In each block is a schematic name a word, followed by SH. Try a high output mic directly into the H and headphones plugged into the output to eliminate most variables.

Needless to say the 2 signals will most likely slide in and out of sync with time, temperature and component tolerances. Check output level settings. Phase is reinverted by the following circuitry. The crystal oscillator that drives the converter also serves as the main clock for the entire H Only 8 address lines are able to address more than 64, memory locations per internal array these DRAMs have 4 arrays hence 64 K by 4.

The nrdTtn 3 T 6 blt ‘ np 1 t WhlCh can be used as a branch condition by the processor. There are also exercises for very specific hardware areas that together with an oscilloscope can greatly aid in trouble-shooting.

Check external signal flow and balanced line connections. Here is a basic procedure to follow if an analog problem is suspected. If the jumpers are set for dBm the output will be clipping from too much gain.

H Service Manual | Eventide

It is set up as a divide by 13 circuit. This is the first event that needs to take place to get the system up and running. Enables front panel switch information to be placed on the BD bus. U4 is a hex “D” flip-flop that sends FPD signals to the matrix. It is truly the “brain” of the system. No response to MIDI input. The regulator is totally isolated from the chassis by a pad and the mounting socket.

Pin 10 of U69 is connected internally to the collector of a transistor. In a little more detail, U7A holds the acquired sampled values and does the first nine bits of coarse integration. They should not be held to any strange levels.

U buffers and inverts the analog-type signal now called CLK1. The ratio of resistors manuap the auto-offset from affecting high level signals. This is inverted by U for the left circuit and delayed by U for the right.

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. They should all be at OdB. This is the clock signal to the latches. This is the only channel distortion adjustment required. Read instruction manual sections on MIDI. The held sample is “integrated down” in two different stages of resolution by U7A and U7B. Writes audio data into the DRAMs.

U62 also decodes addresses, but it is a 74LS U is not as simple. After “set” goes low again a high at “clear” will drive the output low.

It is factory programmed to enable a system of extended addressing for the brain processor. These two latches are used to input data from the bus. They are 2K by 8 bit RAMs. In the HB the operating system can be cleared without loosing the user presets.

U83 works in the same manner but, it is an 8 bit, addressable latch. Surrounding caps are simply power supply bypass.

It is a fast way for them to communicate. One audio channel bad. The H uses three of them. U67 is used to divide the 4.

Many are mono in, stereo out which use the left channel input and shut off the right. Voltage selector switch on back in wrong position. An external trigger from the oscillator will be helpful.

Set delay parameters both to zero.
