DSP Processing and Signal Flow

The diagram below shows the input signal flow and DSP processing per signal chain.

Signal chains and mix-points are described in the following sections.

All signal routing, processing, and level control (gain/volume), are accomplished using

software control from a PC connected to the MVC 121 Plus via the USB configuration port

or the RS-232 port. The DSP Configurator program provides complete control while the

SIS commands provide more limited control.

This section describes the signal processing including parameter ranges, and how to

mix inputs and outputs using the DSP Configurator control program. To install the DSP

Configurator program, see the Software Control section.

Mic/Line Input Signal Chain

Input signal chain GUI elements from left to right are as follows:

Mic/line inputs 1 and 2

• Gain (GAIN) — Mono gain control with a range from -18 to +60 dB includes a mute

button. Step resolution is 0.1 dB. A polarity switch (+ or -) is provided. Gain control is

provided pre-meter and mute control is provided pre-meter.
