Features
The Sonnet 120 acoustic amplifier brings a simple control set with intuitive design
to give you the pinnacle of acoustic tone.
The preamp channels of the Sonnet 120 have been designed with your performance
in mind. Both channels feature a combination XLR / jack INPUT for microphone or
instrument use, PHANTOM +48V power, a PAD switch, full EQ and a dedicated
ANTI-FEEDBACK control to help suppress unwanted feedback. A PHASE switch is
also included which can help feedback control or alternatively be used for correcting
phase issues when using two signals from the same instrument.
The Sonnet 120 also features high quality digital REVERB on both channels, with
four reverb types and the ability to adjust the reverb tail via the REVERB TIME control
on the top panel.
H.P. FILTER (High Pass filter) and BRILLIANCE controls provide further control over
your tone, allowing you to sculpt how your acoustic guitar is amplified.
A USB connector allows for sending a processed output into a computer for
recording purposes and balanced XLR D.I. OUTPUTS also allow the signal to be
connected to external devices for practicing, recording or live use.
The MP3 / LINE IN jack allows you to connect your Sonnet 120 to a music device or
drum machine to play along to, or use the Bluetooth capability of the amp to make
connecting to an external device even easier.
