intelligibility and sound quality in acou

TOA again leads the way in ensuring optimal
commercial sound audio, with an easy-to-operate
digital audio processor outfitted with an 8-input/
8-output capability, an ARC that incorporates the
latest technology, and such features as gain,
equalizer, crossover, compressor, noise gate,
matrix and delay. The DP-K1 is equipped with
TOA's new Automatic Resonance Control (ARC)
function, which automatically measures and

processes the acoustic resonance
characteristics of complex environments and
provides compensatory parameter settings.

This latest addition to the TOA line of commercial
sound digital audio processors makes it easy to
bring optimal sound enhancement even to such
as houses of worship, sports facilities, convention
center, airports and many other venues.

Operational versatility for wide-ranging
applications.

Working in tandem with the unit's 8-bus matrix capability,
the DP-K1's modular design allows up to 8 line/mic inputs
and 8 line outputs, as well as flexible contact/closure
remote control. The ARC function, along with gain,
equalizer, crossover, noise gate, matrix and delay
functions, can be applied to each of the 8 inputs and
outputs. To ensure extra-precise versatility, six separate
modules are available
for both input and
output, plus one for
remote control
operation.

Examples of signal flow.
Users can choose from among
16 different combinations.

Automatic parameter adjustments ensure
clear sound, simply and easily.

After obtaining measurements of the acoustic
characteristics of the venue, the Automatic Resonance
Control function automatically measures frequency
characteristics of the broadcast area and finds resonant
frequencies. It then creates an equalizer that curbs
resonances, to improve speech intelligibility and sound
quality. Up to now, acoustic compensation has been
manually carried out and time-consuming, but TOA's
proprietary ARC technology allows the task to be
accomplished with
easy operation
and in a short
time.

Quick and easy setting of parameters
via a PC.

Settings for signal flow, matrix, digital signal processing
and ARC operation can be performed easily on a PC via
Ethernet. Up to eight parameter-setting patterns set for
different purposes can be stored in memory.

Rack mounting available in three sizes.
