SP2400

SOUND PALETTE® Series

The SP2400 is a dual-channel music controller
and amplier designed for installations requiring
high performance, exible 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 specic 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
