The TOA DP-K1 is an easy-to-operate digital audio
processor equipped with gain, equalizer, crossover,
compressor, noise gate, matrix, delay and Automatic
Resonance Control functions. The advanced new Automatic
Resonance Control (ARC) function enables the DP-K1 to
automatically measure and process the acoustic response
characteristics of complex environments and provide
compensatory parameter settings to improve speech
intelligibility and sound quality. This latest addition to the TOA
line of digital audio processors makes it easy to bring optimal
sound enhancement even to acoustically challenging venues
such as houses of worship, sports facilities, convention
centers, airports, and many other venues. The DP-K1's
modular design supports up to eight mic/line inputs and eight
line outputs with flexible contact-closure remote control.

DP-K1
FEATURES
Digital audio processor has built-in rack-mount brackets (3
RU, EIA standard 19 inch rack mount width) for
commercial sound applications such as houses of
worship, sports facilities, convention centers, airports, and
many others.
Cost-effective modular design — up to 8 inputs and 8
outputs
• Users can choose from among a variety of optional modules.
Up to 16 different user-created combination configurations
are possible.
Built-in gain, equalizer, crossover, compressor, noise gate,
matrix and delay audio processor functions
Eight bus matrix allows flexible input-to-output signal
routing for zoning or room combining.
PC software for offsite programming and settings
Network interface for remote programming and
maintenance
Network ports are available on both front and rear panels.
8 internal memories for storage and recall of different
signal routing and parameter configurations.
Preset knob-lock function prevents accidental errors during
operation.
Input and output channel indicators
Cooling fan ensures continuous, reliable operation.

Advanced new Automatic Resonance Control (ARC)
function improves system intelligibility.
• The ARC function automatically measures frequency
characteristics of the broadcast area and finds resonant
frequencies.
•Automatically creates a filter curve that curbs unwanted
resonant frequencies for the measured room response.
•Improves speech intelligibility and sound quality in facilities with
challenging acoustic environments.
• Room mode compensation
• Unlike earlier, time-consuming manual adjustment methods that
required electroacoustic engineers, operation is quick and easy.
• Fully comprehensive operating capability means no dedicated
device is required

D-936R
4 stereo input
module equipped
with standard RCA
jacks. This module
features two stereo
transmission
mode:
1) Selection of one
of the four stereo inputs.
2) Mixing of all four stereo inputs,
transmitting the mixed signal to the
D-901 though left/right channel
outputs.
D-937SP
Single channel stereo digital input
module. With the use of this module,
digital signals can be input, permitting
direct connection of the D-901 to
equipment having a digital output.
Owing to the built-in sample rate
converter, the module can handle
signals of various sampling frequencies.
D-923AE
2-Channel digital input module. With
the use of this module, digital signals
can be input, permitting direct
connection of the D-901 to equipment
having a digital output. Owing to the
built-in sample rate converter, the
module can handle signals of various
sampling frequencies.
