SP2400 – 5

MIC/LINE INPUT

is provided to connect a local

microphone in each zone. This is a 3-pin Phoenix-

type connector where pin 1 is ground, pin 2 is signal

high (+), and pin 3 is signal low (–).

AMBIENT MIC

is a 3-pin Phoenix-type connector

used to connect the optional MT-3100 ambient

microphone, one for each zone. This microphone is

used to detect the ambient noise level in the room.

The microprocessor uses this information to adjust

the paging mic level above the ambient noise. The

ambient mic also provides an input for the optional

DSP card when it is installed.

is a 3-band equalizer with a sweepable

midrange that only affects Inputs 1-4.

LOW

is a

shelving filter that provides 15 dB of boost and cut

below 80Hz.

MID

is a peaking filter that provides

15 dB of boost and cut at the selected frequency

between 250Hz and 8kHz.

HIGH

is a shelving filter

that provides 15 dB of boost and cut above 12kHz.

AMP ADDRESS

is used to assign a unique

address to each amplifier, as well as to enable or

disable features. Switches 1-5 provide 32 separate

addresses, switch 6 determines Master/Slave

status, switch 7 enables Input 4 Priority, and switch

8 enables the optional ambient mic. Any two

amplifiers assigned to the same address can be

controlled by a single remote control when

connected together via the RS485 ports.

RS485

is a 3-pin Phoenix-type connector in each

zone that provides an interface for the SPLinker

Sound Palette Control PC application software for

centralized computer control of up to 32 zones, as

well as communication between SP2400s.

The RS485 interface is internally connected

between the two amplifiers, so if both amplifiers are

assigned the same zone with the

AMP ADDRESS

switch, the front panel controls and remote controls

operate both sides, ideal for stereo operation.

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.

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). Move the switches up to

select the local program source, and down to select

the remote (external) program source from the

EXPANSION

bus.

STEREO/MONO

switches configure each input

source for either stereo or mono operation. If the

SP2400 is being used in a stereo configuration,

leave the switches up. If it’s being used in a zone

configuration, move the switches down to combine

the left and right channels for mono 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 in U.S. versions, and 100-volt

operation in European versions.

Internal jumpers are

provided to configure the amplifier for 8 ohm

systems as well. See page 14 for more information.

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.
