Featuring technology deprived from our legendary SPM range, the Mezzo 140 is an incredibly compact amplifier that punches well above its weight, to powerful levels, with stunning clarity.
The Mezzo 140 is a high-quality compact power amplifier designed to partner with a number of products from our Choral range. It was conceived to offer generous levels of power within a stylish and attractive chassis. Developed from the original Mezzo designs, the Mezzo 140 features four of our ultra-high-frequency power supplies with unique drive circuitry, plus a massive additional bank of energy-storage capacitors.
Its configuration offers performance in line with our full-sized products including increased voltage swing, a greater dynamic range and the ability to cope with demanding loudspeaker loads. The Mezzo 140 is rated at 140 watts into 8 ohms, but for even greater headroom, the Mezzo 140 can be run in bridged mono mode with a second Mezzo 140, providing 280 watts into 8 ohms. An automatic bridging mode feature allows bridged mono operation without additional cables.
The amplifier is supplied with high-quality gold-plated WBT speaker binding posts and further features include two phase-shift toggle switches on the rear panel, one for each output, to account for various speaker configurations.
Precision machined from a solid block of aircraft grade aluminium, a work of art on its own, the Ensemble Stand is irrefutably the most satisfying way to display your Choral system components or stack.
