Features and Notes

Dual Audio Mixer w/ phase switch (2-3x1) (MIX2)

The Serge Dual Audio Mixer (MIX2) contains two independent mixers for audio signals. [Each section has three inputs with level control knobs]. [The top section is a three-in/one-out manual mixer with a phase switch on input 3]. [The bottom] section is a four-in/one-out manual mixer [with an additional] unity gain (non-attenuated) input. The main output of one section can be connected to the unity gain input of the other section to create larger mixing units. This module can be used as two audio mixers with three variable inputs, or as one mixer with six variable inputs. Used in combination with other mixers and VCA modules, various mixing functions can be patched.

Wizardry: As with the Dual Processor, you can use this module to realize greater than unity gain. Plug your incoming audio into one input, then multiple that banana plug into the next input. You can also get some subtle signal distortion this way.

Dual VCA (2VCA)

The DUAL VCA (2VCA) employs two high-quality VCA's. This module is an excellent inter-patch VCA, featuring very low noise and exponential response. It was designed as a small VCA function for use at various places within a system for internal VCA functions (as opposed to the VCA's for output mixing). Like the new Universal Audio Processor and the Cross-Fader this VCA has an audio taper that is an exponential curve with a 12 db per volt sensitivity throughout the range except below about .5 volts. Below this threshold, the output of the VCA will decrease rapidly to completely attenuate the signal. This response is perfect for our envelope voltage range. and is responsible for exceptionally quiet operation. Control voltage rejection is very high, and the unit cannot be overdriven beyond a gain factor of two.

Quad Channel Stereo Mixer (4x2) (QVM)

The QUAD INPUT VOLTAGE CONTROLLED STEREO MIXER (QVM) is an excellent low noise mixer for small to medium size Serge systems, since it incorporates an equal power stereo panner as well as a voltage controlled amplifier for each of four inputs. Both signal level and spatial location can be controlled manually or by voltage control. The Mixer is also well suited for external computer control and for automated mix-downs with voltage programmable spatial positioning. Two or more Quad Input Stereo Mixers can be connected together conveniently to form mixers of eight, twelve, or more inputs by connecting the outputs of one to the auxiliary inputs of another. Outputs and Auxiliary inputs are provided with mini-jacks in addition to banana jacks to facilitate hook-up to external audio equipment.
