Mackie SP1200 user service LOW High Priority, Risk of Fire Replace with Same Type Fuse and Rating

The PAGING MIC VOX variable control adjusts the ducking threshold for the paging mic. Rotate the control clockwise to reduce the threshold. Rotate the control counterclockwise to increase the threshold.

MIC/LINE INPUT is provided to connect a local microphone. 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. 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.

EQ 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 the 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 the 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 SP1200s and SP2400s.

When two SP1200s are linked via their RS485 connectors and assigned the same AMP ADDRESS (switches 1-5), the front panel controls and remote controls operate both amplifiers.

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 SP1200s and SP2400s together in a serial fashion. Any of the four program sources from any SP1200 and 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 each input. 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.

PRE OUT is an unbalanced RCA jack that provides a line-level signal from the preamplifier stage of the SP1200. 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 OUTPUT is a 2-pin Phoenix-type connector that provides speaker-level signals. The SP1200 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.
