The Lombardi’s LAQUAD1400 is a 4 channels fully analog audio stereo amplifiers, class AB. The amplifier was designed to be highly efficient and to maintain accurate audio performances in the whole bandwidth even under stress condition.
In the Lombardi LAQUAD1400 there are 4 audio Amplifiers, 4 Crossover and 4 safeguard independent Optical Limiters for each channel. The high quality of its components, the switching transformer and the handmade production guarantee the highest standards of Lombardi’s made in Italy products.
The audio amplifier LAQUAD1400 was tested to the limit (impedance less than 2 Ω) before it was placed on the market.

| Audio Crossover |
– Electronic audio crossover that can be inserted individually in every channel (4 independent crossovers)
– 12 dB/oct. 3 cut-off frequencies selectable from the front panel
– Cut-off frequencies Low Pass: 113-145-3200 Hz (factory settings)
– Cut-off frequencies High Pass: 113-145-3200 Hz (factory settings)
– When the High Pass and the Low Pass are selected at the same time the result is a Band Pass with the chosen cut-off frequencies
– When no cut-off frequency is chosen the amplifier is linear |
