The front panel Neutrik combination input can be used to connect line and instrument level signals as well as microphones. This makes it perfect for recording the output of a synthesizer or stage piano, while at the flick of a switch, you can cater to the output of an electric or acoustic guitar. Unique halo indicators let you know that you've got a good signal level for recording. Red means that your signal is clipping, and that you should reduce the gain. The halo will momentarily turn amber as the level returns to a healthy level, at which point it will turn green. A large monitor dial provides a tactile control for the volume of your speakers, while a high quality headphone amp provides a clean yet loud signal to headphones connected to the front panel socket. The direct monitor switch routes audio directly from the inputs to both the headphone and speaker outputs. This allows you to monitor the incoming signal with zero-latency.
