The X150.5 stereo amplifier embodies the design technology and refinements of the larger "X" series amplifiers including the patented Supersymmetry™ circuit.

The X150.5 is rated at 150 watts per channel in 8 ohms and 300 watts into 4 ohms.

The appearance of the X150.5 is similar to the larger amplifiers in the series. The face plate is machined from thick aluminum stock and then anodized instrument gray. Like our larger amplifiers it has a front panel meter that indicates output device bias current.

The main power switch is located on the rear of the amplifier and a convenient standby switch is located on the front panel. The input, output, and AC connector are located on the rear of the amplifier. Single-ended inputs are via RCA connectors and balanced inputs are via XLR connectors. Heavy duty five-way binding posts are provided for the speaker outputs.
