Mounting and Handling
Normally, the H8000FW will be rack mounted in a standard 19 inch rack. If the rack will be taken on the road, the H8000FW should be supported at the rear. It is advisable to keep the rack well ventilated and in a dry, dust-free environment, so that heat and moisture won’t cause degradation of performance. Contrary to some reports, we have found that soda/beer splashed liberally about the front panel does not enhance the reliability of the H8000FW. Since the H8000FW has few internal connectors, it should hold up well under "road conditions."
Memory Cards
All functions that work on internal user memory also work on Memory Cards. The H8000FW supports Compact Flash cards (using a suitable adaptor).
The H8000FW does not support PCMCIA "Linear Flash," "SmartMedia™," "XM™" or other cards not listed above.
The Compact Flash card is used extensively in digital cameras. These can also be read by PCs (and some Macs) with the use of a low cost USB adaptor. This allows saved programs to be backed up or organized on the computer. These cards do not require a battery.
Insert a Memory Card by pushing it into its slot until it "locks" into place. The Memory Card Release will "lengthen," and the display will briefly read Checking "Memory Card". . or Checking "GTR Library". . or (generally) Checking "whatever-the- name-of-this-card-is". .
Remove a Memory Card by pressing the Memory Card Release - but don’t remove a Memory Card when the BUSY LED is lit! A program that was loaded from a Memory Card continues to run even if the Memory Card is subsequently removed. The Memory Card only needs to be in place during PROGRAM and Routing Storage area functions such as loading, Save, update, remove, etc. The BUSY LED is used to indicate that a Memory Card is being written to. However, if there is no Memory Card in place, the BUSY LED indicates data at the MIDI In port or the serial port. You may want to use this latter feature during a session that requires periodic use of a Memory Card. Simply insert the Memory Card when you need to load something from it or save something to it. Remove it when you are done loading or saving, and the BUSY LED will be available for "data indication."
47
When a Memory Card is inserted, the H8000FW may report that the card is not formatted and offer to format it. If the Memory Card has already been formatted and the format question is presented, then there is a problem. Try removing and re-inserting the card. Try blowing on the business end of the card like an old Atari 2600 game (no spittle!). Formatting will erase all programs and banks on the card!
To manually format a Memory Card, see Fixing PCMCIA SRAM Memory Card Problems on page 148.
Note: Like fine china, Memory Cards are fragile:
Treat them with respect.
Don’t lie to them.
Don’t store them on your dashboard or in your toaster.
Avoid shocking them with static electricity (or any kind of electricity for that matter).
For information about Memory Card problems and how to fix them, see 2Fixing PCMCIA SRAM Memory Card Problems on page 148.

The core of the H8000FW consists of two separate effects processors or machines, shown above as DSP A and DSP B. Each of these has eight inputs and eight outputs. Also shown are two “terminal blocks”, MAIN Inputs (shown above as Main in) and MAIN Outputs (shown above as Main out), which are used to connect to them from the outside world. Each block shown above has inputs on its left side and outputs on its right.
The MAIN Inputs block is where all the external analog and digital inputs are connected.
See Configuring the Main Inputs
Each DSP may be fed from any output from either DSP or from the MAIN Inputs block. In the interest of avoiding annoying feedback, you will not normally connect a DSP’s input to one of its own outputs, but if you really want to, you can …
See Configuring the DSP input sources
49
The MAIN Outputs block may be fed from any of the outputs of either DSP or from the MAIN Inputs block. Each channel has two inputs - signals connected to then will be added together (mixed). Be aware that if two peak level signals are added in this way, it can overload the outputs.
See Configuring the MAIN Outputs
The first four channels of MAIN Outputs feeds four analog outputs, as shown. Similarly, the second four channels feed four AES/EBU outputs. The MAIN Outputs block may also feed other outputs, to be discussed later.
See Connecting to the H8000FW’s outputs
The example above shows DSP A being fed from the MAIN Inputs block, and its outputs feeding MAIN Outputs. DSP B is shown as not used.
50
This example shows DSP A and DSP B running in parallel, both being fed from Main in and their outputs being mixed at Main out.
