NEDSP1061-KBD Operating Manual
Note: The potentiometers do not have end stops. It is
possible to set the potentiometer in a dead band between
the ends, resulting in the audio being lost, continue
rotating and the audio will return.

Overload LED.
The overload LED circuit monitors the amplitude of the
audio level entering the DSP module. The LED will
illuminate when the amplitude exceeds the maximum
permitted level. If the amplitude is increased further the
DSP will clamp the audio signal to prevent damage to
the DSP input. This will cause the audio signal to become
distorted. The optimum level is achieved when the
loudest peaks of the input audio, just cause the LED to
glow.
2.5
Module mounting.
The DSP module has four mounting holes that can be
used to retain the unit inside the equipment. Alternatively
a self adhesive pad is supplied to allow the module to be
mounted in a convenient position - without the need for
drilling.
Two holes need to be drilled in the casing of the
equipment for the keyboard. Hole sizes and positions
can be found in section 7 - page 19.
The keyboard can retained using the supplied ‘Z’ bracket
or alternatively retained using a suitable adhesive, or the
mounting pads supplied.
In some equipment it may be possible to clamp the
bracket under the loudspeaker bracket (e.g. FT-817)
Cover the keyboard holes with the supplied self adhesive
label.
