LDP1.0

Description

The LDP1.0, is a complete pack including an induction loop amplifier LD1.0, a 100 meter loop cable spool, a loop receiver OP-FSM-02 with headset, a transportation case with wheels, a connection panel and a pack of audio link cables.

The LD1.0 supplied in this package is an high efficiency class D amplifier, with a 92% efficiency. It guarantee an optimumpower for medium and large rooms up to 250 m².

This device is composed of 2 inputs (combo and terminal block), switchable into a line or microphone and a priority 100V input.

The LD1.0 provides an output current of 5A RMS as well as a compressor and a AGC, ensuring an optimum audio quality. This portable solution has been designed to be temporarly installed for meetings, conferences or events.

The LD1.0 have been developed with strict and rigorous specifications that allow us to offer a 5 years warranty.

The LDP1.0M is a version with a wireless microphone supplied in the kit.
