1. GENERAL DESCRIPTION
A 2-unit size, digitally-controlled analog matrix unit, the TOA DX-0808 is equipped with 8 inputs, 8 buses, and 8
outputs. Using dedicated software operating on a personal computer, an operator can set each function in
detail. The settings can be stored in the component's internal memory, and the memory can be recalled from
the component even when not connected to a personal computer.
2. FEATURES
Free zone selection and level adjustment from PC.
Up to 16 setting patterns can be stored, which can be easily recalled even without connecting to a personal
computer.
The stored information can be remotely recalled from external equipment, and the memory selection status
can be output.
Expandable input and output because of eight-bus construction.
RS-485 ports control up to 30 units.
A 3-step system locking function prevents problems resulting from operator error.
Wide operating voltage range : 90 VAC - 250 VAC.
3. HANDLING PRECAUTIONS
The matrix unit has no parameter setting functions, so you use a personal computer and the dedicated TOA
software program to set the parameters.
Turn the power switch ON only after all terminals and other wires are connected.
Avoid installing the unit near a heater or exposing it to direct sunlight as this may damage the unit. Also, do
not install the unit in humid or dusty locations.
Do not jolt or vibrate the DX-0808 as it is a precision instrument.
Never attempt to service the unit yourself as opening or moving the covers may expose you to dangerous
voltage or other hazards. Refer all servicing to TOA dealers.
4. SIGNAL PROCESSING FUNCTION
The DX-0808 is a digitally-controlled matrix unit.
All parameter setting functions and setting value ranges are, therefore, accomplished by operating the personal
computer software. Refer to the software specifications for details of the functions.
