Overview and Functions
The unit shall comprise a two-in/two-out digital loudspeaker drive
processor with power amplifier outputs. Additional capabilities and
facilities shall include analog and AES inputs (with redundant failover
from AES to analog), and a software controlled four-channel input
mixer. Further required is Ethernet-based control and monitoring
of internal parameters from a remote computer. All control and
monitoring shall be remotely accessible via a custom software
interface compatible with both Windows and Mac operating systems.
Digital Loudspeaker Processing
The unit shall include comprehensive digital audio processing
configured specifically for loudspeaker drive applications. Four
discrete equalizer sections shall be included, one for each input and
output. Each section shall facilitate 10 parametric equalizers with
the ability to set each equalizer curve to bell, notch, high shelving
or low shelving as required. A two-channel crossover section shall
accommodate adjustable delay with up to 2 seconds per input
and output and also include output limiters with limiting response
configurable by entering only values for total output power at the
selected nominal load impedance.
Power Amplier
Maximum total output of both channels shall be 2400 watts. In
discrete two-channel mode, each amplifier channel shall deliver
maximum continuous power as follows: 300 watts into 16 ohms;
600 watts into 8 ohms; 1200 watts into 4 ohms; or 800 watts into
2 ohms. Maximum output voltage per channel shall be 100 V peak;
maximum output current per channel shall be 20 Arms. Levels shall
be adjustable in the DSP across a range of infinity to 0 dB.
Input Impedance shall be 18 kOhm. Performance parameters shall
be as follows: THD+N (20 Hz - 20 kHz @ 1 W) less than 0.1%;
THD+N @ 1 kHz, (1 dB below clip), less than 0.05%; frequency
response (-3 dB) of 2 Hz – 42 kHz.
Connectors, Network, and User Interfaces
The rear panel shall provide audio inputs for analog (2) and AES
digital (1) with input signals on XLR-F connectors. Link outputs for
all three inputs shall be on adjacent XLR-M connectors. One RJ45
Ethernet jack shall be provided for networked monitoring and control
via remote computer (PC or Mac). The unit shall be compatible with
use as part of a low-latency, self-configuring digital audio network
that supports sampling frequencies from 44.1 to 96 kHz. Output
connectors on the unit shall be both binding post and Neutrik

(2 x NL4). The front panel user interface shall include a
high-brightness LCD panel, a rotary encoder, two mute buttons,
menu button, and back button. The user interface shall be menu-
driven, with all functions of the digital loudspeaker processor and
the power amplifier accessible via screen displays configurable with
the menu/back buttons and rotary encoder. Multicolor LEDs shall
indicate presence of any warning or fault conditions. The unit shall
be supplied with a custom software program for comprehensive
monitoring of system status and operating parameters, as well as
control of DSP and amplifier functions. The software program shall
be compatible with use on a Tablet PC or Mac.
Power Supply and Cooling
The power supply shall be a universal type with AC line input
between 100 and 240 VAC at 50 or 60 Hz. The amplifier shall be
cooled by one temperature-controlled, variable-speed fan, with
airflow from front to back.
Physical
The unit shall be 483 mm (19 in) wide, 44 mm (1.75 in / 1 U) high, and
431 mm (17.0 in) deep including handles and rear support. Weight
shall be 6.2 kg (13.7 lbs). The chassis housing shall be black/grey
painted steel with black anodized aluminum front and handles. The
unit shall be approved for use as specified by CE, PSE, UL 60065,
CAN/CSA-C22.2, No.60065:03, FCC part 15 Class A, EN 55103-1,
EN55103-2, and ROHS.
The unit shall be the Lab.gruppen IPD 2400.
