DESCRIPTION

The DACsys
DSP processors that provide more than 20 different types of
all-digital signal processing functions for audio system sig­nals between the mixer output and the power amplifiers.
They are designed to provide highly flexible configurations
to meet a wide variety of applications including performing
art centers, houses of worship, sports facilities, theaters
and, now, touring sound applications with the DP-0204SR.

Incorporating a wide range of sophisticated parameter con­trol for the various processing functions, TOA’s DSPs set
the standard for digital processing in both quality and quan­tity of tools available to the user. For example, you can have
up to 68 full parametric EQ filters simultaneously on-line in
one DP-0204. Each unit, or a system comprised of up to 30
devices, is controlled using an intuitive, user friendly graph-

ic PC interface. This software allows easy access and

changes to any of the processing functions and configura-

tions to meet almost almost any system requirement. In

addition, it provides off-line editing and data file storage of

system set-up. The signal flow and parameter settings can

also be easily stored in and recalled from each device’s 16

non-volatile memories. The hardware is space efficient and

is designed to prevent unauthorized changes to the pro-

cessing via multiple levels of security. By using units either

singly or linked in multiples, systems of almost any size or

configuration can easily be designed, set-up, and installed.

ARCHITECT’S AND ENGINEER’S
SPECIFICATIONS

The unit shall be an all-digital signal processing system pro­viding comprehensive post-mixer signal processing for sound rein­forcement, production systems and touring sound applications. The
unit shall have 2 inputs and 4 [2] outputs for analog or digital audio
signals. There shall be 16 non-volatile memory presets for storage
and recall of different processing parameter settings. The unit shall
incorporate all solid state circuitry.

Nominal analog input sensitivity shall be: +4dBu (maximum
+23dBu), 10k ohm input impedance, electronically balanced.
Maximum gain shall be 18dB (6dB analog plus 12dB digital). Hum
and noise shall be at least 105dB IHF-A below maximum output.
Frequency response shall be +0/-1dB (ref 1kHz) from 20Hz to
20kHz. Analog power outputs shall be nominal +4dBu (maximum
+24dBu) into a 600 ohm load, electronically balanced with less than

0.05% THD at 1 kHz. Analog to digital and digital to analog conver­sions shall be done with full 20-bit resolution.

The inputs shall be switchable to accept either analog or
digital audio signals. The outputs, independently of the inputs, shall
be switchable to emit either analog or digital audio signals. Digital
inputs and outputs shall be provided with a TTL level sensitivity and
75 ohm input impedance.

The signal processing functions shall be inscribed in
replaceable firmware (EPROM) within the unit. This will allow
upgrades to and changes in the unit’s signal processing functions.
Digital processing functions shall include: gain; attenuation; polarity
inversion; parametric and graphic equalization; signal delay; com­pression; limiting; noise gate; low and high frequency shelving boost

filters; low and high frequency shelving cut filters; crossover filter
slope and type; all-pass filtering; notch filtering; and uniform directiv­ity horn EQ. Parameters and parameter ranges for processing func­tions typically shall be quantitatively variable in ways beyond what is
normally available for similar analog functions.

All signal flow and processing functions shall be externally

configured, programmed and controlled through the RS-232C or RS­486 ports. The RS-485 ports shall provide the means to link up to 30
units together with control by one external computer. With the exter­nal computer control disconnected, the memory preset selection can
be made globally for all units by changing the preset on the desig­nated master unit. The RS-232C port shall allow external control of a
single unit. Units may be subsequently linked using the RS-485 ports
for global memory changes and full control of all units.

Computer software for use with a PC shall be provided to

configure, program and control the units. The software shall be a
graphical Windows-based program that allows downloading and
uploading of configuration and parameter settings and has the capa­bility to store settings as binary files. The program shall provide
graphical representations of the configuration showing the signal flow
and signal processing functions; dialog boxes showing all parameter
setting for each processing function; listing of units in the system; and
listings of memory presets. a graphical plot of both frequency and
phase response shall be provided for individual equalizer processing
functions, and for input-to-output for each output channel. The soft-

ware shall provide functional lock-outs under hardware switch set-

tings and password protection to prevent unauthorized changes.

The AC line mains shall be 50/60Hz, 100V-240V and power

consumption shall be 36W. The digital signal processor shall be

enclosed in a durable, painted, black, 0.04 in steel enclosure

mechanically reinforced by a 0.08 in. thick, black anodized, alu­minum front panel. Overall dimensions shall be 19” w x 1.74” h x

12.9” d. Weight shall be 11 Ibs. Standard E.I.A. rack-mount hole
spacing shall be included. The digital Signal Processor shall be the

TOA model DP-0204 [DP-0204SR, DP-0202].
