Features and Notes

Matrix Mixer (MAX)

The MATRIX MIXER (MAX) is a four-in/four-out mixer with maximum versatility. Each input has four knobs which separately control the level of that input at each of the four outputs. This operation requires the four-by-four matrix. Four additional knobs are included to control the total output level of the four outputs. This arrangement allows the user to set four independent mixes with a separate output level control. Thus, each of the four mixes can be adjusted for the proper output level without affecting the balance of the four input signals. The first two inputs include a phase switch.

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.
