Controls
- Input Channel 1 – This input accepts both XLR and 1/4″ (6.35mm) style plugs. Connect a microphone, instrument, or line-level signal source here. The 1/4″ (6.35mm) plug may be of a TRS (tip-ring-sleeve) balanced or a TS (tip-sleeve) unbalanced configuration.
- Instrument/Line switch for channel 1. Select to optimize the level and impedance for a 1/4″ (6.5mm) signal source.
- Input Channel 2 – This input accepts both XLR and 1/4″ (6.35mm) style plugs. Connect a microphone, instrument, or line-level signal source here. The 1/4″ (6.35mm) plug may be of a TRS (tip-ring-sleeve) balanced or a TS (tip-sleeve) unbalanced configuration.
- Instrument/Line switch for channel 2. Select to optimize the level and impedance for a 1/4″ (6.35mm) signal source.
MONO/STEREO
- MONO mode sums channel 1 and channel 2 inputs to record left and right (useful for podcast interviews). STEREO mode passes channel 1 to record left and channel 2 to record right (for musical tracking or live stereo recording).
- POWER – This light indicates that Connect II is being powered by USB.
- PHONES – This knob controls headphone monitor volume.
- GAIN – This knob controls the gain (amplification factor) for channel 1.
- SIG – This light indicates that an audio signal is present on channel 1. CLIP – This light indicates that the signal may be overloading the channel
- GAIN – This knob controls the gain (amplification factor) for channel 2. SIG – This light indicates that an audio signal is present on channel 2. CLIP – This light indicates that the signal may be overloading channel 2.
- OUTPUT – This knob controls the LINE OUTPUT signal level.
- +48V – This light indicates that 48V phantom power is present at the XLR input connectors.
- Headphone output – Connect your monitor headphones here. This is a 1/4″ (6.35mm) TRS (tip-ring-sleeve) stereo jack.
- Kensington® Security Slot. Connect a Kensington® compatible security device here to help protect your interface.
- LINE OUTPUTS – These are the left and right line-level signal outputs. These jacks accept TS (tip-sleeve) and TRS (tip-ring-sleeve) 1/4″ (6.35mm) plugs.
- USB 2.0 Type-C connector. Use this to connect to your computer via USB.
- +48V – This switch enables +48V phantom power at the XLR input connector
