DESIGN FEATURES
Physical Design
The amplifier is enclosed in a metal (steel) case of 2U height. The amplifier is
designed to be installed into a standard 19" rack.
The amplifier must be fixed at four points, when installed in the RACK 19 "(two points in
front and two at the rear).
Power Supply Unit
Two independent switch-mode PSU. Individual for each pair of channel.
Cooling System
Forced, cooling rate smooth adjustable system.
Two powerful fans. Backward air flow direction.
Dust Filter
Two removable filters are located on the front panel under protective covers.
Covers can be removed and installed without the use of any tools.
Power Amplifier Units
RX9d
amplifier is based on a modern, high performance D class topology.
This topology provides high efficiency, low heat generation and large output power At
the same time, the high switching frequency of the output stage (450 kHz) provides sound
quality comparable with the best analog amplifiers.
Analog inputs
The amplifier is equipped with four balanced analog inputs ( XLR female).
The use of balanced inputs provides for an essential reduction of the environment-
induced hum and noise interference with long input connecting cables.
For DSP processing, the analog signal is converted to digital using four 24-bit A/D
converters, operating at 96 kHz. The dynamic range of A/D and D/A converters is 120 dB.
AES inputs
Inputs of channels 1 and 2 can be switched to digital input mode.
A digital AES/EBU two-channel audio signal can be applied to each input. Sound
signals can be sent to an amplifier from a digital mixing console or other device, that
generates a digital audio signal AES/EBU (AES3). The AES/EBU inputs have balanced
transformers and are protected against static electricity. Built-in sample rate converters
support a wide range of input formats (16-24 bit / 44.1-192 kHz), converting any of them into
internal format 24bit / 96kHz.
ETHERNET connectors
Two equivalent ports for connection to the ETHERNET network.
Provide the ability to configure and remotely control the amplifier over a network, using
the NetControl software. The built-in router allows you to connect multiple amplifiers in
chain.
Line Outputs
Four XLR connectors (male).
Provide the possibility of parallel connection of several amplifiers, using standard
signal cables.
