Input section:
Input source is selected from four different sources and is then routed through +/-10dB level, phase reverse and cut controls for both channels. Low Cut filters and High Cut filters follow, 20Hz-100Hz and 12kHz-27kHz, before the signal goes to the inserts.

Inserts:
The inserts are hard-switched, without adding electronics to the audio path. When an insert is not selected, its input receives signal from a separate feed. This assures isolation from the signal path but still provides signal for A-B comparisons. It also keeps compressors and other dynamic processors active.

Insert 1 can be switched to M-S (sum & difference). The left channel is the sum and the right channel is the difference. This function can be used to modify stereo images with equalisers, filters, compressors, de-essers, etc.
Insert 6 can be switched to POST FADER, moving it to after the output section.

Output section:
After the inserts, the signal is routed to the output section. FX Send and return is located at the input of this section. The output fader can be assigned to control the FX return. The stereo image can be modified with two controls:

1. Elliptical filter: This puts stereo signals, below 40Hz to 360Hz, into the centre of the image and cuts out-of-phase signals without altering the mono sound. The elliptical filter can be used for subjective (artistic) adjustments and is essential for analogue disk cutting.

2. Stereo width: This function adjusts the stereo width, +/-100%, without affecting the mono level. Not only can this improve stereo imaging, but it is also a powerful tool in combination with the elliptical filter (-100%=mono). Both stereo image tools are designed around a minimum electronic configuration and do not use M-S matrixes. They are 100% mono compatible.
