LP-C12

The Yorkville Sound LP- C12 is a highly flexible stage lighting controller that doesn’t sacrifice ease of use to achieve a wide range of functionality. With twelve channels of lighting control and a broad assortment of chase, audio, and other effects to choose from, the LP-C12 has what it takes to get you through nearly any job you can throw at it. The LP-C12 can be used to control any combination of the Yorkville LP series light bars, including the older LP302 and LP304. Please note that the LP-C12 will not work with other brands of lights that use DMX control.

Quick Start

1. Connect a standard XLR cable from the LP-C12 to any compatible Yorkville lighting product (LP-LED4, LP302 and/or the LP304).
2. Plug the light bar into a standard 3-pronged grounded AC receptacle, both the light bar and the controller (which is powered from the light bar) will turn on.
3. Push the Scene 1 button on the controller and set up your lights for your first scene (the color control is active only for the LP-LED4 and other LP-LED color controllable products).
4. Changes to a scene are stored in memory in real time, so you don’t need to do anything to store the scene you’ve created. The next time you load Scene 1, it will come back just as you’ve set it up now.

Hint: The factory preset scenes and some of the effects patches were created with the assumption that lights 1-4 and lights 5-8 are set at the front of the stage facing back on performers and lights 9-12 (if used) are set up shining on the rear wall behind the performers.

Basic Operation

The LP-C12 was designed specifically to work with the Yorkville LP-LED series products like the LP-LED4, but it was also designed to be backward compatible with our legacy LP302 and LP304 light bars. All of the functions described here are the same for all Yorkville
lighting products except where specifically noted.

1. Channel Controls
   The channels are grouped in three rows of four controls, with each row corresponding to one of the XLR outputs on the rear of the controller. Each channel has two controls:
   Color – This rotary encoder is used to select the color of the corresponding light. (The LP302 or LP304 lights will ignore the color control)
   Intensity – This control is used to set the brightness of the corresponding light head. When this knob is pushed down, it will momentarily
   flash the corresponding light to full intensity.
   There is a yellow LED indicator on each channel that illuminates with a brightness corresponding to the brightness of the light on that channel.

2. Scene Selection
   This bank of thirteen scenes allows you to store your favorite or most frequently used lighting scenes in the LP-C12’s internal memory for instant recall at any time. To recall a scene, simply push the corresponding button, and the lights will change to your stored setting. Changes to scenes are stored in real time; to save a scene all you need to do is select the scene you wish to change and make your changes.
   The LP-C12 has a scene auto-advance feature. This feature moves through the scenes from Scene 6 to Scene 13, and then back to 6 again. If you look at the controller, you will notice that Scenes 1-5 are grouped together, and Scenes 6-13 are together. This arrangement is to help you remember which scenes the auto-advance feature uses.
   Hint: Use scenes 1 to 5 for special scenes like when the leader of the performance is talking to the audience or to highlight solo portions of the performance. Set scenes 6 to 13 to vary generic lighting of all the performers. This way when using the Auto Scene Advance the solo lighting scenes will not be used.

3. Functions
   Effects – Press this button to engage effects (see next section for description of effects). If this button is pressed when the effects are on it will turn off the effects and return to the active scene. The channels that receive effects are selected by the effects Patch control. The type of effect is selected by the effects Select control. The effects operation is described in detail later.
   Flash: All White – This function momentarily turns on ALL connected lights to white.
   NOTE: For LP302/LP304 the flash function will not change the color of the lights. Whatever gels are in use will be the colors that are flashed by this function.
   Flash: All Red – This function momentarily turns on ALL connected lights to red.
   NOTE: For LP302/LP304 the flash function will not change the color of the lights. Whatever gels are in use will be the colors that are flashed by this function.
   All On – This function turns on all lights to a pre-determined color (different colors on each channel). If this button is pressed while already in the ALL ON mode the All On mode will be cancelled and the unit will return to the active scene.
   NOTE: For LP302/LP304 the colors will be determined by the gels in use rather than by the program.
   BLACKOUT – As its name implies, this function will turn off ALL connected lights. Pressing this button again will return to the active scene, exiting the blackout mode.
   Auto Scene Advance – This feature causes the controller to automatically change through your preset scenes, starting with Scene 6 and going through to Scene 13. At the end of the cycle, it goes back to Scene 6 and continues.
   The timing knob directly above the switch for this feature controls how frequently scene changes occur. It offers scene-advance speeds from 3 seconds up to 10 minutes. At its center position, it is calibrated to approximately 1 minute intervals. This mode does not cancel the effects mode, blackout or all on. Effects will continue to operate in this mode. This allows effects an auto scene advance to operate simultaneously. Channels that are not selected by the effects patch will light according to the active scene as selected by the auto scene advance.
   Fade Rate – When scenes are changed, they fade from one color to the next; this controls the duration of that fade. Effects Speed – This knob controls the speed at which effects operate. This control also affects the fade  rate, including the fade rate of audio effects.

4. Effects
   To turn the effects on depress the EFFECTS button. The indicator beside the button will light to indicate that the effects are active. Depressing the EFFECTS button while the effects are on will turn off the effects and return the control of all channels to the active scene.

5. Effects Patch
   The Effects Patch control determines which channels will be controlled by the effects. This allows the user to send effects to certain channels while leaving others as determined by the active scene. Setting the Patch control to ALL CHANNELS will send effects to all channels. Other positions will send effects to one or more light bars, leaving the remaining bars controlled by the active scene.
   The positions marked Bar 1, 2, 3 TMB and Bar 1, 2, 3 TBb are intended to be used with the four channel audio effect. TMB is Treble, Mid, Bass, in this case 90 Hz bass. TBb is Treble, bass and bass. B is 90 Hz bass and b is 45 Hz bass. In most music the 90 Hz bass hits first and the 45 Hz is the fade out of the bass. In some music these will be separate beats. Some music will have very little 45 Hz content and will not often trigger the blue lights. Each Bar is one band and all the lights on one bar go on together. The patch position marked Ch. 1, 2, 7, 8 spreads the effects over two light bars leaving two lights on each to illuminate performers. The position marked Bar1, Bar2, 9-12 is intended for use with audio effects, it will flash one whole bar with the 90 Hz bass, another bar with 45 Hz bass and the remaining bar (if used) will show 3 or 4 channels depending on the audio effect selected. The Position marked Ch. 3, 4, 5, 6, 9-12 sends effects to all but four lights.

6. Effects Select
   The effects on the left hand side of the control and bottom are not affected by the audio input. The effects on the right hand side and top of the control are affected by the audio input. The four-band and three-band audio are full range effects, while the remainder of the audio effects are 90 Hz only.

7. Chase
   There are four non-audio Chase functions differing only in color. The colors chase has 7 colors so that each head flashes in many colors before repeating. The speed of the non-audio chases is controlled by the effects speed control. The fade rate varies with the effects speed adjust. The lower end of the chase speeds can be used as a color fade effect, changing colors ever 20 seconds but with only one light one at a time.

8. Color Fade
   The color fade function will change the colors at a slow rate, with all the lights the same color. The effects speed control sets the change time. The fastest change will be every ½ second. The slowest is approximately every 4 minutes. With the control in the middle the change is every 15 seconds.

9. Strobe
   The strobe function is white only and operates from one flash every 3 seconds to 6 flashes per second controlled by the effects speed control.

10. Audio Chase
    The audio chase has 7 colors and advances on the start of each 90 Hz audio beat. The fade rate is affected by the effects speed control. Setting the effect rate control in the middle is optimum for normal operation.

11. Audio 4 Bands Slow
    This is the classic Color Organ function, but implemented with DSP technology to increase the response to transients and to allow each channel to continuously adjust the gain. The high band is 8 kHz to 15 kHz and the mid band is 700 Hz to 3 kHz using IIR filters. The high bass is centered at 90 Hz and the low bass is centered at 45 Hz both using FIR filters that respond in about ¾ of a cycle. The fade rate is determined by the fade rate control. This effect can be made significantly faster with the fade rate control. The low bass is blue, high bass red, mid green and high yellow-orange.
    NOTE: FIR and IIR stand for Finite Impulse Response and Infinite Impulse Response. These are common terms for digital audio filters.

12. Audio 3 Bands Fast
    This is similar to the function above but with the audio midrange band excluded and the 90 Hz high bass channel routed to 2 lamps per bar. This creates a display with more emphasis on flashing with the music beat. The low bass is blue, high bass red and high is green. The fade rate is faster but can be slowed down with the effects speed control.

13. Flash Colors
    Lights are flashed two at a time modulated by the bass beat. The pair colors are rotated in 5 steps and 7 steps to create pseudo random color pairing. The position pairing repeats after 6 steps.

14. Flash All Colors
    All four lights are flashed modulated by the bass beat. There are two lights of each color with the colors rotated in 5 steps and 7 steps to create pseudo- random pairing.

15. Flash All Red
    All four lights are modulated in red by the bass beat.

Rear Panel

1. Reset to Factory Presets
   This control that is accessed through a small hole in the rear panel returns all the settings and presets to the origi-nal factory settings. Normally in a rental pool of equipment this button will be used to erase any setting done by the previous user. The unit must be powered for this control to be effective. It will be necessary to use a tool to depress this control. A pen is usually a suitable tool. THIS WILL ERASE ALL USER SETTINGS AND PRESETS.

2. Footswitch Jacks
   Simple guitar dual foot-switches can be plugged into the jack on the rear panel to allow hands free operation. The alternate action switches are interpreted by the LP-C12 as if they are momentary switches. Depressing the switch initiates the same action as pushing a corresponding channel on the LP-C12 front panel. The scene up and scene down switches increment or decrement the active scene. All 13 scenes can be accessed. Incrementing above scene 13 returns to scene 1. Decrementing below Scene 1 returns to scene 13.

3. Audio In
   This jack accepts line or speaker level signals to drive the audio effects and will work with most audio signal levels.
   It will begin to work at levels as low as 30 mV but requires 75 mV to operate properly. The maximum for proper operation is 100 volts RMS. Levels as high as 200 volts will not cause damage. The inputs are balanced using the tip and ring connections. The sleeve (ground) is not fully connected in order to eliminate ground loops and prevent short circuits in miss-wired speaker circuits.

4. Lights 1-4, 5-8 and 9-12 outputs
   These connections are intended to connect to Yorkville Sound LP series lighting devices. These connections will not work with DMX devices. Signals are sent out these connections to the lights and power is provided from the lights to the controller through these connections. When used with the older LP304 and LP302 products, the gender will be reversed compared to the labeling on the lights. This controller will work fine connected to the output connections of these older units even though this is the reverse gender from the labeling.
