Owner manual

If one presses and holds the input select button a second time it will enable the input
gain trim mode. It requires about one half second of hold time to enter the trim mode.
Trim mode allows changing the input level on the selected input relative to all other
inputs. Gain trim has an offset range of plus or minus 10 db in 1 db steps. By pressing
the input button a third time, the input will return to normal operation while remembering
the gain trim. Selecting any other input will also exit the trim adjust mode.
Gain trim can be cleared, locked or enabled by using the Shift key to reach the desired
selection.
The mono function also has a gain trim for level matching in surround. After selecting
mono, if one presses and holds (for one half second) the mono select button it will enter
the input gain trim mode. To leave the gain trim mode press and hold the button for one
half second. Pressing the button for less time will cause the gain trim to be remem-
bered and the mono mode to be exit.
In normal operation all input gains will track. At the end of the stepped attenuator range
the offset gains could reach a limit where they will not change. As an example if you
trim an input up by 10 db and then move the main gain to max that input will be max
+10 which is not possible. Bringing the main gain back down, the 10db offset will still
exist. The same thing will happen on the bottom end of the control range.
