1. GENERAL DESCRIPTION
The TOA DP-0202 (DP-0204) is a digital processor provided with a signal processing function for controlling
sound systems. 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
Digital signal processing allows setting of highly-accurate acoustic parameters.
The signal flow and signal processing functions can be set from a personal computer, and these settings can
be stored as a file for later use.
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.
Analog or digital inputs and outputs can be used as required.
Two communications ports of RS-232C (for controlling a single unit) and RS-485 (for controlling up to 30
units).
A system locking function prevents problems resulting from operation error.
Multiple signal processing functions yet space-saving design (sized for 19" rack).
Wide operating voltage range: 90 VAC-250 VAC.
2 IN/2 OUT (DP-0202) and 2 IN/4 OUT (DP-0204).
3. HANDLING PRECAUTIONS
The digital processor 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 DP-0202 (DP-0204) 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 DP-0202 (DP-0204) is a black box equipped with a signal processor. All signal processing functions and
setting value ranges are, therefore, accomplished by operating the personal computer software. Refer to the
software specifications for details of the signal processing functions.
