Leprecon LP-750 Series - Manual (Page 2)

THE LP 700 SERIES OPERATIONAL INSTRUCTION BOOKLET
The LP-700 series is a two scene control board that can be broken into 7 basic sections.
The LP-700 series has a 6 channel chase, a bump system that can change the existing
look on stage momentarily, as output trim section, a master section, a dipless crossfade,
a delay timer with progress meters and an individual channel adjustment section. Also
the LP-700 series has a 12 volt dimmable gooseneck work lamp.
The series uses a power source of 105-125 VAC 50-60 HZ and its output is a continuous
DC voltage across all channels.
POWER UP
When the power is applied to the controller the dimmable gooseneck work lamp is
accessible through the power “on” switch. This lamp is available in two different
wattages, 2.4 and 5 watt. The 2.4 watt bulb is standard equipment in all of our
controllers. (If you require more light output, then you can order the “High Intensity”
conversion kit.) You may adjust the intensity of the lamp by a clockwise rotation of the
knob marked “lite”. (See figure A)
To engage or disengage the controller simply push the rocker switch marked “on”. The
green LED marked “power”, located beneath the switch, will be illuminated at this time.
If the LED is not glowing recheck your power cord and be sure the outlet that you are
using is operational. If the outlet is operational and the power LED and work lamp are
not working, you may have an open fuse. The fuse is located inside the controller and is
mounted to the circuit board.
TRIM ADJUSTMENT
Under the “power” LED is another green LED marked “max”. This LED’s brightness is
directly related to the amount of trim, the factory adjustment is 10 volts, and is accessible
from the recessed trim pot located next to the LED.
Under the “max” trim control is another recessed control for the minimum output voltage,
this is marked “min” and is factory adjusted to zero volts.
*Do not readjust* either of these controls unless there is a reason for the adjustment,
such as the implementation of another brand of dimmer. Do this only with a volt meter
connected to the output of the controller. We will cover the procedure for trim
adjustment later on in more detail.
CHASER
The chase section, which has two control faders and a switch, is located next to the
power section. (See figure B) On the rear of the controller is a series of group selector
switches. (See figure C)
