The Model 227e System Interface facilitates the equalization, spatialization, mixing, and routing of audio signals in four-channel studio or performance environments.
A total of nine signal inputs are provided. Four are primary inputs, and can be individually located in two-dimensional space under voltage control. Automated movement around a four-channel (quad) space can be implemented with voltages controlling rate, direction, and radius. LED indicators display activity and aid in bus assignment.
Another four inputs appear as a separate, independent four-channel mixer with a single output; these inputs may optionally be connected to the four main outputs. A microphone preamplifier with envelope detector is also provided.
Equalization can be applied to front and rear channels; a spectral tilt function is introduced that compensates for the high treble energy as needed. Individual EQ masters for front and rear are also provided. Monitoring facilities include VU meters on each channel and a headphone driver for front, rear, or all channels.
Certain parameters of the 227e can be stored as part of 200e series setups using the Preset Manager on the 225e or 206e modules.
The 206e offers a six input, two output mixer with controls for level and stereo location (pan position) on each channel. The 206e also incorporates a Preset Manager. This can be used either as the primary Preset Manager for storing and recalling nearly all system variables, or as a secondary Preset…
The Model 267e combines a noise source, a random voltage source, and a simple two channel filter. Noise comes in three flavors. White noise is electrically flat, but acoustically balanced toward the high end of the spectrum (+3 db/octave).
