Product Overview & Specifications
The Lindemann Musicbook POWER II is a compact, high-efficiency Class D stereo power amplifier designed to deliver relaxed, highly detailed, and authoritative sound reproduction. Built upon N-CORE power buffering architecture paired with a newly redesigned analog voltage gain stage, the POWER II enhances acoustic resolution while maintaining exceptionally low distortion, a high damping factor, and minimal power consumption.
Engineered for maximum system flexibility, the POWER II can be configured in traditional stereo mode or switched to vertical bi-amping mode to drive high/midrange and bass sections independently. To solve room acoustics and speaker placement challenges, it features an integrated 10-step bass level control when operated in bi-amping mode, allowing fine-tuned low-frequency matching to your room.
KEY FEATURES & CIRCUITRY IMPROVEMENTS
- Independent J-FET Voltage Gain Stage: The primary voltage amplification circuit is separated from the N-CORE module, utilizing low-noise J-FETs powered by a clean energy supply with less than 1 µV noise floor.
- N-CORE Power Buffering Architecture: Uses N-CORE Class D technology purely as a current buffer, ensuring frequency-independent response and ultra-low distortion across all power levels.
- Vertical Bi-Amping Mode: Supports dedicated channel bi-amping (one amplifier per channel) to isolate bass and high/midrange drive signals for improved transparency.
- 10-Step Adjustable Bass Level Control: Offers a 10-step bass trim control in bi-amping mode to attenuate or boost low frequencies for difficult room placements.
- Enhanced Balanced Signal Auto-Detect: Revised, highly sensitive balanced signal detection circuit reliably triggers power-on/off functionality while rejecting ambient electrical interference.
- Acoustic Synergy with Musicbook SOURCE: Designed as the ideal companion power amplifier for the Lindemann Musicbook SOURCE streaming preamplifier.
