Analogue outputs

Parent chapter  Previous page  Next page

 

Lyra provides four analogue output channels (two in Lyra 1) on TRS jacks, with dual switchable output level to allow connection to professional or consumer line-level equipment. The '+4dBu' setting produces professional signals with a nominal level of +4dBu and allows a maximum level of +18dBu (0dBFS).  The '-10dBV' setting provides consumer signals with a nominal level of -10dBV and allows a maximum level of +6dBu (0dBFS).  Connection to unbalanced equipment is automatically accommodated by a level-compensation 'bootstrapping' circuit.

 

In normal operation, the analogue outputs are fed directly with individual signals from the host PC or Mac; however, it is possible to feed the outputs from local digital mixers within the Lyra hardware if desired - this is described in the Output mixers section below.  Outputs may also be switched to follow the mixers of other outputs.

 

It is also possible to assign a level control to any desired outputs, primarily for use as a monitor volume control - this is described in the Assignable level control section below.

 

Setting of analogue output levels, as well as activation of output mixers and assignment of the level control are all managed in the Outputs tab of the Lyra Control Panel app.
