Notes: This useful module is a Bipolar Mixer, DC voltage source and Linear DC coupled VCA.

- With no input to channel 1 the Input 1 pot becomes a voltage source with a range of +/- 6V.
- The control pot and input for channel 4 can be switched to become an offset control and/or a second CV input for the VCA.
- Input 3 has 2x gain, so it can amplify lower level CV's too.
- All inputs are bipolar, which means that either non-inverted or inverted version of the input signal can be added to the mix depending upon the Input control being turned clockwise (non-inverting) or anti-clockwise (inverted). The 12'o'clock position is zero.

Notes: Five-channel mixer with mutes, built-in VCA, switchable overdrive and LED level meter. Simple, straightforward, high-quality stuff from AJH.

Supplier's Notes:
The MiniMod Muting Mixer & VCA is a 10HP wide, five channel audio mixer with many useful features. It is available with either a black (Dark Edition), or a silver front panel.

The mixer section has five input channels, and each channel includes a bi-colour tactile LED switch that can instantly mute or un-mute the channel, replicating the oscillator on/off switches on the original Model D synthesiser. This arrangement is more convenient than regular switches as each illuminated switch shows the on/off status of the associated channel and multiple buttons can be pressed at once, making it very useful for live performance.

AJH have also included a four segment LED level meter so that the overall level can be seen at a glance and adjusted to prevent the output from getting too "hot" and causing distortion in other modules further downstream.

It also features a VCA that is integrated into the output section, and this can be switched from linear to exponential response - this allows it to be used as a voltage controlled sub mixer or as a stand alone VCA with five inputs.

Lastly, AJH added a wonderfully soft and warm sounding overdrive circuit that can be switched in to add smooth, tube like distortion. This works in a similar fashion to a master volume guitar amplifier, so the amount of overdrive can be varied widely with different settings of channel and master output levels.
