MPS Limited 1100W Monoblock Class D Subwoofer Amplifier

The MPS Limited amplifiers were developed for the true audiophile who demands both fidelity and power, and were created to commemorate Morel's 45th anniversary.

MOR MPS 1.1100 LTD

HiFi Purity

The MPS Limited range is immediately set apart by its all-gold-plated connections, including special chassis-mounted RCA connections and robust power and speaker wire terminals. Inside, the signal path has been meticulously designed using Burr-Brown OPA2134 op-amps, which give the amplifiers their natural and detailed sonic character. Low-tolerance surface-mount components and WIMA metallised film capacitors preserve signal integrity throughout. Ultra-low ESR, high-voltage Rubicon capacitors in the power supply and output sections deliver the dynamics and resolution expected of truly high-end performance.

Optimised for Thermal and Power Efficiency

The compact MPS Limited chassis was developed using advanced computational analysis, allowing both models to share the same chassis dimensions whilst managing the different thermal demands of their respective amplifier topologies. This ensures power output is maximised and remains stable at any volume level.

Selectable Voltage Rail Power Supply

The MPS 2.150 Limited features a unique selectable voltage rail design. Because Class AB amplifiers run hotter than Class D equivalents, this allows users to match power delivery to the impedance of the connected speaker, keeping the amplifier within its optimal thermal range. In high-power mode the MPS 2.150 Limited produces 150W x 2 into a 4-ohm load; switching to high-current mode optimises it for 150W x 2 into 2 ohms. This makes for an exceptionally stable platform and an effective way to exploit the amplifier's full power potential.

Stackable HiFi Car Amplifiers

Keeping the amplifier footprint small was a priority, but active configurations and DSP-based systems often require multiple channels of amplification. To address this, MPS Limited models feature unique cast aluminium end caps with removable plates, enabling various mounting options including vertical stacking. The optional MPS-STKP stacking plates allow installers to minimise floor space when using multiple amplifiers, and both the chassis and stacking plates are designed to maintain maximum thermal efficiency throughout.

Installation Forward

As with the current MPS amplifier range, installation and ease of use were key priorities. Single-sided circuit layouts place all connections on one side of the amplifier for a clean, straightforward install. Preamp tuning and settings are located discreetly beneath a removable panel at the top of the unit, alongside auto turn-on selection via remote +12V, signal sensing, or DC turn-off sensing.

Simple Elegance

Designed with simple elegance and considered detail, the MPS Limited models mark the start of a new chapter in compact HiFi amplification. They deliver the power and fidelity to complement any Morel system with genuine audiophile performance.
