Inputs in parallel mode
Inputs in parallel mode can be used if you want to drive both channels with one signal, without the need for link- or Y-cables.
Bridged mono mode
Bridged mono mode combines the output power of the two amplifier channels into one loudspeaker load, resulting in twice the voltage swing and four times the
power in a specific load.
SDP Speaker Drive Processor
The SDP circuit can be seen as the “brain” of the amplifier. By means of speaker-specific modules, that are located in 2 front-accessible slots, the characteristics
of the connected speaker are loaded into the amplifier. With this, the amplifier is “tailor-made” to the speaker, regardless of the power output specifications of the
amplifier.
Multiple processing functions are operating at the same time;
- protection: The speaker is protected against damage from over-excursion and power overload.
- dedicated filtering: The fixed cross-over settings cater for the best system performance.
- optimised power response: The SDP module adjusts the RMS and peak values to the speakers capacity, giving maximum system power output.
- system equalising: This circuit equalises the system response, with utilising the maximum component efficiency. This results in higher overall system sensitivity
and reduces the need for active filtering while offering efficient amplifier usage (passive system).
High efficient Class-G power stages
The ALC2 is equipped with two class-G power amplifiers for increased thermal efficiency, while also saving weight on the heat sinks and the power supply.
SIS Signal Integrity Sensing
SIS is a unique feature installed in all Alcons amplifiers that senses the signals arriving at the loudspeaker terminals, and so compensating for errors introduced
by cable resistance and self-induction. Doing so, SIS maintains low linear and non linear distortion, compensation of signal loss and high damping figures, thus
achieving high signal integrity, regardless of the cable length.
