Figure 38. Testing & Output Trim Tab
Several factors can affect the sound level reaching the listener from different speakers. These
factors include the distance from the speaker to the listener, slight variations between the output
channels of a single amplifier, and variations between the individual speakers. Use the output
trim to set the output level of each individual channel to compensate for all these variations and
ensure that the sound level reaching the listener is the same from all speakers.
This tab also provides a test signal utility.
Test signals
Test signals are used during setup to calibrate the level of
each channel and to ensure proper connection between the
individual output channels of the SSP 7.1 and the line level
input channels of an audio signal processor, a receiver with
built in amplifier, or a stand alone amplifier that powers the
loudspeakers.
