General Description

The AtlasIED DPA1202 features a combination of flexibility, performance
and control to provide high value features for applications that require
more than just great sound. The network based DPA1202 is a DSP
controlled 4-channel amplifier that can be configured in three different
amplification arrangements to meet the design requirements of any
installation.

The unit is factory preconfigured in a two-channel 70V mode. If the
design requires four channels of low impedance amplification, the
amplifier can be configured as 4-channel model with either 4Ω or 8Ω
load impedances. Many system designs require both low and high
impedance amplification. This unit can be configured to deliver 70V/100V
for a paging/background system on a single channel plus two additional
4Ω/8Ω amplifier channels for foreground stereo applications.

The DPA1202 comes standard with four balanced line inputs and an
accessory slot for an optional DPA-DAC4 4-channel Dante™ receiver card
or a DPA-AMIX (2) mic / line, (2) AUX input card, giving the DPA1202 a
total of 8 inputs. All inputs can be mixed and routed to any of the four
amplifier channels. All four amplifier channels have an assortment of
DSP tools including level controls, EQ’s, 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 on board GUI. Wired remote level control
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 unit also includes a 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 a 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.

a Local Area Network (LAN), computer, or router/switch using a standard
RJ45 cable to access the amplifier’s DSP and control settings.

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 you can label I/O, 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 shall be as follows: C1 Controls CH 1/2 70V / 100V Output Remote
Level, C2 Not Assigned, C3 Controls CH 3/ 4 70V / 100V Output Remote
Level, C4 Not Assigned. The Control Ports shall provide +10V and GND
connections for Remote Level controls using 10kΩ Linear Taper pots.

The amplifier shall have Site Manager software to do 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 DAP1202.
