DS450M
Monaural Power Amplifier
The DS450M mono amplifier adds a new level of performance and flexibility to our Definition Series of amplifiers.
Providing abundant power, dynamics and control in a compact chassis, the DS450M rounds out the DS amplifier lineup.

There are several reasons to choose the DS450M over its stereo counterpart. The most important is performance-based:
a monaural amp simply produces a bigger, more spacious soundstage. Also, we were able to fit a much larger power
a monaural amp simply produces a bigger, more spacious soundstage. Also, we were able to fit a much larger power
supply in the chassis. Then there is the issue of size: the DS450M is smaller and easier to situate than the hefty DS450
stereo amplifier. In addition to its reduced height, the DS450M mono is 4.15 inches (10.5 cm) shallower, allowing it to fit
in a much tighter cabinet space. And, lastly, the DS450M is also perfect for multi-channel home theater systems when

you only need one more powerful and dynamic amplifier channel. Rated power is 450 watts into 8 ohms.

The DS450M has the same chassis size as the DSi200 and DS225, and continues the same design philosophy of other
Definition Series amplifiers. Our proprietary “hybrid Class D” all-discrete
analog switching-mosfet output technology is
combined with an enormous linear analog power supply, yielding tremendous speed and power delivery in a compact,
cool-running chassis. This remains a distinctive Audio Research design from the ground up, forsaking the use of
prepackaged “OEM” solutions common to other switching amplifiers. Each DS450M idles at only 55 watts. One major
enhancement that allows a pair of DS450M’s to offer even higher performance than a DS450: the energy storage of a pair

enhancement that allows a pair of DS450M’s to offer even higher performance than a DS450: the energy storage of a pair
of DS450M monoblocks is 1,368 joules, an increase of 62% over the DS450. The immense power supply will jump-start

Like all Audio Research products, the DS450M is made by hand in our Plymouth, Minnesota facility. Connections are
hand-soldered, not press-fit nor wave-soldered. All metalwork, boards, transformers and major parts are American-made
and sourced locally. We take a great deal of pride in our workmanship, and so will you.
