USER MANUAL APG DYNAMIC PROCESSORS LPMC216 - LPDS8 - LPDS12S LDSP15 - LPDS15S - LPMX4 LP3000C - LPSC25
SAFETY INSTRUCTIONS This symbol alerts you to the presence of un-insulated dangerous voltage inside the enclosure – voltage that may be sufficient to constitute a risk of shock. This symbol wherever it appears, alerts you to important operating and maintenance instructions in the accompanying literature. Read the manual CAUTION: To reduce the risk of electrical shock, do not remove the cover (or back). No user serviceable parts inside; refer servicing to qualified personnel.

INTRODUCTION The LP processors provide all the necessary filtering, equalization, signal distribution and dynamic protection for the operation of APG loudspeakers and systems. They are designed to operate in conjunction with the Micro Axial Series, DISPERSION Series, BEAM Series & SECTOR Series and APG subwoofers. CONNECTING A PROCESSOR IN THE ELECTRO ACOUSTIC CHAIN Dynamic processors must be connected as the last element before the power amplifiers.
FILTERING AND SWITCHES A "Mute" switch of the "HI" channels allows to temporarily cut the signal to the main speakers. The subwoofer channel offers the choice of two crossover transfer functions, a level control, a subsonic protection and dynamic protection with the same three parameters control of the loudspeakers. The loudspeaker/subwoofer crossover is done with a 24dB/octave slope.

DESCRIPTION OF CONTROLS FRONT PANEL A) 1) B) SUBWOOFER SELECTOR: Selection of type of subwoofer: The block of switches on the left allows the selection of the type of subwoofer. The choice is based on the size of drivers and their acoustic load: the labels "18" "15" "46" "38" refer to the products reference. The "S" switch must be engaged if the subwoofer's reference includes one.
DESCRIPTION OF CONTROLS FRONT PANEL C) SYSTEM OPERATION: 6) HF EQ: This pot controls the clarity of the system, adding or subtracting HF energy via a "tilt" filter. The range is from -6 to +6 dB. 7) MON/FOH: This switch engages equalization, optimized for near-filed applications (stage monitor, distributed sound).
DESCRIPTION OF CONTROLS REAR PANEL 13) Normal/Bridge: this switch must be engaged when using a bridged amp (32db gain) 14) Sub Input: When this switch is released, the subwoofer derives its input from the sum of inputs A and B; when it is engaged; it receives the signal from an external source (such as a mixer's auxiliary send). NB: For proper operation of the protection circuitry, the gain of the amplifiers must be 26dB. Most amplifiers provide this gain as standard.
