LS-804-M Vocal Radio System, 4 Handheld Transmitters LAudio

The LS-804-M is a quality vocal radio system with four handheld transmitters from LAudio.

This model is perfect for vocalists and presenters of various events, and also greatly simplifies the process of controlling 4 microphones from a single receiver.

The handheld transmitter is equipped with a cardioid capsule, which provides a clear signal transmission.

The frequency range of the microphone is from 50 Hz to 18 kHz, and the response is quite flat, so that the sound of the voice remains natural.

The dynamic range is 95 dB.

The rugged body of the transmitter is made of metal, and above the power button there is a small display that shows the operating frequency, as well as the quality of the radio signal. The transmitter is powered by two AA batteries.

The receiver, also made of metal, is equipped with a power button, signal level control on each channel, as well as LED indicators that show the presence of the input signal, power supply and synchronization with the transmitter.

The display shows the operating frequency and channel number of each microphone. The rear panel provides 4 balanced outputs with an XLR connector and a Mix Out output with a 1/4" jack TS connector. The receiver can be rack-mounted if required (takes 1U).

Laudio LS-804-M has a companding system that allows you to expand the dynamic range and reduce noise. It is also equipped with a multi-level silent control scheme.
