Both analogue input channels feature balanced line inputs on TRS jacks, with dual switchable sensitivity to allow connection to professional or consumer line-level sources. The '+4dBu' setting accommodates professional signals with a nominal level of +4dBu and allows a maximum level of +18dBu (0dBFS). The '-10dBV' setting accommodates consumer signals with a nominal level of -10dBV and allows a maximum level of +6dBu (0dBFS).Unbalanced sources are automatically accommodated.
Both input channels of Lyra 2 (but only input 2 of Lyra 1) have balanced XLR microphone inputs, with gains variable from 10dB to 65dB in accurate 1dB steps, and with individually switchable phantom power. A -20dB pad may also be selected if required.
Both input channels of Lyra 2 (but only input 1 of Lyra 1) have high-impedance front-panel unbalanced 6.3mm instrument ('DI') jacks, also with fine and accurate gain control.
Selection of input modes may be automatic: where mic input mode is over-ridden by the insertion of a line jack, and both are over-ridden by the insertion of an instrument jack. Alternatively, input selection may be set manually irrespective of which jacks are inserted.
The input mode and phantom power state of the input channels is indicated on the front panel of the unit, and also in the Inputs tab of the Lyra Control Panel app. Line, mic and instrument gains are also adjusted in the Inputs tab, as is selection of the Overkiller, high-pass filter and MS matrix functions described in the following sections.
