Description

The ISA 4D32 is specifically designed for installation applications.

In just 1 RU, it offers smaller dimensions, lighter weight and the traditionally amazing sound quality and reliability of all Outline products.

ISA 4D32 amplifiers implement a high efficiency microprocessor controlled power supply with built in PFC (Power Factor Correction) that allows flawless worldwide operation with any AC mains voltage in the range 90-264 VAC tolerant to peak up to 400 VAC.

The patented SRM (Smart Rails Management) technology allows to maximize the efficiency of the system and drastically reduce power consumption at any load and usage condition.

A secondary high efficient power supply is present to keep the system responsive at any operating condition, so that system check and monitoring can be performed even in stand-by and deep-sleep modes.

This amplifier is designed to work with lo-Z (from 2 Ω) and with 70V/100V distributed lines: any mixed configuration of low and high impedance output loads can be realized, making the ISA 4D32 suitable to applications in installed audio systems.
