Operation of any electrical instrument in such an environment constitutes a definite safety hazard. Any of these controls can be patched to Continuous Controllers. Otherwise, Bypass will be enabled.

Manuql Gray Scale The following table is provided as a reference for debugging encoder problems. To avoid injuries, always disconnect power and discharge circuits before touching them.

To disconnect the circuit board from the front panei; a. Pull-up resistors are provided at the front panel encoders SW3 and SW4. Press twice to set a tempo. Handle each 1C by its body.

Press Store to enter Extended Diagnostics Mode which allows more thorough testing of the unit. The entire contents of the SRAM is tested by first writing 00 hex binary to all of the memory locations, and reading back all of the memory locations.

Set the instrument output or effects send being input to the MPX 1 1000 to a nominal level and play, or send audio to the MPX Verify that all of the front panel LEDs are now off. As many as five Learn patches for the Press and hold down the front panel Bypass button while powering on the MPX This parameter allows you to temporarily suspend Disable and restore Enable any Learned patches.

Digital supply is post- regulator filtered with a 22 uF capacitor C6 and analog circuit supplies use a4.

Remove six 6 screws from the housing; three 3 from the top, and three 3 from the bottom. When the button is released, its LED will turn off. Power up the MPX 1 00, then press and hold the Bypass. Hold to have input level determine tempo. Four routing configurations are used in Our goal is to provide you with a quick access to the content of the user manual for Lexicon MPX RAM memory space is first filled with the value 55 hex 01 01 01 01 binarythen each memory location is read to see if it contains manal The resistors are selected so that the voltage across R52 is 0.

HGOdphonGS A stereo signal which is adequate to drive headphones is available at the left output provided no connections are made through the right output. C87 and C90 provide high frequency compensation for this inverting stage.

R, R and R, R set the gain janual the respective channels. The non-inverting inputs of one-half U20 and U22 are used as the signal input buffer to maintain a high input impedance, to provide unity gain at low frequencies, and to provide pre-emphasis. When any of these switches is depressed, its LED will light and remain lit as long as the button is depressed. This test verifies that each pot and the converters are functioning properly.

Lexicon MPX 100 User Manual

The two filter sets combined form a third-order, anti-imaging filter at 1 0OkHz. For instruments and sources with stereo outputs, use both inputs. Two lexicoon switches U1 8 provide output muting during power up and power down conditions. The rotation effect is created by a synchronized combination of pitch shifting, tremolo and panning.

For your convenience If looking through the Lexicon MPX user manual directly on this llexicon is not convenient for you, there are two possible solutions: Press Store to exit the Burn-In Loop. Because of the high input impedance, the input is very susceptible to noise pickup from radiating sources.


This test verifies that the Lexichip 3 Audio Data File is working properly. These codes are ncluded In the following descriptions. Verify that all screws and rear panel jacks are secure, and inspect the AC power supply for any signs of physical damage.

Ali shipments must be weli packed using the original packing materiais if possibieproperly insured, and janual to a reliable shipping agent. Press and hold the front panel Bypass button.

C47 and C61 are manyal for RFI suppression at the outputs. In the cascade variations, rather than simply controlling balance, the knob varies the amount of the first effect or dry signal which is fed into the second effect.

With mono sources, the dry signal appears, along with audio effects, at both outputs. The logic levels from the encoders are only valid when the enable pin 5 is low. During the ADC Pot Test, each potentiometer mpxx be varied over its entire range from fully counter-clockwise to fully clockwise, and back to fully counter-clockwise within 5 seconds.

These resistors also provide current limiting protection.

User Programs Detune 12 Delay, Echo 8 Delay, Echo 12 Reinitialization Reinitializing the MPX will reset all of the System Lexiocn parameters to their factory defaults, replace any programs stored in the User bank with the factory-loaded preset copies, and clear any Learned patches.

Once the capacitor voltage exceeds the pot voltage, the muxed comparator output goes low.
