TTL31-A Active Two-Way Array Module

The TTL31A is a "mini" size 2 way line array.

TTL31-A Active Compact Line Array

The very high output and dynamics, the extreme accuracy and high frequency extension, plus the very compact size make the TTL31A the ideal tool for indoor applications, live performances and events.

Digital processing: The integrated digital processor is based on a state of the art 24 bit, floating point DSP running at 96 KHz sampling rate. The calculation capacity largely exceed the processing needs and the DSP is never pushed to the limit. Crossover and equalization of the 6 transducers, limiter, system presets: high pass, air absorption and cluster size corrections.

Digital power: The TTL31-A is powered by a 750 watt switching power supply and 2 digital amplifiers: 500 watt mid-bass and 250 watt compression driver. Very high output, extremely low distortion and natural sound . The amplifiers and digital processing are housed in an aluminum extrusion external to the cabinet for best heat dissipation.

Compression drivers: A new compression driver unit has been developed in RCF specifically for array applications. The best ratio between the size of the diaphragm and the overall diameter and the very small total size makes the ND1411-MT a unique driver for application in line on straight horns. TTL31-A houses 3 of them for perfect HF control.

Controlled mid-bass: One light and reliable neodymium 8", in a band pass loading configuration, provide a tight and loud mid- bass. Thanks to a careful acoustic design the sensitivity in the 100 Hz region is almost double than typical, same size, designs.

Reliable mechanics: Laser cut high quality steel bars and precision machining for an easy to use and reliable mechanics. Thanks to the very light weight of the cabinet building the cluster is very simple, fast and effortless.
