ATC SIA2-150 MK2 is a high performance 150 Watt per channel Stereo Integrated Amplifier perfectly suited to driving ATC speakers or any other high-end speakers of your choice.
ATC has an enviable heritage and a sterling reputation in designing and manufacturing no-compromise studio electronics including the power amplifiers included in all their Active monitors. Built on this experience, the SIA2-150 MK2 was designed as a powerhouse amplifier packing tremendous power with stunning detail and delicacy.
The exemplary balance of features and power output in this hi-fi amplifier meets a broad and stringent set of requirements that is sure to impress both discerning audiophiles and music enthusiasts. It has a sound signature that is unwavering in midrange candour and fluidity. The extremely low distortion delivers solidity and precision of the stereo sound stage recreating the full presence of the recording.
Subtle & Tender
An exceptionally subtle and temperate performer, SIA2-150 carries across the poised serenity of recorded dynamics with sensitivity and inner detail by reducing distortion and non-linearities to levels well below audibility. The simple and direct signal path within the pre-amp stages preserves subtle low-level data and ensures that the whole pre/power amplifier combination remains neutral and free from colouration.
FET Power Amplifier
The output power of 150W is sufficient to reproduce well-recorded material from Rock, Pop, Classical or Jazz genres at realistic levels. As designers of the world’s most sophisticated drive units, ATC has a unique insight of what’s needed to accurately drive a genuine loudspeaker load. The grounded source FET power amplifier, which is also used in all ATC Active monitors, provides high current and damping to fully control any passive monitor.
Class AB Solid State
SIA2-150 is a Class AB solid-state amplifier offering a significant amount of warm Class A bias. It uses the same gain-reduction and protection circuits that ATC packs into its bi/tri-amp active speakers to prevent clipping at high output levels which can damage loudspeaker drivers.
Proudly retro-looking and minimalist, the titanium-anodized aluminium front panel of the amp has only basic inputs, volume wheels along with a standby button. An easy-to-use remote control is included as standard meeting contemporary expectations.
