5) LED array
Power
Indicates that AC power is connected and the amplifier is turned on.
DSP limit
Indicates that the DSP protection circuitry is limiting the signal, thus preventing digital clipping.
Soft clip
Indicates that the analog soft clipping circuit in the poweramp section is active.
A soft clipping circuit clips short signal peaks in a way that is not sounding unpleasant to your ears.
Although a soft clipping circuit limits your dynamic range, it allows you to operate on higher volume
levels.
Protect
Indicates an electrical or thermal fault condition in the power amp
6) Volume
Use to adjust the input volume level for the LT-218BA.
7) RS-485 Termination (only in older units)
Allows you to switch the RS-485 termination on or off. The last device in a RS-485 setup should always
have a termination resistor connected. If you’re using only one device in a RS-485 setup make sure
that the termination switch is pressed in.
8) RS-485 control sockets
Allows you to control one or more devices from the LT-series using your computer and the included
software. You can connect up to 32 devices.
