The ALSOZONE GaN Mono is a power amplifier monoblock mono Class D amplifier with GaN technology, designed for modern Hi-Fi systems and capable of delivering up to 300 W at 4 Ohm and 150 W at 8 Ohm. Its GaN Class D 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 Class D amplification with GaN transistors, designed to provide high efficiency and optimized thermal management. This design allows the monoblock amplifier to deliver up to 300 W at 4 Ohm or 150 W 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 12 V 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.
