Atoll MA100 Black

The MA100 mini power amplifier is suitable for most HIFI or audio-video applications. Very scalable, it can be used alone or in bi-amplification. It can be associated with an integrated amplifier or an ATOLL preamplifier. It is bridgeable in a monoblock via an internal switch. It is fitted as standard with a 12V Trigger input (direct ignition in conjunction with a preamplifier).

Presse Reviews

Your device can be used as a MONO power unit. Here are the steps to switch the amp to mono:

– Turn off your device and disconnect all cables:
(a) Flip the switch (3) to the MONO position (to the left).
(b) Connect the signal (from the preamp) to the white cinch AMPLI IN.
(c) Connect the AMPLI IN cinch (4) (red) to the AMPLI OUT cinch (5) (white) with a cable.

– Connect the cables to the speaker as shown below:
(d) Left output (red) to black speaker input.
(e) Right (red) output to red speaker input.

“Once again, the Atoll brand surprises with the relevance of the products. This time, it’s about small links, a particularity not felt when listening. Each element has been carefully thought out and optimized, we think in particular to the six inputs, including one USB 192 / 24 and two analog, with remote controllable volume, with the output impedance of only 1 ohm for headphones, without forgetting the MA100 power amplifier operating in class A up to 10 watts. Atoll left nothing to chance and found the best solutions in the technical, aesthetic, ergonomic, and, above all, musical aspects. Congratulations!”
