5.3.6. Adjusting the speaker line's ShORT sensitivity
SHort sensitivity is expressed as the ratio to the initial value (defined as 100 %) and can be adjusted in the
range of 5 % to 50 %. It is set to "50" (the indicators at the top light) for all the channels by default.
Note
moving the setting closer to 5% decreases the SHort sensitivity, and thereby stabilizes the operation of the
"SHort" detection.
Important
Adjust the SHort sensitivity within the range not exceeding two times the power amplifier's rated load, as
doing otherwise may cause damage to the power amplifier.
(Example)
• When the speakers with the rated load are connected: Set to "50."
• When the speakers with 1/2 rated load are connected: Set in the range of "25" to "50."
