Audio Distribution amplifier
Description The AD-125 A audio distribution amplifier is, so to speak, the central unit of the extremely flexible line level distribution system. The system serves to route line signals from mixer preamplifiers, sound source devices, etc. of up to 10 output channels (power amplifier, with 1-channel operation) or 2 x 5 output channels (with 2-channel operation). Please consider the following features: • E ach of the 10 outputs can be controlled separately. An LED overmodulation indicator is provided for the two input channels. • T he device is incorporated in a 19˝ housing with an overall height of 1 RU.
part from the numerous features such as balanced in• A puts and outputs, the audio distribution amplifier offers excellent sound characteristics. It is also distinguished by its extreme ease of installation and operation.
