Know before you buy
Yes, the MA100 is designed to support bi-amplification. Its compact footprint makes it an excellent choice for users looking to add dedicated power to their high-frequency or low-frequency drivers in a bi-amped setup.
The amplifier features a bridgeable mono mode, which can be activated via a switch on the rear panel. This configuration increases the power output to 150 Watts into 8 Ohms, providing more headroom for demanding speakers.
The MA100 is highly versatile and compatible with most standard preamplifiers or integrated amplifiers that feature a pre-out connection. It uses standard RCA inputs, ensuring easy integration into both HIFI and home theater systems.
The 12V trigger input allows the MA100 to automatically power on or off in sync with your preamplifier or processor. This eliminates the need to manually toggle the power switch every time you start your listening session.
With 60 Watts per channel into 8 Ohms, the MA100 is well-suited for most bookshelf and medium-sized floor-standing speakers. If you have particularly power-hungry or low-sensitivity speakers, you may want to consider using two units in bridged mono mode for increased power.
While the MA100 uses a high-quality Class AB design, it is relatively efficient for its size. However, like any amplifier, it requires proper ventilation; ensure you leave a few inches of clearance around the top and sides to allow for natural heat dissipation.
