2. INTRODUCTION

The SP2400 is a microprocessor-based dualchannel music controller with two built-in power amplifiers designed for use in a variety of installations requiring high performance, flexible features, and ease of use, 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. The boxes under the Input Select buttons on the front panel are sized to accept Brother P-Touch® labels. Each of the four inputs 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. When a signal is detected at Input 4, it overrides any other program source assigned to that channel or zone.

Each of the four input sources can be operated in either stereo or mono mode. Each zone has a 3band EQ with sweepable mid for tuning the four program sources.

Each mic input has a 40 dB gain switch for use with either mic or line-level signals as well as a variable gain trim, phantom power switch, and a twoband EQ.

In addition, each zone has a variable 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 over the entire system when manually operated with a switch connected to the

PAGING MIC CONTROL

Each zone is equipped with an input for an optional ambient microphone that can sample the ambient noise level in the room. The microprocessor then adjusts the paging mic gain in each zone to compensate for increased or decreased noise levels so that the paging mic is always audible above the background noise.

The Master Volume Up/Down buttons adjust the overall level that is routed to the connector (and the

AMP IN

PRE OUT

connector when the jumper is installed). Internal jumpers are provided for configuring the amplifier outputs for 70V, 100V, or 8-ohm operation.

connector.

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 are internally balanced and can be independently assigned to the balanced bus with internal assignment switches. The

REMOTE

switches on the rear panel are provided for

LOCAL/

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 be used to select input sources and adjust volume levels for each zone. Each amplifier can be programmed with a unique address, and two amplifiers with the same address can be controlled by a single remote when interconnected by means of the RS485 port. The remote control fits into a double-gang electrical box with a Decora®-style faceplate.

In addition, the RS485 port can interface with thirdparty 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 (SPDSP). It provides additional ambient noise sensing for the Program Inputs using the optional ambient microphone. As the noise level in the room increases, the gain on the selected source gradually increases to keep the music audible above the background noise.

An RS232 port (

COMM PORT

) is provided on the front panel for connecting a Palm™ Handheld or PC-compatible laptop computer for configuring the optional DSP card.

PAGING MIC

is the connection for the paging microphone. There are two connectors available: a

CONTROL

is a Phoenix-type connector for

connecting external normally-open switches for remote paging. Three options are available: page to Zone A, page to Zone B, and page to the entire system (

PHANTOM

applies phantom power (+24VDC) to

pins 2 and 3 of the microphone input. Move both switches to the down position to turn on phantom power.

The

DIP switch is used to set the

gain for use with either a mic-level or a line-level signal. Move both switches to the down position for mic-level signals, and up for line-level signals.

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

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 (evennumbered switches).

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

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.
