Overview

01
Suitable for Single-Phase, Bi-Phase or Three-Phase operation from 85 VAC up to 460 VAC, the X8 power supply provides maximum flexibility and versatility in any power distribution design
02
Power Load Balancing with Power Factor Correction enhances efficiency in power distribution
03
Flexible routing/mixing provided by the internal 8×8 input/output matrix, allows the user to mix and route analog and digital I/O Easy plug-and-play Dante™ networking allows easy routing of the signal from any node within the network to the GTA Otto
04
Improved reliability thanks to the customizable input backup policy that allows to automatically switch input source in case of signal failure
05
Input and output IIR, FIR, IIR+FIR equalizers and raised-cosine filters, complete sets of limiters: peak, RMS voltage, RMS current, and TruePower™
06
Full protection circuitry: over/under AC voltage; troublesome signals (clipping, VHF, long-term RMS); DC; thermal; short circuit; mute at power on/off

Description

The GTA Otto has been designed to be versatile and easy to use in any operation condition. Equally useful for most subwoofers as well as high power fullrange systems, Outline GTA Otto suites any configuration and purpose.

Ultimately flexible and safe, Outline’s power supply is now suitable to Single Phase, Bi-Phase or Three Phase operation from 85 VAC up to 460 VAC without need of selection. True Three Phase load balancing is directly achievable by the unit without any complex load assignment in the power distribution system. Outline GTA Otto provides eight fully processable channels and selectable inputs from analog sources as well as digital AES3 and two redundant Dante™ streams.

Channel mixing and routing can be easily performed thanks to the integrated revolutionary low latency DSP, providing the highest degree of freedom in sound shaping and speaker management.

Full support to 100 Mbps and Gigabit Ethernet makes it easy to integrate Outline GTA Otto into any existing infrastructure. Completely integrated into Armonía Pro Audio Suite™, the new GTA Otto interface is also available for smartphone and tablet, providing a new experience in power management.
