Chapter 4. Configuring the audio output.
Clicking on the speaker icon (or pressing ALT + 2 on Windows or Linux or CMD + 2 in MacOs) You can access the audio configuration panel.
The main audio output
On the left we have the main audio output, we will be able to control the general output volume of this virtual machine with the slider control.
Alternatively we will be able to control the output volume of the machine with the slide control in the upper control bar.
Using the Mute button You can mute the virtual machine.
Finally we can use the Reset button To reset the default output volume on all channels.
In the central part we find controls to individually configure each one of the channels of the virtual machine.
Please note that depending on which machine it is, some channels or others will be available.
For each channel we have two sliders, the vertical controls the volume of the corresponding channel. By means of the horizontal slider we will be able to configure the balance for this channel between the left and right.
Using the S button (solo) we can make the remaining channels deactivate and only the specified one is heard.
Using the M (Mute) button, you can mute a channel.
Stereo control on chips AY-891X
In the machines that have one or several chips AY-891X (the practice totality except the ZX Spectrum of 16K/48K as well as the Inves) we can select the mode of the stereo with the drop-down destined for that purpose.
The possible options are:
- MONO: All channels have centered balance
- ABC: (Default) channel A exits in the left channel, channel B by the two (center) and channel C to the right
- ACB: Channel A exits from left, B to right and C centered
The low pass filter
The sound in Retro Virtual Machine v2 comes through a low pass filter with the slider of the right we will be able to configure the frequency of cut of that filter.
