The SP-DSP1 is a
real-time digital
signal processor that
can be installed in
the SP1200 or
SP2400. It uses a
proprietary algorithm
to sense noise in a
room and adjust the
gain of the program
source accordingly.
This unique approach effectively "nulls out"
the music sensed at the ambient microphone,
allowing the DSP to measure the actual
ambient noise level in the room. As the noise
level increases, the gain of the music
automatically increases to compensate for the
increased noise.

Safety First!

Before installing the SP-DSP card, please
read this Quick-Start Guide carefully and keep
it for future reference.
CAUTION! This circuit board is
static sensitive, and is packed in
an anti-static bag. Please use
anti-static precautions when
handling the SP-DSP card, such as the use of
an electrically grounded wrist band and anti-
static mat.
WARNING! These servicing
instructions are for use by
qualified personnel only. To
avoid electric shock, do not
perform any servicing other than that
contained in the Operating Instructions

unless you are qualified to do so. Refer all
servicing to qualified service personnel.
Make sure the power is off and the power cord
disconnected before removing the top cover to
gain access to the inside of the SP2400.
Mackie Industrial strongly recommends that
this circuit board be installed only by a
professional technician, sound installer, or
contractor with electronic servicing experience.
1. Never open the SP1200/SP2400 with the
power supply on.
2. After installing the SP-DSP1 card, and before
applying power to the SP1200/SP2400,
make sure the cover is properly installed
and that no wires are pinched between the
cover and chassis.

    Installing the SP-DSP1 Card Note: These instructions describe how to install one SP-DSP1 into the Zone A side of the SP2400. A second SP-DSP1 may be installed in the Zone B side. The instructions for Zone B are the same unless otherwise indicated.
  • Page 3 R128 R127 STANDOFFS SP2400 FILTER BOARD 7. Place the SP-DSP1 circuit board on top of the four standoffs so the four holes in the DSP board align with the standoffs. The large square multi-pin integrated circuit should be on the right side of the board when facing the front of the unit.

    Using the SP-DSP1 Card It is important to understand that the SP-DSP1 does not add gain to the signal path, but rather attenuates the signal at its input by a user-adjustable amount, and then applies...
  • Page 5 This can never exceed the Minimum Gain (MG) setting. PO (Program Output) This indicates the output level from the SP-DSP1. The Program Output is equal to the Program Input (PI) level plus the Program Gain (PG).
