Final power amplifier - AudioLai S2-7

Final power amplifier - AudioLai S2-7


AudioLai products are handcrafted and tested with rigor and accuracy... all this makes each product unique.

Delivery time: 2 or 3 weeks

The new AudioLai S2-7 power amplifier is a two-channel class D audio amplifier based on the most advanced technology (thanks to which the temperature, voltage and current of the amplifier is continuously monitored with activation of a alarm and multilayer protection if the operating conditions are close to the protection limit).
It combines an efficient LLC resonant converter (with enormous power capacity) with two class D amplifiers capable of delivering over 2x500 W of very high quality and definition audio. Its ability to handle low impedances means the amplifier is capable of delivering up to 1000W even into 2.7Ω loads.

Clear and crystalline medium highs and exciting lows, with an incredible punch, in fact the damping factor exceeds 500.

The frequency response is stunning, in fact the range includes frequencies from 1.5Hz to 70kHz, where most general amplifiers reach a maximum of 20kHz.

Power (4 ohms)

Distortion THD + N (1W/1kHz)

550 watts X 2


It can be connected directly to the digital source/DAC, or to a phono preamplifier.

Here are some of the main features:

  • Output Power: 2x550W (4Ω), 2x370W (8Ω)
  • Distortion THD + N (1W/1kHz) = 0.006 %
  • Minimum load impedance = 2.7 Ω
  • Dynamic range = 117db
  • Frequency response: 1.5hz-70Khz
  • Voltage Gain: 27.4db
  • Input impedance: 36Kohm
  • Output idle noise (A) = 70mV
  • Maximum output current: 30A
  • Dimensions and weight: L330mm X D280mm X H100mm - 7Kg
  • Inputs: 2 unbalanced RCA inputs
  • Mains: Universal mains, auto select (100-240 V, 50-60 Hz)

To make the most of the potential of the AudioLai S2-7 amplifier, we recommend using the AudioLai TI isolation transformer which reduces disturbances in the domestic electrical network to a minimum, especially if highly sensitive speakers such as the AudioLai Lura Diecici are driven.
