Mackie SP2400 quick start Dual-ChannelProgram Controller/Amplifier, Safety First

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.

(continued from page 1)

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 can be independently assigned to the balanced bus with internal assign switces. The LOCAL/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.

Quick-Start Guide

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 between the local program input and the remote EXPANSION IN bus. 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).

STEREO/MONO switches configure each input source for either stereo or mono (zone) 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

A wired remote control is available that can select the input source and adjust the volume level for each zone. The remote control fits into

adouble-gang electrical box with a Decora®- style faceplate.

The RS485 port can interface with third- party 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 (SP-DSP1). It provides additional ambient noise sensing for the Program Inputs, using the optional ambient microphone. An RS232 port (COMM PORT) is provided on the front panel for connecting a Palm™ Handheld or PC computer for configuring the optional DSP card.

EXPANSION I/O

The SP2400 is a microprocessor-based dual-channel music controller with two built-in power amplifiers designed for use in a variety of installations 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. Each of the four inputs can be operated in either stereo or mono mode, and 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

Each mic/line input has a 40 dB gain switch, variable gain trim, phantom power switch, and a two-band EQ. In addition, each zone has a variable VOX control 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 in both Zones when manually operated with a switch connected to the PAGING MIC CONTROL connector.

Each zone is equipped with an input for an optional ambient microphone that can sample the ambient noise level in the room and adjust the paging mic gain in each zone to compensate for increased or decreased noise levels.

Internal jumpers are provided for configur- ing the amplifier outputs for 70V, 100V, or 8- ohm operation. The SP2400 ships configured for 70V operation (U.S. versions).

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 (U.S. versions). Internal jumpers are provided to configure the amplifier for 8-ohm, or 100 Volt systems.

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.
