The ALSOZONE GaN Mono is a power amplifier monoblock mono amplifier with GaN technology, designed for modern Hi-Fi systems and capable of delivering up to 300W at 4 Ohm and 150W at 8 Ohm. Its GaN architecture combines high efficiency and optimized thermal management in a particularly compact format measuring only 118 × 90 × 35mm. It features RCA and XLR/TRS inputs, several adjustable gain modes as well as control functions including a 12V Trigger, Auto Standby mode and One-Key control. The amplifier accepts a 24 to 48V DC power supply.
The GaN Mono features amplification with GaN transistors, designed to provide high efficiency and optimized thermal management. Mono GaN is based, in particular, on the combination of a GaN FDA ACM8816 and a PCM1808 ADC. This design allows the monoblock amplifier to deliver up to 300W at 4 Ohm or 150W at 8 Ohm, to power a passive speaker with significant power despite its small footprint. Its 118 × 90 × 35 mm format allows it to be integrated into compact Hi-Fi systems or configurations requiring a low-volume power amplifier.

The ALSOZONE GaN Mono offers audio connectivity including RCA and XLR/TRS inputs, allowing it to be integrated into different Hi-Fi configurations. Several functions also make it easy to use on a daily basis, with adjustable gain modes, a 12V Trigger, Auto Standby mode and One-Key control. The amplifier operates with a 24 to 48V DC power supply; the configuration supplied with a 48V / 5A power supply allows the use of an external power supply suitable for the amplifier.
