The advanced design of the Macro 1400 makes it perfect for critical power amplification needs.

Features Of The Alto Macro 1400


This amplifier is designed for professional applications, with three levels of power. Output power is adjustable and the sophisticated protection circuits ensure trouble-free operation

Input matching allows connection with any amplifier

Excellent frequency response and sound quality

High fidelity and low noise

The input is XLR-balanced and uses a 6.3 socket for better matching

The ouput power can be switched between serial, stereo and bridged

Low noise fan for efficient cooling. When the temperature rises, the fan automatically switches to high-speed. It rotates at normal speed at other times to reduce power consumption

While on, the Clip Limit function keeps a fixed ouput. When the ouput exceeds the maximum of the amp,this changes to protect its circuits. While off, there is no such limit.

Indicator for the ouput balance, as well as status indicator of SIG and CLIP. When there is a signal, the SIG light is on. If anything abnormal happens to the circuits, the CLIP light will illuminate.

Stylish white aluminum panels with acrylic accents.

Solid, durable and rack-mountable
