Operation
is 1 ms and the release time is fixed to 1000 ms. Default limiter threshold level is
-3 dB. The red color LED in the front panel indicates that the limiter is activated, and
the audio level reached the threshold level.

DELAY
DSP allows adding delay to an audio signal in 0 – 500ms (0-170m.) range by using
1ms resolution.
Please note that the delay parameter in iAC 2x240 DSP can be adjusted for channel
1 (CH1) only, it also works in bridge mode. iAC 2x240 DSP amplifier's channel 2
(CH2) do not support delay.
INPUT GATE
→
The amplifier has an installed audio gate. This function mutes the amplifier if the
audio signal or noise in the input is smaller than the specifier threshold. Users can
enable or disable this function.
By default audio gate is enabled. The audio gate threshold is fixed to -56dBu.
SYNC SETTINGS
→
The iAC 2x240 DSP Sync function allows to link both channels and copy settings
from one channel to another to control both amplifier channels at once.
There is the option to copy CH1 settings t CH2 or copy CH2 settings to CH1
