Compact Hi-Fi Amplifier in a Robust Aluminum Housing!

The McGrey MAMP-250BT is ideal wherever space-saving or flexibility is needed. With 2x 50 watts output in a sturdy aluminum housing, it looks great everywhere – whether in the home living area or at the workplace.

Powerhouse

When connected to speakers with 4 Ohm impedance, this small amp delivers 100 watts of power, providing enough volume to fill home living spaces or hospitality areas. With 8 Ohm speakers, it produces 30 watts per channel. The high efficiency benefits both energy consumption and heat generation.

Bluetooth Receiver

The compact housing contains a Bluetooth 5.0 receiver that allows wireless music streaming from up to 10 meters away. Plugging a jack into the aux input automatically disables the receiver.

Compact Housing

The sturdy and compact aluminum housing offers several advantages. Its sleek design integrates perfectly into any existing hi-fi setup and meets all visual demands. Thanks to its compact size, the MAMP-250BT fits even the smallest niches and can be completely "hidden" if needed. The energy-efficient circuitry produces very little heat, so there’s no need to worry about overheating.

USB Input

The micro USB port allows the MAMP-250BT to be used as an external sound card, enabling passive speakers to be used at the desk. Simply connect directly to a computer’s USB output and you’re ready to go!

Applications

The MAMP-250BT excels as a classic hi-fi amplifier both in the home living room and in hobby rooms or small workshops. Multiple units can be combined to provide different rooms with varying volume levels.

Other Connections

The output terminal features gold-plated screw clamps for bare wire or banana plugs.

The space-saving solution for many applications!
