at the right combination from the outset rather than adding channels retrospectively.

When you get in touch, you'll be speaking with Dave, Chris and Tim — experienced specialists who can advise on this product and your whole system.
