Power amplifiers stereo — JAVA Hi-Fi DOUBLE SHOT GAN FET

In the Double Shot GaN FET stereo power amp from JAVA Hi-Fi, gallium nitride output transistors produce high power from a compact chassis. JAVA Hi-Fi bases its amplifier catalogue on GaN FET technology, and this model belongs to its GaN FET power amplifier range.

Key specs that matter

Rated output is 400 W into 8 ohms, doubling to 800 W into 4 ohms. The chassis measures 440 x 415 x 130 mm and weighs 9.2 kg, which is light for an amplifier of this rating.

Engineering and use context

GaN FET output devices are a relatively recent development in power amplification. Compared with conventional bipolar or MOSFET output stages, they allow high output with considerably less heat and bulk, which is how the Double Shot reaches its rating in a slim, light case.

Pairing

The available power suits demanding or low-sensitivity loudspeakers without the need for a large, heavy amplifier, a practical point in a system where rack space or weight is limited.

Alternatives

For less power, JAVA Hi-Fi offers the Single Shot GaN FET in the same stereo power amplifier range.
