{"product_id":"atollin100sigsi","title":"Atoll IN100 Signature Integrated Amplifier, Silver","description":"\u003cp\u003eThe Atoll IN100 Signature is an analogue stereo integrated amplifier with dual-mono power supply, delivering 2×100 watts at 8 ohms and expandable with phono and DAC cards.\u003c\/p\u003e\n\u003cp\u003eEleven kilograms, two toroidal transformers, no display – the IN100 Signature is the kind of amplifier you buy and then almost forget about, because it simply works every day.\u003c\/p\u003e\n\u003ch2\u003eWhy the IN100 Signature?\u003c\/h2\u003e\n\u003cp\u003eBecause it brings Atoll's core principles to the entry class: two 340 VA toroidal transformers (680 VA combined), 31,474 µF filter capacitance, a Class A\/B design with a discrete preamp stage. Five line inputs and a home-cinema bypass cover everyday use, two pre-outs allow for a subwoofer or bi-amping later. And the AUX input turns into a phono input with a plug-in card.\u003c\/p\u003e\n\u003ch2\u003eWhat you hear\u003c\/h2\u003e\n\u003cp\u003ePower with manners. The bass stays controlled, the mids are clear, and the treble stays civilised even at higher levels. The 100 watts aren't a brochure number – at 4 ohms they climb to 140 watts instead of faltering. A headphone output with 6.35 mm jack sits on the front, a 12-volt trigger for automation at the back.\u003c\/p\u003e\n\u003ch3\u003eWho is the IN100 Signature for?\u003c\/h3\u003e\n\u003cp\u003eFor a first proper system, or as a solid core in a normal living room – and for anyone who wants to start small and expand step by step. \u003cstrong\u003ePlain talk:\u003c\/strong\u003e the remote control is an accessory and not included – that regularly surprises people, so we'd rather say it upfront. Streaming and digital inputs are missing out of the box, as is an XLR input. For very large rooms or hard-to-drive speakers, the IN200 Evolution is the more honest choice.\u003c\/p\u003e\n\u003ch2\u003eOur verdict\u003c\/h2\u003e\n\u003cp\u003eWhen we're asked to recommend an amplifier that lasts ten years and doesn't feel undersized after five, we often land here. Christian Rechenbach wrote about it in hifitest.de: «Der IN-100 ist ein Vollverstärker klassischer Schule, der jeder Anlage ein saubere Fundament liefert.» Which speakers do you have – or would you like?

You can order it separately – it then also controls the other Atoll devices in your chain.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow much power does the Atoll IN100 Signature have?\u003c\/strong\u003e\u003cbr\u003e2×100 watts at 8 ohms and 2×140 watts at 4 ohms, supplied by two 340 VA toroidal transformers and 31,474 µF filter capacitance. That's plenty for living rooms up to around 30 square metres and speakers of normal sensitivity.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan I connect a turntable to the IN100 Signature?\u003c\/strong\u003e\u003cbr\u003eYes, with a phono card. The P50 turns the AUX input into an MM input, the P100 can additionally handle MC with switchable termination impedance. Without a card, you connect an external phono preamp to one of the five line inputs.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDoes the Atoll IN100 Signature have digital inputs?\u003c\/strong\u003e\u003cbr\u003eNot from the factory. The DA100 and DA200 cards retrofit them: the DA100 with two coaxial and two optical inputs, the DA200 additionally with USB-B and Bluetooth. That turns the analogue amplifier into a hub for TV and computer.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhy buy the Atoll IN100 Signature from HD Zürisee?\u003c\/strong\u003e\u003cbr\u003eBecause with the right speakers, this amplifier plays surprisingly far above its price.
