Description

This test verifies the operation of level trim and/or balance controls, if provided.

Method

Set all level trim/balance controls to their nominal positions.

The script will go through each channel in turn, and ask whether the channel has trim/balance

controls. If it has, then the test will be performed for the channel.

For each channel with level/trim controls, play track 30 and then click the

[OK]

button to start the test.

The nominal level of the channel wil be recorded and a Sweep performed. Increment the trim for the

channel by one step, then restart track 30 and click

[OK]

again. The Sweep will be repeated at this

new level. This process will be repeated again for the minimum and maximum level of the trim control.
