Lamm Industries M2.1 monoblock power amplifier Specifications

Sidebar 1: Specifications

Description: Monoblock power amplifier with a solid-state input stage, tube driver stage, and MOSFET output stage; switch-selectable output-stage biasing to maintain optimal performance into loads between 1 and 16 ohms; and remote-control power on/off. Tube complement: one 6922/6DJ8. Rated output power: 200W minimum into 8 ohms (23dBW), High impedance setting, continuous sinewave drive, 20Hz-20kHz, with <0.3% THD at rated line voltage, (36W in class-A); 200W into 4 ohms (20dBW), same conditions (36W in class-A); 400W into 2 ohms (20dBW), Low impedance setting, with <1% THD (18W in class-A); 600W into 1 ohm (18.75dBW, 9W in class-A). Frequency response: 4Hz-150kHz, +0, -3dB (1-200W into 8 ohms). Voltage gain: 31.8db ±0.2dB. Input sensitivity: 1.026V RMS ±2% for 200W into 8 ohms, High impedance setting; 725mV RMS ±2% for 200W into 4 ohms, Low impedance setting. Input impedance: 41k ohms shunted by 470pF. Output impedance: typically 0.2 ohm, 20Hz-20kHz. Slew rate: voltage out = 113.14V peak-peak of squarewave signal into 8 ohms, 40V/µs. IM distortion (60Hz:7kHz 4:1) SMPTE: <0.5%, 1-200W into 8 ohms at rated line voltage; <0.5%, 1-200W into 4 ohms at rated line voltage. Typical power consumption: 220W at idle, 350W at rated output at 8 (4) ohms.
Dimensions: 17" (432mm) W by 8.25" (210mm) H by 19.5" (495mm) D; add 2.8125" (72mm) D for front and rear handles. Weights: 65 lbs (30.16kg) net, 92 lbs (41.77kg) shipping.
