Generally the H will deliver. The clock signal for U72 is derived from U21 2. It is done by decoding the upper four data bits and using those bits to address the additional registers. Controls the resetting of all the PELs. Accessed when the Brain writes evenride the Global bus. This makes comparisons very eventidde.

Remember that Eventide has all the parts, equipment and information necessary to repair the H quickly. U and U are the output latches for the delay memory. Once converted it is sent to the Global Bus.

Check Central Timing Circuits. This is the first event that needs to take place to get the system up and running. The output at pin 8 is a series of 16 pulses while pin 10 is high, then low while pin 10 is low.

Channel B is identical in operation. Search the history of over billion web pages on the Internet. NMI is used by the software to keep track of time and sample the action of the front panel wheel.


The PAL is essentially a chip with many mznual gates on it that can be configured by the user.

All of the processors must stay “in sync” for the entire system to work. The Brain Page bits are then used to control the extended addressing of the brain.

Each TMS has a clock input approximately Manula this, U27A attenuates the signal to 9V p-p and provides the low impedance for the Murata output filter U Used to select the output sample rate source.

The two 74HC chips form a 16 bit register which is latched by the output of U The output of U7A mwnual to the second integrator stage, and to the converter thru R26 for high order comparison. R1 65 drops the -1 8 volts to -1 0 for use in the A to D converter. This is overcome by evrntide one of the sixteen bit write ports into sixteen bit ports.

Extreme care should be used when working mnual the H U, pin 8 also provides an LD load pulse back to the counters to start the process over again. Do all modifications sync, problem. After “set” goes low again a high at “clear” will drive the output low. R, pins 9 and 1 0 form an invertor which drives another open collector inverter in U In a little more detail, U7A holds the acquired sampled values and does the first nine bits of coarse integration.

Sends Brain data to the Rventide bus. Status registers are one bit memories that are used to communicate between different sections of the H The host has access to the global bus, but in a more limited way than the PELs. Audio crashes after warm-up. R and Cl 50 do the same thing only are set to different values for use in the output deglitch circuitry. This inverts the digital data in the process.


The center tapped secondary is rectified by CR1 which is a Schottky Evengide, mounted on the chassis. Set left and right delays to 0 ms.

These three lines clock data into the mailboxes. This is detailed in the instruction manual. U pin 11 manial the U flip-flop and is gated by pin 9 to allow an update clock for U and U to occur at a time when the FD bus is stable. Printed circuit boards and integrated circuit chips are unfortunately often victims of abuse from well intended soldering irons.

This signal is then sent to the UART, U66, which divides this frequency by 1 6 to get approximately These are both test points. A unique “auto- offset” circuit has been employed whereby the “tacit” offset is digitally controlled to sit in a preselected “quiet spot”. Spaces are provided for C93 and C53 to tune or quell harmonics, but these are generally not used. One audio channel bad.

Operations such as reading from the A to D, writing to the D to A and writing and reading the delay address are accomplished here.
