SOLIDYNE DH 400 DIGITAL PHONE HYBRID

The DH 400 system is a digital hybrid with DSP that allows in seconds to configure at any point of the radio through the LAN network, the telephone lines that are used for recording or for live interviews.

The DH 400 handles 4 phone lines; one of them convertible to mobile. The audio signal is digitized and processed within 4 DSP units (Digital Signal Processor). Hybrid rejection is self-adjusting and reaches values ​​of 50 to 60 dB using a technology called digital echo cancellation. The DH 400 is managed by an internal microprocessor that supports various working modes. For example, it can handle 4 Production telephones so that the telephone operators write the name of the caller on the PC screen.

The absence of line return due to the echo cancellation that the DSP algorithms perform, allows to obtain excellent audio quality. To this is added the VQR (Voice Quality Restoration) processing that allows an on-air audio quality almost impossible to distinguish from an interview conducted in Studios.
