Mac Audio Titanium Pro 4.0

The 4-channel amplifier Titanium Pro 4.0 delivers a powerful maximum output of 350 watts per channel at a stable 2 ohms. A full-featured crossover provides generous adjustment options, including a variable high-pass filter from 10 to 200 Hz (12 dB per octave), a variable low-pass filter from 30 to 150 Hz (12 dB per octave), and a variable bass boost between 0 and 12 dB at 45 Hz. Additional features include low-level outputs with a summed signal from channels 1 to 4 for connecting a subwoofer amplifier, a DUPE circuit for forwarding the audio signal from channels 1/2 to channels 3/4 with identical filter settings, and a channel mode selector switch. Bridged or tri-mode operation is also possible. The design aluminum heat sink, featuring an engraved model name and a sleek hairline finish, not only offers a stylish look but also optimal temperature management.
