The SP2400 is a dual-channel music controller
and amplifier designed for installations requiring
high performance, flexible features and ease of use.
Four independent stereo, line level inputs are
provided for connection of standard music sources,
such as CD, Tape, Satellite Receiver, etc. Each input
is terminated to dual RCA connectors. An integral
AGC circuit automatically compensates for level differences between input sources. A three band EQ,
with sweepable mid-range control is provided for
equalization of the music sources. In addition, an
internal option slot accepts specific EQ modules
designed to enhance the response of various speaker
systems. A dynamic loudness circuit boosts bass
response at low volume levels, to ensure proper
tonal balance. Music Input 1 is buffered to a stereo
RCA output that may be used for music-on-hold or
other external applications.
One input is provided for a paging microphone,
and is terminated to both removable Phoenix-type
and XLR connectors. Two band EQ, variable gain and
switchable phantom power are provided. A variable
VOX sensitivity control allows precise setting of trigger threshold points. Page Mic activation and music
ducking can also be activated by using the supplied
contact terminals. An optional noise-sensing microphone can be used.
A second microphone input, per channel, is provided for voice reinforcement. This input is terminated to a Phoenix-type connector and offers two
band EQ, variable gain and switchable phantom
power. The gain of this input is independent of the
master levels set for the music sources, and is
adjustable by the master volume control when all
music sources are off. Settings of the microphone
and music levels are retained in memory, allowing
adjustment of one source without affecting the
other.
Operator controls provide four music source
selector buttons and one OFF button for each channel. LED ladder display indicates relative level setting. Push buttons are provided for volume UP and
DOWN. All control setting changes can be made from

optional remote controls. A three-wire remote control bus allows connection of up to 10 addressable
remotes on one pair of shielded microphone cable.
Each remote can be set to control either of the two
channels.
The output section of the SP2400 offers two discrete amplifiers, each delivering 200 watts of RMS
power into either 70/100Volt line or into 8Ω loads.
The transformerless design of the amplifiers allows
frequency response to 20Hz, without the distortion
and losses typical of conventional designs. The two
amplifiers may be operated independently as two
zones, or as one stereo amplifier.
All of the SP2400’s functions are under microprocessor control and management. An RS485 port
is provided on the rear panel to allow interconnection with industry-standard control systems. Up to
eight SP2400 units may be interconnected, to share
four music sources and control data.
This Mackie Industrial product is covered by an
exclusive, one-time NO FAULT repair policy in addition to a three-year limited warranty.
