These include insert effects such as equalization/dynamics processing and send-return effects such as reverb and chorus/delay. Over 140 studio-quality DSP effects are provided.
There are also dual balanced ¼' TRS output jacks and a headphone output with a dedicated volume control. Phantom power of +24 or +48 volts can be applied to both inputs, allowing the use of external condenser microphones.
Both can handle mic- and line-level signals, and Input 1 can also handle instrument-level signals from passive or active electric guitars and basses. The R8 provides dual inputs on combo connectors which can accept either XLR or ¼' balanced or unbalanced cables.
