Union Audio - lisann Headphone Amplifier

The lisann Headphone Amplifier is a compact tool designed to accompany users in a wide variety of environments. Its small size in no way detracts from its ability to deliver a powerful signal, thanks to a semi-discrete Class AB architecture that supplies two headphone outputs with up to 750 mW RMS at 33 ohms.

The internal 30 volts also meet the needs of high-impedance headphones, while preserving the dynamic range and precision of the signal. This versatility makes it an ideal companion for sound engineers, musicians, technicians and users looking for a reliable headphone monitor.

The device features a full USB audio section operating via USB-C, capable of playing streams of up to 96 kHz in 24-bit, ensuring transparent playback thanks to AKM digital converters.

The lisann can also record to a computer from any connected source, whether from the optical input or the analogue XLR input. This bi-directionality gives the device a hybrid role, as much a compact audio interface as a powerful headphone amplifier.

Battery power is one of the product's key features. The choice of NiMh batteries enhances safety and thermal stability, while internal management optimises autonomy for up to twelve continuous hours.

Recharging is via the universal external adapter supplied, which is compatible with a wide range of mains voltages. This solid battery life means you can use the camera on the move, on location, in the studio or on location without the immediate need for a power outlet.

Union Audio has taken great care in its design, combining high-end audio performance with robust construction. The XLR inputs accept levels of up to +20 dBu, guaranteeing wide compatibility. The extended frequency response up to 60 kHz and low distortion add a sense of clarity and dynamic reserve, reinforced by very low residual noise. The lisann remains a precise tool for critical monitoring, yet accessible for everyday use.
