TOA DP-SP3 CU Quick start guide
TOA’s dedicated digital speaker processor creates richer,
more vibrant sound environments by
maximizing the performance of each speaker
in the system.
The DP-SP3 makes it easy to enrich and enliven
your facility’s sound environment.
TOA has launched a new digital speaker processor that
enables you to enhance your sound system easily and
inexpensively. Designed specifically to work with
speakers, the processor taps into characteristics of
individual speakers and draws out their best possible
performance, to realize richer, more expressive sound
space in a variety of venues. The DP-SP3 has a built-in
library of parameters for TOA speakers, which enables
you to enjoy well-balanced sound immediately, without
going to the trouble of inputting complex parameter
settings. In addition, a preset memory of up to 16
setting patterns allows you to instantly recall the
setting you need for a particular venue. The processor
is also packed with such essential audio processing
functions as Equalizer, Crossover, Matrix, Compressor,
and Delay. Affordably priced and compact, the TOA
DP-SP3 offers a solution for people who wish to add
more speaker performance to their sound system.
Enhanced Sound-Space Creation
Ease of Use
• DP-SP3 processor with TOA speaker equalizer characteristics
library, for easy and full access to speaker performance
capabilities, plus upgrading for new speaker models.
• 24-bit, 96 kHz sampling for clear, high-quality and realistic
sound, with a full sense of presence.
• Full array of essential audio processing tools: Compressor,
Parametric Equalizer, Output Delay, and Mute.
• 10 filters on each input and 12 filters on each output. Any
combinations of parametric equalizer and high/low pass, and
high/low shelving filters, as well as all-pass, notch filters and
CD horn equalizer are possible.
• 2 inputs & 6 outputs, and processor can work with a 3-way
multi-amp system.
Wide Range of Applications
• Suitable for applications in venues such as banquet halls and
houses of worship, gymnasiums, and medium-sized restaurants.
• Setting and operation via a LAN
on a PC with installation of the
provided intuitive control/
operation software.
• Preset memory for up to 16 different
setting patterns, for instant recall
of patterns best suited to a
particular venue.
• Built-in library of parameters for TOA speakers.
• Flexible remote control operation:
• 4 contact input terminals, for memory recall, output volume control,
and output muting.
• Switching of preset parameter patterns, speaker EQ pattern selection,
and matrix selection by a Web browser via Ethernet.
• 2-way linkage with M-864D digital mixer's preset switching possible.
• Setting of input sensitivity with input PAD switch.
• Analog output attenuator.
