The H8000FW houses two independently running DSPs (digital signal processors). They are lovingly referred to as "DSP A" and "DSP B." Although they are both always running, you can only view the parameters for one DSP at a time. Use the PROCESSOR A/B key to toggle the display between the two DSPs. (Both DSPs can be combined to run a single, "monolithic" program - see below.)

Each DSP runs "programs" that are stored in the system. "Programs" are the algorithms that manipulate your audio. With the exception of "large sampler programs" and some "long delay" programs, any program can be run on either DSP. Like two separate effects boxes, the parameters for the program running on DSP A are totally independent of the parameters for the program running on DSP B. Like two separate effects boxes, you can connect the outputs of one DSP to the inputs of the other, or use them completely independently.

Some processing-intensive programs are designed to run on the resources of both DSPs. These "monolithic" programs use the input/output routing of DSP A. While a monolithic program is running, all parameters for DSP B disappear.

DSP A and DSP B each have eight "virtual" inputs and outputs, which can be patched to the eight main inputs, each other, or any of their outputs.

See the inserted routing guide for complete routing details.

Never lose sight of the above facts!!! They are the foundation upon which we will build our understanding!!!

Knobs, Keys, and Jacks

If this is your first time learning the H8000FW, don’t be put off by some of the rather indepth descriptions that will follow; they exist for your future reference (once you understand the H8000FW and need a quick bit of information). For now, concentrate on the names of the various knobs and jacks. Their use will be explained progressively throughout the rest of this manual.

The Front Panel

inputs, DSP B's eight inputs, DSP A's eight outputs, DSP B's eight outputs, or the eight main outputs.

See The Level Meters on page 72.

B) System sampling rate and external sync indicator

The top four LEDs display the system sampling rate of the H8000FW: 96kHz, 88.2kHz, 48kHz, or 44.1kHz. When solidly lit, they indicate that the system sampling rate is exact (+/- 0.05%). When blinking, they indicate that the system sampling rate is between one of the fixed rates (the LED corresponding to the nearest sampling rate blinks). The bottom LED, EXT, reflects the current external sync status.

See Understanding the "System Sampling Rate and External Sync Indicator" When Using the Internal Clock on page 83.

See Understanding the "System Sampling Rate and External Sync Indicator" When Using the External Clock on page 87.

C) BYPASS Press this key to bypass or mute the H8000FW. This key behaves differently depending on the settings made on the bypass menu page in the LEVELS area.

See Bypassing and Muting on page 90.

D) Bypass Status LEDs

A illuminated = DSP A is bypassed

B illuminated = DSP B is bypassed

both A and B blinking = system is bypassed

See Bypassing and Muting on page 90.

E) SOFT KEYS These four keys select the menus or events described immediately above them on the bottom line of the display.

See Understanding the Display and SOFT KEYS on page 16.

F) THE DISPLAY The display tells you what’s going on. In the upper left-hand corner of the display is either the letter "A" or "B" or nothing at all. "A" indicates that what is shown on the display reflects the status of DSP A. Similarly, "B" indicates that what is shown on the display reflects the status of DSP B. When neither letter is shown, the H8000FW is running a "monolithic program" that uses the processing resources of DSP A and DSP B. (Note: the menu pages in the BYPASS, LEVELS, and SETUP areas have some displays that are common to both DSPs. In these areas, the "A" or "B" is irrelevant. However, in the PROGRAM, PARAMETER, and Patch Editor areas, menu pages are DSP specific.) The remainder of the top line displays the name of the program running on the currently displayed DSP and the current display area you’re working in. The bottom line is dedicated to the four SOFT KEYS directly below the display. The middle section of the display changes depending on what you’re doing!

See Understanding the Display and SOFT KEYS on page 16.

G) PROCESSOR A/B Press this key to toggle the display between the status of DSP A and DSP B. The upper left-hand corner of the display changes when you press this key; the "A" toggles to "B" and vice versa. Both DSPs are always running, but the display only shows the parameters pertaining to one of them at a time. If you're running a "monolithic program," this button does nothing.

H) PROGRAM/ROUTING Press this key briefly to access program functions such as loading, saving, deleting, etc. The DSP you are loading into or saving from is referred to in the left-hand corner of the display ("A" or "B"). To load into or save from the other DSP, press the PROCESSOR A/B key. If you load a "monolithic program" (indicated by a roman numeral "II" next to its name), it will effectively load into DSP A, and DSP B will disappear. If you load a "normal" program next, it will load into DSP A, and the "Thru'" program will be loaded on DSP B.

See Program Load, Save, Delete, Etc. on page 115.

Press and hold this key for one second to access the Routing Storage area where "routing configurations" are loaded and saved.

See Signal Flow Example on page 64.

Press and hold this key again for one more second to access the Setup Storage area where "setup configurations" are loaded and saved.

See Storing and Loading Setups on page 137.

Press and hold this key again for one more second to access the Usergroup Storage area where "usergroup" files may be renamed or deleted.

See Using User Groups to Organize Useful Programs on page 44.

See Miscellaneous Setup Options on page 138 to change the "one second hold time" required to enter the above areas.

I) PARAMETER/PATCH EDIT Press this key briefly to access parameters for the programs that are running. The parameters shown are for the program running on the DSP referred to in the left-hand corner of the display ("A," "B," or nothing at all for monolithic programs). To see the parameters for the program running on the other DSP, press the key.

Press and hold the PARAMETER key for one second to access the Patch Editor. The patch shown is for the program running on the DSP referred to in the left-hand corner of the display ("A," "B," or nothing).

See the separate Programmer’s Manual for Patch Editor information.

See Miscellaneous Setup Options on page 138 to change the "one second hold time".

J) SELECT Press this key briefly to select something highlighted by the cursor or to load a program on the PROGRAM screen.

Press and hold this key for one second to set up a remote control for whatever parameter is highlighted on the display.

See Remote Controlling Parameters on page 111.

See Miscellaneous Setup Options on page 138 to change the "one second hold time".

K) CURSOR KEYS Press these keys to move the cursor on the display. The RIGHT CURSOR key moves the cursor right, the LEFT CURSOR key moves the cursor left, the UP CURSOR key moves the cursor up, and the DOWN CURSOR key moves the cursor down. (We only break from this convention in the case of loading programs, where the left and right cursor keys do some more interesting stuff!)

See Using the Cursor Keys, the SELECT key, the NUMERIC KEYPAD, and the KNOB on page 19.

L) THE KNOB Spin the KNOB to change the value of whatever parameter is highlighted.

See Using the Cursor Keys, the SELECT key, the NUMERIC KEYPAD, and the KNOB on page 19.

To change the "one second hold time," alter the "key hold" parameter on the [misc] menu page in the SETUP area (you may have to press the SETUP key several times to find it).

M) BUSY LED If a Memory Card is in place, this LED illuminates when data is being written to the card. Don’t remove the Memory Card if this LED is lit! If no Memory Card is in place, this illuminates when data is present at the MIDI In port or at the serial port. Use the latter feature to troubleshoot communication problems between the H8000FW and the rest of the world.

N) MEMORY CARD SLOT Insert a Memory Card here to add new programs or to save your own.

See Memory Cards on page 47.

O) MEMORY CARD RELEASE Press this key to release the Memory Card (but don’t press it if the BUSY LED is lit!).

P) The NUMERIC KEYPAD

Use the numbers, decimal point, and minus sign to enter numeric values or to enter numeric text in a text field.

CXL "Cancels" the last entered digit. It’s like the backspace key on a computer.

/ KEYS Use these keys to increment or decrement a parameter’s value. When entering the name of a program, the  key toggles between capital to lower-case letters and the  key toggles between "insert" and "overwrite" modes.

ENT (Enter) After you’ve entered a numeric value with the NUMERIC KEYPAD, press ENT to enter it. In many contexts, ENT behaves just like the SELECT key.

See Using the Cursor Keys, the SELECT key, the NUMERIC KEYPAD, and the KNOB on page 19.

Q) POWER Flip this switch to bring the H8000FW to life! When the power is off the unit is bypassed, i.e., most audio inputs are connected to their corresponding audio output.

R) LEVELS Pressing this key accesses menus for metering and levels.

See Controlling Levels on page 72.

S) SETUP Pressing this key accesses menus for routing, digital configuration, MIDI configuration, service utilities, data dump utilities, and program advance options.

The Back Panel

OPTIONS

a) AC VOLTAGE SELECTOR

Line up the dot with the triangle so that your preferred voltage is up. It is absolutely essential that you select the voltage corresponding to your local AC power! Check this carefully before first powering the unit, and after moving to a different country.

b)FUSE HOLDER A 1-Amp Slow Blow fuse. Always replace it with the correct value.

c)AC PORT Connect an IEC standard 3-prong AC power cord here. The center post is

chassis ground.

AES/EBU Digital Audio Input/Output (Professional)

Use these connectors to connect professional digital audio gear to the H8000FW. These cables are differential with a shielded twisted pair. Eventide recommends the use of purpose-manufactured Digital Audio cables, which have low capacitance and a controlled impedance to better carry AES signals. Ordinary microphone cables will usually work at 48kHz, but are likely to reduce range and add jitter and possibly distortion to the signal. It is unlikely that long lengths of microphone cable will prove satisfactory for 96kHz operation.

d)

Connect these inputs and outputs to other AES/EBU-specified gear. If the parameter DIN 1/2 on the inputs menu page in the

SETUP area is set to AES/EBU, then digital inputs 1/2 are accepted at AES/EBU input 1/2 jack.
