Voltmeter Channel (L.In, R.In, L.Out, R.Out) Controls: Options >> Voltmeter >> L.In-R.Out
These four radio pushbuttons select the channel to be measured. (See the Multiple Meters Mini-App to simultaneously monitor up to two inputs and two outputs.) The buttons are labeled L.In, R.In, L.Out, and R.Out. If you are using Multi-Channel Outputs, use the Monitor As buttons to select which output channels will be reported as Left and Right Out. Note that the output channels include any DC Offset you may have added to an output Generator stream, even though almost all sound cards are AC-coupled to remove all DC prior to the final outputs. Input channels have already passed through an AC-coupled stage and will thus show only the residual DC, if any, from internal preamplifier stages. See DC Measurements And Outputs for ways to get true DC input response. If you are using an Arduino board with the DaquinOscope macro mini-app to measure DC voltages, and its Channels control is set to 1, the L.In button will be replaced with Ch0. If it is set to monitor two channels then R.In will similarly be replaced with Ch1, while for 4 channels the buttons will be labeled Ch0 through Ch3. Macro Notes: Use VoltCh=LI to select Left Input, RI for Right Input, LO for Left Output, and RO for Right Output. Alternatively, you can use numeric values, variables, or expressions instead of mnemonic names: 0 = LI 1 = RI 2 = LO 3 = RO Note that if you use a mnemonic in an {\b IF} test, it must be in quotes: IF.VoltCh="LI".
