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.

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.
