Introduction
Web Based Mini Stereo Power Amp
The RM523 and AMP523 are web based input control units, allowing the connection and
control of several stereo audio source devices (such as CD-player, Tuner, MP3 player,
... ) and a microphone.
They both have 4 Stereo Line Inputs, 1 Stereo Line output and 1 Balanced Microphone
Input with Phantom Power performed together on a 18-pins terminal block connector.
A line level output has been provided as alternative output, to link the output signal to
external devices such as recorders or amplifiers.
The RM523 has an output performed with an RJ45 connector. This output is a dif-
ferential audio output with increased voltage level, meant to connect the RM523 unit
to the LX523 active speaker system. Because of the differential signal and increased
voltage level, the maximum cable distance can reach a cable length up to 500 meters
over CAT5 cabling and makes the signal insensitive for noise and interference caused
by external devices.
The AMP523 has an amplified stereo speaker output with a power of 2 x 15 W power.
The amplifier construction is based on Class-D technology ensuring a high efficiency
and reliability.
The input switching, volume regulation and other functions control can be done in se-
veral ways. Using a web-browser it can be controlled from any computer in the same
network as the AMP523 or RM523. An RS232 and RS485 control port allows the in-
tegration and control of the device in any home or industrial automation system and
tablets or smartphones can be used to control functionality by using one of the specially
developped Apps.
To make the installation even more complete, an optional MWX43 or MWX45 wall panel
can be installed to control the signal routing and volume level from one or multiple fixed
locations.
