Applications

The flexible DSP, remote web monitoring, and control of the DPA Series
amplifiers makes them the perfect choice for presentation rooms,
classrooms, conference rooms, and retail background / foreground music
applications.

General Description

The AtlasIED DPA Series amplifiers feature a combination of flexibility,
performance, and control to provide high value features for applications
that require more than just great sound. The network enabled DPA
series amplifiers are DSP controlled four-channel amplifiers that can be
configured in three different amplification arrangements to meet a wide
range of installation design requirements.

DPA amplifiers can be used right out of the box in their factory default
configuration as traditional four-channel 70.7V commercial power
amplifiers requiring no programming, special set-up, or network
connectivity. However, when web enabled, the DPA amplifiers can be
configured in four-channel mode with either 4Ω or 8Ω load impedances
for two stereo zones. Many system designs require both low and
high impedance amplification. The DPA series can be configured for a

70.7V/100V paging/background system on two channels and the other
two channels can be used for 4Ω/8Ω foreground stereo applications.

The DPA comes standard with four balanced line inputs and an
accessory slot for an optional DPA-DAC4 four-channel Dante™ receiver
card or a DPA-AMIX (2) mic/line and (2) AUX input card, for a total of
eight inputs. All inputs can be mixed and routed to any of the four
amplifier channels. All amplifier channels have an assortment of DSP
tools including level controls, EQs, limiters, high & low pass filters, and
delay to provide flexibility for a range of applications.

The output level can be assigned to either the front panel
potentiometers or to the onboard GUI. Wired remote level controls
can be configured to allow simple control for the end user. Each
unit also features GUI based input and output level metering along
with assignable mute functions that are triggered via an audio signal
or contact closure. Access to the DSP settings is accomplished via
computer, tablet, or mobile device using a web browser. All settings can
be password protected.

The DPA series amplifiers also include PC based site manager software
that automatically searches within a specific network for all DPA
amplifiers on the network. It will list them and allow single click access
to any unit. The DPA Site Manager software can do a variety of functions
besides locating IP addresses such as; fault reporting, input & output
status, standby status and remote activation via a scheduler timer.

The flexibility of the DPA Series amplifiers and comprehensive
assortment of local or network control configurations make them an
ideal choice in today's sophisticated commercial audio market.

NOTES:

1. Power level measurment is define as follows: 1Hz Sine wave signal burst of 20 cycles (20mS) at 1% THD+N, followed by 480 cycles of a 1kHz sine wave at 10% of the
max power. Other power measurements are available upon requests.

2. Power measurement with Ethernet connected. Without Ethernet connected deduct .2W

3. Average Power is defined as Pink Noise input signal applied to achieve 1/4 of the 4 Ohm or 70.7V power rating.

4. Max Power is defined as 1 KHz input signal applied to achieve the maxium power output before clipping into a 4 Ohm or 70.7V load.

5. BTU is calcualed by the AC Mains Power consumed minus the total power output measured at the specified load and condition, multiplied by 3.412.

Example: 785 Watts from the AC Source - 600 Watts Total Output power = 185 x 3.412 = 631 BTU

When network enabled, the amplifier shall have a GUI home page with
Input and Output active meters, Output Configuration indicators, with
Tab selections to navigate to User PC Control page, Amplifier Setup
page, Mobil Control page, IP Configuration page where I/O can be
labeled, Update page for firmware upload, and About page. All four
amplifier channels shall have an assortment of DSP tools with navigation
icons to the following individual GUI pages: Amplifier Configuration,
Mute, Link & Ports Assign, I/O Router Assign, Hi & Lo Pass Filters,
5-Band Parametric EQ, Output Level, Delay, and Limiter.

The amplifier shall have four (4) rear-mounted Control Ports to allow
assigned/configured Remote Level or Mute functions to be activated
by external contact closure relay or controlled by voltage. Each Control
Port pin shall be assigned to one function such as Mute or Level, but
not both. Control Port assignment shall be done in the GUI Mute, Link,
Port Assignment Page. The factory default assignments for the Amplifier
Control Ports are assign as a Remote Level & shall be as follows:
C1 controls Output 1, C2 controls Output 2, C3 = controls Output 3,
C4 controls Output 4. The Control Ports shall provide +10V and GND
connections for Remote Level Control Port using 10kΩ Linear Taper pots.

The amplifier shall have Site Manager software to perform a variety of
functions including locating DPA amplifiers' IP addresses; fault reporting,
input & output status, standby status, and remote activation via a
scheduler timer.

The amplifier shall be an AtlasIED DPA804.
