| ## MU1 - Quick guide
| MU1 is a simple Jack app used to organise stereo monitoring. It was written originally for use with Ardour2, but still useful with Ardour3 as it provides some extra functions. Main features: * Four stereo inputs. * K20 RMS/peak meters and stereo correlation meter. * Two monitoring outputs with individual volume controls. * Left / Right / Mono and Dim swithes. * Output of unmodified selected input, e.g. for metering. * Talkback level controls and buttons with automatic dimming of speakers. Main controls are declicked cq. dezippered.
| The rotary knobs can be used in two ways: * Click on the knob with the left mouse button, keep it pressed and move either left..right or up..down. * Using the mouse wheel. Press Shift for smaller steps. From Left to right we have: * Input selection. Select on of the four stereo inputs. Normally these act as radio buttons, but you can add/remove an input without affecting the others using R-click. * Lef/Right/Mono switches. L and R use a single speaker, as they are sometimes used to check the speaker rather than the signal. * Dim switch. Decreases output level by 25 dB, e.g. when answering the phone. * Output 1 controls. Volume and on/off switch. The on/off switches act like radio buttons, R-click to activate more than one. * Output 2 controls. Volume and on/off switch, for a second set of speakers or headphones. The HP switch introduces some frequency-dependent crosstalk that makes headphone listening more natural, in particular if you have some sounds hard panned left of right. * K20 meters and stereo correlation meter. A peak memory is shown in the right down corner, click to reset. * Talkback buttons and level controls. Two separate talkback circuits are provided. The buttons are momentary when using the L mouse button and latching when R-clicked. Talkback automatically dims the monitoring outputs.
