AZTEC Power Amplifier MA-400
• With two types of input jacks (balanced XLR and balanced phone) and three types of output jacks (Speakon, 5-way binding post, and phone), the MA series is suitable for a wide variety of applications and installed systems.
• The unit offers three operating modes: STEREO (where CHA and Ch2 operate independently), PARALLEL (where the unit outputs a CHA source through twin amplifier systems, Volume control independently), and BRIDGE (where the unit operates as a single high-power amp).
• Each channel is equipped with an independent SIGNAL/CLIP/Protect switch indicate.
• The Protect indicator lights upand sound output is automatically mutedwhenever the unit’s protective circuitry is operating.
Variable-speed low-noise fans ensure high reliability when the unit is running hot.
These MA -series amplifiers fully incorporate own technological expertise, and of fer high reliability,rock-solid stability, and superb acoustic characteristicsall in a trim, 2U/3 U sized package.
