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.

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

Note: This application provides independent source selection for each zone, or common input source selection for both zones (room combining). Both DX8 Selection Remote Controls are used to select Presets 1 and 2.

For example, Preset 1 might route the CD Player and the Zone A microphone to Zone A, and the Cassette Player and the Zone B microphone to Zone B, to be used when the divider is in place between the two zones. Preset 2 might route both microphones and the audio signal from the laptop to both Zones A and B, to be used when the divider is removed between the two zones.

Both Zones on the SP2400 are assigned the same AMP ADDRESS, so when “OFF” is selected on the SP2400, the DX8 signal at the Mic/Line Input is routed to the SP2400 outputs. The local input sources (Tuner and CD 5-Disc Changer) or the Global Background Music via the Expansion I/O can be routed to the SP2400 outputs by selecting 1, 2, or 4 on the SP2400 front panel.

B: Multiple SP2400s: Multiple Zones

In this example, two SP2400s are used in a system with four separate zones configured for 70V operation (default configuration for U.S. versions). Four program sources are connected to Unit 1. Of these, only the DSS and Jukebox signals are shared with Unit 2 by means of the Expansion Bus (Inputs 1 and 4 are assigned to the Expansion Bus via the internal Bus Assign switches). Both units have sources connected to Inputs 2 and 3 that are exclusive and not shared between units. Each zone has a different remote control exclusively operates its own zone.

Tips on Installing and Using the SP2400—Plan Ahead!

The key to any successful installation is planning your system well in advance. Know which components are going to be used in the system, their locations, and how they will interface with each other. Plan the wire routing and AC power requirements.

Here are some steps to follow to help insure a smooth installation of the SP2400:

How many program sources are going to be

used?

If the number of program sources is four or less, they can be centralized at one SP2400 and distributed via the Expansion Bus. If there are more than four program sources, they must be distributed among the SP2400s. Determine the number and location of the program sources that are going to be used.

Determine which program sources are going to be used for each zone, and set the and internal

CAUTION: Never assign more than one program source to the same channel on the Expansion Bus.

If there is a requirement for music-on-hold, use Input 1 for the continuous music source (i.e., satellite feed, prerecorded background music, multidisc CD player). Then use the jacks to route the signal to the telephone system.

If there is a jukebox, use Input 4 in Program Priority mode (set the to activate). When a signal appears at Input 4 it overrides the selected Input source.

Using a chart similar to the one below can be very helpful in organizing the various components of the system:

PHANTOM

Connecting the Program Sources

All four Program Inputs use unbalanced RCA connectors. They accept line-level signals (–10 dBV). Each of the Program Inputs is equipped with an AGC circuit instead of input trim controls. These circuits automatically adjust the gain for the best signal-to-noise ratio according to the strength of the input signal. It also ensures that the relative volume level remains the same when switching between input sources.

Use high-quality, two-conductor shielded cable to make these connections.

Connecting the Microphones

If using the XLR input for the paging microphone, wire it per AES standard where pin 1 is ground (shield), pin 2 is signal high (+), and pin 3 is signal low (–). If using the Phoenix-type connector, strip the wire back about 1/4" inch, insert the wire as far as it will go into the appropriate hole in the connector, and tighten down the screw with a small slot-head screwdriver. It is recommended that you use 20 or 22 gauge wire with the Phoenix-type connectors, where pin 1 (the left-most pin) is ground (shield), pin 2 is signal high (+), and pin 3 is signal low (–).

microphone. This is a Phoenix-type connector, and is wired as described in the previous paragraph for the paging microphone.

All microphone inputs are equipped with a pad switch for use with line-level signals. When connecting a line-level signal to these inputs, make sure the GAIN +40dB switches are in the up position.

are for a local

Connecting the Speakers

The speaker output connectors are twoconductor Phoenix-type, with a position-locking mechanism. Use 16 or 18 gauge wire for connecting the amplifier outputs to the speakers. If

SP2400 – 11

Page 12

the amplifier output is configured for 8-ohm operation, connect the speaker output directly to an 8-ohm load. The amplifier will deliver up to 250 watts to each speaker. If the amplifier is configured for either 70V or 100V operation, connect the speaker output directly to the distributed system. No output transformer is required. Make sure that the taps on the speakers add up to 200 watts or less per amplifier for 70V or 100V systems.

Connecting the Expansion Bus

These are 25-pin D-Sub connectors (DB25F). The two connectors are wired in parallel, so it doesn’t matter which one you use as an input or output. The signals on the balanced so they can be transmitted down long lines. The limiting factor is the capacitance of the cable, which causes the higher frequencies to rolloff as the capacitance increases (see chart below). The chart indicates the lengths of cable at which the high-frequencies are 1 dB down and 3 dB, using cable rated at 20pf/ft and 30pf/ft.

Use shielded twisted pairs for the cable to ensure the best rejection of external noise (EMI and RFI).

Expansion Bus Connection Chart

Distance Chart for SP2400 Expansion Bus Cable

For local interconnection of the Expansion Bus, the use of standard computer cable with an overall shield is acceptable, such as Belkin Pro Series 25Conductor Straight-Through Cable Assembly (Part Number F3D111-06) or equivalent. Ensure that the cable is wired straight-through and terminated to DB25M connectors on each end.

Note: The use of ribbon cable is permissible for these connections, only where the total length of each cable is 12" (30cm) or less.

SP2400 – 12

Connecting the REMOTE Bus

This is a 3-pin Phoenix-type connector specifically for connecting the optional remote control. Use a high-quality three-conductor shielded cable to make this connection, such as Belden 8451, 9451, or equivalent. The lower the nominal capacitance of the wire, the more distance you can have between the remote control and the SP2400 before suffering transmission losses.

Strip the wire back about 1/4 inch, insert the wire as far as it will go into the appropriate hole in the supplied Phoenix-type connector, and tighten down the screw with a small slot-head screwdriver. It is recommended that you use 18 to 24 gauge wire for the remote control connections, depending on the distance between the SP2400 and the remote control.

The

REMOTE

connector is wired as follows: Pin 1 = Ground (Shield) Pin 2 = Data + (with +24V DC power) Pin 3 = Data – (with +24V DC power)

Note: See the instructions with the remote

control for more information.

Connecting the RS485 Serial Port

This is a 3-pin Phoenix-type connector that

follows standard RS485 protocol. Select either a data-grade shielded twisted pair cable or a standard 3-conductor microphone cable for this connection.

The

Bus Assign

There are two 8-position DIP switches on the Input Board that allow you to assign a Program Input source to the balanced expansion bus. Each Program Input Source has four corresponding switches: Left (+), Left (–), Right (+), and Right (–). Typically, you would move all four switches either down (off) or up (assign to expansion bus).
