I purchased the unit from a private party and the original owners manual was not available. Having the ability to download it was extremely helpful and clarified operating the equipment immensely. This is a complicated unit and without the manual I would not have been able to maximize it's potential. Thank you.
Being a user of older radios of many kinds, preferring them over more modern rigs, this manual was invaluable in the programming of my two. I now know for certain what the assorted buttons functions are, and am very grateful to have found this excellent site. Many thanks for your assistance, Tony.
5 star quality on these downloadable manuals. Easy to read and all the information is there. A must when doing a custom install or needing to service your precious old school electronics.

Mastering Tool Kit Parameter Functions
Expander
This expands the dynamic range at a fixed ratio.
Compressor
OFF, ON -80�0 dB
This compresses the overall output signal when the input volume level exceeds a set value.
On/Off
This setting turns the expander on/off.
On/Off
This parameter turns the compressor effect on/off.
OFF, ON -24�0 dB
Lo Thres
This sets the volume level at which the lower-range expander goes into effect.
Lo Thres
Lo Ratio
1:1.00�1:16.0, 1:INF
This sets the volume level at which the lower-range compressor goes into effect.
This sets the ratio of increase in output of the lower range when the input level falls below the Lo threshold level.
Lo Ratio
1:1.00�1:16.0, 1:INF
Lo Attack
0�100 ms
This sets the ratio of suppression of the lower-range output when the input level exceeds the Lo threshold level.
This sets the time it takes for the lower-range expander to go into effect once the input level falls below the Lo threshold level.
Lo Attack
0�100 ms
Lo Release
50�5000 ms
This sets the time it takes for the lower-range compressor to go into effect once the input level exceeds the Lo threshold level.
This sets the time it takes for the lower-range expander effect to stop once the input level exceeds the Lo threshold level.
Lo Release
50�5000 ms
Mid Thres
-80�0 dB
This sets the time it takes for the lower-range compressor effect to stop once the input level falls below the Lo threshold level.
This sets the volume level at which the midrange expander goes into effect.
Mid Thres
-24�0 dB
Mid Ratio
1:1.00�1:16.0, 1:INF
This sets the volume level at which the midrange compressor goes into effect.
This sets the ratio of increase in output of the midrange when the input level falls below the Middle threshold level.
Mid Ratio
1:1.00�1:16.0, 1:INF
Mid Attack
0�100 ms
This sets the ratio of suppression of the midrange output when the input level exceeds the Middle threshold level.
This sets the time it takes for the midrange expander to go into effect once the input level falls below the Middle threshold level.
Mid Attack
0�100 ms
Mid Release
50�5000 ms
This sets the time it takes for the midrange compressor to go into effect once the input level exceeds the Middle threshold level.
This sets the time it takes for the midrange expander effect to stop once the input level exceeds the Middle threshold level.
Mid Release
50�5000 ms
Hi Thres
-80�0 dB
This sets the time it takes for the midrange compressor effect to stop once the input level falls below the Middle threshold level.
This sets the volume level at which the upper-range expander goes into effect.
Hi Thres
-24�0 dB
Hi Ratio
1:1.00�1:16.0, 1:INF
This sets the volume level at which the upper-range compressor goes into effect.
This sets the ratio of increase in output of the upper range when the input level falls below the Hi threshold level.
Hi Ratio
1:1.00�1:16.0, 1:INF
Hi Attack
0�100 ms
This sets the ratio of suppression of the upper-range output when the input level exceeds the Hi threshold level.
Section 4
This sets the time it takes for the upper-range expander to go into effect once the input level falls below the Hi threshold level.
Hi Attack
0�100 ms
Hi Release
50�5000 ms
This sets the time it takes for the upper-range compressor to go into effect once the input level exceeds the Hi threshold level.
This sets the time it takes for the upper-range expander effect to stop once the input level exceeds the Hi threshold level.
Hi Release
50�5000 ms
This sets the time it takes for the upper-range compressor effect to stop once the input level falls below the Hi threshold level. * With the compressor, the level is automatically adjusted to the optimum setting according to the threshold (Thres) and ratio (Ratio) settings. In addition, since lengthening the attack (Attack) setting may result in distortion, a buffer (margin) of -6 dB is provided. Adjust the mixer (Mix) level as needed.
