Compact Hi-Fi Amplifier in a Durable Aluminum Enclosure!

The MAMP-250BT from McGrey shines wherever space is limited or flexibility is required. With 2x 50 watts in a sturdy aluminum enclosure it performs admirably—whether in the home living area or at the workplace.

Powerhouse

Connected to speakers with 4 O impedance, the small amp delivers 100 watts of output, providing plenty of volume to cover home living areas or hospitality spaces. With 8 O speakers it produces 30 watts per channel. The high efficiency pays off in both lower energy consumption and reduced heat generation.

Bluetooth Receiver

Inside the compact chassis is a Bluetooth 5.0 receiver that enables wireless streaming of music from up to 10 meters away. Inserting a 3.5 mm jack into the Aux input automatically disables the receiver.

Compact Enclosure

The sturdy, compact aluminum enclosure offers several advantages. With its sleek design the amplifier integrates perfectly into any existing Hi-Fi setup and meets aesthetic demands on its own. Thanks to its compact dimensions, the MAMP-250BT fits even the smallest niche and can be completely "hidden" if required. The energy-efficient circuitry produces very little waste heat, so you don't need to worry about heat buildup.

USB Input

The micro USB port allows the MAMP-250BT to be used as an external soundcard, enabling passive desktop speakers to be used. Simply connect directly to a computer's USB output and you're good to go!

Applications

The MAMP-250BT proves itself as a classic Hi-Fi amplifier in the living room as well as in hobby rooms and small workshops. Multiple units together make it possible to power different rooms at different volume levels.

Other Connections

For outputs, the terminal provides gold-plated screw terminals for bare wire or banana plugs.

Super mini amplifier for many applications in smaller rooms.
Ideal for party rooms or similar.
Whether from the TV, the old stereo system or via cell phone (Bluetooth). Even gets something out of old speakers that are too good to throw away.
very good

Order went smoothly, the amplifier does what it is supposed to do and sounds good doing it - all great. Only the documentation for the amplifier could be a bit better: the manual is pretty useless.
