2. Introduction

The SP1200 is a single-channel version of our popular SP2400 dual-channel microprocessor-based music controller. Having a single 200 watt power amplifier, it's designed for use in a variety of installations requiring high performance, flexible features, and ease of use. Examples of such installations are retail stores, restaurants, bars, and theme venues. The SP1200 provides one output that can be used for single-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 the zone with the Input Select buttons on the front panel. The boxes under the Input Select buttons 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 with priority activated, it overrides any other program source assigned to that channel or zone.

Each of the four input sources can be either stereo or mono, although output from the SP1200 is a combined mono signal of both left and right inputs. The zone has a 3-band program 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, the zone has a variable for adjusting the trigger threshold of the paging mic's ducking circuit. The paging mic operates in the zone when voice-activated. However, it can be assigned to operate over the entire system when manually operated with a switch connected to the

MIC CONTROL

connector.

The 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 the zone to compensate for increased or decreased noise levels. This way 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 (and the

AMP IN

connector when the jumper is

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

PAGING

connector

Audio expansion connectors are provided on the rear panel for connecting multiple SP1200s, 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 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 the zone. The 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 for installing an optional DSP card (SP-DSP1). 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.

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.

Each zone on both SP1200s are assigned the same AMP ADDRESS, so when “OFF” is selected on one SP1200, the DX8 signal at the Mic/Line Input is routed to the SP1200 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 SP1200 outputs by selecting 1, 2, or 4 on the SP1200 front panel.

Applications

A: Typical Mono Application

This diagram depicts a typical setup, using the SP1200 in a mono application. A Digital Satellite Service (DSS) is connected to Input 1, which also serves as the music-on-hold for the telephone system. A CD player and cassette deck are connected to Inputs 2 and 3 for general purpose music playback. A jukebox is connected to Input 4, which is configured for priority playback via switch #7.

An ambient mic is connected to provide paging level compensation for varying ambient noise levels in the room. This amplifier has been configured for 8-ohm operation.

AMP ADDRESS

B: Multiple SP1200s: Multiple Zones

In this example, two SP1200s are used in a system with two 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 unit/zone has a different remote control exclusively operates its own zone.

Room Combining—Zones

In this example, a dividing wall can be extended to divide the room into two. The Mackie Industrial DX8 is used to route independent source selections to each zone (Preset 1 on the Remote Controls), or common input source selections for both zones (Preset 2 on the Remote Controls).

Both zones are assigned the same AMP ADDRESS, so when “OFF” is selected on either SP1200, the DX8 signal at the Mic/Line Input is routed to both SP1200 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 SP1200 outputs by selecting 1 (global remote), 2 (tuner), or 4 (CD) on the SP1200 front panel.

Tips on Installing and Using the SP1200—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 SP1200:

CAUTION: When using multiple SP1200s that use the expansion bus, these switch

settings you can damage your SP1200(s). 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 or other device that needs priority, use Input 4 in Program Priority mode (set the

Connections

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. Then 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 (–).

The

MIC/LINE INPUT A is

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 +40 dB switches (and the PHANTOM switches) are in the up (OFF) position.

Connecting the Speakers

The speaker output connector is a twoconductor Phoenix-type, with a position-locking mechanism. Use 16 or 18 gauge wire for connecting the amplifier outputs to the speakers. If the amplifier output is configured for 8-ohm operation, connect the speakers' output directly to an 8-ohm load. The amplifier will deliver up to 200 watts. 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 down, 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).

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.

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 SP1200 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 SP1200 and the remote control.

AC Power Considerations

Each SP1200 draws an average of 3 amps of AC line current (@ 120VAC) when fully loaded and playing music with a relatively high crest factor.

Voltage Conversion

The SP1200 can be configured to operate at 115V AC or 230V AC. See Appendix C for instructions on how to change the operating voltage configuration.

Thermal Considerations

IMPORTANT: The SP1200 is convection cooled rather than fan cooled. This design

was chosen to avoid the requirement for periodic air filter maintenance, and to keep the insides of the SP1200 clean in dirty environments. This avoids blowing dirty, smoky air into it. Heat is drawn away from the amplifiers by the heatsinks and radiated through the cooling vents in the top cover. When installing the SP1200, be sure to allow sufficient air space around the top and rear of the amplifier to allow adequate cooling for the heatsinks. If installing in a rack,

rack space above and below the SP1200 for a vent, and at least 6 inches behind the chassis to allow proper ventilation.

leave at least one

If installing three or more SP1200s in a rack, use a fan in the rack to move cool air in and warm air out of the rack's enclosure. It may be necessary to provide a cool air intake fan at the bottom of the rack, and a warm air exhaust fan at the top (see Figure below).

If the amplifier should overheat, a thermal switch is activated that disengages the speaker output, allowing the heatsink to cool down. The

OVERLOAD

indicator on the front panel will also light to show that a protection circuit has been activated. Once the amplifier has cooled to a safe operating temperature, the thermal switch resets and reactivates the speaker output. If this should occur, identify the cause of the problem and take corrective action, such as providing better ventilation, installing a fan in the rack to move more air, making sure the amplifier is not overloaded with too low of a load impedance, etc.

Using Inputs 1-4

Connect the program sources to Inputs 1-4. These could include a CD player, tape deck, tuner, satellite feed, TV audio, jukebox, or an audio feed from a live band. All four program inputs use unbalanced RCA connectors and accept stereo linelevel signals.

Note: The Input Select buttons are labeled 1 through 4 on the front panel. The spaces below the buttons are sized to accept 1/4" labels from the Brother P-Touch Electronic Labeling System. Professional-looking labels can be made to clearly identify the program source connected to each input (visit www.brother.com).

There are no individual volume controls for Inputs 1-4. The SP1200 automatically adjusts the volume for each input using an AGC circuit (Automatic Gain Control). This provides the best signal-to-noise ratio and insures that the volume remains the same when you switch from one source to another.

Only one Input source can be selected at a time. When switching from one source to another, the previous source fades out while the new source fades in (digital crossfade), rather than abruptly switching between the two.

Input 1 and the DIRECT OUTPUT

Input 1 provides a direct line-level output that can be used for music-on-hold or other external applications. Connect a continuous music source (i.e., satellite feed, prerecorded background music, multi-disc CD player) to Input 1 and connect the

Refer to the “Connections” section on page 11 for information on wiring these connectors.

These connections allow a common program source to be available to all the SP1200s in a system. For example, prerecorded music that is used for music-on-hold can also serve as background music for an entire office building by setting the internal bus assign switches for Input 1 to the up position on the first SP1200.

Using the Paging Mic

The paging mic is used to make announcements over the system. If the paging mic is a condenser mic or other type of mic that requires phantom power, move the position. Otherwise, leave them switched up.

The paging mic can be voice-activated and is routed to all channels or zones. However, you have the option of activating it manually with an external switch. If you choose to use a switch for the paging mic, you have the additional option of assigning the paging mic to either Zone A or to all zones (if multiple SP1200s are used).

• For Zone A only, connect a (normally-open) switch between the the

PAGING MIC CONTROL

• For all zones in a system interconnected via the

EXPANSION ALL CALL CONTROL

• For maximum flexibility, connect two switches to the both selections available.

The paging mic can be configured to automatically turn down (duck, or attenuate) the music that is playing over the system so the announcement can be heard when using the VOX circuit. When an announcement is over, the music gradually returns to its original volume.

The music ducks fairly rapidly, attenuating the music 20 dB within 300 ms (milliseconds) of detecting a signal on the paging mic. When the signal on the paging mic stops, there is a 1500 ms (1.5 second) timeout period to make sure the announcement is over, and then the music ramps up to its original volume over the next 2.5 seconds.

Note 1: When manually activating the paging mic, there is no timeout period after the announcement ends. The moment you let go of the switch, the music begins to ramp up to its original volume.

Note 2: When the manual switch is off, the voice-activated ( still operational. Ensure that the threshold is set accordingly to prevent false triggering of the paging mic input when using

The ambient mic provides an “ear” for the microprocessor to gauge the ambient noise in the room and adjust the gain of the paging mic accordingly. When the background noise is relatively quiet, the paging mic gain is at its lowest level. If the background noise is relatively loud, the paging mic gain is at its highest level. If the background noise is somewhere in between, the paging mic gain is midway between its lowest and highest preset levels.

the ambient mic switch is on ( #8 up). Locate the ambient mic in an appropriate position to pick up the ambient noise in the room. It can be mounted on the ceiling or on a wall. Avoid placing the ambient mic close to the speaker over which the announcement is being made. Keep the ambient mic away from a constant noise source, such as a refrigerator or other mechanical device that emits a continuous noise. The best placement is where the mic can pick up an average representation of the ambient noise level in the room.

2. Turn off the SP1200, then turn it back on again while

pressing and holding the Input 2 button. This causes the ambient mic preamp level to appear on the meter.

3. Establish the highest noise level that you would

expect to have in the room using a pink or white noise source, or a music source. Input 1 is operational in this mode to use as a music source, if desired.

4. The ambient mic preamp gain trim is located just

above the ambient mic connector on the rear panel, through the unmarked hole. Adjust it with a nonconductive alignment tool until all the green LEDs on the meter are lit. Insure that no yellow or red LEDs are lit, which runs the risk of clipping the ambient mic preamp or ADC.

5. Press the “OFF” button when finished to return to normal operation.

8. Use the front panel Up/Down buttons to set the lower

level of the paging mic (how loud it is with very quiet background noise). It should be loud enough to be heard clearly throughout the coverage area.

9. Press the “OFF” button and the level is stored. The

third LED starts flashing faster.

10.Use the front panel Up/Down buttons to set the upper

level of the paging mic (how loud it is with very loud background noise). As a general rule, set this level as high as it will go before feedback (at the "0" mark if steps 3-4 above were followed).

11.Press the Input 3 button when finished to store the

level and return to normal operation.

12.Verify that the paging microphone’s volume is sufficient

to be heard over the background noise in the room.

Note: For best results, with the background noise level at a minimum, the paging mic volume should be approximately the same as the music volume.

13.If the paging microphone is not loud enough to be

heard over the background noise, verify that the ambient mic is properly placed to pick up an accurate representation of the background noise. If it is, it may be necessary to readjust the lower and upper levels for the paging mic gain (steps 6-11).

Zone A Output

The amplifier output on the SP1200 can be used with an 8-ohm impedance load, or to drive a 70V or 100V distributed system directly (also called constant-voltage systems).

Direct Speaker Connection

If the SP1200 is not being used in a distributed speaker system, you can reconfigure the amplifier to drive an 8-ohm load. Each amplifier can provide up to 200 watts into an 8-ohm load. See the "Internal Settings" section on page 13 for instructions on how to reconfigure the amplifiers.

Distributed Speaker System

When using the SP1200 in a 70V or 100V system, connect the speaker output directly to the distributed system. The SP1200 can directly drive a distributed system's speaker line without the need for an output transformer. The SP1200 can supply up to 200 watts into a 70V or 100V distributed system. Make sure the taps on the speakers in the system do not exceed a total of 200 watts.

Using the Remote Connection

The optional SP1200 Remote Control (SP-41R) provides Input Selection and Master Volume control for each amplifier or zone. The Remote Control can be mounted in a standard double-gang electrical box and covered with a Decora®-style faceplate.

Connecting One or More Remote Controls

Each Remote Control affects only the zone to which it is connected. Up to ten remote controls may be connected to each zone simultaneously. This allows controls to be conveniently placed. Each control will interact with the SP1200, and all controls will reflect the current source and level settings. Note that the remote control indicates the gain setting and not the actual signal level in real time. In addition, the SP1200 provides a method for controlling two independent zones using a single Remote Control by assigning them to the same

AMP ADDRESS

The maximum distance between the remotes and the SP1200 varies, depending on the type of cable selected and the number of remote controls used. Typically, a lower wire gauge and cable capacitance allow longer distances. See the instructions with the remote control for more information.

(see next section).

Using the RS485 Connection

The amplifier is equipped with an connection. When two SP1200s are linked via the RS485 connection and assigned to the same zone (AMP ADDRESS switches 1-5), the Input Selection and MASTER VOLUME buttons on both amplifiers track each other. One unit must have

and the other unit in the Slave position (down).

In this way, you can have one Remote control operate both amplifiers that are assigned to the same zone.

Using the SPLinker Sound Palette

Controller

The RS485 connection can also be used to connect the SP1200 to a computer loaded with the SPLinker software application. The PC-compatible computer must have an RS485 port to properly connect to the SP1200. It may be necessary to install an RS485 interface card, or use an RS232 port with an RS232-to-RS485 converter.

The SPLinker is a PC-based graphical interface to provide real-time monitoring and control (for up to 32 zones when used with SP2400s). It provides individual program source selection and volume control for each zone. Select boxes are located at the bottom of each zone for selecting multiple zones. All selected zones can then be modified at the same time in the Multiple settings box located on the right-hand side of the screen.

The

RS485

connection can also be used to interface with common third-party control systems. Contact the third-party provider or Mackie Industrial Technical Support to determine if your control system is compatible with the SP1200.

Upgrading the Software

From time to time, Mackie Industrial will release upgrades for the internal operating software in the SP1200. This can be downloaded from our website (www.mackieindustrial.com) to a PC-compatible computer. Use the serial port on the computer to connect to internal connector on the SP1200's CPU board to transfer the data to the on-board flash memory. Instructions will be provided when upgrades are available.
