Union Audio LISANN Headphone Amplifier
The Union Audio Lisann is a powerful and compact portable headphone amplifier. Perfectly suited for users who need to drive high-impedance headphones when streaming audio from a phone or laptop, or to record analogue signals back to a USB connected device.
Powered by high-capacity rechargeable batteries (Nickel Metal Hydride for safety), lisann includes a full, high-speed USB audio subsystem with optical digital, and balanced XLR analogue inputs. A powerful, semi-discrete class AB power amplifier drives the dual headphone outputs at levels of up to 750mW RMS into 33 Ohms, or up to +20dBu for high impedance headphones, thanks to 30 volt internal power rails.
With USB-C connectivity lisann can stream digital audio at speeds of up to 96kHz/24 Bit with clarity and dynamics from its AKM digital converters. In addition, lisann can record back to USB from any input source, either digital or analogue. With built-in battery management, and recharging from the supplied universal voltage adaptor, lisann will provide up to 12 hours of continuous usage.
