WARNING! This equipment has been

designed to be installed by qualified

professionals only! There are many factors to

be considered when installing professional

sound reinforcement systems, including

mechanical and electrical considerations, as

well as acoustic coverage and performance.

Mackie Industrial strongly recommends that

this equipment be installed only by a

professional sound installer or contractor.

SP2400

Dual-Channel Program Controller/Amplifier

Quick-Start Guide

The SP2400 is a microprocessor-based

dual-channel music controller with two built-in

power amplifiers designed for use in a variety

of installations such as retail stores, restaurants,

bars, and theme venues. It provides two outputs

that can be used for either stereo operation or

two-zone coverage. Four stereo line-level inputs

are provided on the rear panel, along with a

paging mic input and two local mic/line inputs.

The program input sources can be

independently assigned to each zone with the

Input Select switches on the front panel. Each

of the four inputs can be operated in either

stereo or mono mode, and has an integral AGC

circuit to automatically compensate for level

differences between the input sources. Input 1

has a buffered line-level output that may be

used for music-on-hold or other external

applications. Program Priority can be assigned

to Input 4 for use with a jukebox or alternative

paging configurations.

Each mic/line input has a 40 dB gain switch,

variable gain trim, phantom power switch, and

a two-band EQ. In addition, each zone has a

variable VOX control for adjusting the trigger

threshold of the paging mic's ducking circuit.

The paging mic operates in both zones when

voice-activated, but can be assigned to operate

in either Zone A or Zone B, or in both Zones when

manually operated with a switch connected to

the PAGING MIC CONTROL connector.

Each zone is equipped with an input for an

optional ambient microphone that can sample

the ambient noise level in the room and

adjust the paging mic gain in each zone to

compensate for increased or decreased noise

levels.

Internal jumpers are provided for configur-

ing the amplifier outputs for 70V, 100V, or 8-

ohm operation. The SP2400 ships configured

for 70V operation (U.S. versions).

(continued on last page)

REMOTE is a 3-pin Phoenix-type connector

for the optional wired remote control

(SP-41R), which provides Input Select

and Master Volume control.

EXPANSION IN/OUT consists of two

parallel 25-pin D-Sub connectors for

connecting multiple SP2400s together in a

serial fashion. Any of the four program

sources from any SP2400 can be used as

the source for any of the zones in the

system by assigning it to the expansion

bus with the internal Bus Assign switches.

This is a balanced bus for the four stereo

input sources. In addition, the paging mic

and paging control signal are also

provided on the EXPANSION bus.

LOCAL/REMOTE is a set of eight DIP

switches used to select the input source

for the channel between the local program

input and the remote EXPANSION IN bus.

Each program input has two switches, one

to select the left signal source (odd-

numbered switches) and one to select the

right signal source (even-numbered

switches).

STEREO/MONO switches configure each

input source for either stereo or mono

(zone) operation.

PRE OUT is an unbalanced RCA jack that

provides a line-level signal from the

preamplifier stage of the SP2400. This

provides a method for inserting an

external signal processor into the signal

chain prior to the amplifier stage. The U-

shaped jumper wire should remain

installed between the PRE OUT and AMP

IN jacks for normal operation.

AMP IN is an unbalanced RCA jack that

accepts a line-level signal. See PRE OUT

above.

ZONE A/ZONE B OUTPUTS are 2-pin

Phoenix-type connectors that provide

speaker-level signals. The SP2400 is

shipped with the outputs configured for

70 Volt operation (U.S. versions). Internal

jumpers are provided to configure the

amplifier for 8-ohm, or 100 Volt systems.

Connect the supplied AC linecord to the

IEC AC Socket. The AC line fuse is

contained in the socket, behind the cover

located at the bottom of the socket. Use

replacement fuses only as indicated on

the rear panel.

1. Never install, connect, or disconnect

the unit with the power supply on.

2. Before powering up the SP2400, make sure

the AC voltage applied corresponds to the

markings on the rear panel.

3. Make sure the safety ground on the

power cord is properly grounded.

4. To prevent the risk of electric shock,

never open the unit. There are no

user-serviceable parts inside.

5. To ensure normal cooling of the

SP2400, make sure the unit is well-

ventilated. Avoid exposure to direct

sunlight or proximity to any heat

source, dust, or dampness.

6. If installed in an equipment rack, provide at

least one rack space between each SP2400,

and install a fan in the rack if three or more

SP2400s are mounted in a single rack.

(continued from page 1)

Audio expansion connectors are provided

on the rear panel for connecting multiple

SP2400s, with shared audio via balanced

busing. Each of the four program input signals

can be independently assigned to the

balanced bus with internal assign switces. The

LOCAL/REMOTE switches on the rear panel are

provided for selecting either local or bus

operation for each input. The paging mic and

paging control signal are also carried over the

expansion bus.

A wired remote control is available that can

select the input source and adjust the volume

level for each zone. The remote control fits into

a double-gang electrical box with a Decora

style faceplate.

The RS485 port can interface with third-

party control systems, or a PC-compatible

computer loaded with the SPLinker software

application for computer control of up to 32

zones in a system.

An internal option slot is provided on each

of the two channels for installing an optional

DSP card (SP-DSP1). It provides additional

ambient noise sensing for the Program Inputs,

using the optional ambient microphone. An

RS232 port (COMM PORT) is provided on the

front panel for connecting a Palm™ Handheld

or PC computer for configuring the optional

DSP card.
