A proper time alignment in the vehicle is essential for a perfect stage image. The adjustment without any tools is time consuming and imprecise; the „tape measure“ method works quite well, but requires fine adjustment by ear and thus offers an additional source of error.
The actual sound source of a single loudspeaker or an entire speaker system is decisive for the amount of delay to be set. Passive two-way systems are often used, especially in simpler configurations, which makes a correct setting even more difficult.
The ATM performs an acoustically correct time measurement and thereby also takes into account the run-time differences in a passive system.
With the proprietary “ATM“ method, Audiotec Fischer offers the possibility of an autonomous measurement of the required delays for each DSP channel. This works with all devices that can be configured with the DSP PC-Tool.
