About the INT-150

The Pass Labs INT-150 is a solid-state stereo integrated amplifier rated at 150 watts per channel into 8 ohms and 300 watts per channel into 4 ohms. Its design is based on the X150.5 power amplifier, combined with a buffered passive, relay-switched input selector and volume attenuator. The amplifier uses a low-feedback Class A/AB output stage, operating in Class A at lower power before transitioning to Class AB at higher output levels. It provides balanced and single-ended line-level inputs, a 63 dB volume-control range in 1 dB increments, and a damping factor of 150. Published specifications include a frequency response of 1.5 Hz to 60 kHz, 0.003% distortion at 5 watts into 8 ohms, and dimensions of approximately 19 inches wide by 7 inches high by 19 inches deep.
