TWO NOTES AUDIO ENGINEERING OPUS AMP SIMULATOR AND IR LOADER | Steve Sattler
OPUS from Two notes Audio Engineering is an all-in-one amp simulator , IR loader , and DI . About the size and shape of a typical stomp box , OPUS is the evolution of the Two notes Audio Engineering C . A . B . M +. While visually similar to the C . A . B . M + and sharing some similar design specifications , OPUS adds a number of important new features which greatly expands its overall capabilities as an Amp simulator . OPUS , like the C . A . B . M + is designed to be used in many ways ; on your pedalboard , plugged into your guitar amps effect loop , as a front end to a reactive load box , as a DI for connecting to your Church ’ s front of house or running straight into a preamp of your DAW or recording console .

While there is no exact reference to the amp counterparts of each available preamp model , all the basics i . e ., Fender , Vox and Marshall emulations are covered . There are also preamps dedicated to bass guitar . There are no preamps for acoustic guitar , but a suite of Acoustic Guitar Impulse Responses is included . OPUS also carries over the C . A . B . M + user configurable power amp stage which can be used fully separated from the preamp simulations . This is a really useful feature which adds significantly to OPUS overall flexibility and capabilities as an Amp simulator .
OPUS has one quarter inch input that can be set as a guitar or bass input , as a line-level input or set to be passed through to the input of your Guitar amplifier . There is a balanced XLR output to be used to connect the unit to a speaker or a load box as well as a TRS quarter inch balanced output for passing the input through to a destination input source , an audio interface for example . There is also a MIDI input accessible via a mini jack that allows OPUS to be easily integrated into a pedalboard setup .
OPUS runs at 24 bits and 96 kHz with 32 bits internal processing . Power to OPUS needs to be at 12 volts and 200 mA , most standard 9 volt power supplies will work to power the unit .
