Architect and Engineer Specications
The power amplifier shall be a 4-channel switch mode power amplifier with
efficient BASH Hybrid topology output circuitry with a Global Switch Mode
PFC power supply. The amplifier shall be configurable as 4-channel low
impedance 4Ω or 8Ω mode, 2-channel high impedance 70V/100V mode,
or 2-channel low impedance 4Ω or 8Ω and 1-channel high impedance
70V/100V mode. The amplifier shall be factory shipped pre-configured in a
two-channel 70V/100V mode. The I/O Router shall be configured as follows:
Input 1 routed to Outputs 1 and 2 and Input 3 routed to Outputs 3 and 4
and will not require a computer or network to use in default mode.
The performance specifications shall match or exceed the following:
70V/100V x 2CH = 1200W; 4Ω x 4CH = 500W; 8Ω x 4CH = 300W, (ref.
specification Notes 1-4 above); Input Sensitivity 750mV Balanced, 0dBU;
Input Impedance Balanced 40K Ohms; Max Input Level channels 1-4,
+14dBU, 7dBU inputs 5-8 with Dante
™
; THD 1% at rated output, .2%
Typical; Frequency Response -3dB 20Hz – 20kHz (DSP set to flat); Signal
to Noise Ratio -100dB Below Rated Output –A Weighted; Crosstalk >70dB
@1kHz; Protection circuits =Thermal, Short, Signal Limiter; Sleep Mode
(Ethernet Active) 2.2W, 8BTU; Standby/ADP mode 19W 65BTU; Max Power
All CH driven 70.7V/100V (default mode) = 1245W, 1818BTU. Dimensions: 2
x RU, 19" W x 3.5" H x 14.5" D. Weight 20.8 lbs.
The power amplifier shall have a front panel power switch and three states
of idle power, Idle Active Mode, Sleep Mode, and Standby Auto Power
Down (APD) Mode. Each mode shall have an LED indicator on the front
panel illustrating the power status. When in Sleep Mode, the Ethernet shall
remain active for access to the amplifiers on board GUI.
The amplifier shall include convection cooling with dynamic fan assist for
extreme conditions. If the unit is not being used or in Standby mode, the
fan shall not be needed for cooling and shall remain Off until the unit is in heavy
use. As heat is generated in the amplifier during use, the fan shall activate
at a low speed and increases as needed to keep the amplifier at safe
operating temperature. The amplifier’s air flow shall be from rear to front.
The front panel controls shall consist of four (4) volume controls that can be
removed and replaced with included security covers. Above each volume
control, LED indicators for Signal and Limit/Protect/Mute shall provide the
amplifier output operating condition. The 4-channel output operating mode
shall be displayed to the right of the output indicators using multicolor LEDs.
These indicators illustrate if Channels 1/2 and 3/4 are low impedance 4Ω or
8Ω individually configured or combined making a 70V/100V output. Amplifier
operation mode settings shall be completed using the internal DSP GUI.
On the rear panel, the amplifier shall have an IEC AC receptacle that
operates from 110V - 120V & 220V - 240V and shall automatically sense the
AC Mains voltage and change voltage settings. A removable AC Mains fuse
shall be provided for protection.
The rear-mounted Input connectors for inputs 1 - 4 shall be individually
removable 3-way 3.5mm Phoenix type connectors that accept balanced line
input signals (+) (–) and (GND) pins and will support unbalanced signals by
connecting the (–) and (GND) pins together. The amplifier configuration and
I/O Routing shall be done in the GUI. Any Input shall be capable of being
routed to any Output.
The rear-mounted Output connector shall be a screw terminal block type for
connecting speakers to the amplifier. The recommended wire to use shall
be Class 3 rated,14-gauge wire or lower for speaker wiring. Amplifier output
channel configurations shall be done in the amplifier GUI. The amplifier shall
be shipped with two speaker output terminal covers for safety. Included
in the carton with the amplifier shall be eight (8) spade crimp terminals
that accept 12-gauge wire and four (4) security cover screws (M3 x 8mm).
Terminal block screws shall be M4. The amplifier shall be pre-configured at
the factory for two-channel 70V / 100V mode.
The amplifier shall have one (1) rear mounted Accessory Card Slot to
add accessory modules. Accessory modules shall make available four (4)
additional inputs (for a total of 8) that can be routed to any of the four output
channels. Optional accessory cards shall be a Four-Channel Dante
™
Digital
Audio Input Card and a Four-Channel Analog Mic / Line, Auxiliary Input Card.
The amplifier shall have a rear-mounted Ethernet Connector to connect to
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 4 (QTY) 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 DAP2402.
